Users are encouraged to draw the project geometry in the native drawing.tool for the most seamless translation to OpenStudio.

Geometry imported using a plugin (Revit, Rhino/Grasshopper, SketchUp, etc.) will also work, however does require using drawing.tool to fully close the rooms. To do this go to drawing.tool after importing and verify the geometry is correct there before exporting to 3D analysis. If some rooms are not closed drawing.tool can be used for further cleanup.

Note: The OpenStudio is set up for single-use type buildings. If planning to export to OpenStudio please only set a single-use type on the Project page before continuing. Once in OpenStudio, each room of the building can be assigned a unique use type, allowing for full mixed-use and even more detailed modeling.

Switching to '3D Viewer' mode and hitting 'Export 3D Model' (shown in the image above) will transfer the project geometry onto the 3D analysis page.

Once the 3D analysis finishes, the user can proceed to the baseline page. The 'OpenStudio Export' button will start the process to generate the files for export.

Once the export is successful, the message displayed in the following image should be visible. After clicking on 'Download OSM file', the zip folder containing the essential files will be saved.

Troubleshooting tips:

  1. Make sure there are no overlapping windows/elements in the drawing tool.

  2. Try changing the system type to 'VAV w/reheat, with Gas Boiler and Water Cooled Chiller' and hit 'Recalculate' before re-exporting. Systems can be customized further in the OpenStudio application.
