Daylight Factor: No influence of tvis?


I am doing daylight calculations with different window types, which i construct myself. However, changing tvis doesn’t seem to change the daylight factor result. Has anyone of you encountered this issue? Attached you can find a screenshot of the script and the file itself.

Moreover: Is there the possibility to change the reflectance of surfaces?

Thank you for any advice!

Hi @TonyMa,
Constructions are only used for energy simulations. For effecting daylight you will need to define a modifier set.
