The trial provides complete access to all VE applications and navigators for 30 days. The trial grants full functionality, including the APACHE simulation engine, RadianceIES for advanced daylighting, SunCast for solar analysis, and the ApacheHVAC tool for system design.

IES offers a fully functional trial of the VE suite for evaluation purposes.
What sets IESVE apart is its "integrated" nature. Unlike fragmented tools that handle lighting or mechanical systems in isolation, IESVE uses a central data model powered by the Apache simulation engine. This allows for a holistic analysis where one change—such as increasing window-to-wall ratios—automatically updates the calculations for solar gain, cooling loads, and daylighting. This synergy ensures that design decisions are balanced; for instance, a designer can optimize for natural light without accidentally causing the building to overheat.
IESVE is a primary vehicle for meeting international green building standards like LEED, BREEAM, and various regional energy codes. Its ability to perform sub-hourly simulations provides a granular look at how a building behaves under specific local weather conditions. This precision is vital for the "decarbonization" of the built environment. By simulating passive strategies like natural ventilation and active technologies like heat pumps or solar PV, engineers can prove the viability of low-carbon designs to clients and regulators alike.
