I follow EnergyPlus and Openstudio Legacy plugin since two year, i have seen the publication of the Openstudio Legacy plugin 1.0.14 release in the Github page for the EnergyPlus 8.4 version. I want to ask you a few questions:

  1. Some time has pass since EnergyPlus 8.5 release, do you know when there will be a release of 1.0.15 Openstudio Legacy plugin for EnergyPlus 8.5 version?

  2. What are the disadvantages of the idf done with Openstudio Legacy 1.0.14 plugin and run with the EnergyPlus 8.5?

Big Ladder has agreed to become the new maintainer of the Legacy OpenStudio plugin. We plan to put out our first release in late August to September. This release will update the plugin for EnergyPlus 8.5 and address at least one critical bug (the double-creation of surfaces issue). The updated plugin will be coming out under a new name so keep on eye on the mailing lists for an announcement.

As for question number two, there are no significant disadvantages that I know of using version 1.0.14 of the Legacy plugin with EnergyPlus 8.5. The plugin will put up a warning message complaining that the plugin is for version 8.4 and might not be compatible. This warning is displayed when you first open an input file that is set to version 8.5, when you set the EnergyPlus engine in the Preferences window, and when you try to run a simulation (and possibly other times). As long as you persevere and don't let it discourage you, it will work. There are no changes in geometry objects between version 8.4 and 8.5 that would affect the way the plugin works.

@dradair We released our updated version of the Legacy OpenStudio plugin last week. To avoid confusion with previous versions (and "regular" OpenStudio), the new/updated plugin will be now be called Euclid. For more information, and to download the latest version, visit our Euclid project page here: The plugin has been updated for EnergyPlus 8.6 and 8.7 and has been fixed to work with more recent versions of SketchUp (2015-2017). The double-creation of surfaces issue has also been fixed.

I think the near-term answer to your first question is in the discussion on this issue on GitHub:

I can't speak to your second question, maybe others can.
