OpenStudio is supported on Windows 7 - 8.1 (32-bit & 64-bit), OS X 10.9 - 10.10 (64-bit), and Ubuntu 14.04 (64-bit).

OpenStudio 1.6.0 works with EnergyPlus 8.2.0 Update 1, which is now bundled with the OpenStudio installer. It is no longer necessary to download and install EnergyPlus separately.

Download and install SketchUp

  1. The OpenStudio SketchUp Plug-in requires SketchUp 2015 (not available for Linux). Older versions of SketchUp are not supported. SketchUp 2015 is available in 32 and 64-bit versions; the 32-bit version of OpenStudio on Windows will only work with the 32-bit version of SketchUp 2015 and the 64-bit version of OpenStudio will only work with the 64-bit version of SketchUp 2015.

Download and install OpenStudio

  1. Login to the OpenStudio website. Create an account if you don't have one.
  2. Click Downloads at the top of the page.
  3. Choose the installer that matches your operating system. The OpenStudio package contains the following tools:
  • SketchUp Plug-in
  • OpenStudio Application
  • ParametricAnalysisTool (PAT)
  • ResultsViewer

Optional - Create a Building Component Library (BCL) Account

BCL content can be accessed from within the OpenStudio SketchUp Plug-in and from the standalone OpenStudio application. To take advantage of this integration, you will need to follow the steps outlined here to request a BCL key.

  1. Login to the Building Component Library (BCL). Create an account if you don't have one. Follow the instructions from the email sent to you upon registration and then login.
  2. Click on My Dashboard near the top right of the website.
  3. Copy the text after API v1.1 key: then paste the key into the SketchUp Plug-in, the OpenStudio application, or the Parametric Analysis Tool (PAT). You only need to configure the key in one place and it will be used globally throughout the OpenStudio tools. Additionally, this key will be maintained when you install updates to OpenStudio.

Enter the key through the OpenStudio SketchUp Plug-in under the menu Plugins->OpenStudio User Scripts->Building Component Library->Setup BCL Key and click OK. Or register the key through the OpenStudio Application under the menu Components & Measures->Find Components. If a key is not already registered, it will prompt you for one.

Optional - Install Radiance

If you want to be able to use Radiance for daylighting simulations, you must install Radiance.

  1. Download and install Radiance 4.2.2.

Optional - Install Ruby

If you plan to use the OpenStudio SDK Ruby bindings via command prompt on Windows, you must install Ruby. OS X already has Ruby installed.

  1. Download the Ruby 2.0.0 installer.

  2. Add C:\Ruby200\bin to the PATH environment variable. Detailed instructions.

  3. Create a text file called with the following text inside:

    require 'C:\Program Files (x86)\OpenStudio 1.6.0\Ruby\openstudio.rb'

  4. Save the file as openstudio.rb here: C:\Ruby200\lib\ruby\site_ruby\openstudio.rb (next to the 2.0.0 folder).
