Sustainable Design & EngineeringTurning design concepts
into measurable performance outcomes.
At PuzzeGreen, we use advanced Building Energy Simulation tools such as eQuest®, IES-VE®, and HAP® to model, analyze, and optimize building performance across diverse climatic zones and typologies. Our simulations go beyond compliance — they drive efficiency, comfort, and sustainability right from the design stage.
Through detailed modelling of envelope characteristics, HVAC systems, lighting, occupancy, and operational schedules, we evaluate a building’s complete energy profile. This helps clients visualize annual consumption patterns, identify inefficiencies, and achieve substantial savings in both energy and operational costs.
Our data-driven approach bridges architects, engineers, and sustainability consultants — ensuring every design decision is backed by performance insight and environmental responsibility.
Key Focus Areas:
Whole-building energy performance simulation
HVAC load analysis and system optimization
Renewable energy integration and feasibility
Climate-based energy benchmarking
Comparative studies for design alternatives and retrofits
