The IES Virtual Environment (VE) is an extensive analysis tool suite for building design and retrofit, fostering collaboration among architects, engineers, and contractors from concept to operation. It integrates energy and performance analysis throughout the building lifecycle.

Central to VE is the APACHE simulation engine, a trusted tool for over 30 years, delivering accurate performance metrics and decarbonisation options. This leading engine captures building physics intelligence to predict and optimise performance, offering reliable insights for current and future designs.

Virtual Environment makes it possible to monitor the different aspects that contribute to the sustainability of the building throughout its lifecycle:

• Architecture

• Compliance

• Light

• HVAC & Loads

• Airflow

• Energy & Carbon
