The OpenStudio application maintained by the OpenStudio Coalition includes an option to export to gbXML.

gbXML is the universal schema to transfer models between various analysis engines and software. For more information on gbXML check out this article.

An OpenStudio file, or .osm can be exported from both the Baseline analysis and loadmodeling.tool. Once exported the model can be opened, viewed, edited, and exported from the OpenStudio application.

Note: Exporting the Building Analysis Model from loadmodeling.tool will provide the gbXML file directly!

To export a gbXML file from OpenStudio follow these simple steps:

  1. Open the .osm file in OpenStudio

    1. [optional] view the model by going to the geometry viewer (6th tab)

  2. Navigate to File -> Export -> gbXML

  3. enter the desired file name and location and hit save!

  4. Your gbXML file is now ready to be imported into any building simulation platform!

For a full list of software that can import a gbXML file see here.

Once exported follow the guidance for gbXML import for the platform you need to open the model in. These are typically as simple as File -> Import gbXML!
