Good evening,

I am working on a daylight calculation and I want to collect the daylight factor and cross-check it against table A.3 of EN 17037.

How are the values Dm, Dmin and Dmax calculated by the software?

Following the standard's specification, a border strip of 0.5 meters along the walls must be excluded from consideration. The measurement grid must be every 0.3 meters and have a measurement point height of 0.85 meters.

The standard daylight factor grid seems slightly different. According to which standard is it calibrated?

Thank you
