Installation Notes

OpenStudio is supported on Windows 7 – 10, OS X 10.9 – 10.10, and 64-bit Ubuntu 14.04.

Users should be aware that SketchUp no longer automatically enables the OpenStudio extension. To use SketchUp 2016 with OpenStudio, launch SketchUp and navigate to Preferences->Extensions to enable OpenStudio. After making this selection, OpenStudio will appear under Extensions in the menu bar.

OpenStudio 1.10.0 supports EnergyPlus Release 8.4.0, which is bundled with the OpenStudio installer. It is no longer necessary to download and install EnergyPlus separately. However, an installer is available at https://github.com/NREL/EnergyPlus/releases/tag/v8.4.0. Other builds of EnergyPlus 8.4 are not supported by OpenStudio 1.10.0.

OpenStudio 1.10.0 supports Radiance 5.0.a.5, which is bundled with the OpenStudio installer. It is no longer necessary to download and install Radiance separately. However, an installer is available at https://github.com/NREL/Radiance/releases/tag/5.0.a.5. Other builds of Radiance are not supported by OpenStudio 1.10.0.

Installation Steps

  • The OpenStudio SketchUp Plug-in requires SketchUp 2016 (not available for Linux). The OpenStudio SketchUp Plug-in does not support older versions of SketchUp. SketchUp 2016 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 2016, and the 64-bit version of OpenStudio will only work with the 64-bit version of SketchUp 2016.
    • If the OpenStudio Plug-in does not automatically load in SketchUp, open the Window->Preferences->Extensions window in SketchUp and enable the OpenStudio plug-in if it is listed.
  • Download and install OpenStudio.
  • Setup a Building Component Library (BCL) account to access online building components and measures. View instructions on how to setup your account and configure the key in OpenStudio.

Overview

OpenStudio 1.10.0 has a number of new features and bug fixes. Some of the more noteworthy are as follows:

  • Added ElectricLoadCenterDistribution, ElectricLoadCenterInverterLookUpTable, ElectricLoadCenterInverterSimple, GeneratorPhotovoltaic, PhotovoltaicPerformanceEquivalentOneDiode, and PhotovoltaicPerformanceSimple to Model API.
  • Updated plug-in to work with SketchUp 2016. SketchUp autosave will no longer save the osm. Surfaces referencing constructions with no layers are no longer shown as air walls in the plug-in.
  • Fixed code in Date and Time classes that resulted in memory access violation crashes in Ruby bindings.
  • Changed operation of ConstructionBase.getNetArea, see documentation for details.
  • Deprecated field 'Source Zone Infiltration Treatment' from object ZoneAirMassFlowConservation, adding E+ 8.4 fields 'Infiltration Balancing Method' and 'Infiltration Balancing Zones'.
  • The Radiance Daylighting Measure has the following additions:
    • Added support for electrochromic glazing (two-state)
    • Renderings are generated for each primary daylighting control point and glare sensor found in the model
    • Added ability to optionally generate "debug" images showing each window group octree
  • Made minor enhancements to standard OpenStudio simulation results.
  • Added water to water heat pump component models, including HeatPumpWaterToWaterEquationFitCooling and HeatPumpWaterToWaterEquationFitHeating.
  • Added capability to assign DesignSpecificationOutdoorAir object directly on VAV air terminals, including AirTerminalSingleDuctVAVReheat and AirTerminalSingleDuctVAVNoReheat. This is an EnergyPlus feature that allows for more precise outdoor air control, but was previously not available in OpenStudio.
  • Refined GridView elements in the OpenStudio Application to increase their performance.
  • Extended OSGridController and SpacesLoadsGridView to show loads inherited from SpaceTypes, and more generally, inherited subrows.

OpenStudio 1.10.0 includes several other minor features as well as many bug fixes. For a full list of changes included in OpenStudio 1.10.0 please see the complete changelog.
