Energy Analytical Model - No Analytical Spaces

Issue: Revit could not find analytical space that is necessary for energy simulation.

Solution: Simplify the complexity of the model. See Energy Analysis using Building Elements - Model Validation.

Solution: Add room bounding elements. See Room-Bounding Elements and Room Boundaries.

Solution: Check to ensure that building elements belong to the project phase set in the Detailed Model Settings in the Energy Settings dialog.

Solution: Check to ensure building elements form a generally enclosed shell. For example, there should be no missing walls, floors, roofs, windows, etc. See Energy Analysis using Building Elements - Model Validation.
