Design better performing buildings.


All the analysis you need


Track valuable performance metrics such as Energy Use Intensity (EUI) and see what factors are impacting your annual energy use.


Use key daylight metrics such as Spatial Daylight Autonomy (sDA), Annual Sunlight Exposure (ASE), Direct Sunlight, Annual or Date and Time, and Daylight Factor to analyze and visualize your building’s daylight, reduce glare, and optimize natural light.

Thermal comfort

Understand how glazing, shading, and natural and mechanical ventilation impact the comfort of your spaces using sensitive metrics such as Operative Temperature and Predicted Mean Vote (PMV).

HVAC sizing

Understand how peak loads such as heating and cooling are impacting your plant sizing and find passive and active strategies for reducing them.
