Used by building design experts around the globe, the Virtual Environment (VE) is a suite of integrated analysis tools for the design and optimization of buildings. The IESVE platform leverages the world-leading simulation engine (APACHE) to allow cross-team collaboration between architects, engineers and contractors, from Schematic Design to Post-Occupancy.
For whole-building performance insights you can trust, look no further. Tried and tested over three decades, our unrivalled APACHE simulation engine sits at the heart of the IESVE software to provide accurate analysis across a range of performance metrics and decarbonisation options. Encapsulating the intelligence of building physics to truly understand how your buildings will perform, now and in the future.
