Tested and verified against ASHRAE 140, the Building App is for simple and complex buildings, with a unique post-processor to automate AU/NZ building code compliance. After H1 Energy Efficiency or Section J JV3 simulations? Workflows 20 X faster than a standard desktop solution? Energy, daylight and carbon assessments all in one place? In that case, the Building app is for you.


Design with your plans and drawings. Using our CAD interface, import and calibrate your floor plans, add and edit zones, nominate grid settings, set viewer preference and get results fast.
