Perform a Daylight Potential Analysis

Use Forma daylight potential analysis to understand how much daylight reaches building façades from the sky to guide design decisions and check compliance with local guidelines.

Note: As a Forma Connected Client, Revit offers Forma capabilities that are part of a technology preview (tech preview), which means that it's new and continuously improving. Learn more.

Before starting an analysis, prepare the model to access Forma tools.

To perform a daylight potential analysis

1. Open a view where you will be able to see results of the analysis, such as a 3D view or an elevation view.
2. Click Analyze tab > Forma Analyses panel > (Daylight Potential).

   As an alternative, you can click (Analyses & History) and, for Run analysis, click Daylight Potential.

3. Review the results.

   In the view, Vertical Sky Component (VSC) results display as a heat map on visible supported elements. For more information, see About Forma Daylight Potential Analysis.

   The analysis updates whenever you make changes to the model. For example, change the size and shape of a building mass, and instantly see how the change affects daylight potential.

   When you switch to another view or Revit model while the panel is open, analysis results display for each.

4. To stop the analysis, close the Daylight Potential panel.
