OpenBuildings - OpenBuildings Energy Simulator

OpenBuildings Energy Simulator is the complete solution for analysis of building energy performance and sustainable design.

Utilising industry leading standards ASHRAE, CIBSE, EnergyPlus, Radiance, and PartL, OpenBuildings Energy Simulator allows Building Service Engineers, Architects, and Sustainability Professionals to fully assess design for both new construction and retrofits.

With these capabilities users can easily simulate heating and cooling loads, assess overheating, simulate HVAC performance, comply with building regulations for energy performance, simulate internal daylighting levels, and analyse Carbon and Energy usage - enabling better-performing, more sustainable buildings that consume less energy, provide greater occupant comfort, and lower lifecycle operational energy costs.
