IES stands for Illuminating Engineering Society. These files are a type of plain text file that can contain data on light. More specifically, IES Photometric Files are used for architectural programs that can simulate light, for example in the mock-up of a building.
How can you open IES files?
You can open them one of two ways – using one of the dedicated programs that can execute the visual elements contained in the file, or with a simple text editor. As the files are plain text, they can be opened and viewed, however the visual information contained within won’t be shown properly.
What programs work with IES files?
IES files can be opened with programs like AcuityBrands’ Visual lighting software, RenderZone from AutoDesSys, Photometrics Pros, Lighting Analysts’ Photometric Toolbox, Autodesk’s Architecture and Revit software, and LTI Optics Photopia.
They can alternatively also be opened with plain text editors like Notepad++.
