Help needed with daylight analysis

hello everybody!

I wanted to create a daylight analysis for a simple geometry but I don’t get the analysis to run…
some of the triangular shapes in front should be windows, I wanted to try out different versions with the windows to see which works best for bringing light in the room… examples for the windows shown in the images.
would be great if somebody could help me with that! (520.9 KB) UE4.3dm (128.1 KB) (239.3 KB)

Thank you and kind regards,

Hi Monika - please visit the Ladybug tools forum for questions related to those tools:

the problem is i can’t upload anything there since i’m a new user…

Hi Monika - I don’t know how that site is configured but it shouldn’t take that much to get elevated rights. I think that, by default for Discourse forums, you need to have read at least 5 threads and have spent at least 10 minutes reading. You could start by reading the guidelines on that forum ( and then search for threads on daylight analysis. If all else fails, you can always put the files on Dropbox, OneDrive, GoogleDrive, … and link to them from your post - or just link to the files that you have posted here…
