No Analytical Spaces
While preparing for an energy analysis, Revit could not find analytical spaces, which are necessary for energy simulation.
Insufficient Information for Energy Analysis
This error appears when the software is preparing to perform an energy analysis on a conceptual mass, but important information is missing from the model.
Links Not Room Bounding
To perform an energy analysis, you have selected Run Energy Simulation, but some linked models are not set to Room Bounding.
No Mass Floors
Energy analysis using conceptual masses cannot be performed unless the conceptual masses have mass floors.
No Visible Masses
Energy analysis using conceptual masses cannot be performed unless the 3D view displays one or more masses that have mass floors.
Unknown Location
When starting an energy analysis, the software cannot recognize the project location specified in the Location Weather and Site dialog.
Energy Model Contains Too Many Shades
When you perform an energy analysis on a building model, the energy model displays shade surfaces in unexpected places.
