Accept the terms and conditions. Choose your installation path (the default C:\Program Files\IES is recommended).
Open the IES Virtual Environment. When prompted, select "Request Licence Keys." Depending on your chosen trial or free module, the keys will be generated or sent to you via email. Once you input the keys, the software will activate, and you can begin using it.
IES offers a completely free tier called VE Lite . It is not a trial (it doesn't expire), but it is limited to specific modules and building size. IES VE processes massive amounts of computational data
If you want, I can:
Before downloading, ensure your system meets the minimum requirements. IES VE is supported on 64-bit versions of Windows (Vista, 7, 8, 10) and can run on Mac OS via virtualization software like VMware Fusion or Parallels Desktop. Minimum hardware includes a 2Ghz CPU, 2GB RAM, and a dedicated OpenGL-compliant graphics card, though more powerful hardware is recommended for large projects.
If your needs are more specific, IES provides a standalone free tool called . This is a legacy yet still available free tool from IES that calculates a building’s energy consumption and carbon emissions, also providing benchmarks. VE-Ware is a plugin for the free 3D modeling program SketchUp and offers a quick, iterative way to assess the environmental performance of a design. It allows architects and designers to test early-stage design ideas for energy, daylight, and water use. You can find the download link and more information by searching for "VE-Ware" on the IES website. These tools are widely respected in the engineering
EnergyPlus is the most comprehensive, free, open-source building energy simulation program available. Developed by the National Renewable Energy Laboratory (NREL) and funded by the U.S. Department of Energy, it serves as the calculation engine behind many commercial software packages.
Includes a SketchUp plug-in that allows you to draw building geometry easily and seamlessly run EnergyPlus simulations.
While the full simulation engine requires a paid license, the following components are available at no cost:
