Installation Notes

OpenStudio is supported on Windows 7 – 8.1, OS X 10.9, and 64-bit Ubuntu 14.04.
OpenStudio 1.5.0 supports EnergyPlus Release 8.1.

Installation Steps

• Download and install EnergyPlus 8.1.
  • Download EnergyPlus 8.1. Create an account and login if you don't already have one.
  • OpenStudio will work with 32 or 64bit EnergyPlus installers.
• The OpenStudio SketchUp Plug-in requires Sketchup 2014 (not available for Linux). Older versions are not supported.
• Create an OpenStudio account, then 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.

Optional Installation Steps

• For Radiance integration, download and install Radiance.

Overview

This OpenStudio 1.5.0 release updates many OpenStudio dependencies. The biggest of these is an upgrade from Ruby 1.8 to Ruby 2.0. This update allows OpenStudio to leverage upon the improvements available in Ruby 2.0, and provides compatibility with SketchUp 2014. However, this update also means that OpenStudio will no longer be compatible with SketchUp 2013 or SketchUp 8. C++ developers will notice upgrades to Qt 5 and Boost 1.55, as well as the inclusion of C++11 features in OpenStudio source code.

OpenStudio for OS X is now built with the 10.9 SDK for Ruby 2.0 support, making Mavericks the primary Apple platform, and Ubuntu 12 support has been removed in favor of Ubuntu 14.04 LTS. Windows platform support remains the same, with Windows 7 – 8.1 compatibility.

This OpenStudio 1.5.0 release also includes several improvements to measures. Reporting measures can now request output variables from EnergyPlus to ensure that they have the data they need to create plots or make reports. Additionally, units and descriptions can now be added to measure arguments.

The OpenStudio C++ SDK documentation has been significantly improved, which includes a search feature and links between all Doxygen directories. Updated C++ and Ruby coding standards can be found on the GitHub wiki.

Other notable improvements:

• Previously available for Refrigeration Walk Ins and Refrigeration Cases, GridView (a grid-style interface providing detailed component views) has now been applied to the Space Types tab, as well as the Thermal Zones tab. These GridView-enabled tabs now allow practitioners to view and modify numerous Space Types (or Thermal Zones) and their objects, simultaneously.
• Multiple performance improvements and bug fixes.

Known Issues

The following are issues known at the time of publication of these release notes. Please contact [email protected] if you require further assistance.

Known Issues Common to All Platforms

OpenStudio SketchUp Plug-in

• If you use copy multiple on group-level OpenStudio objects, you will get one extra copy. The extra group is created by the first copy-and-paste operation and is not removed when the copy multiple occurs. To address this, after you perform a copy multiple procedure on groups or spaces, press delete. The objects you need to delete should already be selected. If you are copying loose surfaces such as windows, there are no problems, as SketchUp will merge equivalent surfaces. [issue #28]
• Using SketchUp's undo operation on OpenStudio model elements may produce unexpected results. [issues #54 and #150]
• SKP and OSM link is not maintained when files are relocated. However, you can manually re-establish that link. When opening a SketchUp file, launch SketchUp and then open the SketchUp file. If that doesn't work you can also directly load the OSM file, bypassing the SKP file. [issue #409]
• It is possible for the OpenStudio plug-in to conflict with other SketchUp plug-ins. If you suspect this is a problem, try testing with other plug-ins disabled, or contact [email protected] for assistance. [issue #26]
• Using "Intersect" in the surface matching dialog can result in a crash or unexpected results. This is more common with models that were imported from other CAD formats at some point in the workflow. It is a good idea to save prior to using this to avoid any loss of data. This is related to an underlying SketchUp bug. [issue #168]
• "Project Loose Geometry" can crash SketchUp. It is a good idea to save prior to using this to avoid any loss of data. [issue #484]
• Adjacent stacked spaces in same zones may result in incorrect area and likely loads as well. [issue #561]
• SaveAs in SketchUp corrupts measures in model. To avoid this, only add measures into model after work in SketchUp is done. [issue #754]
• Using AutoSave in SketchUp can overwrite changes made in OS app if the file is open in both locations. [issue #899]

If your OpenStudio model crashes SketchUp or has unexpected behavior please forward it to [email protected] with a description of the problem. Please also include the directory that has the same name as the OSM file. You can attach it as a zip file.

OpenStudio Application

• Similar thermostats assigned in the SketchUp Plug-in are shared across thermal zones in the OpenStudio application. Changing or turning off one will do the same to others. [issue #123]
• The view does not always refresh correctly when you delete a material from a construction. If you still see a material after clicking the "x", switch away from and back to the object to refresh the view. [issue #196]
• OS App Schedule Editor allo...
