Existing buildings account for over 30% of global energy use – but many remain energy-inefficient due to outdated HVAC, poor insulation, or legacy lighting systems.
Retrofits offer one of the fastest ways to slash carbon emissions and operational costs – and now, AI makes them smarter, faster, and more financially accessible.
🎯 How AI Can Make This Product or Solution Much Better
🧾 Energy Audit & Retrofit Opportunity Identification
AI analyzes historical energy bills, IoT sensor data, weather trends, and occupancy patterns to identify where energy is being wasted.
It automatically flags retrofit opportunities in HVAC, lighting, plug loads, insulation, and glazing – ranked by ROI, energy savings, and payback time.

View full playlist🧱 Building Envelope & Equipment Diagnostics
Using thermal cameras, LiDAR, and computer vision, AI pinpoints insulation gaps, air leaks, thermal bridges, and window inefficiencies.
It also benchmarks chillers, motors, and boilers to flag equipment that should be replaced or tuned for better performance.
🛠️ Tailored Retrofit Planning and Simulation
AI simulates multiple retrofit scenarios (LED upgrades, VRF HVAC, smart thermostats, triple glazing) to compare energy impact, emissions reduction, and cost.
Multi-objective optimization helps select retrofit bundles that best match budget, local climate, energy targets, and occupant schedules.
💸 Project Prioritization and Financing Models
AI tools evaluate building typology, usage, and policy incentives to recommend retrofit pathways with high financial and carbon returns.
It can also model ESCO contracts, on-bill financing, and carbon credit paybacks, unlocking access to capital for building owners.
🔍 Post-Retrofit Monitoring & Continuous Optimization
After upgrades are installed, AI monitors performance drift, usage anomalies, and occupant behavior to ensure savings are realized.
It flags new opportunities for O&M tweaks or digital tuning, keeping energy performance optimized year-round.
