The process that Autodesk Revit uses to create an Energy Analytical Model is finicky, and it can take a very long time (or stall completely) with very large complex models.
To work around this known limitation, follow these steps to create a simplified model to analyze, which removes elements that aren’t used by the analysis:
- Use File > Save As > Project to create a new local Revit project on your computer.
- Create a new 3D default view that shows the entire model.
- Remove all coordination models.
- Select any coordination models (for example, the context buildings).
- Unpin, then delete them.
- When this warning appears, click Remove Model.
- Remove the toposolid that represents the terrain.
- Select the toposolid element.
- Then, delete it.
