Why This Tool Exists
Architects and mechanical engineers spend weeks on building performance analysis during design development, delaying design decisions. Traditional energy modeling tools require extensive setup and take days or weeks to run simulations, making it impractical to explore multiple design alternatives in early conceptual phases.
Real-time performance analysis platform that runs full annual energy, daylighting, and carbon simulations in minutes instead of weeks. Integrated plugins for SketchUp and Revit provide instant feedback on design changes, enabling architects and engineers to explore multiple alternatives during conceptual design phases.
