Designed for speed and clarity

Better Building provides a comprehensive environment for energy modelling, from early-stage zoning to detailed HVAC and solar performance. You can import CAD drawings, define zones and levels, add renewable features, and automate shading studies, all within a fast, visual interface. With built-in EnergyPlus™ support, simulations are rapid and reliable, helping you make better design decisions, faster.

Levels + Roofs

Quickly stack levels and define roof structures, reducing modelling errors and improving 3D accuracy.

Shading

Add and configure site or local shading elements with flexible tools to test solar access and reduce energy loads.

Renewables

Include solar PV systems directly within your model, enabling early analysis of renewable contributions.
