Daylight Factor
for EN 17037
UK specificities

DL-Light calculates the Daylight Factor. DF is calculated and results are directly displayed within the 3D SketchUp model.

The European norm EN 17037 introduces new requirements and thresholds for the calculation of the Daylight Factor. DL-Light implements them and allows to directly calculate the compliance to the standard.


The United Kingdom has introduced several differences compared to the general EN 17037 norm. They are taken into account in this module, thresholds, types of spaces, etc
