Solar Access

You can use Insight Lighting Analysis to study solar access, or hours of direct sun over a given day by selecting the Solar Access study type. Requirements like SEPP 65 can be tested and validated using the Solar Access workflow.

To conduct this studies, follow the steps outlined in the Overview and take note of the following.

Solar Access studies are conducted for a day and selected time range, with several customizable settings.

A. Select the date and time range for the study. For all hours selected, the Direct Normal Irradiance (DNI) and Global Horizontal Irradiance (GHI) will be set to 1000 W/m2, and the Diffuse Horizontal Irradiance (DHI) will be set to 1 W/m2. Solar Access automatically uses the CIE Clear Sky model.

B. Set the minimum number of hours that will be required to have direct solar access and analysis plane height. In order to meet the minimum threshold, any point in the room must exceed 4000 lux.

The results summary will use the threshold you specified to calculate the percentage of passing rooms and produce in context results and a corresponding schedule.
