Add Thermal Properties to Building Elements for Energy Analysis

When you want to perform energy analysis for a Revit model that contains building elements such as floors, walls, and roofs, you can add thermal properties to the elements.

To include thermal properties for energy analysis

1. Open a view that displays the detailed building model.
2. Click Analyze tabEnergy Analysis panel Energy Settings.
3. Under Detailed Model, do the following:
   • For Export Category, select Rooms.
   • Select Include Thermal Properties.
Note: If thermal properties are not included in material element layers for elements in the model, the default Conceptual Constructions are used in the analysis. See About Rooms and Spaces for Energy Analysis and Conceptual Constructions.

To add thermal properties to elements

1. Open a view that displays the detailed building model.
2. Select a building element, such as a wall.
3. On the Properties palette, click Edit Type.
4. For Structure, select Edit.
5. In the Edit Assembly dialog, click in the Material column.
6. In the Material Browser, click + Thermal to view and edit thermal properties.
7. Click Apply and OK to close the dialog.
8. Click OK to close the Edit Assembly dialog.
9. In the Type Properties dialog, under Analytical Properties, note that the thermal properties are populated: Heat Transfer Coefficient (U), Thermal Resistance (R), and Thermal mass.
10. Repeat steps 2-9 for each element that requires thermal properties for energy analysis.
