Export the Following Properties
NB: Using Revit Spaces all the data list below can be exported, but Using Revit Rooms only data highlighted in Blue can be exported.
• Location • Building type• Constructions• Room Names• Room type – Occupied/Plenum• Occupancy – Heat Gain/Per Person• Electrical – Lighting Loads – Power Loads

Export Room Properties - Constructions
Make sure ‘Include Thermal Properties’ is ticked when exporting constructions from your Revit model utilising ROOMS placed within. If this is not selected analytical constructions will be exported.

The following checklists/tips are items that are necessary in your Revit model before the translation to a design /building performance model. The following pages of this document will describe in more detail each of these items. 1. Rooms (refer to Section 1.9 - Rooms)Make sure all rooms/spaces are place in every room, and adjacencies of Rooms are correct. 2. Room Bounding Elements (refer to Section 1.12)Check or uncheck room bounding elements that is necessary for design / building Performance model. For example, you can make shaft walls that are located on the exterior side of walls to be non-room bounding rather than placing a separate room into them. If an interior space has many ½ walls or jogs (that protrudes into but does not divide two spaces), these walls can often be made non-room bounding and leave a simple room perimeter to bound the space. Think about where you really need to take account of the walls for your type of analysis. 3. Define all Upper and Lower Boundary (refer to Section 1.14 - Defining the Upper & Lower Boundary) Make sure all the Upper and Lower Limits and Offsets are correct 4. Project Information (refer to Section 1.8 - Project Information)Make sure the Energy Data parameter in the Project Information is filled out correctly either in the plugin if you are using that for export or in Revit project information if you are using Revit to export. 5. Room Volume Computations (refer to Section 1.15 - Room Volume Computations)Make sure Room Volume Computations is checked

6. If it’s a central model, detach from central. Clean up views, elements that are not related to energy analysis (casework, railings, etc.), and purge unused. This will help reduce the size of the file. 7. Try to keep the model as lean as possible in Revit,This will be worth it when trying to run analysis and will impact runtime greatly. Only keep elements essential to the gbXML. Many firms have separate Revit construction document models and Revit analysis models, though in the future hopefully that will change. Simplicity of your model is paramount. 8. Run a model check once in the VE.

• Check What Revit is ExportingGo to File > Export gbXML > Details Tab > Select Analytical Surfaces option
• Check Rooms/Space fill the model
• Check the Levels they are set at
• Check Import/Export Settings
