IES VE is not suitable because the trial expires. Instead, download EnergyPlus + OpenStudio or eQUEST – both are permanently free and highly respected.

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.
