Mix And Match Your Perfect Suite
A flexible integrated system for performance assessment that brings productivity and excellence to every aspect of sustainable building design.

Model Building
The single central 3D data model at the heart of the system provides geometry and data shared by all tools
ModelIT
- Collates & shares information on geometry, materials, occupancy, climate and equipment
- Enables you to create a 3D analysis model from scratch
- Alternatively, import CAD data into the system in 3D or 2D
- SketchUp, Revit, Affinity, gbXML, DXF imports supported
- Stores data in one central place & creates dynamic visualisations
Energy/Carbon
