Exporting to gbXML

To perform energy analysis using other software, export the model to gbXML.

Revit offers 2 methods for exporting to gbXML:

• Use energy settings: This method exports the energy analytical model created by Revit.

  The energy analytical model is composed of analytical spaces and analytical surfaces, which are created based on parameters defined in the Energy Settings dialog. The exported data provides an accurate energy model for analysis. Before using this method, define parameters in the Energy Settings dialog and create an energy analytical model.

• Use room/space volumes: This method uses volumes defined in the building model based on rooms or spaces in the model. These volumes may not be as accurate as those created using energy settings. Before using this method, add rooms or spaces to the model.

  The resulting gbXML file contains energy information for the model according to the gbXML file structure, which is based on a gbXML schema. The gbXML schema was created to help building designers get information about the energy consumption characteristics of their building projects.
