OpenStudio Application Suite
OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance. OpenStudio is an open source project to facilitate community development, extension, and private sector adoption. OpenStudio includes graphical interfaces along with a Software Development Kit (SDK). Visit the OpenStudio website for more information, downloads, and support.
The previous version of OpenStudio (now called the Legacy OpenStudio Plug-in) only included the SketchUp Plug-in. If you are still interested in the previous version, please visit the Legacy OpenStudio Plug-in for SketchUp page.
