DIVI Daylight Problem

I've been having some issues getting reasonable results from DIVA's Daylight Factor simulation. I've never used DIVA before, so I'm not sure what the problem is. But based on the color gradient showing the results, it's clearly not working. I've even tried rotating the form 90 degrees to see if it changes anything but it didn't.

Everything is internalized in the gh definition. Any help would be appreciated!
