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.
Drawing

Import, calibrate, and zone directly from your floor plans using a powerful CAD interface designed for precision and speed.

Admin

Easily name, colour, and manage zones for better clarity, making your model more understandable and shareable.

Tagging

Apply tags across your model to simplify specifications, speed up workflows, and maintain consistency throughout.

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.

Envelope

Define walls, glazing, floors, doors, and skylights at global or zone-specific levels to suit diverse design strategies.

Occupancy & HVAC Profiles

Customise lighting, equipment, and HVAC usage patterns to reflect real-world conditions and optimise performance.

Simulation & Results

Run fast, robust EnergyPlus™ simulations with clear outputs, 3D geometry comparisons, and export-ready reports.
