 * Rs 150 cr hospital meeting Green Rating for Integrated Habitat Assessment (GRIHA)

Hospital authorities said that specialities including urology, nephrology, neurosurgery, gastroenterology, medical gastroenterology, surgical gastroenterology and microsurgery would be available in the new building. Although the facilities are already available in the GRH the new facilities would be up to date. Moreover, it would be spacious to accommodate more number of patients, where they can get specialty care, said Dr S Vadivel Murugan, medical superintendent of GRH.

To a query on the number of bed at the hospital, he said, "I am not sure about the number of bed strength in the upcoming centre. The state government will soon announce the number of staff nurses and doctors required for the hospital."

Shreekar, an architect who accompanied K Nayak during the visit said the four-storied building will meet the Green Rating for Integrated Habitat Assessment (GRIHA). They expect three or four-star rating for the building. Solar panels would also be installed in the building to meet the power requirement especially for hot water and premises lighting, he added.

* India No 3, in Top 10 ranking of Green Buildings by USA

China Beats India to #2 spot on the US Green Building Council’s Top 10 List By Anshuman Magazine, CMD,CBRE South Asia Pvt. Ltd.

May 28, 2014

Quite recently the “greening” initiatives of India’s building construction industry received a boost when the country was ranked #3 among a list of the top 10 counties in the world by the US Green Building Council (USGBC) for LEED outside of the US. Canada topped the green rankings, followed by China and India. The Leadership in Energy and Environmental Design (LEED) certification, an internationally recognized standard for measuring a building’s carbon footprint, is now an accepted and acknowledged practice in India. By definition, a green building uses less water, optimizes on energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for its occupants, in comparison to a conventional building. And the LEED green building rating system advocates construction practices that increase profitability and longevity with a building going green.

The green building concept has been gaining prominence in India with an increasing number of initiatives, primarilyby the Indian Green Building Council (IGBC)—a division of the Confederation of Indian Industry (CII)—striving to impart knowledge offering advisory services to the industry on environmental aspects and practices for green buildings, energy efficiency, water management, renewable energy, green business incubation and climate change activities. Although it is easier for new and under construction buildings to adopt green technology, existing establishments can also employ several initiatives to improve their environmental performance.




 * Infosys: Ashden Award for Sustainable Buildings

:India's IT major Infosys bagged the prestigious Ashden Award for sustainable buildings, referred to as the Green Oscars,  on Thursday for its cutting-edge design of new buildings which helps keep offices cooler and maximises natural ligh


The Bangalore-headquartered firm bagged the annual award for "seizing every opportunity to reduce energy consumption in its existing buildings - from reducing the size of chiller plants for air conditioning to painting roofs white so they reflect the heat".
The Ashden Clean Energy for Women and Girls Award also went to an Indian project, Mumbai-based Greenway Grameen. The rapidly growing clean cook-stoves business, co-founded by entrepreneurs Neha Juneja and Ankit Mathur, won for its affordable cook-stoves to improve the quality of life for Indian women.
"So far the company has sold more than 120,000 stoves, thanks to clever marketing and a focus on designing a product that women actually want to use," the awards panel said.
Five Indian projects were shortlisted for this year's awards. The remaining three projects were being named runners up in their respective categories.     

Sakhi Unique Rural Enterprise (SURE), a not-for-profit social enterprise in central Maharashtra was runner up in the Women and Girls category.
SURE has selected, trained and supported more than 600 women micro-entrepreneurs to sell clean energy products like solar lanterns and cleaner cook-stoves to other women.
The Rajasthan Horticulture Development Society came in second in the 'USAID Ashden Energy for Agriculture Award' for a solar-powered water pump project.
Mera Gao Power from Uttar Pradesh was runner up in the 'Citi Ashden Award for Innovation in Finance' category for pioneering the use of unsubsidised commercial micro grids, which have so far connected more than 20,000 families to clean, affordable power.

* Energy Efficient buildings increase ROI


Anuj Puri, Chairman & Country Head, JLL India: "Almost 90 per cent of the total cost of ownership of a building is attributed to operating and maintenance costs.

For example, energy accounts for 50 per cent of the cost," he says, adding that the initial premium one pays for green buildings is recovered within five years.

High construction costs 

According to Indian Green Building Council (IGBC), a green homes rating agency, such projects have tremendous benefits. The immediate and most tangible benefit, IGBC says, is in the reduction in water and operating energy costs. Evidence also shows that these features of energy-efficient buildings are translating into greater value in the form of increased rental rates, higher sale prices, increased occupancy rates and lower operating expenses.

The LEAF House, profiled in Prefabulous Sustainable: Building and Customizing an Affordable, Energy Efficient Home (Abrams, 2010) was designed and built by the students at the University of Maryland.

This house was set on the National Mall in Washington, DC at the 2007 event. With just 800 square feet, this modular house is very versatile, with moveable walls to expand the central living area of the house. Other unique features are the glass spine, which floods the house with light and the double roof system encouraging air flow between the upper panels and the lower roof. The vertical garden provides not only esthetic appeal but also storm water management.


Louvers on the exterior of the house were designed to allow light to enter in the winter and be deflected in the warm months. The house currently serves as the office and meeting place for the Potomac Valley Chapter of the American Institute of Architects - where it will continue to educate and inspire.

Walls on two sides of the bedroom can be closed off with translucent polycarbonate panels for privacy or opened to expand the entertaining area. The Murphy bed, as well as other furnishings in the house, can be integrated into the walls to increase available space. Photo courtesy of Jim Tetro.

The 4D Home profiled in Prefabulous Almost Off the Grid: Your Path to Building an Energy-Independent Home was built by Team Massachusetts at the SD in Washington DC in 2011. This modular house is 946 square feet and it too has moveable walls. A central truss separates the private areas of the house from the public ones with a track for moveable walls. These walls contain large storage areas, provide a dropdown desk and create flexible spaces in this small space. The total cost for this house was estimated to be $267,000. After the event, the house was moved to central Maine to provide housing for a family.

The truss contains a track, which allows the homeowner to expand the two rear bedroom spaces or the public spaces. On the rear of one of the moveable walls is a dropdown desk. Photo courtesy of Jim Tetro.

First Light, a modular house built by the students at Victoria University of Wellington was shown at the 2011 SD in Washington, DC. The design of the house comes from the classic kiwi bach (pronounced batch), a New Zealand vacation house, with a strong connection to the landscape and conducive to outdoor socializing.


The timber canopy houses the photovoltaic panels and solar water heaters. It embodies part of the active and passive strategy behind the home's overall design, shading the glazing in summer months while the butterfly, slanted design aids the passive cooling of the photovoltaic panels.


The house is currently set in a beautiful beach resort in Hawke's Bay overlooking Waimarama Beach. Photo courtesy of Benjamin Jagersma.

Prispa is a modular/panelized house built by the students at The Technical University of Civil Engineering of Bucharest (UTCB), University of Architecture and Urbanism in Bucharest (UAUIM), and University Politehnica of Bucharest (UPB). This was the first house built by a Romania team for the SD event, which was held in Madrid, Spain in 2012 and was profiled in the recently published Prefabulous World: Energy-Efficient and Sustainable Homes around the Globe. The name comes from the Romanian word for porch, which is "prispa." The porch functions as a bridge between the interior and exterior of the house while also blocking the hot summer sun. In the winter, the low sun can enter the house and warm the interior black tiles, which work as thermal mass, releasing the heat later in the day when it is needed. The total cost of building this house came to about $150,000. However the team has designed a more industrialized version of the house that they would sell at a vastly reduced price. The house is currently set in Luncani, Romania and creates enough energy to give back some of it to the grid. The approval for net metering was the first allowed in Romania, an achievement that can be credited to Team Prispa.

* Wooden Skyscrapers to cool the Planet??

wooden buildings Canada

US scientists have a new green solution to urban construction: chop down trees and use the wood for buildings. Good strong timber buildings – and there are plans for 30-storey skyscrapers built of wood – would save on concrete and steel, save on carbon dioxide emissions and cut the use of fossil fuel.


The argument may seem counter-intuitive: that is because a substantial component of climate change stems from changes in land use and the loss of forests. And some researchers have demonstrated that even the most mature trees, the forest giants, can go on absorbing carbon dioxide from the atmosphere.


But Chadwick Oliver, a forester at the University of Yale and colleagues make the case in the Journal of Sustainable Forestry. They argue that if the world stepped up the harvest of the forests and used the wood efficiently then economies could save on fossil fuel, reduce carbon dioxide emissions and give people a reason to value the forests.


It works like this. Overall, trees add 17 billion cubic metres of new wood to the planet’s biomass each year. Right now, humans take about 20 per cent of this new growth – that’s 3.4 billion cubic metres – and a lot of that is burned, inefficiently as cooking fuel, or just burned.


The savings on concrete and steel happen because about 16 per cent of global fossil fuel consumption is accounted for by the manufacture of steel, concrete and brick. Factor in the need to transport building materials and that brings the fossil fuel share to between 20 per cent and 30 per cent. So wood-based construction consumes less energyfoss


Savings outweigh emissions


If humans stepped up the wood harvest to 34 per cent and used it for construction, they could reduce the use of steel and concrete, and cut between 14 per cent and 31 per cent of global carbon dioxide emissions (the authors count methane and nitrous oxide emissions as carbon equivalents in this calculation).


And of course, carbon would stay locked up in the wood in permanent structures. This would also save between 12 and 19 per cent of annual global fossil fuel consumption: the wood left over from construction could be turned into energy.


The savings on concrete and steel happen because about 16 per cent of global fossil fuel consumption is accounted for by the manufacture of steel, concrete and brick. Factor in the need to transport building materials and that brings the fossil fuel share to between 20 per cent and 30 per cent. So wood-based construction consumes less energy.


The loss of forests represents the release of carbon dioxide, but as long as the harvesting is efficient, more carbon emissions are saved overall.


Better than agriculture


But, of course, this makes forests valuable. “The study shows still another reason to appreciate forests,” says Professor Oliver, “and another reason not to let them be cleared for agriculture.


“Forest harvest creates a temporary opening that is needed for forest species such as butterflies and some birds and deer before it regrows to large trees. But conversion to agriculture is a permanent loss of all forest biodiversity.”more..



100% Renewable DATA CENTERS!!: A Success Story


SAP has set itself a goal this year to run its 16 data centres around the world on 100 per cent renewable energy, including its new Sydney data centre that opened this week.CIO Australia speaks with SAP’s global CIO, Björn Goerke, about the different tools and techniques he is using to green the cloud provider’s data centres worldwide and drive down power costs.Half of our SAP’s energy consumption comes from its data centres, says Goerke, with 11,000 physical servers worldwide supporting its internal IT, production and software development units.

“We are also expanding into Latin America, we’re building our presence in Asia Pacific beyond Australia, and we’re going into Russia and India,” says Goerke.By 2020, SAP wants to reach the same level of carbon footprint it had in 2000 (336 kilo tonnes). SAP’s Integrated Report 2013 showed that absolute carbon emissions increased by 12 per cent during 2012 to 2013, with greenhouse gas emissions increasing from 30 grams CO2 per euro of total revenue to 32.4 grams CO2 per euro. However, overall it has reached 43 per cent of its goal to go back to a carbon footprint of 336 kilo tonnes, Goerke says.Since the start of 2008, SAP’s combined energy efficiency initiatives have contributed to saving of about A$386 million. A substantial piece of that figure is attributed to greening its data centres and making them more efficient.

“In our German data centre alone, we have reduced our power consumption by 50 per cent,” says Goerke.Besides purchasing renewable energy certificates – a subsidy mechanism for using renewable energy such as solar, wind, biomass and geo-thermal – Goerke is using a number of techniques to drive efficiencies and reduce power consumption.The first is cool aisle containment that prevents the mixing of cool and hot air so servers do not have to be re-cooled over and over.

“If you put some servers in a large room and try to cool them down, then you are cooling a much more volume of air than is necessary. So you are containing the cold air into a certain space around the servers, and you make the space you need to cool down as small as possible,” says Goerke.The positioning of the racks and servers, as well as making them as dense as possible also helps make the cooling process more efficient, Goerke says.“There’s a standard way to put them in. What we figured out is if we rack these systems in the opposite way, we can get a much better cooling effect. So the positioning of the servers had an impact on cooling.“It’s the density of the servers in the racks themselves, too. Depending on generation of hardware you use and what vendors you work with, there are different densities you can get in terms of blades or server cartridges that you put into the racks. We are also getting those down in size so that you can put more cartridges in and reduce the volume that you need to cool down,” he says.

Maximising the performance of systems through parallel processing is another way to drive efficiencies, Goerke says. SAP is using Intel’s latest generation processor – Ivy Bridge – to distribute more data onto cores that process it simultaneously, making it “eight times faster” than with older central processing units (CPUs).“From a performance perspective, the new CPU is much more energy efficient and more powerful than the previous generation," he says.“But there are certain workloads that cannot be done in parallel because it is dependent on something else. So the problem is that sme tasks have to be done in serial if you’ve got an algorithm or calculation or something.

“The good thing with in-memory platform is the way we have stored data in there and the way we have structured it so you can really divide the workload across many CPUs and parallels.“For example, I could have 200 billion of data entries I could scan in a single second. So there’s enormous computing power because you can split up the set of data you look at, distribute it across the cores, and get the result back together again.”One of the most important ways to reduce energy consumption, increase efficiencies and drive down cost is to monitor the energy usage of your infrastructure, Goerke says.

“We have only a single data centre we’ve built where only the concrete, the bunker is owned by us and that’s the one we have at our headquarters in Germany. What we put in is our infrastructure, and… we connect that infrastructure to our central management hub where we monitor server availability, heat maps to give a sense of how the servers are utilised and the utilisation level, etc.” more...


 Honda Smart Home : A Self Sufficent Green Home

honda smart home

  • Honda just launched its “Honda Smart Home”, a self-sufficient home that produces more (renewable) energy than it consumes. The home is also three times more water-efficient than a typical US residence.


  • The home features a wide range of technologies that we expect to see (combined) in many homes in the near future: A solar PV system, a battery, LED lighting, an electric vehicle and a heat pump.


  • A 9.5kW solar photovoltaic roof system generates energy for heating, cooling, ventilation, lighting, hot water and appliances.


  • In the garage, a 10kWh battery energy storage system stores the (surplus) of electricity generated by the solar system, ensuring that there is enough power supply at night.


  • LED lighting is used throughout the home and is five times more energy-efficient than conventional lighting.


  • Integrated in the home’s design is a Honda Fit electric vehicle. It can be fully recharged in approximately two hours directly from sunlight, when the solar panels are generating electricity at full capacity.


  • Eight 20-foot deep boreholes in the back yard allow a geothermal heat pump to harness the ground’s thermal sink to heat and cool the floors and ceiling throughout the year.


  • An impressive 96% of the waste directly associated with the construction of the home (drywall, brick, plastics and lumber) was recycled.


  • The home will function as a ‘living laboratory’, where the company, along with researchers from UC Davis and utility company Pacific Gas and Electric (PG&E), will evaluate new technologies relating to housing, transportation, energy and the environment.

So Many Benefits For Green Buildings  In India : Report

Many of you will agree on the fact that nowadays, plenty of renowned real estate builders with their innovative approach are coming up with a thought of making green buildings in India which not only look beautiful, but are resourceful also. However, whether you are developing a commercial or residential building you require both, natural as well as man-made resources. And, it would not be wrong to quote that green buildings can easily make efficient use of both. If we talk more in detail about the term green or we can also call it sustainable also, it states that the design, construction, maintenance, occupancy and deconstruction of a building are accounted in such a ways that it should promote long-term benefits to owners, occupants and society as a whole.

Moreover, via this unique initiative the builders leave no stone unturned in order to minimize the environmental impact and help in improving the long-term and economic performance of newly renovated projects. With the help of this initiative people can experience a better lifestyle and can live in a better tomorrow. People can live in a serene and pollution free environment and can experience the change. Hence, with this initiative these reliable makers are providing you with a healthy and safe environment so that you can spend the rest of your life peacefully.

Following are the benefits and impeccable features associated with sustainable buildings:

The cost of these edifices might be more upfront for you, but they provide you with the lifelong benefits. If we talk about a project, there is an approach that applies to a project life cycle, cost analysis so as to determine its appropriate up-front expenditure. However, these cost saving methods can fully realized only when they are incorporated during the projects conceptual design phase. Hence, this integrated system shows that the edifice is being designed as one system rather than a collection of stand-alone ones.

Furthermore, an ideal green edifice helps in many ways such as-

Increases the productivity by using less water and energy. 
Reduces operational and energy cost and better indoor as well as outdoor environmental quality
Better health and well being of the occupants
Creates less environmental impact 
Last but not the least, helps in enhancing the marketability of the building itself

Precautionary Measures: Safety is undoubtedly of utmost importance, so if there is any kind of dearth of a labourer during the construction, that edifice will never receive a green certification.

The site of the construction plays a pivotal role because technically the site should be in a centralized place so that the residents can use public transport instead of fossil fuel vehicles. 
The utilization of energy and water should be less.
Maximum efforts should be made during the construction phase like- how to recycle the resources. 
For better insulation and heat rejection, the maximum usage of aerated concrete blocks should be done.

Hence, at the end it can be concluded that these leading builders via green building concepts in India are doing every possible bit to protect the environment so that every individual can live in a better tomorrow.

Green home made of fermenting straw : simple and brilliant   Waseda University © Waseda University


We know that composting is good for our gardens, but what about heating our homes? Harnessing the heat generated by the composting process to heat our homes sounds like a far-fetched idea, but it's been proposed before and experimented with quite successfully decades ago.

Students at Japan's Waseda University built this intriguing prototype that is heated by composting straw encased within acrylic boxes that make up the house's perimeter walls.

© Waseda University

Seen over at Inhabitat, this simple home uses a simple, low-odor composting technique called "bokashi" (meaning "fermented organic matter"), the fermenting straw releases a lot of heat -- 30 degree celsius (86 degree Fahrenheit) heat, in fact -- for up to an impressive four weeks.

© Waseda University

Designed by student designers Masaki Ogasawara, Keisuke Tsukada and Erika Mikami, the "Recipe to Live" house is located in Taiki-cho town on Hokkaido island, a place that is known for its dairy farms (and lots of locally-made straw).

In the summer, straw will dry inside transparent window shelving which act as "heat shield panels," thus releasing moisture that will help cool the ambient temperature. During winter, the fermenting straw will give off heat thanks to the microbial process that gradually breaks down the organic matter. Courtesy : Tree Hugger

Live-Lib, a concept for a two-part residential building, could form part of a sustainable future for the city of Paris.


Small capsule-like homes where management of utilities, such as electricity and water, is left to the city could form part of a sustainable future for Paris, according to a team of the city's designers and architects. Live-Lib, a concept for a two-part 


The thinking behind Live-Lib is to promote sustainable sources of energy while providing a solution for low-cost living in densely populated areas where residents might move frequently. The concept comprises two structures – a central, multi-functional tower called "the hub" contains systems for energy production, ventilation, electricity, water and waste, with the expenses managed by the city.

On the outside, it features a number of ports where individual "capsule" homes can be plugged in. The capsules are privately owned and entirely the property of the resident. The inhabitants access the shared services provided by the hub through the plug exchange, where usage is also monitored and the residents charged accordingly.

Technical details regarding power generation and energy usage for Liv-Lib are scarce at the moment, but we can expect to learn more in June this year when the team showcases the concept at the 2014 Solar Decathlon Europe that invites teams from around the world to demonstrate full-scale concepts of functional solar-powered homes.more..


Indian Factory Awarded LEED Gold Status

The Indian Green Building Council awarded Shairu Gems’ new diamond factory “LEED Gold status.” The Leadership in Energy and Environmental Design (LEED) is an internationally-recognized rating system for the design and construction of energy-efficient and high-performing buildings.

Located in Surat, Shairu Gems’ building is the first and currently the only diamond factory that has attained such recognition. This demonstrates the commitment of Shairu Gems’ management toward sustainable development and corporate responsibility.

The certification of Shairu Gems’ diamond factory was based on green design and construction features that non-exhaustively included the following:

- Energy efficient building structure planning, such that 90 percent of the space has access to outdoor views and daylight, or a green facade of creepers to reduce heat of outer walls;

Chennai adopts Energy Conservation building code

Is tamilnadu following karnataka foot steps?

Newly constructed commercial buildings in the city will soon have to adopt designs to conserve energy.Officials from the Chennai Corporation and municipalities in the State participated in a stakeholders meet this week to shape the Energy Conservation Building Code (ECBC) for new commercial buildings across the State.“About 6,000 commercial buildings in the State are likely to be covered by the code,” said an official of Tamil Nadu Electrical Inspectorate. The code, being drafted under the Energy Conservation Act, 2003, seeks to reduce energy consumption of commercial buildings by 40 per cent through the adoption of various designs.

In the city, about 2,500 commercial buildings will fall under the code. The structures to be covered include buildings that have a connected load of 100 kilowatt (kW), or use or intend to use a contract demand of 120 Kilo-volt Ampere (kVA) and above for commercial purposes.

After the code receives a nod from the State government, the newly constructed commercial buildings are likely to save considerable amount of energy. The design changes include the envelope of the building and systems pertaining to heating, lighting, air-conditioning and water supply, said officials of the Tamil Nadu Electrical Inspectorate.

The impact of the code is likely to be significant in Chennai that has the largest number of such buildings in the State.

The Tamil Nadu Energy Conservation Building Code is likely to be notified shortly, officials said. The Tamil Nadu Electrical Inspectorate will coordinate the energy conservation measures of various agencies. Courtesy: Hindu



Bosch ltd plans to venture into Energy efficient green buildings

Bosch Limited, the Indian subsidiary of the world's biggest supplier of car parts, plans to earn more revenue from its energy solutions business as the company prepares to make it among the three leading players in the country by 2020 and help the company expand its business in the non-auto business. 

The new business vertical of the company, formed last month in India, and in 2011 in Germany, aims to offer energy efficiency solutions to commercial buildings in the northern capital region and Bangalore in the south. "We have set a vision, by 2020, we want to be among the top three players in the country in the energy service space," said Venugopalan CM, head of energy division at Bosch India. 

"Our focus area for the first three quarters of this fiscal year will be India. We have a team of 50 in the energy division and we remain optimistic that by the year 2020, the market for this would almost double," Venugopalan said in an interview. 

Commercial buildings in the country consume 20-25% of energy while industries consume another 15%, making global firms, including Siemens and homegrown Voltas, offer solutions to make buildings consume less energy.  more...



*Uncertified LEED buildings more energy saving than certified LEED certified buildings?: USA


The email from Banks Woodruff popped up last week, titled LEED Certification Fails to Increase Energy Efficiency. The first paragraph: 

Today, LEED Exposed, a project of the Environmental Policy Alliance (EPA), released research showing that large privately-owned buildings in Washington D.C. certified under the U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) standards, actually use more energy than uncertified buildings.It didn't really seem worth covering; the site gave no information about who was behind it, got most of the facts wrong in its exposé of the "arbitrary point system" including my favorite, the famous bike rack point, years out of date.


Who's behind LEED Exposed? 

It wasn't exactly an august organization either, this Environmental Policy Alliance; their website was just registered on February 5 and LEED exposed just registered on December 13. Woodruff's isn't even on WHOIS yet. Their website listed no staff or address or board of directors, they barely existed.


Google maps/Screen capture


A google search on the phone number of Banks Woodruff shows him operating out of the offices of the Center For Consumer Freedom, described as "a pro-food-and-beverage industry front group that attacks anyone who criticizes smoking, fast food or alcohol" on Berman Exposed, a site devoted to the antics of Richard Berman. They describe Berman as..


...a regular front man for business and industry in campaigns against consumer safety and environmental groups. Through his public affairs firm, Berman and Company, Berman has fought unions, Mothers Against Drunk Driving, PETA and other watchdog groups in their efforts to raise awareness about obesity, the minimum wage, the dangers of smoking, mad cow disease, drunk driving, and other causes.


What are they claiming?


Researcher Anastasia Swearingen claims that "LEED certification is little more than a fancy plaque displayed by these ‘green’ buildings", and compares energy use intensity (EUI) of LEED certified buildings to non-certified buildings. Quoting data from the Green Building Report for the District of Columbia, she concludes that "For LEED-certified buildings, their EUI was 205, compared to 199 for non-certified buildings. Ironically, USGBC’s headquarters (which has achieved the highest level of LEED certification) is even worse at 236."


© The USGBC office really packs'em in tight


In fact, this is often the case, because LEED buildings are newer and modern office planning packs people in more tightly, with more computers, so that they use more energy per square foot. (This was a serious debate in New York City) Employees today have a big plug load, so since last summer in New York, EUI has been used to attack green building. Nothing new here.


Marisa Long of the USGBC notes that this is a distortion:


The claims made by the fictitious organization “Environmental Policy Alliance” are false. As a recent report by the District of Columbia states, Washington’s commercial buildings are exceptionally efficient, scoring on average 77 out of 100 on the ENERGY STAR scale, well above the national median score of 50. Commercial buildings in the District of Columbia have reduced their energy consumption by an average of six percent from 2010 to 2012. These positive results are due in large part to the District’s use of LEED, the most widely used global green building program.


By the way, Swearingen is as versatile as Berman in her critiques; here she iscomplaining about spot checks for drunk drivers on holiday weekends for the American Beverage Association. These are professional astroturfers, hired guns for industry. Courtesy : Treehugger



Karnataka approves energy conservation building code 


Minister for Energy D.K. Shivakumar on Tuesday said the government has approved the Energy Conservation Building Code (ECBC) and it will be applicable for new commercial buildings with more than 500 sq mt floor area across the State.The code, drafted under the Energy Conservation Act, 2001, seeks to reduce energy consumption of commercial buildings by 30 to 40 per cent through adopting various designs.Speaking after inaugurating a two-day Indian Sustainability Congress 2014 here, Mr. Shivakumar said the code would also be applicable to government buildings. He said the State Cabinet in its meeting here on Monday decided to adopt the code.

At a time when availability of power through conventional sources is becoming scarce, this move is likely to save considerable amount of energy in Karnataka, Mr. Shivakumar said. Also, the State has a vast potential of producing solar energy as it is sunny throughout the year in most parts of the State, he said.The department would bring out a comprehensive solar policy so as to encourage domestic solar energy production and to mitigate hardships, he said. 

The policy will also focus on addressing issues concerning requirement of land for setting up solar power producing plants. He urged academics and entrepreneurs to come out with innovative schemes for maximum utilisation of natural resources at a time when it is becoming scarce.

Enforcing agencies

 Ravi Kumar P., Additional Chief Secretary to Government (Energy Department), said the scope includes the envelope of the building and systems pertaining to heating, lighting, air-conditioning and water supply.While drafting the code, the Centre had given liberty to State governments to modify it to suit the geographical conditions of the region. Some States have already adopted the code. While the Public Works Department will enforce the code for government buildings, the Urban Development Department will do it for private buildings after suitably amending building bylaws, Mr. Ravi Kumar said. He said even without the code, many private and government buildings have adopted it and built green buildings. Now that the code is mandatory, all commercial buildings with more than 500 sq mt floor area have to follow the same, he said. Courtesy : The Hindu


* Tata's headquarters gets green gold rating!

The 91-year-old Bombay House, the headquarters of the $97 billion Tata Group, has become the country’s first heritage building to get the prestigious green rating from the Indian Green Building Council (IGBC).

The Bombay House has been awarded under IGBC’s green existing buildings gold (operations & maintenance) rating system, the over 140-year-old group said in a statement.

Built in 1923, the iconic Bombay House is situated in the Heritage Mile area of south Mumbai and is just a stone throw away from the RBI headquarters as well as swanky BSE Towers. It has been rated gold for implementing measurable strategies and solutions in five categories - site & facility management, water efficiency, energy efficiency, health & comfort and innovation, the statement added.

Some of the sustainability practices at the Bombay House recognised by the IGBC include its green policy, over 20 per cent energy savings as the building has achieved a 4-star rating from the Bureau of Energy Efficiency, over 50 per cent water savings, among others.

That apart, the IGBC has recognised its contribution to the maintenance of neighbouring areas like the nearby Esso Park with eco-friendly landscape practices and contributing towards the maintenance of the Horniman Circle Park etc.

The $97 billion Tata Group comprises over 100 operating companies, 32 of them publicly traded, in seven sectors - communications and IT, engineering, materials, services, energy, consumer products and chemicals.

The group is present in over 100 countries and reaches out to 150 countries. As much as 62.7 per cent of its $96.79 billion in FY13 came from overseas businesses. Tata companies employ over 5,40,000 worldwide.more..

What is a green building?

A green building is a holistic approach to design and construction that minimizes the building’s impact on the occupants, surroundings and the society. With the concept of green buildings gaining momentum among the developers, the Indian Green Building Council (IGBC) is expecting around 2 billion sq ft of green buildings by 2015. Currently, around 1745 buildings spread over 1.21 billion are registered with IGBC.    Green building or an eco-friendly building uses less water, optimises natural resources, saves energy, provides healthier space and generates less waste when compared with the conventional buildings. Courtesy: Manika Krishnan 




Green building materials are composed of renewable, rather than nonrenewable resources. Green materials are environmentally responsible because impacts are considered over the life of the product (Spiegel and Meadows, 1999)Depending upon project-specific goals, an assessment of green materials may involve an evaluation of one or more of the criteria listed below.

Materials are the stuff of economic life in our industrial world.  They include the resource inputs and the product outputs of industrial production.  How we handle them is a major determinant of real economic efficiency, and also has a major impact on our health and the health of the natural environment. 
        Although the primary focus of popular environmental awareness has been on energy, it is our relationship to materials that will probably have the most significance for green economic transformation and the establishment of sustainable societies.  Over the past decade or so, green thinking has increasingly recognized that minimal levels of sustainability depend on radical increases of resource-efficiency—in the industrialized countries, by a factor of ten.

We need to check the availability in india.

Building construction uses large quantities of natural resources; in fact, construction activities use 60 percent of the raw materials, other than food and fuel, used in the entire U.S. economy. And the nearly 170 million tons of annual building construction, renovation, and demolition derived wastes (commonly referred to as C&D materials) account for nearly 60% of the nation's non-industrial, non-hazardous solid waste generation.

Salvaging building materials and reusing them saves energy and reduces greenhouse gas emissions by minimizing the need to extract and process raw materials and ship new material long distances; it also reduces the economic and environmental impact from waste disposal (for example, greenhouse gases generated from waste decomposition, the need to build new landfills or the emission of air pollutants from waste incineration). Also, some salvaged building materials are rare and sought-after, such as marble mantles, antique fixtures, old growth hardwoods, wide-plank lumber and knot-free, fine-grain wood.


SOURCES Bldg Mtrls for Green Building.pdf




Any type of building has the potential to become a green or sustainable building, however every building type has different design and efficiency needs depending on its particular function. New buildings may be designed, built and operated to be green buildings. Existing building can also become green through remodeling, retrofitting and improved operations.



Green Buildings
The making of these eco-friendly buildings fundamentally involves:

  • Proper use of energy and environmental components: Firstly, the environmental components like air, water and natural resources are used in the most efficient way. Mainly renewable energy is used in such constructions. Energy sources, which can result to be harmful for the environment are avoided. Heat recovery ventilators and geothermal heat pumps are used to save energy.
  • Maintenance of the indoor of the buildings: Green buildings assure to be naturally ventilated and ventilating system is such that it does not harm the other neighboring buildings. Smoking areas are tried and constructed outside the building or are build in such a way that the smoke does not affect the environment of any other parts of the building. The use of the daylight is maximized. Biodegradable and natural friendly cleaning machineries are used.
  • Eco-Friendly materials used for construction: The engineers of these buildings try to ensure that the materials and resources used are environmental-friendly. From building materials to the interior furniture, everything is mostly made through recycling of products. 'Waste reduction plans' are carried out by the engineers and team.


There should be easy availability of public transport and conveniences so as to cut down energy consumption for transportation. A suitably selected site thus gets the benefit of mass transit. Also, rehabilitation of sites damaged by environmental contamination is a better option than any new piece of land where large amount of energy and resource is needed to make the land worthy of building on. Rehabilitation thus saves large amount of energy.    Already existing landscape, soil and natural features should be protected. For this reason, hard paving on the site should be avoided to preserve top soil and ease rain water harvesting. There should be minimum storm water runoff.   Material and Resources ·      Sustainable construction material are chosen keeping in mind various characteristics like zero or low toxicity, high recyclability, zero or low off gassing of harmful air emissions, durability, reused and recycled content, sustainably harvested material. ·      Dimensional planning and other material efficiency strategies are used to reduce the construction costs. Construction and demolition material can be reused and recycled for e.g. inert demolition material can be used as base course for landfills. Proper planning for managing materials through deconstruction, demolition and construction is done.  Efficient planning of utilities to minimize ·     Utilization of rapidly renewable materials, such as bamboo flooring, wool carpets, strawboard, cotton ball insulation (made from denim scrap), genuine linoleum flooring, or poplar oriented-strand board (OSB). Using rapid renewable helps reduce the use and depletion of finite raw material. ·      Use of materials that are available locally is preferred over materials that need to be brought from distant places. It saves transportation costs. Also, alternative materials that can be generated from waste with lesser energy is used over conventional building materials. For example, alternative materials for timber like MDF board, Mica Laminates and Veneers on composite boards should be used instead of natural timber. Industrial waste based bricks and blocks, aerated lightweight BPC concrete blocks, Phospho-Gypsum based blocks can be used for masonry structures. Fly ash, for bricks, outdoor paving and in concrete.

Buildings have an enormous impact on the environment, human health, and the economy. The successful adoption of green building strategies can maximize both the economic and environmental performance of buildings. Specific environmental, economic and social benefits are listed in Why Build Green?

Research continues to identify and clarify all of these benefits and costs of green building, and of how to achieve the greatest benefits at the lowest costs.


Environmental Benefits

  • Emissions Reduction. Pollutants released by fossil fuel fired electricity contribute to global climate change, cause air quality issues such as acid rain and smog, and pose risks to human health. 1 Green building techniques like solar powering, daylighting, and facilitation of public transport increase energy efficiency and reduce harmful emissions.
  • Water Conservation. Recycling rainwater and greywater for purposes like urinal flow and irrigation can preserve potable water and yield significant water savings.
  • Stormwater Management. Stormwater runoff can cause waterway erosion, flooding, and carry pollutants into water sources. Harvesting and redirecting stormwater, building surfaces with permeable materials, and using green roofs can control and utilize overflow.
  • Temperature Moderation. The heat retention properties of tall buildings and urban materials such as concrete and asphalt are the primary causes of urban heat island effect. These conditions may be offset by conscientious building design and site selection, as well as planting trees to accompany new developments.
  • Waste Reduction. Construction and demolition generates a huge portion of solid waste in the United States. Building deconstruction as an alternative to full-scale demolition results in massive decreases of waste production. 2

Economic Benefits

A common impression about green building is that the green premium is too expensive to be considered economically feasible. However, studies have shown that the costs of green buildings are not substantially higher than regular development projects. 3 Higher construction costs can generally be avoided by the inclusion of green design from the outset of the project. 4 Additionally, green buildings provide an assortment of economic advantages.

  • Energy and Water Savings. The resource efficiency provided by green design and technology leads to drastic reductions in operation costs that quickly recoup any additional project costs 5 and continue to offer dramatic long-term savings (see statistics). Money previously directed toward utility costs may be used for other purposes.
  • Increased Property Values. With energy costs on the rise, the low operating costs and easy maintenance of green buildings make for lower vacancy rates and higher property values.6
  • Decreased Infrastructure Strain. Efficient buildings exert less demand on the local power grid and water supply, stretching the capacity of local infrastructure.
  • Improved Employee Attendance. Green design emphasizes increased natural lighting and control of ventilation and temperature-attributes that improve employee health and prevent absences. 7 The U.S. Environmental Protection Agency reports major reductions in health care costs and work losses resulting from commonly recommended improvements to indoor environments (see statistics). 8
  • Increased Employee Productivity. Employee productivity has been positively correlated to indoor environmental conditions, and shows improvements where green principles have been applied (see statistics). 9
  • Sales Improvements. Studies show better sales in stores that utilize natural light. 10 Retailers are increasingly using daylighting in an effort to harvest the associated sales benefits.
  • Development of Local Talent Pool. With increased attention being paid to global climate change and the need for renewable energy sources, the field of building design and construction is moving toward sustainability as a permanent objective. As of July 2007, 23 states and more than 80 cities have legislated green standards for municipal buildings. Building green in Bloomington is an investment in the local economy, helping to foster a local talent pool: designers and builders experienced with green projects able to accommodate the growing market demand for sustainable development.

Social Benefits

  • Improved Health. Poor indoor environmental quality (IEQ) resulting from insufficient air circulation, poor lighting, mold build up, tempe


The energy used to heat and power our buildings leads to the consumption of large amounts of energy, mainly from burning fossil fuels - oil, natural gas and coal - which generate significant amounts of carbon dioxide (CO2), the most widespread greenhouse gas. Buildings in the U.S. contribute 38.1 percent of the nation's total carbon dioxide emissions.

Reducing the energy use and greenhouse gas emissions produced by buildings is therefore fundamental to the effort to slow the pace of global climate change. Buildings may be associated with the release of greenhouse gases in other ways, for example, construction and demolition debris that degrades in landfills may generate methane, and the extraction and manufacturing of building materials may also generate greenhouse gas emissions. More information is available on EPA's




Life-cycle assessment (LCA) is the science of measuring the environmental effects of a building "from cradle to grave," from the harvesting and extraction of the materials used to make the building to its ultimate disposal.

The ministry of external affairs' Jawaharlal Nehru Bhawan here on Tuesday became the first government building in the country to bag a Gold Rating Certificate for being energy efficient and sticking to green building norms.


The certificate was handed over to outgoing foreign secretary Ranjan Mathai.


Addressing the gathering, which included his successor Sujatha Singh, Mathai said the process to turn Jawaharlal Nehru Bhawan into a green building had been both an "interesting and challenging" task. SOURCE





Adding a major impetus to the Green Building Movement in India which is being spearheaded by CII's Indian Green Building Council (IGBC), the Jawaharlal Nehru Bhawan of the Ministry of External Affairs, has become the first government Office building in New Delhi to be awarded with IGBC's LEED India- New Construction (NC) Gold Rating.

Dr. Prem C Jain, Chairman, IGBC and Chandrajit Banerjee, Director General, CII presented the prestigious CII-IGBC Green Building Plaque and Certificate to Foreign Secretary Ranjan Mathai at a special programme organised at Jawaharlal Nehru Bhawan.

Mathai said that it is a matter of great pride that Jawaharlal Nehru Bhawan has been constructed as per Green building guidelines and this building is a perfect blend of India's ancient architectural concepts and modern technological innovations.

Green would soon become a way of life for the occupants of the Jawaharlal Nehru Bhawan, added Mathai.

Dr. Prem C Jain, Chairman, IGBC while expressing delight over this remarkable achievement underlined that, Jawaharlal Nehru Bhawan has scripted a new chapter in the annals of Indian green building movement.

This milestone will further enable other Government buildings to go the Green way and facilitate India emerge as one of the global leaders in green buildings, he added.

Dr Jain, while appreciating the commendable work done by the Central Public Works Department (CPWD) for the design and execution of Jawaharlal Nehru Bhawan said in days to come, CPWD has an important catalytic role in constructing all upcoming Government buildings in the country go the Green way.

Highlighting the steady growth of green buildings in country, Dr Jain said that today, India has over 2,110 IGBC registered green building projects amounting to over 1.54 Billion sq. ft of green building footprint with projects spread across the five climatic zones of the country, which has put India on the top 3 countries in world green building map. The vision of the Council is to 'enable sustainable built environment for all and facilitate India to be one of the global leaders in sustainable built environment by 2025', he informed.

Earlier, Tanmay Tathagat, Director, Environmental Design. Solutions (EDS) while making a brief presentation on the Jawaharlal Nehru Bhawan said that this building has been designed and constructed as per CII-IGBC Green Building guidelines. He added that some of the key green features of Jawaharlal Nehru Bhawan include:

* Energy savings of about 30%

* Water saving of more than 50%

* Courtyard integration for daylight, views and ventilation performance

* Integration of roof gardens- reflective roof and grass pavers

* Building Management System- integration of MEP Systems for Systems Control

* Controllability of lighting and HVAC for 90% of the building occupants

* Extensive use of old furniture 




 While green building as a concept isn’t new to Amdavadis, takers’ opinions vary. A study conducted by a student at the Centre for Environmental Planning and Technology (Cept) University reveals that awareness level about green buildings and willingness to pay more for construction of one is higher in city’s western parts than in the eastern side. 

In fact, response from the buyers suggests that awareness in eastern Ahmedabad is very low, compared to areas like Ashram Road, SG Road and Prahladnagar, where buyers showed greater willingness to bear the extra cost for a green building.  

Due to corporate culture, price is less important but soft benefits like environmental friendliness, waste recycling, water conservation and the image built by the green building, according to the study. 

The study titled ‘Green Building: Buyer’s point of view’, conducted by Tejas Jasani, a student of faculty of sustainable environment and climate change at Cept, also reveals that people in eastern areas are willing to pay 4-6% higher amount for a green building. 

However, in contrast, people in west Ahmedabad showed willingness to shell out 5-7% more on SG highway and even 8% in areas like Prahladnagar.

The study states that “SG highway respondents from Prahladnagar are ready to pay 8% higher for 30-40% reduction (in emissions). Respondents are okay with five years’ payback time so proposed building can be up to LEED (Leadership in Energy and Environmental Design) -PLATINUM rating level for green buildings. 

The study aimed at finding criteria considered by different rating systems for a green building in India and analyse the initial cost and future benefits of green buildings against conventional ones. 

It also wanted to study all variants considered by a buyer before buying property and to find desired cost and benefit ratio and payback time for green buildings.SOURCE

Recognising the project's efforts towards reducing energy and resource footprint, The Association for Development and Research for Sustainable Habitats (ADaRSH) awarded the coveted GRIHA-Green Rating for Integrated Habitat Assessment-certificate to the Indian Railways' Secunderabad-based Rail NirmanNilayam project in New Delhi today.


ADaRSH is a society established by The Energy and Resources Institute (TERI) with support from and under guidance of the Ministry of New and Renewable Energy, Government of India to implement GRIHA, the national rating system for green buildings.


Constructed by the South Central Railways at Secunderabad, the Rail NirmanNilayam project is the first GRIHA-registered project covered under the Ministry of New and Renewable Energy's incentive scheme to receive the provisional GRIHA rating. It is also the first project of the Indian Railways to be registered for GRIHA compliance.


Dr. R.K. Pachauri, Director General, TERIand President, ADaRSH and Ms. MiliMajumdar, Director, Sustainable Habitat, TERIand Secretary ADaRSH presented the prestigious GRIHA rating to Mr. S.K. Sharma,Chief Administrative Officer, South Central Railways at the Institute's India headquarters.


Congratulating the Rail NirmanNilayam team, Dr. Pachauri said, "There is a huge scope to have green and eco-friendly buildings in the Indian Railways. The need of the hour is to create a movement across the Indian Railways to ensure upcoming buildings have a set benchmark to follow in terms of energy efficiency."


Completed in 2011-2012, the Rail NirmanNilayam project is spread over an area of 7800 square metres, with the built up area being around 4405 square metres. The complex has achieved 36.5% reduction in energy consumption as compared to the GRIHA benchmark by adopting several energy efficiency measures such as use of high performance glass, shading systems, efficient lighting and space conditioning systems, controls for lighting etc.

What is IGBC certification and how is it obtained?


This unique rating programme for Indian residential sector has been developed in accordance with well-defined principles of environmental preservation and increased energy efficiency.


Contrary to common belief, IGBC certification is not a Draconian system which is next to impossible to obtain. However, it does demand a highly disciplined development approach that is aimed towards delivering environmentally sustainable projects.


To get IGBC certification, a developer of a multi-storey residential project needs to meet certain mandatory requirements and obtain a certain amount of 'green' credits. Projects can qualify for precertification once the developers in question have incorporated IGBC requirements in the project’s design and submitted the relevant documents to IGBC.


The final IGBC certification is awarded once the project is complete. The process is fairly simple and straightforward, but it is also very thorough. When a developer registers his project under the IGBC Green Homes Rating System, he is making a commitment to ensure that the project will conform to all IGBC requirements.  source

* World’s largest LEED Platinum rated hotel , in Chennai

ITC Hotels has secured a LEED Platinum rating, by India Green Building Council (IGBC), for its soon-to-be unveiled, 600-room premium luxury hotel in Chennai; the ITC Grand Chola. This has made ITC Grand Chola the world’s largest LEED Platinum rated hotel in the new construction category. more



* India is witnessing a tremendous growth in infrastructural development. The construction industry reflects one of the largest economic activities of the country. As the sector is growing rapidly, preserving the environment poses many challenges and at the same time presents wonderful opportunities for various stakeholders.



The demand for energy, water and materials for construction has been growing enormously over the years and the need has arisen to address the minimization of natural resources for the building construction and their associated impact on environment. Building sector accounts for 30-40 percent of global Green House Gas emissions.

The construction sector therefore needs to play a responsible role towards preservation of the fragile environment. In this regard, green buildings can play a catalytic role in addressing environmental issues and concerns.

The major benefits of green buildings include energy savings to the tune of 40-50 percent and water savings of about 20-30 percent, intangible benefits which includes: enhanced ventilation, better views and day lighting that significantly improve the productivity of the occupants, green corporate image and it also demonstrates the company's commitment to environmental protection

Green Buildings movement in India, with the support of all stakeholders is being spearheaded forward by the Indian Green Building Council (IGBC) of the Confederation of Indian Industry (CII). The council is represented by stakeholders across the board of the Indian construction industry comprising of the government, corporate, nodal agencies, architects, designers, institutions, builders & developers, product manufacturers, suppliers, facility managers among other sector players.

IGBC, with support from all stakeholders works with the government of Maharashtra in developing 'environment guidelines' for Area Development Projects in the state. With a modest beginning of 20,000 sq ft in the year 2003, green built-up area in the country, today (as on July 2012), 1,707 green buildings projects with a built- up area of over 1.20 billion sq. ft are registered with the IGBC, out of which 267 green building projects are certified and fully functional in India. These include offices, factories, hospitals, hotels, it parks, airports, banks, residential spaces, SEZ's, townships among others.

Mumbai itself has about 250 buildings registered with IGBC, which are at various stages of construction. Mumbai ranks second in the country with 36 rated operational green buildings.


One of the biggest reasons why green buildings are now widely accepted by the cross-section of the society is the fact that green buildings make good business sense and are financially very attractive. The construction costs of a green building would be 5-8 percent higher for a Platinum building than a conventional building, the incremental cost gets paid back within 3-4 years with substantial reduction in operational costs.

For instance, the declining initial incremental cost over years of Kalpataru Square in Andheri East locality of Mumbai, which was Platinum-certified in 2008, measuring 3, 27, 000 sq ft has been 2 percent. Few of the green buildings which have been in operation for 5 years have been monitored for operational savings.

Kohinoor Hospital in Kurla with a built up area of 21,137 sq ft has seen a reduction of 40 percent. By 2012, IGBC expects the number of green building projects registered in India to reach 2,000. This in turn will catalyze more business opportunities. It is estimated that the market potential in India for green building products and technologies would be about US$120 Billion by 2015.

Buildings have always been one of the most secure investments, but did you know that buildings could be made moreprofitable and healthy places to live-in and work too? Yes! All you need to do is – ‘Go Green’.What is a green building?A Green building uses less energy, water and natural resources, creates less waste and is healthier for the people living in itcompared to a conventional building.A green building results in tremendous benefits, tangible & intangible.For example, these buildings offer 40-50 % energy savings, 20-30% water savings besides productivity gains and healthyenvironment.The IGBC (Indian Green Building Council) Green Building Design guidelines revolve around the 5 elements of nature viz. ,Site, Water, Energy, Materials and Indoor Air Quality. The rating programmes adopts a holistic approach towards buildingdesign, construction and operationWhat is a green building product?A green building product usually has one or more of the following characteristics:Contains less embodied energy, manufactured with renewable materials, manufactured with renewable energy, uses lessamount of water and material resources in its manufacture, releases minimal or no toxic waste during its use, is long lasting,easy to maintain, easy to recycle, easy to dispose off, saves energy, water & other natural resources during its use andresults in a healthier environment compared to common alternatives.How to choose a green building product?Products that are locally made with local resources including renewable energy use, recycling of waste and minimizationof waste during manufacture could be the broad screening criteria. Further, 3rd party certifications might exist for certainproduct segments like CRI (Carpet and Rug Institute) certification for carpets, FSC (Forest Stewardship Council) certificationfor virgin wood based applications, green seal certification for house keeping chemicals and programmes, green guardcertification for furniture etc. The green building certification guidelines pertaining to materials and equipment helpchoosing the best product for a particular project.How do green building materials & equipment figure in the building certification process?Selecting a certain brand or certain quantity of green building materials/equipment in isolation does not ensure a specificlevel of rating (gold / platinum etc. ) Neither are points assigned to a particular product / technology. Green Building is allabout integrated design where the materials and equipment are selected based on the overall design objectives of theproject and green guidelines of the rating system. While green materials and products contribute to the greenness of theproject, their overall effect on the rating depends on the several green attributes. Credit points for materials are evaluatedbased on the percentage of that component cost with respect to the overall cost of the project.About CII - Sohrabji Godrej Green Business Centre

SURAT: When Surat Builders Association (SBA) organized a property show in March, nearly 25 developers promised to come up with 51 green buildings, all residential, in the city.

Nearly 30 buildings are under construction, but the developers are finding it difficult to sell them as buyers are not willing to pay additional cost incurred due to specific green building provisions. As result, the construction of green buildings has slowed down in the city.


Velji Sheta, president of Surat Builders Association, said, " We incur 12-15 per cent more expenses in green buildings. People are reluctant to buy in such schesms but now the awareness is gradually increasing."

Green buildings concept assumes significance considering that Surat has city has just 8.4 per cent green cover, lowest among the big cities of western India.

"There is an additional cost factor involved in these projects and at times buyers are not willing to part with this hiked charges," said Tarun Rawal, who is planning green residential schemes in Parvat Patia and Vesu. "Yes, we know we need to develop green buildings and townships for the future of the sustainable city. But first we need to educate people about such buildings, its benefits and advantages in the long run," added Rawal, who is the former president of SBA.

If the houses have a green roof, temperatures can be brought down by at least three degrees Celsius. This was the view expressed by the experts of Indian Green Building Council (IGBC) in a seminar on - Green and Sustainable City Development organized by South Gujarat Chamber and Commerce and Industry. (SGon Saturday.


"Unless we have green building concept in our constructions, it will be very difficult to sustain the high economic growth engine of the city," said Ankur Sanghavi, an architect from a university in Arizona, US and member of Indian Green building Council (IGBC).  source  2/8/12

Weeks of planning that began with the conception of a workshop on ‘trends in green buildings’, followed by few interactive sessions with students of architecture schools and colleges, climaxed last Wednesday with a soulful pledge by a predominantly young audience at the conclusion of a day-long workshop at The Raintree Hotel in Chennai.

“We will talk Green and think Green,” said the budding architects, as Prof. S F Rajaratnam, Chairman, Indian Institute of Architects, Tamil Nadu Chapter, administered the pledge to the nearly hundred strong delegates at the ‘Trends in Green Buildings’ workshop organized by The Weekend Leader.

The Workshop was an eye opener to the students (Photos: Blesson Andrews)

The Workshop was an eye opener to the students, who got an opportunity to listen to some of the leading green architects, and renewable energy experts in the country.

Many have vowed to become ambassadors of green buildings.

Samyuktha from Rajalakshmi School of Architecture, who said she found the workshop inspiring and informative, added, “I plan to make a power point presentation in my class based on the topics that were discussed for the benefit of those who could not participate in the workshop.”

B P Sabarish, a third year student from SRM School of Architecture, Ramapuram Campus, said, “Though green building concept is incorporated in our syllabus, the sessions provided more implementable information," he said.

Delivering the keynote address at the workshop, T Chitty Babu, Secretary, Confederation of Real Estate Developers Association of India, National, warned against the excesses in the name of development.

Emphasizing that there was no way forward except to go for green buildings, he said the cost of construction and maintenance would come down by incorporating green building techniques.

Student delegates at the workshop

Chitra Vishwanath, Principal Architect, Biome Environmental Solutions, Deepak Thakur, Corporate Head, Solar Business Group, Thermax India, Deepa Satiyaram, Founding Director, En3, Suresh Krishn, Managing Director, Isha Homes, Vikshut Mundkur, Manager – Projects, Solar Electric Light Company India, and Vineeta Badawe, Resident Director, V V Architects, spoke at the workshop.

C N Raghavendran, Chairman, LEED India and CII-Indian Green Building Council - Chennai Chapter, and partner of CRN, delivered the valedictory address.

Leading the resource group at the workshop were senior consultants on urban planning, G Dattatri and M G Devasahayam of NGO SUSTAIN, and Prof. J Subramanian, Executive Director of STUP group of Companies.

Senior journalist Sam Rajappa delivered the vote of thanks.

The Weekend Leader plans to take the Green Buildings Movement to the masses and tier two cities from its present urban, elitist orientation.

Bayer's new office building, Greater Noida, highest LEED rated in India



In a move that will put India on the green building map, Bayer’s new 10,000 square-foot office building outside new Delhi has achieved LEED Platinum with an impressive 64 out of 69 possible points, officially making it the highest-rated LEED building in the world.

As another addition to the company’s EcoCommercial Build Program, the complex was built with efficiency and sustainability in mind. All power for the building is generated on site via photovoltaic cells. To make net-zero consumption achievable, the offices are insulated with polyurethane foam boards which lock out solar heat and reduces cooling needs by over 70 percent.



Grey water systems, locally-sourced and recyclable materials, double-glazed windows and intelligent lighting and climate control systems also contributed to the building’s ultra-green status, with day-lighting and water harvesting components gaining points as well. The building is designed to function up to eight hours off-power without any impact on the infrastructure.

“The Platinum Award is a clear indication that the concept of ecologically sustainable building can be achieved with the right materials, regardless of whether in the developed world or in an emerging market,” said Thomas Roemer, head of the construction & building industry platform at Bayer MaterialScience. As the world’s highest-rated LEED project, Bayer’s new offices will challenge builders the world over to incorporate sustainable design into new projects. source



70 per cent of the building stock that would be there in 2030 is yet to be built in the country.


Either we build energy and water saving green buildings or we perish.
That is the latest warning from research and advocacy body Centre for Science and Environment on the disastrous fallout of the aggressive building construction that is underway.

The CSE says that both residential and commercial buildings were going to increase several fold in the coming decade, as nearly 70 per cent of the building stock that would be there in 2030 was yet to be built in the country.
This will have enormous impact on the quality of urban space, water and energy resources in cities and waste generation.
“It is shocking that Indian cities are extremely ill prepared to address the environmental fallouts of the aggressive building construction that is underway. Unless guided with right principles for location choices, architectural design, appropriate choices of building material and operational management, the building sector can make cities unliveable.”
According to CSE study, buildings were responsible for 40 per cent of the energy use, 30 per cent of the raw material use, 20 per cent of water use, and 20 per cent of land use in cities. At the same time, they cause 40 per cent of the carbon emissions, 30 per cent of solid waste generation, and 20 per cent of water effluents.
“Despite being a major resource predator, the building construction sector is poorly regulated. Buildings cannot be treated as a low-impact sector,” says Anumita Roychowdhury of CSE.

There is potential for resource savings in buildings if appropriate policies are in place. With more efficient lighting, ventilation, air conditioning, refrigeration and architectural design, it is possible to save 30-70 per cent of energy.

The 2010 McKinsey estimates confirm that the national power demand can be reduced by as much as 25 per cent in 2030 by improving energy efficiency of buildings and operations. The Bureau of Energy Efficiency has also stated that even existing buildings have the potential to save 30-50 per cent of energy.

Similarly, substantial water savings is possible. Only by improving the water efficiency of the water fixtures the water demand can be reduced by more than 30 per cent.

The problem is the sheer lack of information, say CSE researchers. There is barely any information and data on buildings in the public domain. Even in cases where green rating systems have been promoted with government back-up and incentives, there is no record of the actual performance of buildings and the nature of resource efficiency measures applied. source 29/6/12

Green buildings gain momentum in India

Noida near Delhi is one of the nodes of the green building movement. The builder 3C was an early mover. 3C built what was the country's largest green apartment complex. Called Lotus Boulevard, this was planned as a 500-unit complex, but all of it was immediately sold out and the enclave ended with 3000 units. The success of this project and some incentives by the Uttar Pradesh government have led to a rush of green building development in Noida. None of them is probably more impressive than the Bayer ECB Centre of Excellence. It claims to have bagged highest number of points in its LEED certification process, making it the greenest LEED certified building in the world.

The building is the R&D centre of Bayer Material Science. It is inside a larger campus of Bayer, with buildings that are attached to it electrically. The R&D centre, which has solar panels, draws power from the other building at night but gives it back during the day. Last year it gave back more than it took, thus making it a net-positive energy building, but Bayer claims it to be only a net-zero energy building. "We have ensured that we get segment-wise energy consumption data from each part of the building," says Ram Sai Yelaminchili, head of the centre. "That helps us monitor and control energy consumption efficiently." 


The R&D centre becomes a net zero energy building not by generating a lot of electricity but by incorporating features that are now becoming common in many platinum-rated green buildings in the country. It uses natural light during the day, and through good design - that uses a mixture of wall and glass - and orientation ensure that light gets through without heat. High quality foams insulate the building, making sure that heat is not let in during summer and not let out during winter. "It does not need very high technology to make a building energy efficient," says Jain. But high technology helps sometimes, and ingenuity helps even more than technology.  ake the Beary Golden Research Triangle (BGRT) in Bangalore, a name inspired by both the triangular nature of the land and the Research Triangle in North Carolina. This building, when ready for occupation in four months, would be let out mostly to R&D units of companies. Two major multinational companies have taken up space for global R&D centres. BGRT has been pre-certified as a platinum-rated building - the final certification is usually given after the construction is complete and occupants have moved in - and it has design features that will become common in many large buildings across the country.
Visitors would note from a distance the unusual alignment of the building. It slopes on one side, thus keeping out direct sunlight till late afternoon. The glazing lets light through but not heat. The air-conditioning is extremely efficient; the outgoing air partly cools the incoming air without mixing, and water cools it further and minimizes the energy consumption. It is designed to use air from outside for cooling when outside temperature is below a certain level, a feature that is very useful in the salubrious climate of Bangalore. Says Syed Mohammed Beary, chairman of the Beary Group: "This is the first time a private developer has built a platinum-certified commercial R&D space."

Such features are part of many buildings certified by LEED or Griha. Technology comes in handy too, especially in large corporate offices. You could have the most energy-efficient lighting in the world, but leaving the lights on all the time defeats the original purpose. In the year 2008, a study commissioned by the US non-profit New Buildings Institute showed that some green buildings do not save energy as much as planned. Many green buildings now avoid this problem by becoming smart. "Smart technologies are necessary to minimise energy consumption," says Sandeep Dave, principal of Booz & Company, who studies smart buildings in the country. source 29/6/12

It is estimated that 40% of US power consumption is attributed to buildings, and companies large and small are focusing on ways to reduce wasted energy in the places we live and work. With technological advances come new options for streamlining energy efficiency programs.

"You have to look at a building as an organism that needs to be monitored consistently because conditions change – like weather or occupancy. A building is a dynamic entity, you can't just build it and walk away," Dave Bartlett, Vice President of IBM Smart Buildings recently told AOL Energy.

IBM's smart building initiative was created because so many building systems now send out digital information, from things like lighting systems, CO2 sensors, security systems that monitor which doors and windows are open when, and even badge readers that can illustrate which portions of a building are occupied most and least often and at what times.

IBM is able to capture this data, run analytics on it and design optimization solutions that have been very effective in terms of saving energy and money, said Bartlett. This approach also allows companies to look across portfolios of buildings to see which are using energy efficiently, which are not - and why. more  1/8/12

• Energy cost savings, enhanced brand or public image and increasing energy security led as drivers for energy efficiency action. 

• one approach to demonstrating interest in enhanced brand or public image may be the pursuit of green buildings. in india, 73% of respondents indicated they had at least one certified green building.  fifty-six  percent planned to pursue green certification in new buildings, and 54% percent in existing buildings. 

• indian respondents were particularly interested in finding ways in which a building’s green attributes could be reflected in the market. When asked which energy policy would have the greatest impact on improving energy efficiency in buildings, 21% said the adoption of green appraisal standards that value efficiency improvements would be a top priority, along with low-interest financing for energy upgrades, and stricter building codes and equipment standards.

*Sustainable architecture in India

“If one accepts the simple proposition that Nature is the arena of life and that a modicum of knowledge of her process is indispensable for survival and rather more for existence, health and delight, it is amazing that how many apparently difficult problems present a ready solution.”

The key to architectural sustainability is to work with, rather than against Nature; to be sensitive so that we do not damage the natural systems. Architectural sustainability mirrors the view that it is necessary to position human activities as a non-damaging part of the ongoing ecological landscape, with a belief that ‘nature knows best’. source 24/6/12

“As a part of the challenge, students were required to create a design of a new building complex that is commercially feasible in an Indian city or rural area and that incorporates the modern water technologies needed to meet the future water crisis,” said Dr Gopichand Katragadda - General Manager, India Energy Operations for GE Energy Infrastructure, source


Like Delhi, Mumbai, Pune and other big cities, Ranchi will also get green buildings now.


Central Institute of Psychiatry Kanke, National Law University (constructed last year), Indian Institute of Management Ranchi, which is under construction, and Central University of Jharkhand, are among the first buildings to have subscribed to the idea. This concept will lead to less energy consumption and will provide more comfort to the occupants.

Consultant of the Association for Development and Research of Sustainable Habitats (ADaRSH) R S Prasad said, "It is extraordinary that Ranchi has shown interest in developing green and eco-friendly habitats. Green and sustainable buildings are required for healthy living in Jharkhand."

Founded jointly by The Energy and Resources Institute, New Delhi and the Union ministry of new and renewable energy, ADaRSH promotes green building concepts in India through Green Rating for Integrated Habitat Assessment (GRIHA).

"There are over 200 GRIHA registered buildings in India currently," said Prasad. GRIHA is India's national ratings system for green buildings.


* A common perception about eco-friendly homes is that they are expensive to build .


Indrajit Kembhavi, whose firm constructed the Police Bhavan in Gulbarga, one of the first gold LEED rated buildings in India believes that “the initial investment may be higher but in the long run these buildings are definitely cheaper to maintain.” According to Chitra Vishwanath, a well-known architect, eco-friendly houses are much cheaper when it comes to maintenance.


In fact, she says there is no reason why they should not be cheaper to build as well.


She points out that a study conducted by the World Business Council for Sustainable Development, showed the true cost difference between green and conventional buildings to be five per cent.

The green building concept in India was introduced with the southern regional centre of The Energy and Resources Institute (TERI). more 14 may 12

Energy Efficient LightingLighting in a home is generally responsible for 20% of the electricity bill.Efficient lighting reduces energy consumption, thereby, saving energy and money, without compromising on the quality of light. Lighting improvements are the surest way of cutting energy bills. Using new lighting technologiescan reduce energy use in the house by 50% to 75%. Lighting controls offer further energy savings by reducing the amount of time that lights are on without being used.

Indoor lightingUse fluorescent tubelights and energyefficient CFLs (compact fluorescent lights) in fixtures at home for high-quality and high-efficiency lighting. Fluorescent lampsare much more efficient than incandescent (standard) bulbs and last up to six times longer.  Although fluorescent and compact fluorescent lamps cost a bit more thani n c a n d e s c e nt   b u l b s ,   t h e y   p a y   f o r  t h e m s e l ve s   b y   s a v i n g   e n e r g y   o ve r  their lifetime.A 15W CFL can replace a 60 W incandescent bulb and a 20W CFL can replace 100W bulb. The average cost of a CFL is Rs 100, and theexcess investment is easily paid back in ayear’s time. A 36 W triphosphor tubelight, provides 32% more light than an ordinary tubelight and can be used in larger spaces. T5 tubelights are good replacements for ordinary tubelights. They save about 40% energy and last twice as long as ordinary tubelights.  The cost of a T5 tubelight varies between Rs 450 and Rs 500.

Outdoor LightingMany  homeowner s  use outdoor   l ight ing  for  d e c o ra t i o n   o r   s e c u r i t y.  Consider PV-powered lights for areas that are not close to an existing power supply line. Solar outdoor lights also come as stand-alone fixtures. An 11 W CFL, with a 74 W photovoltaic module and a 12  V/75 AH battery, costs Rs 22 000–24 000. When fully charged, the battery can power a light from dusk to dawn..

Earth Air tunnel

At a depth of 4 m below ground, the earth’s temperature remains more or less constant throughout the year. This temperature is nearly equal to average temperature of the place. For example in Delhi, the temperature in summer may go up to 45 °C during summer and fall to 4 °C during winter, but at a depth of 4 m below ground the temperature remains nearly 26 °C round the year, which is average temperature of Delhi. 
The earth air tunnel takes advantage of this phenomenon. Concrete hume pipes are laid at a depth of 4 m below ground and are surrounded by earth. The earth acts as a heat exchanger for air that is passed through this tunnel. Hot summer air is passed through this buried pipe, and as it passes through, there is an exchange of heat between the air and the surrounding earth. Hence, during the summer, the air gets cooled and during winter it gets heated. It works in a similar manner during the winter, absorbing earth’s heat and releasing it into the structure. Tunnel air can be supplied to a house for cooling during summers and heating during winter.I am sure this is not being followed in many places.This can help heat and cool an energy efficient house.

Solar ChimneySolar chimneys are tall, hollow structures that are preferably located on the south/south-west portion of a building. These chimneys can help ventilate rooms and are ideal for hot climatic zones. They should, preferably, be dark in colour with lightweight construction (for instance, ferrocement). Spaces within a building have vents opening into this chimney. The chimney heats up during summer days and the air inside the chimney rises creating a low-pressure zone. The air from the rooms of the house then replaces the escaping chimney air creating a low-pressure zone inside your home. This makes way for outside air to enter the home naturally and cool it

Roof treatment Some simple roof treatments, other than roof insulation, for reducing the summer heat gain in buildings, are as follows.¡ White washing the roof before the onset of the summer.¡ Spraying water on the roof.  Sprinkling water at regular intervals can reduce heat gain through roof.¡ Using shining and reflecting material for the rooftop.
Evaporative coolingWhen water stored in a water b o d y   e v a p o ra te s   i n to   t h e  surrounding air, it lowers the a m b i e n t   te m p e r a t u re.   T h i s  p h e n o m e n o n   i s   kn o w n   a s  e v a p o ra t i ve   c o o l i n g.   T h e  presence of a water body such as a pond, lake or sea near the building or even a fountain in the c o u rt y a r d   c a n   p ro v i d e   t h e  c o o l i n g   e f fe c t .   T h e   m o s t  commonly used system is a desert cooler,

A PV system can be incorporated in a building as part of the building's structure. In new buildings, PV systems can be built-in at the design and construction stage. They can be retrofitted on existing buildings as well.  Photovoltaics can be integrated in every possible structure—from bus shelters to high-rise buildings. They can also be used as landscaping elements.Incorporating PV in a building results in the following value additions.¡ Generating electricity at the point of demand without any extra use of land area¡ Reducing the cooling load of the building, as it also acts like a shading element¡ Replacing building construction material, such as glazing elements, depending on the building designIn building integrated PV systems, PV modules are used as part of the building envelope. PV systems can be incorporated in a building in three basic ways.

TIPS for saving Energy
Passive design¡ Use light colours to paint the interior of home for effective day lighting.¡ Incorporate solar passive designs in buildings at the time of construction.¡ In summers, draw curtains over windows facing south, west, and south-west or use sun films. ¡ Install double pane windows—heat escapes through a single glass pane almost 14 times faster than through a well-insulated wall.¡ Control heat, air, and moisture leakage by sealing windows and doors with natural materials.  ¡ Use reflective tiles or insulation on the roof to keep the interior cool.
Lighting¡ Switch off lights and fans when there is nobody in the room.¡ CFLs use 75% less electricity and offer similar amount of light as incandescent bulbs. If you replace 25% of the lights in high-use areas with CFLs, you can save up to 50% in lighting energy bills. ¡ Electronic ballasts can reduce power consumption by 20%.  You can cut consumption by 10%–50% with slim tube lights that are star-rated by BEE.¡ Use artificial lighting only when there is inadequate natural light in a space. ¡ Ensure that the type of lamp used in a space complements the tasks being performed in that space. This is commonly referred to as task lighting. For instance, do not use two wall-mounted bulbs where a single table lamp will suffice. 
¡ Use dimmer switches. They allow lighting levels to be adjusted according to the occasion or task and reduce the energy consumption of the lamp.¡ Use outdoor lights with timers or photocells so that they turn off automatically in daylight. ¡ Replace electromagnetic (copper) ballasts (chokes) with electronic ballasts. ¡ Don't replace tube lights with CFLs. A CFL is a point source, that is, it emits light from a single point, whereas a tube light is a line source and emits light over a larger linear spread. ¡ Don't use dark-coloured surfaces in workrooms. These reduce the reflected light levels and increase the number of lamps required to illuminate the space.¡ Avoid switching lights on and off frequently. This affects the lifespan of the lamps.

Electronic devices and appliances¡ Look for BEE-star labels on electrical appliances.¡ Use electronic devices with occupancy sensors which switch on or off automatically by sensing if the room is occupied.¡ Switch to evaporative coolers from air conditioners during hot/dry summer months.  ¡ Buy split ACs instead of window ACs.  They cost more, but they are more energy efficient and consume lesser electricity.¡ Do not install AC units on walls that are exposed to direct sunlight through a major part of the day during summers. In other words, avoid installing the AC on the west and south walls. ¡ Do not apply dark colours on the external surfaces (roof and walls) of the house. Dark colours absorb more heat than light colours, leading to increased use of the AC.¡ Do not expose the condenser (the part that faces outside) of split units on the terrace/roof to direct sunlight.Electronic devices and appliancesEnsure that walls do not surround the AC unit on all sides. The condenser of the unit must have enough space around it for air to circulate and to help the refrigerant dissipate its heat easily. ¡ When using ACs avoid overcooling of the room to a degree where quilts need to be used.¡ An easy way to cut down on the energy required by an AC is to set the thermostat at the highest possible point, and turn on the ceiling fan. This shall create air movement, circulate the cooled air more effectively, and help your sweat to evaporate easily without greatly increasing electricity use.¡ With each degree that the temperature setting of an AC above °22  C, 3% – 5% less energy is used. Set the temperature of the AC °at 25  C for the most comfort at the least cost.¡ Clean an AC unit’s filter periodically to enable efficient airflow and cooling. ¡ Do not use remote controls for switching off televisions and ACs. Switching them off from the mains saves electricity.¡ Switch off electrical appliances when not in use.  Low power gadgets such as chargers, adaptors, inverters, televisions, and so on consume substantial power even in the standby mode. ¡ If computers must be left on, turn off the monitors; monitors alone use more than half the system’s energy. Setting computers, monitors, and copiers to ‘sleep’ mode when not in use helps cut energy costs by about 40%.¡ Activate and standardize ‘power down’ on new and existing PCs. ¡ Purchase flat-screen LCD monitors. ¡ Do not use screensavers when computer monitors are not active. Let them switch to the sleep mode or turn them off instead.¡ Allow enough space for air circulation around refrigerators.¡ Avoid opening refrigerator doors frequently as it leads to energy loss.¡ Allow hot food items to cool to room temperature before putting them in refrigerators.


* National conference on green buildings 

The issues raised at this conference reiterated the fact that buildings today consume a substantial portion of water, energy, wood and other resources used in an economy. It is acknolwedged that they are responsible for about 40% of energy consumption and carbon emission globally. No wonder the call is getting more vocal for buildings to go green. But the misconception that green buildings are lot more expensive to make than conventional buildings has severely hindered the translation of this call into actual practice. 

Another issue that came up strongly was that with 23 big cities in the country, by 2050 two-thirds of the population will be living in urban areas. An increasing rate of industrialisation and infrastructure development is combining with population growth and urbanisation to exert enormous pressures on the urban landscape. And in such a scenario, the urgency to employ methods and techniques to save the environment from potential harm could not be overstated.

“India needs to design and construct more green buildings for bridging the growing gap between energy demand and supply, and in order to sustain the steady migration of people from rural to urban areas,” said special secretary at the Ministry of Environment and Forests J M Mauskar.more

What is arbortecture? Gorgeous, truly green building, that's what.

Define 'sustainable construction'? What are the aspects that decide the 'sustainability' of an urban project? Sustainable construction, also generally known as 'green building', is design and construction practices that significantly reduce or eliminate the negative impact of buildings on the environment and occupants in five broad areas: site, water, energy and atmosphere, materials and resources, and environmental air quality. 

For urban areas, there would be greater emphasis given to a building's connectivity in terms of existing infrastructure, amenities and mass transit. Also, for urban areas, with scarcity of land, buildings should consider higher density to maintain light, air and green open space, and avoid contributing to light pollution and urban heat island effect. 

What are the most common drivers leading to green projects? 
Cost of energy: Green building can typically save up to 30 per cent of energy consumption over conventional buildings, and payback period on most green investments are three to five years. 

Regulatory benefits/incentives: Many national, state and local governments around the world offer incentives for developers to build green. In some cases it may be energy or water saving mandates set in the building code which drive the green features of the project. Many governments also offer incentives in terms of additional FAR, lower taxes and access to grants and technologies to incentivise developers. 

Brand value: Many 'Fortune 500' companies and developers have a sustainability focus in their missions and CSR policies and choose to build green. By building green they are "walking the walk" and communicating their core values to their customers. 

What are the responsibilities of an architect while ensuring sustainable construction? 
The best green buildings begin on the architect's drawing table. Architects need to first consider the best climate-responsive design strategies for the site. Costneutral strategies like natural day lighting and ventilation, and passive cooling need to be optimised first, and then active mechanical and lighting systems should be appropriately and efficiently designed. 

Throughout the construction process the architect should ensure that green specifications for equipment and materials are implemented on site, that measurement and verification of building performance aligns with the design intent. 

What are the sustainable practices used in the design and construction phases? 
Design phase  

  • Optimised landscape design using xeriscaping and indigenous and adapted plant species  
  • Storm water management to aim for zero discharge from the site  
  • Green and high-SRI hardscaping design and high albedo roof design to reduce heat island effect  
  • Light pollution reduction selection of interior, exterior and landscape lighting  
  • Innovative wastewater use (wastewater treatment and reuse)  
  • Water-reducing, low-flow plumbing fixtures, with dual grey-water plumbing system  
  • Storm water harvesting with storage and detention for reuse or recharge  
  • Double skin masonry walls with air gap insulation with masonry blocks and bricks with low-U value and low embodied energy  
  • Double insulated glass windows, with low-e and thermal breaks  
  • Passive design strategies such as trombe walls, evaporative cooling, natural air convection, to reduce mechanical energy demand  
  • Low consumption lighting design — e.g. T-5 CFLs and LEDs  
  • Lighting controls - e.g. occupancy sensors and demand control task lighting  
  • Efficient ACMV systems (most important aspect of service design to obtain high energy use reduction)  
  • Solar hot water heating  
  • Assessment for solar PV for common areas and parking/landscape lighting

Construction phase 

  • Use of regional materials  
  • Use of recycled materials  
  • Construction waste management to target 90 per cent diversion from landfill for innovation point  
  • Certified wood  
  • Indoor air performance to ASHRAE 90.1 2007 and ASHRAE 55/LEED v. 3 2009 standards  
  • Outdoor air delivery monitoring and demand control, CO2 sensors in densely occupied spaces  
  • Use of low emitting/low VOC paints, sealants, flooring and agrifibre boards  
  • Thermal controls and design to ASHRAE 55 thermal comfort requirements  
  • Maximise design to achieve minimum daylight factor of 2 per cent and views in 90 per cent of spaces.  
  • Recycle cooking oil/biofuel oil closed loop innovation  
  • Green housekeeping for healthy IAQ  
  • Green education and training

How can you guarantee the energy performance of a project during its construction and lifetime? 
There is widely-used international protocol for commissioning and measurement and verification of buildings (ASHRAE and IPMVP) to ensure it is constructed as per the design intent. Green building projects must follow these protocols in the design and construction process, and should monitor performance throughout occupancy by using an integrated BMS system. 

Centra University of Tamil NaduWhat is your relationship with other parties, such as, contractors, engineers and interior designers, while guiding them in the planning, construction and maintenance of a project? 
The architect often teams up with a green building consultant and guides the whole process of sustainable design from concept through commissioning. He/she is responsible for creating a green, high-performance building and ensuring that all green design standards are being met throughout the construction process. 

What are some of the common unsustainable construction practices? 
Inappropriate and non-climate responsive design strategies, not taking advantage of natural daylighting, ventilation and passive cooling, over design in terms of sizing of HVAC (heating, ventilation, and air conditioning) systems and structural elements, wastage of materials on site etc., are a few common unsustainable construction practices. 

How can you make existing buildings more efficient? 
Retrofitting of existing buildings, especially in urban areas, is the greenest building strategy because it does not require provision of new land or infrastructure. It also reduces the amount of materials and energy in the construction process. 

How do rating systems like LEED and Griha help promote sustainable construction? 
Green building rating systems like LEED and Griha are transforming the market for green buildings by creating a set of rigorous and consistent standards according to which all buildings are measured. In some cases, they have become de facto parts of the building code, as in the requirement that all Indian government buildings over 100k sq. ft should be GRIHA certified. In the US too, many cities and departments of the US government use LEED as a minimum building performance requirement for commercial buildings. source

* Myths about green buildings 

Myth 1: Green buildings cost more: 

Myth 2: A certification is the only way out: 

Myth 3: The market demand for green spaces will wane: 

Myth 4: Green buildings are for other countries, not ours: 


The number of certified green buildings in India has witnessed a four-fold growth in the last four years.



This is testimony to the growing popularity of the concept. If one goes by the published statistics on the IGBC (Indian Green Building Council ) website, there are currently 223 registered green buildings in the country. As an absolute number, the growth has been more than four folds in the last four years.

But is that enough? The commercial real estate stock in the top seven cities alone is approximated at 310 million sqft. Further , the forecast is that commercial real estate development will grow at an annual rate of 8-10 %. With this backdrop, the number of projects committed to green design and construction are minuscule.

So how does one transform going green from a campaign of a select few to a mass movement? One obvious factor is awareness. The second most important factor is aligning corporate sustainability goals with real estate selection.

Green spaces not only allow for 14 to 16 per cent increase in productivity but also reduce the operational cost of the building, consume less energy, water and other resources , leading to office which more environmentally responsible and has a lower carbon footprint.

Thanks to the efforts of the Institute for Green Business Certification (IGBC), awareness in the corporate world has increased and green space has increased from 20,000 sq ft to about 730 million sq ft since the inception of IGBC. more

* ISHRAE to focus on green buildings in Ahmedabad

Even while the realty sector in Ahmedabad is witnessing a slow growth, ISHRAE is banking on increased need for high performance buildings of corporates. The industry body held ACREX 2012, the international exposition on Air Conditioning, Refrigeration, Electrical, Plumbing, Fire and Building Services in Ahmedabad.

Ahmedabad like many other major cities across the world, is witnessing an increase in high performance infrastructure for software companies, corporate offices and homes. This advanced infrastructure is mushrooming in the city with the support from Government and as CSR initiative of many companies,” said Pankaj Dharkar, co-chairman, ACREX 2012. source

*  Bringing greater energy efficiency to commercial buildings a $ 100 b business by 2017


Companies doing retrofits -- including Johnson Controls, Honeywell, United Technologies and Ameresco -- stand to reap the benefits from buildings going green. Property managers are also promoting the cost savings and other benefits of energy-efficient building.

Randy Harrell of CBRE said green buildings are more desirable, especially for high quality tenants.

"Most Fortune 500 [companies] filed corporate social responsibility mission statements with the SEC and real estate is a way to help them achieve that corporately," Harrell said.

The movement has evoked tremendous response amongst the various stakeholders. The vision of IGBC is to usher in a green building movement in India and to facilitate India become one of the world leaders in Green Buildings by 2015.

As on date, 1,404 projects in India have registered under the IGBC Rating programme, with a total footprint of over 1.03 billion sq. ft. Today India also has over 200 buildings which are certified and fully functional. 


Developers in Pune interested in energy efficient buildings





* Climate Talks Can Impact Green Building Worldwide

USGBC will be joining the World Green Building Council and its delegation of GBC Australia, GBC South Africa and Jordan GBC on the ground for this historic conference. As chair of the advocacy committee for the United Nations Environment Programme's Sustainable Buildings and Climate Initiative (UNEP-SBCI), I will also be working closely with the public and private sector members of that organization. Durban may indeed present a "fork in the road" for multilateral efforts on climate change. While the Kyoto question looms large for delegates, our position is clear -- that no matter what form it takes, delegates must work diligently and transparently to come to agreement on a path forward to reduce emissions; one that incorporates mechanisms like the above to rapidly finance and bring to scale clean technology solutions like energy efficiency. source


* Fire-resistant façade glass


While green buildings are on the increase, the focus is in ensuring adequate fire protection also. In addition to Solar control glasses, to reduce the heat while permitting light, builders are using fire-rated glass on the facade and exteriors of buildings, and in areas such as refuge terraces, staircase enclosure and shop fronts in tall buildings.

Vetroflam is tested in International labs for up to two hours of fire resistance, and this product has a solar factor of 0.26, and a U value of 1.5W/m2K qualifies for LEED or GRIHA ratings for green buildings and conforms to National Building Code norms. source

Frequently Asked Questions


What are the eligibility requirements for the LEED Green Associate exam?

After March 31st, 2009, candidates for the LEED Green Associate (GA) credentials must fulfill eligibility requirements.

LEED Green Associate candidates are required to do ONE (1) of the following:

Option 1: You must be (or have previously been) employed in a sustainable field of work

This is perhaps one of the more nebulous requirements posed by the GBCI, because no definition of a "sustainable field of work" is given. The USGBC does state that the company needs to "relate to environmentalism or the green building industry". If you are in any doubt that your profession would qualify, contact the GBCI at or by calling 1-800-795-1746.

Option 2: You must be (or have been) involved in a LEED Certification Project

To prove eligibility by way of LEED project involvement, you must have been involved in the certification process of a LEED registered project. This means that your name must be on the registry of a specific LEED project that has already taken place, or which is currently in progress. Note: the building does not have to have earned its LEED rating yet, it just has to be registered with the GBCI. This can sometimes be difficult to achieve, as many organizations prefer to have existing LEED APs take care of the certification process, but as there is no requirement for a person working on a LEED project to be a LEED AP, it is possible to be added to a project.

If taking part in a LEED project led by your place of business isn't an option, we are able to help. We offer a Green Professional Training Program, in which you can take part in an actual LEED certification process over the course of a few months, and when all is said and done, your name will be listed on the LEED project, making you eligible for not only the Green Associate exam, but for future LEED AP exams as well. Please contact us for details.

Option 3: You must show involvement in an education program that addresses green building principles.

This is perhaps the most straightforward of the three eligibility options for the Green Associate exam: You have to show that you've taken (or are currently taking) some sort of training course to do with Green Building. This, thankfully, is one of our specialties. We have a number of training courses available weekly, and are adding more all the time. Our classes range from one-day online classes to two-day in-person classes, and everything in between. To get started, just head to our Green Exam Prep Training section and have a look at our offerings. We have a number of Green Associate exam preparation classes happening all the time, any of which will make you eligible for the Green Associate exam!

Assuming you are able to fulfill one of those three requirements, you are eligible to register for and take the LEED Green Associate exam.

Remember that this exam is considered to be "part 1" of the LEED AP process, and is considered to be a prerequisite for the LEED AP exams. To register to take the Green Associate exam, visit the GBCI and get started today!

What is the LEED Exam Pass Rate?

The LEED AP exam pass rate is estimated to be in a range of 30%-34%.

To determine this number, has gathered reports from various established providers of LEED preparation products and courses.

The GBCI and/or the USGBC do not provide guidance on, nor do they make public, details of the various LEED accreditation exam statistics.

Are there eligibility requirements for the new LEED AP v3 exams?

After March 31st, 2009, candidates for the LEED AP credentials must fulfill eligibility requirements.

Along with the change over to LEED Version 3, the USGBC has introduced some fairly strict requirements in order to be eligible to take the LEED AP exam. We hope to be able to clear up some of the confusion surrounding these requirements so you can determine your eligibility, and if ineligible, show you the programs we offer in order to make you eligible for the test.

To take any of the Tier 2 LEED AP Exams (i.e. Building Operations & Maintenance, LEED AP Homes, Building Design Construction, Interior Design Construction) you must meet both of the following requirements:

1: You must have taken and passed the LEED Green Associate Exam

This is not made explicitly clear in the candidate handbook, but the first requirement for eligibility for the AP test is to have passed the Green Associate test. Some paperwork often refers to the Green Associate test as "Exam 1" and the AP tests as "Exam 2". There is no minimum time necessary between taking the Green Associate exam and when you take the AP exam.

For more information on the eligibilty requirements of the LEED Green Associate Exam, head here.

2: You must be (or have been) involved in a LEED Certified Project within three years.

To prove eligibility by way of LEED project involvement, you must have been involved in the certification process of a LEED project within three years of the application's submittal date. This means that your name must be on the registry of a specific LEED project that has already taken place, or which is currently in progress. This can sometimes be difficult to achieve, as many organizations prefer to have existing LEED APs take care of the certification process, but as there is no requirement for a person working on a LEED project to be a LEED AP, it is possible to be added to your businesses project.

If taking part in a LEED project led by your place of business isn't an option, we are able to help. offers our Green Professional Training Program, in which you can take part in an actual LEED certification process over the course of a few months, and when all is said and done, your name will be listed on the LEED project, making you eligible for the LEED AP exams. Call Us for details.

If you meet both of those requirements, you are eligible to register for and take any of the v3 LEED AP exams.

To register to take the LEED AP exam, visit the GBCI and get started today!

What is the Continuing Education requirement for LEED APs and LEED Green Associates?

As part of the LEED CMP (credential maintenance program), the GBCI requires that LEED Green Associates must complete 15 Continuing Education (CE) hours biennially (i.e. every two years).

LEED APs must complete 30 Continuing Education (CE) hours biennially (i.e. every two years).

Will the GBCI will accept online and/or offline LEED GA preparation courses as fulfilling the LEED GA eligibility requirements?

Certificates of Completion from eight hour online, eight hour virtual and one and two day offline LEED Green Associate prep courses sold on have been accepted by the GBCI as a valid education requirement.

However, is not affiliated with the GBCI and does not guarantee that the GBCI or any specific entity will recognize courses offered through

What do I need to know to take the LEED exam?

Candidates should refer to the LEED candidate handbooks and LEED reference guides for the fundamental information needed to pass the LEED AP exams.

Handbooks and reference guides provide an overview of the Green Building Certification Institute's ("GBCI") and Prometric's policies and procedures throughout the credentialing process as well as detailed information on the LEED rating system in the candidate's area of focus.

You may find the Candidate Handbooks and reference guides on the website. There are candidate handbooks available for the LEED Green Associate and all the LEED AP credential exams. These handbooks include exam specifications, study materials, sample questions, GBCI and Prometric contact information and application, registration, and scheduling information.

Individuals should read and understand their particular exam's handbook, including all policies, procedures, and consequences.

The GBCI states that Candidate Handbooks are valid for one month from release and they are updated, as necessary, and released on the first business day of each month.

LEED reference guides provide detailed information on the LEED certification process according to the various specialty tracks.

Is it necessary to enroll in a LEED AP or LEED Green Associate prep course before the exam?

It is not a requirement to enroll in a prep course before taking the exam, however, it is recommended.

Many students who have passed the LEED AP or LEED Green Associate exams report that prep courses helped them better understand the LEED certification process, the relevant material on green building and the science of sustainability.

What if I fail the LEED exam?

Candidates who fail the LEED exam may retake the exams as many times as they like, however they are limited to a maximum of three times per year.

If a LEED AP candidate fails the Tier II, the LEED AP exam, but passes the Tier I, LEED Green Associate exam, they do not have to retake the LEED Green Associate exam again, they only have to retake the Tier II specialty exam for LEED AP that they failed.

The exams are multiple-choice and computer-based. The first part will be the core knowledge exam (taken by Tier I, LEED Green Associates) about green building and general knowledge about the LEED Rating System.

The second part, the LEED AP Tier II specialty exam, will be focused on the specialty area of the track you choose (i.e. LEED ID C, LEED BD C, LEED for Homes, etc.)

What are LEED credential exams like? How are LEED accreditation exams administered?

LEED professional exams are computer-based, multiple-choice examinations. In both the Tier I (LEED Green Associate) and Tier II (LEED AP ) exams, candidates are given two (2) hours to take and complete the exam.

Individuals may choose to take both the Tier I and Tier II exams in one sitting if they wish, in which case they will have 4 hours to complete both parts of the exam, or they may take them sequentially, or choose to take only the Tier I, LEED Green Associate exam.

LEED professional credential exams are administered by Prometric, which is a nationwide professional testing center with locations throughout the United States. The exams are computer based and administered on location at Prometric testing centers.

Individuals taking the LEED exams at Prometric testing centers must bring several forms of ID confirming their identity and are not allowed to bring any personal belongings into the exam area. Lockers are provided for personal belongings.

What are the requirements to take a LEED Green Associate Exam?

LEED Green Associate (aka LEED GA) candidates are required by the GBCI to do the following:

1. Agree to the disciplinary policy and Credential Maintenance Program (CMP) as outlined

2. EITHER document involvement in support of a LEED certification project OR be employed in a sustainable field of work OR engaged in an education program in green building principles and LEED.

3. Submit to an application audit. Five to seven percent of all applications will be audited; you will be notified immediately if you are chosen for an audit and will be notified of your eligibility within 14 days.

How do I become a LEED Green Associate?

Individuals interested in the LEED Green Associate credential must go to the Green Building Certification Institute website at and follow the instructions for LEED Professional Credentials.

Candidates must create an account with the GBCI and then choose which credential they are pursuing, in this case, LEED Green Associate.

LEED Green Associate is the Tier I LEED Credential and earning the credential is required before becoming a LEED AP.

How do I become a LEED AP?

Individuals in becoming a LEED AP must go to the Green Building Certification Institute website at and follow the instructions for LEED Professional Credentials.

It is important to note that all candidates seeking to become LEED Accredited Professionals ("LEED APs") must first take and pass the Tier I exam for LEED Green Associate before taking the LEED AP exam. Once an individual has passed the LEED Green Associate exam, he or she has earned that credential. Individuals may then decide to proceed with taking the Tier II, LEED AP exam. Exams may be taken on separate dates or consecutively in one exam session.

How do I take the LEED exam?

Individuals must go to the Green Building Certification Institute website at and follow the instructions for LEED Professional Credentials. If you are not currently a LEED Green Associate or LEED AP, you must start with the LEED Green Associate credential before progressing to LEED AP.



Green Buildings



A building which can function using an optimum amount of energy, consume less water, conserve natural resources, generate less waste and create spaces for healthy and comfortable living, as compared to conventional buildings, is a green building.

Conventional methods of building use tremendous quantities of material, many of them non-renewable and toxic, and pay little attention to the impact the building has on the environment. Green buildings not only reduce these impacts but are also healthier and consume less energy saving money in the long run.

Green building design is a practical and climate conscious approach to building design. Various factors, like geographical location, prevailing climatic conditions, use of locally available and low embodied energy materials and design parameters relevant to the type of usage of the building are normally taken into consideration. Such an approach ensures minimum harm to the environment, while constructing and using the building.

 A green building uses minimum amount of energy, consumes less water, conserves natural resources, generates less waste and creates space for healthy and comfortable living.

 When a number of green buildings are located in proximity, they would create a green zone, providing much healthier environment and minimise heat-island effect. The ultimate aim will then be to create many such areas, which would help the towns and cities and therefore the nation in reducing total energy requirement and also the overall global carbon footprint.

*The Leadership in Energy and Environmental Design (LEED-INDIA) is a Green Building Rating System is a nationally accepted benchmark for the design, construction and operation of high performance green buildings.  There are 150 LEED registered green buildings and 23 LEED certified green buildings in India.

Chennai leads the brigade of Indian cities for its green efforts. Among the corporates, Wipro is widely regarded for its green initiatives. Incidentally Bangalore has no green building till now, inspite of its realty boom.



National Building Code

Building bye laws in India fall under the purview of state

governments and vary in administrative regions within

the states. BIS developed the NBC in the early 1980s

as a guiding code for municipalities and development

authorities to follow in formulating and adopting building

bye laws. Today, NBC is the reference standard for most

construction designs in the country. In its initial form the

voluntary code covered most aspects of building design

and construction, with only a small part dedicated to

energy effi ciency. However, the revised the NBC 2005,

in its latest version provides guidance on aspects of energy

conservation as well as aspects of sustainable development.

Th e NBC provides general guidance on potential energy

effi ciency aspects of factors like daylight integration,

artifi cial lighting requirements and heating, ventilating,

and air conditioning (HVAC) design standards. A new

chapter on sustainability is being added to the NBC to


provide a holistic approach to designing and constructing

sustainable buildings. Th e chapter focuses on the integrated

nature of design and adopts a cradle to grave approach for




Energy Conservation Building Codes


ECBC was formally launched in May 2005 as a provision

of the Energy Conservation Act of 2001. As per the Act,

ECBC will be mandatory for buildings with a connected

load of 100 kW or a contract demand of 120 kVA or more.

ECBC focuses only on the operation energy use impact of a

building and specifi c maximum and minimum limitations

on a number of key building features to reduce a buildings

energy use.

ECBC has both prescriptive and performance based

compliance paths. Th e prescriptive path specifi es the

minimum requirements for the building envelope and

energy systems (lighting, HVAC, service water, heating and

electrical) that should be adopted. While the performance

based compliance path requires the application of whole

building simulation approach to prove effi ciency over base

building as defi ned by the code. ECBC takes into account

location and occupancy of the buildings and provides

minimum standards for reducing energy demand of the

buildings through design and construction practices while

enhancing the occupants’ comfort.

BEE is facilitating the adoption of the policy at the

state level as well as providing technical support for the

development of the codes and standards. A number of

software, tools, tip sheets, case studies and a comprehensive

user manual are now ready and available to the building

professionals. Th e ECBC document is complementary to

the NBC 2005. Several references to natural ventilation,

daylighting, lighting, comfort, and other standards in the

document are also detailed out in the NBC. Th e sustainability

chapter of NBC refers to the ECBC document for specifi c

energy effi ciency standards for buildings and components.

Th e EC Act and ECBC do not directly address the small

commercial and residential building segment. Th e heaviest

energy end use in these smaller buildings is in the form of

appliances and equipment. Th is appliance energy use is

being targeted through BEE’s energy effi ciency standards


and labelling programme.

Environmental Impact Assessment

The MoEF’s EIA is an important measure for ensuring

optimal use of natural resources for sustainable

development. EIA was made mandatory in India under the

Environmental Protection Act (1986) for 29 categories of

large scale developmental activities. The requirement for

building energy performance in the EIA is a combination

of related terms in NBC and ECBC. The EIA requirements

are extremely pertinent and relevant, and if properly

implemented, will result in a significant reduction in the

environmental impact of buildings. In fact, buildings

complying with the requirements of the MoEF’s EIA will

fulfil most of the requirements of popular green building

rating systems.

Green building rating systems


There are two major green building rating systems currently

operating in India: LEED India and GRIHA. Industry

associations and the private industry have played an

important role in promoting the green building movement

in India. The Indian Green Building Council (IGBC) is

facilitating the Leadership in Energy and Environmental

Design (LEED) rating of the United States Green Building

Council (USGBC) in India. It has developed several India

specific ratings, namely LEED-India, Green-Homes and

Green-Factories. The IGBC also offers training, technical

assistance, and other capacity building programmes to

industry associations and industries.

The Energy and Resources Institute (TERI) jointly

with the Ministry of New and Renewable Energy

(MNRE) has developed the Green Rating for Integrated

Habitat Assessment (GRIHA) for the emerging energy







consuming segment - the commercial, institutional and

residential buildings. GRIHA has now been adopted as

the national green building rating system and MNRE has

developed incentives to promote it among architects and

building owners. Additionally, MNRE has initiated several

programmes for the integration of renewable energy in


Key barriers to building green in India

Sustainable building design and construction practices face

a number of complex and interrelated barriers which can

operate at various levels starting from government policy

to the technical expertise and knowledge of a construction

site worker. One key barrier to green buildings in India is

the adoption of inappropriate western design and comfort

ideals. Even though the climatic conditions and lifestyle

in the west and consequently the building designs are

drastically different, there is a tendency among the Indian

design industry and building owners/developers to ape them.

This is a critical barrier to effective energy efficient design in

the country. Although there are several excellent examples

of traditional buildings that maximise thermal and visual

comfort in buildings, these traditions need to be transformed

and adapted for modern design of commercial buildings.

At the policy level, tough mandatory standards are

seen more as an impediment to growth and industry and

most programmes prefer to opt for voluntary compliance

and less stringent standards. This attitude is shifting slowly

after the success of some of the industry and appliance

standards programmes. International examples have proven

that mandatory and uniformly implemented codes and

standards are the only way to achieve substantial impact of

any energy efficiency measure.

Integrated green




In the absence of mandatory standards for green and

energy effi cient buildings in India, most municipalities do

not have a uniform and practicable energy code especially for

passive and solar designs. Th ere are no clear implementation

guidelines in place for state and municipal bodies to develop

and implement building energy effi ciency programmes and

policies. Th ere is also no eff ective local implementation

infrastructure for code administration and enforcement

including code checking and inspections.

Building owners tend to under invest in green

technologies and energy effi ciency during building design

and construction because of the split incentives. Th e

developers do not gain from the initial investments in

building energy effi ciency and thus pass on the cost of

ineffi ciency to the tenants and the environment. Th e current

high cost of borrowing can be a strong impediment to

incremental funding in effi ciency that would be off set by

future savings of energy costs.

Overcoming the barriers:

implementation approach

Th e approach to transforming the current construction

paradigm towards a more sustainable approach can only be

achieved through collective eff ort, involving all the major

stakeholders in the construction industry, the policy makers,

the fi nancial institutions, end users, and the developer

community. A detailed action plan with time and result

bound targets needs to be developed in close consultation

with these stakeholders. At the policy level, there is still not

enough signifi cance given to the building sector. Although the

process of implementing the current ECBC, with its moderate


stringency levels, is in progress; a more dynamic and long term

future orientation of building energy policy is needed. Th e

future with a zero net energy building target, therefore, is the

next major leap forward in the policy approach. A transparent,

fl exible, and eff ective implementation mechanism needs

to be developed in order to overcome the traditional code

compliance related concerns. Th e implementing agencies

need to be strengthened and supported with technical details

and best practices. Th ey also need to be monitored to ensure

transparent enforcement. Although India has one of the

highest electricity tariff s for commercial buildings and the

costs of renewable energy systems are coming down, a major

barrier to the widespread adoption of renewable energy and

energy effi ciency technologies is the initial cost of investment.

A larger market for such products and technologies; a policy

environment providing substantive incentives for development

and implementation; and import of energy effi cient products/

technologies are necessary for high performance buildings to

be mainstreamed. ❂

Managing Director, Green by Dhruv Futnani

Dhruv is well experienced in the field of green building design and certification. His passion for integrating Green Building design with Architectural Design pushed him to start this company which is focused on True Sustainability rather than only focus on “Green Ratings”.



When a project is being developed from scratch, the opportunity to incorporate Green Building principles at the conceptual & schematic design stages and this facilitates better quality of design and incremental costs could be reduced or even negated. Computer simulation tools and analysis assists the design team. An integrated effort of the entire team results in an optimized design to meet and exceed international standards for thermal comfort, building materials and indoor environment.


The construction stage plays an important role in the Green Building concept, and practices like protection of top soil, construction waste management, the protection of building materials and reduced site disturbance. New materials which are tested to be free / low from harmful chemicals, called volatile organic compounds are also specified in Green Buildings.


Green Buildings make business sense with a triple bottom line of environmental, economic and social. The Green Movement signifies the building and construction industry’s commitment to the environment and addresses the growing demand from the commercial, residential and industrial sectors.

         Energy Conservation Building Code (ECBC)

The Energy Conservation Building Code (ECBC) was launched by Ministry of Power, Government of India in May 2007, as a first step towards promoting energy efficiency in the building sector. It is estimated that the nationwide mandatory enforcement of the Code will yield considerable annual energy savings. This, coupled with the fast growing building sector, is likely to result in a big leap towards achieving nation’s energy efficiency goals. The ECO-III Project has played a significant role in providing continuous support to Bureau of Energy Efficiency (BEE) towards developing and improving the Code, enhancing awareness and capacity building for its implementation in the country.


  • Provide technical support to BEE to implement the ECBC in a rigorous manner
  • Develop reference material and documentation to support the Code
  • Develop ECBC Training material for workshops and training programs
  • Develop a road map for ECBC implementation


  • Developed a report on “Energy Conservation Building Code Implementation Strategy in India” in partnership with Bureau of Energy Efficiency and CEPT University.
  • Developed ECOnirman Prescriptive tool, a web-based tool for checking conformance with the ECBC using the Prescriptive method. It enables building developers and designers to test their building design against the prescriptive requirements of the code. ECOnirman Prescriptive tool is a web-based conformance tool that can be made available to users over the Internet with minimal software requirements or building science expertise. It can be used with minimal learning involved. Being a web-based tool, it allows design teams to collaborate remotely. The tool requires inputs from the user to arrive at conformance results for different buildings components. A report that may be submitted to demonstrate conformance with the ECBC can be generated. Key features of the tool are:
    • Facilitates the users in assessing if a building meets the conformance requirements, keeping in view the five climatic zones in India as specified in the ECBC
    • Generates conformance reports that compile the data provided by the user; also indicates if the systems and sub-systems of the building are conforming or not conforming to code requirements
    • Stores multiple building projects under a single user profile
    • Stores the information in a central database for future reference, review, edit, and analysis purposes
    • Keeps the information secured and confidential
    • Is available in the public domain for easy access to the users
    • Offers an additional option of checking the conformance of building envelope usingthe Trade-off option
  • Developed ECOnirman Whole Building Performance tool, a web-based building energy simulation tool for checking conformance with the ECBC using the Whole Building Performance method. It enables building developers and designers to test their building design using the energy simulation protocol established in Appendix B of the code. ECOnirman Whole Building Performance tool also predicts the performance of the building in terms of its annual energy consumption normalized to the building area. Being a web-based energy simulation tool, it can be made available to users over the Internet with minimal software requirements and building science or simulation expertise. The tool runs the Standard Design (baseline parameters from the ECBC prescriptive requirements) and the Proposed Design (user specified inputs that allow the user to modify the ECBC prescriptive requirements) versions of the building and compares the Energy Performance Intensity (EPI) from the simulation results. A report that may be submitted to demonstrate conformance with the ECBC, can be generated. Key features of the tool are:
    • Facilitates the users in assessing if a building meets the conformance requirements, keeping in view the five climatic zones in India as specified in the ECBC
    • Generates a building’s conformance report that compiles the data provided by the user and also indicates if the systems and sub-systems of the building are conforming or not conforming with the code requirements

India's first net-zero building using solar power launched

Stepping in to join a global trend of adopting green technology for running office premises through harnessingrenewable source of energy, the Prime Minister Manmohan Singh on Tuesday dedicated India's first 'zero net energy' building to the nation. 

With an installed capacity of 930kw peak power, the building - calledIndira Paryavaran Bhawan -- has the largest roof top solar system among multi storied buildings in India. 

Located here on Jorbagh Road, the building has provision to accommodate about 600 officials of the ministry of environment and forests. It was constructed at the cost of Rs 209 crore. 

The zero-net energy building - also called Net Zero Building - is a structure with zero net energy consumption where the total amount of energy used in the premises on an annual basis is more or less equal to the amount of renewable energy created on the site. 

Many countries in Europe have been using green technology to cut their 'carbon foot-prints' for the sake of cleaner environment. 

The solar system at the roof-top of the Indira Paryavaran Bhawan has been generating power since November last year. The electricity, generated there, is being fed to the local grid of theNew Delhi Municipal Council (NDMC). The building is designed in such a way that 75% of natural daylight is utilised to reduce energy consumption. 

"Total energy savings of about 40% has been achieved by adoption of energy efficient 'Chilled Beam' system of Air Conditioning. This is an innovative air conditioning system, where air conditioning is done by convection currents rather than air flow through diffusers and chilled water is circulated right up to the diffuser points unlike the conventional systems", said an official statement. 

The building has an earthquake resistant structure with a total plinth area of 31,488sqm. The building covers only 30% of the plot area. 

More than 50% area, outside the building, is a soft area with plantation and grassing. Even circulation roads and pathways are a soft area to enable ground water recharge.

 India in top five position in spearheading the global green building movement: IGBC 

 India has significant opportunity to go the green way and concerted efforts by all the stakeholders is the need of the hour, said vice-chairman of Indian Green Building council (IGBC), Goa, Bharat Kamat on Thursday. 

Addressing the participants at the two-day advanced training programme on green building rating systems organised by IGBC of CII, he said by the year 2030, building stock in India is expected to reach 100 billion sq.ft from the existing 25 billion sq.ft 

IGBC , he said, with the support of all the stakeholders has opened up new green employment opportunities like third party commissioning, energy simulation, facilitation of projects, accreditation professionals. India has over 2,380 registered green building projects and is amongst the top five countries in the world involved in spearheading the global green building movement, Kamat said. 

The construction costs of a green building would be 3 to 5% higher for a Platinum building than a conventional building, but the incremental cost gets paid back within 3 to 4 years with substantial reduction in operational costs, he added. 

Ms Geetika Goyal, Head, CII Goa State Office, highlighted that CII is working closely with the stakeholders in facilitating sustainable development of the State. M Anand, principal counsellor, IGBC highlighted the activities and initiatives of IGBC in facilitating India emerge as one of the global leaders in green buildings.Courtesy:Et


Induction Cooktops for Green Building and LEED



Induction cooktops work by electromagnetism. When the unit is turned on, the magnet sensors detect a metal-bottomed pan, and produces an electric current. This cooking method is 90% efficient, which is 20-25% more efficient than electric and 60-70% more efficient than gas.


Aside from energy savings, induction cooktops maintain an even, constant temperature, which helps food to cook more quickly. In fact, it produces an instant simmer and a faster boil. Plus, the induction cooktop only heats metal cooking vessels, which means that the rest of the stove stays cool even when the pan gets hot. This makes induction cooktops safer than traditional gas or electric stoves.


To learn more about the benefits and mechanics of induction cooktops, see this previous article.


The following are three energy


1. Frigidaire Professional 36"


Frigidaire's Professional 36" Induction Cooktop (also available in 30") comes with five "burners" on a ceramic glass cooktop, and pro-select controls for precise temperature selection. One of its 10" burners has up to 3,400 watts of power for a quick boil.


The Professional 36" cooktop has an MSRP of $1,799.


2. GE Profile 30"


General Electric's (GE) Profile 30" Electric Induction Cooktop (pictured) has 4 induction "burners" on black ceramic glass, which range from 6" (1800 watts) to 11" (3700 watts). It comes with electronic touch controls with 19 settings and a child safety lock. The induction "burners" have pan size sensors, so only the pan heats up.


GE's model also has an MSRP of $1,799, though it retails on Amazon for about $1,280.


3. Electrolux Induction Hybrid


The Electrolux 30" Induction Hybrid Cooktop combines two induction elements and up to three electric elements for cooking flexibility. The burners range from 6" to 10" and have 25 digital preset touch settings for quick and precise temperature control. It has a power assist function for rapid boil, as well as a "keep warm" setting, which is great for entertaining.


The Electrolux hybrid also has an MSRP of $1,799.


LEED Credit Overview


Since it saves energy, an induction cooktop could help to achieve the following credits in the LEED for New Construction 2009 rating system:


• Energy and Atmosphere (EA) Prerequisite 2: Minimum Energy Performance (0 points)


This credit establishes a minimum level of energy efficiency for buildings, based on energy costs.


• EA Credit 1: Optimize Energy Performance (1-19 points)


This credit rewards LEED projects for achieving energy efficiency beyond the minimum set forth in EA Prerequisite 2. Points are awarded based on the energy cost savings percentage - the higher the percentage, the greater the number of points awarded.courtesy






As the U.S. green building movement enters its third decade, the market has reached a tipping point.


The 2013 global Energy Efficiency Indicator [PDF] research study of 3,000 facility management executives indicates that only 5 percent had certified a green building before 2012. Yet 29 percent plan to certify a least one facility in 2013. This represents tremendous growth, but as the market evolves for green buildings, so should the definition of green buildings. LEED v4.0, the updated USGBC rating system, takes a big step forward in this evolution.


In the next decade, buildings will become more grid-responsive, resilient, efficient, energy-positive and networked. Put those terms together, in other words, and they spell “GREEN.”


1. Grid responsive


One big change is that buildings will become more responsive to the grid. An early example of grid interaction includes demand response, where building owners agree to curtail non-critical building loads or turn on back-up energy sources during grid emergencies in return for compensation from utilities, grid operators or demand response aggregators. The 2013 EEI survey indicated that 14 percent of U.S. organizations currently participate in demand response programs. This capability, however, represents just the tip of the iceberg when it comes to the opportunity for buildings to provide valuable and profitable services to the electrical grid. Through the use of automated demand response [PDF] and predictive controls, building energy consumption can be continuously adjusted to reduce demand at critical times of the day in response to hourly pricing signals from the grid. An early adopter of this strategy is Georgia Tech, where the campus-wide building management system downloads current and predicted future energy prices every hour over the Internet and adjusts temperature set points across the campus, reducing demand by up to 7 percent. Other, more advanced capabilities include providing spinning reserve and grid regulation services. In these cases, building energy demand is required to respond to signals with either a 10-minute or four-second response. This is a perfect application for site-based electric battery storage.

Experiments at our Johnson Controls corporate headquarters facility demonstrated the capability to track a four-second test signal from the PJM grid operator with 97 percent accuracy using Li-ion batteries and a commercial building management system. When not providing grid regulation services, the batteries also can be used for demand limiting and PV solar firming.


2. Resilient


Superstorm Sandy taught us that the design and operation of our buildings is critical to minimizing damage, maintaining operational integrity and providing critical services during and after extreme weather events. Following Hurricane Sandy, many grid-connected solar PV systems were not operational because of safety systems installed to protect utility workers and grid integrity. The availability of even a limited amount of solar energy or distributed generation, combined with energy storage and a secure grid disconnect mechanism, would allow buildings to provide critical services over extended periods of time.


One key recommendation in the August Hurricane Sandy Rebuilding strategy reinforces the important role that distributed energy systems and smart building controls can have in improving community resiliency. “The new approach would define policies and technical requirements for how to incorporate smart grid technology, microgrids, building controls and distributed generation, including CHP, with two-way flow networks into the grid. … This approach would allow building controls to provide a minimal level of service such as basic lights and refrigeration during emergencies,” the strategy noted.


In the 2013 EEI survey, 51 percent of U.S. respondents said they had installed or plan to install distributed generation with reliable fuel sources to provide power for extended periods. Additionally, 39 percent said they installed or plan to install solar panels with a secure grid disconnect mechanism to use as an emergency back-up system.


3. Efficient


Building efficiency has continued to improve over the years, resulting in significant energy and operational savings. Our EEI research indicates that lighting, HVAC and controls are the most popular energy efficiency improvement measures; more than two-thirds of organizations have made these improvements in the past year. An increasingly important area of attention is energy-focused behavioral and educational programs, where 44 percent said they had implemented improvements in the past year. Organizations approach behavioral efficiency improvements in a number of ways. In the United States, green teams or champions have been employed at 36 percent of organizations, while social media tools have been used by 34 percent of organizations. Other approaches include creating sustainability games or challenges (22 percent) and installing green kiosks (21 percent). A new study from the Institute for Building Efficiency summarizes best practices in workplace sustainability engagement and includes an online tool to help organizations prioritize the best engagement tools and practices for their employees.


4. Energy positive


While energy efficiency always should be the first step in reducing the environmental footprint of buildings, there is growing interest in near zero, net zero and energy positive buildings. Hundreds of successful net-zero energy buildings are in the United States. The State of California has included net zero energy as a 2030 goal for commercial buildings in its energy efficiency strategic plan. Despite the technical and economic challenges of net zero energy, 46 percent of U.S. organizations responding to the 2013 EEI survey said they intend to achieve near zero, net zero or energy positive status for at least one facility in the future. The U.S. Department of Defense is at the leading edge of net zero energy facilities. The U.S. Army has established a net zero initiative that includes achieving net zero energy, water and waste at a number of installations around the world. There are a number of advantages to considering energy positive goals at a campus or community level. One upside is improved economies of scale, with distributed energy and district cooling and heating plants designed to serve multiple facilities. Also, retrofitting existing large commercial buildings to net zero energy can be extremely expensive or impossible depending on the configuration.


5. Networked


The final area of innovation in GREEN buildings is networking. Smart building or smart grid technology was installed by 19 percent of U.S. EEI survey organizations last year. Smart building technology provides the data and information infrastructure needed to measure building conditions, monitor building performance, control building systems and manage energy and assets across a building, campus or enterprise. Smart building technology was rated the second most likely technology to increase in market adoption over the next 10 years.


The Empire State Building retrofit project is a good example of the benefits of implementing smart building technology. It’s predicted that the retrofit project will result in energy savings of 38 percent. Of this, 20 percent is due to building management system improvements including building-wide implementation of digital controls, wireless sensing, demand-controlled ventilation, automated day-lighting and intelligent plug-load controls. A tenant energy portal also supports employee engagement and behavioral change programs.


The future of “GREEN” Buildings


Not only is green building technology moving forward, but green building rating systems are improving as well. LEED v4 includes a number of new credits and prerequisites that support these new industry trends and capabilities, including enhanced lighting and plug-load controls, building-level and advanced energy metering, measurement and verification, demand response and indoor air quality monitoring. Source




A unique software application created by the Energy Department's National Renewable Energy Laboratory (NREL) could improve the efficiency of commercial buildings by allowing occupants to interact with buildings more directly.

The new Building Agent (BA) application allows facility managers to quickly diagnose and adjust for problems based on direct occupant comfort feedback. Occupants are able to share this feedback via the application dashboard on their . With 25% of a 's energy performance directly related to occupant behavior, this capability can result in a significant step toward helping buildings become more cost effective and energy efficient.more..


 With green buildings making up less than five percent of the booming Indian building market, developers, governments and experts reiterated the tremendous opportunity for expanding energy efficiency construction in India during the Green Building Congress 2013.  This 11th Green Building Congress focused on market transformation opportunities with new construction, retrofits, and residential buildings as well as the importance of codes and standards. more..



Glad to note that IT ocmpanies are setting the trend. Soon others will follow. India needs to set standards for eco friendly buildings. Whether it is corporate buildings or homes.   Virtusa Corporation (NASDAQ: VRTU), a global IT services company that combines innovation, technology leadership and industry solutions to transform the customer experience, announced today that it has been awarded the Leadership in Energy and Environmental Design (LEED) India ‘Gold’ rating by the Indian Green Building Council  (IGBC) for its Hyderabad campus in India. The award is a testament to Virtusa’s overall sustainability focus which is their consistent effort to reduce environmental footprint, demonstrate ethical maturity and respect all.   The LEED Green Building Rating System is a globally accepted benchmark for design, construction and operation of high-performance green buildings. The certification is awarded to encourage and facilitate the development of sustainable buildings in India.  



UoP's School of Energy Studies lays guidelines for installing solar systemsFollowing complaints that there are difficulties setting up solar water heating systems in high rises and multi-storey buildings, the University of Pune’s (UoP) School of Energy Studies, in association with the ministry of new and renewable energy (MNRE), drafted guidelines on installation of solar water heating systems (SWHs) for such dwellings.

Such guidelines on solar water heater system have been laid for the first time. There were no written guidelines before this.

The guidelines stress the need to incorporate the system at the designing level. In fact builders must be made to create sufficient space while constructing high rises for the installation of solar water heaters.

“Laying these systems on small buildings is easy, however, it is challenging to install these solar water heaters on high rises as the consumption of hot water by the occupants is high and there are other constraints, such as limited terrace area and longer pipes,” said SV Ghaisas, the director at UoP’s School of Energy Studies.more..




The Union Government will soon finalise a draft policy to provide non-financial incentives to encourage green buildings, said Arun Kumar Misra, Housing Secretary. 

Addressing the Green Building Congress on Saturday, he said the Housing Ministry was supporting a number of incentives such as allowing additional built up space – over and above the permitted Floor Area Ratio or Floor Space Index, transferable development rights and interest subvention to encourage green buildings.

Green buildings or environment friendly buildings which are designed to conserve water, electricity and use recycled material in construction are key to addressing the challenges posed by the pollution in cities.`more..




First the theory. Training sessions. Then practice.That is exactly what is happening in Maharashtra regarding eco friendly buildings. Be it government bukildings or private buildings Looking at the reality boom in the city, the Visvesvaraya National Institute of Technology(VNIT) has been making conscious efforts to promote the concept of green buildings among public as well the people and agencies involved in construction industry.

Thanks to this awareness, a number of government as well as private agencies or builders have starting opting for green buildings. Though the Public Works Department (PWD) in the city has not as yet announced any green building project, there is a clear inclination towards the concept..MORE..  





  In what could be a boon to the construction and building industry in the country, the Centre for Advanced Research in Building Science and Energy (CARBSE) at Cept Universityhas developed a 'U-Factor calculator' along with a unique database that will prove beneficial in selecting building material, help in analysis and building energy modelling. 
U-Factor, in simple terms, means 'rate of heat transfer'. So, lower the U-factor, lesser the heat transfer through walls, roof and windows of any building. While many such stand-alone calculating tools are available, the database which Cept has generated is the first of its kind. more..

Sustainability in the built environment is about more than fitting buildings with the latest 'green' technology. Experts discuss why a holistic approach involving all stakeholders is needed

The energy efficiency of buildings is not a niche sustainability and climate-change issue. Buildings account for about 43% of the UK's carbon emissions, according to 2009 figures. The built-environment sector has, with a significant shove from regulation, focused on bringing this figure down – but, with progress slow, is it time to reassess just how realistic carbon-neutral buildings are? Or are new approaches and technologies emerging that will make sustainable buildings a reality?


       Roofs with solar systems

Senior industry experts addressed these questions at a recent Guardian roundtable, in association with climate-control systems manufacturer Climaveneta.


At the outset, Phil Draper, sustainability manager for Broadgate Estate, questioned the use of the word sustainability within the sector. "There is always some confusion about what 'sustainable' means," he said. "Sustainable is making [a building] with a longer life economically, as well as for energy savings."


Land Securities, one of the largest real-estate investment trusts in the UK, also believes economics lie at the heart of sustainability. Its head of sustainability and engineering, Neil Pennell, said: "There's no point building a really [environmentally] sustainable building that people don't want to be in."


While those assembled could list many examples of technology at the cutting edge of energy efficiency – from HVAC (heating, ventilation and air conditioning) to LED lighting, ground-source energy systems, rainwater harvesting, solar water heating and fuel cells – the economic case for these has yet to be made effectively.MORE..




In around two years from now, students and faculty of IIM-T will get to study and exercise in a four star-rated 'green building' with the very latest in audio and visual tools.

The well-stocked library would have 9,000 volumes of books and journals.MORE..


India is getting its first net-zero energy building - the Paryavaran Bhavan building in New Delhi. It is environment ministry's headquarters 

It's expected to achieve LEED INDIA-Platinum and a five star rating for Integrated Habitat Assessment from the national government's Energy and Resource Institute. Managed by the Central Public Works Department of India, the project is spearheaded by the Indian Ministry of Environment and Forests.


Net-Zero Energy India


A passive solar design brings light into most of the building as well as keeping heat out during the warmest months. 

Solar PV provides all the electricity and solar thermal provides hot water for the building. A 930-kilowatt SunPower solar system graces the roof, installed with a five-degree tilt to optimizeenergy output (1.5 million kilowatt hours a year). 

"For this urban project, with very limited rooftop space and high energy generation requirement, the selection of high efficiency solar panels was the most critical aspect," says  Ram Avatar of New Delhi-based Swadeshi Civil Infrastructure, which did the installation.more..




Delhi Development Authority (DDA) proposes to build two land mark buildings that are being designed as per green building norms. The two buildings will be built at (i) Socio Cultural Centre at Dwarka,, (ii) Office-cum-record room at Gazipur. 

The proposed incentives shall be based on the rating criteria prescribed by ‘Green Rating for Integrated Habitat Assessment’ for green buildings wherein a maximum incentive up to 5% of extra FAR and Ground Coverage may be given as an incentive by the local bodies. 
This information was given by Minster of State for Urban Development Shrimati Deepa Dasminshi in the Rajya Sabha. more..


When you scour the world of solar energyresearch for potential game-changing advances, most people would focus on a few areas: high-efficiency solar cells, transparent solar cells, hydrogen through solar water-splitting, or solar thermal.
Last week saw breakthroughs in the first three of these fields, and three weeks ago there was another breakthrough in solar thermal.
There is a strong possibility that at least some of this research will result in successful commercial technologies in a few years, expanding the possibilities of solar energy and making it work without subsidies.SOURCE




Green buildings, sustainable design and green architecture can ensure that the impact of constructions and infrastructure development on the environment is contained, former President APJ Abdul Kalam said at the GreenCo Summit 2013, which was inaugurated in the city on Monday. Kalam advocated continuous research by recyclers, electronic systems manufacturers and user groups to make green energy cost-effective.SOURCE 



Delhi will soon have its own green building design manual. Chief minister Sheila Dikshit has asked the central public works department (CPWD) to come up with a guideline to build environment friendly buildings to bring down the power consumption in the city. Dikshit said that while steps have been taken to promote rain water harvesting and to convert waste to energy, there is also a need to make our buildings and houses environment friendly.SOURCE



Experts at the CII sponsored two day conference on 'Green Buildings' demanded the government to lead a vigorous Green Buildings Movement in India, including Eastern Region.

“The Government must lead by example by transforming Government Buildings into ‘Green’. They must set an example. If we are really serious about building a Green India, the Government must show the way and convince people of the need to conserve our finite resources,” said Binoy Dutta, Chairman, West Bengal Pollution Control Board (WBPCB).  SOURCE

      green buildings used recycled material in construction, rainwater was harvested, grey water was effectively utilised.  How would it be if nature's finite resources could be saved, [water, earth, fuel] by constructing intelligent buildings that monitored the use of electricity,  water and air.   In the 20th century we looked with awe at how high buildings could be constructed with steel and glass but now in the 21st century we will look in awe at  buildings that are  living systems; seeing offices not as static environments, but as dynamic ecosystems of people and intelligence.    Here systems are not managed separately, rather they interoperate. Thousands of sensors can monitor everything from motion and temperature to humidity, precipitation, occupancy and light. The building doesnt simply coexist with nature, it harnesses it. Such buildings can reduce energy consumption and CO2 emissions by 10% to 50% or more and save 20% to 50% in water usage.   The technology that manages facilities can operate like a living organism that can sense and respond quickly, in order to protect citizens, save resources and reduce carbon emissions. Such buildings hold a key to the economic and environmental sustainability of urban environments.  We will soon see such an 'Intelligent Building' in Delhi.     GreenSpaces office park in Delhi on which construction will begin this year. It aims to be the worlds greenest and most energy-efficient commercial building, through such innovations as 100% waste and water reclamation, instrumentation and interconnection of all systems, recharging ports for electric cars and ventilated chairs. It even plans to grow its own oxygen and remove harmful compounds from the air through the strategic use of indoor vegetation, which doesnt just help the environment; it also helps people think and be more productive.Read more at Like

    An area of focus for the state governments is encouraging green buildings. I think energy efficiency and conservation in the construction sector is by far where the maximum change is possible.

    This sector itself leaves about 20% of greenhouse gas emissions in the country. If we can make any small difference in this sector, the results will be large. So we have taken a lot of care to make green buildings happen.

    The Ministry of Environment has given an order that if any building goes by the green norm, it will be taken up with top priority for environment clearances.

    Slowly we are moving towards only-green buildings. This is one of our key focus areas for the environmental vision we are working towards for Mumbai.

    There is a new policy called the Cool Roof policy.

    This is practised in some other states but we are yet to do it. We are still working out the statistics. This is a very good way of conserving energy. It is mainly by painting one's roof completely white or green. I am told that the quantum of energy that can be saved is very high.

    From afar, the EcoArk Pavilion in Taipei has the look of many modern structures that grace the world's biggest cities.Its walls are constructed of interlocking plastic bottles.The polygonal bottles are made of recycled PET plastic which is environment friendly and cheap. 
    Miniwiz (a finalist in this year's Asian Innovation Awards for designing the building and making the bricks) founder and Managing Director Arthur Huang said making a structure out of the bottles reduces construction and material costs by 30% compared to a traditional building, and given that in Taiwan construction and materials account for 60% of a building's cost, that means real savings.
    The bricks can be blow-molded on a construction site out of shredded bits of PET plastic, the type of plastic found in water bottles. They are then stacked into rectangular panels without the use of chemical adhesives. Then workers cover the bricks with a film similar to the coating used on smartphone screenswhich makes the panels fire retardant and waterproofand hang them on a steel frame. The air inside the bottles serves as a natural insulator and the film can be laced with light-emitting diodes, or LEDs, to provide low-cost lighting.
    The modular nature of the panels formed by the bottles means that buildings made of Polli-Bricks can be easily taken down and the panels re-used.

    A US-based climate conservation body has awarded gold rating to a commercial complex in the city to acknowledge the energy consumption measures adopted. With the certification of LEED (Leadership in Energy and Environment Design) Gold rating by the US Green Building Council (USGBC), the


    business centre in Sector 45 has become part of the league of four such buildings in Gurgaon.

    Earlier, the ITC Green Building, Wipro Green Building and IRRAD headquarters have got similar certification. The new complex designed by Unitech has also been approved by the Indian Green Building Council (IGBC).

    Unitech officials said the commercial tower has various features which help in minimising pollution and reducing water consumption.  The waste products generated during its construction were segregated and more than 90% was diverted from landfill by reusing. Also, low volatile organic compound paints and adhesive was used to enhance indoor environment for the occupants comfort. The complex also has various water efficient fixtures and uses recycled water for flushing.

    Measures taken during constructionMeasures that can be taken during construction are aimed at:

    • Efficient utilisation and conservation of resources
    • Promoting recycling and reuse of materials
    • Ensuring healthy living conditions
    • Reducing the global warming potential
    The steps involved in this phase are:1. Soil and landscape conservationSoil and vegetationPriority: The top soil and existing vegetation need to be preserved duringconstruction.Reason: The natural ecosystem of the site can use the existing climatic and soilconditions to maximum advantage. Changes to the soil conditions can severely harm the ecosystem which then takes long time to revive itself.2. Conservation and efficient utilisation of energy and resourcesWater managementPriority:Water should be efficiently used during construction.
    Reason: A lot of water is required during construction. This water should berecycled and reused as much as possible. Proper measures should be taken to harvest rainwater even during the time of construction and wastage of water should be curbed.3. Waste managementWaste managementPriority: Waste generated during construction should be recycled and reused.Reason: Construction waste can be reused for a variety of purposes. Thiseliminates the requirement of their disposal.4. Health and well-beingPollutionPriority: Proper sanitation facilities should be provided for constructionworkers. Cleanliness of workplace with regard to material storage and waste disposal should be ensured.Reason: Provision of proper sanitation facilities reduces pollution during thetime of construction. Proper storage of materials reduces loss and wastage.source MNRE Like

    Monier PV Tile first product to be awarded BIPV certificate by TÜV SÜD

    Visit for further information

    Monier PV Tile is the first product to receive the "Building Integrated Photovoltaics" (BIPV) certificate by TÜV SÜD. The certificate confirms that the system fulfils a comprehensive list of rigorous criteria.

    Submitted on 07/31/12, 01:16 AM

    Building integrated photovoltaics (BIPV) is a term describing multifunctional building components that generate power while replacing conventional building materials. Given the multi-functional characteristics of these components and systems, no specific BIPV standard, covering all applicable requirements related to electrical and building safety has been available to date. 

    To close this gap and enable manufacturers to provide robust evidence of the safety and quality of their products, TÜV SÜD developed a BIPV certificate which covers all applicable legal requirements of the European Union. "Our certificate provides reliable and informative guidance through a relatively new market segment, offering all stakeholders – manufacturers, retailers, installation companies and investors – enhanced certainty for their decision-making processes", says Andreas Faißt, photovoltaics expert at TÜV SÜD Product Service GmbH. 

    The certificate also provides home-owners with a valuable decision-making aid. The certificate for Monier's in-roof solution, for example, assures home owners that the BIPV product fulfils the roof's functions regarding mechanical stability and fire safety. TÜV SÜD's experts based their comprehensive list of criteria for BIPV products on the requirements defined in EU Regulation 305/2001, which will replace the European Construction Products Directive 89/106/EEC in July 2013. 

    "TÜV SÜD now serves the whole Photovoltaic value-chain from upstream to downstream players", adds Dr. Ing. Robert Puto, global head of Photovoltaics at TÜV SÜD. "We offer a wide range of new services covering crucial aspects, such as PV reliability with the so-called Thresher Test, qualification of PV inverters to grid interconnection regulations and Smart Grid operability and – last but not least – assessment and validation of a PV plant as a whole." 

    As a global supplier of building materials for pitched roofs offering a comprehensive range of roof, chimney, ventilation and energy systems for residential buildings, the Monier Group makes impartial, third-party confirmation of their products' quality and function a high priority. 

    "This confirmation is particularly attractive for innovative technological solutions as it boosts the confidence of roofers, installation companies and, of course, also consumers in the products", says Jens Milnikel, head of global solar activities at Monier Group. "We are delighted that by issuing the certificate, TÜV SÜD has confirmed the multiple functions and safety of our Monier PV Tile system as well as the high quality standards of our company." Monier Group markets the PV Tile system under their local brands and trade names: 'Braas Photovoltaik Indach Premium' in Germany and 'Redland Solar PV Tile' in the UK.
