I am trying to use 3 phase and 5 phase analysis for a simple box model with a window using a BSDF file. The output illuminance values seem to be very low for 3 and 5 phase method. I tried using the same HBobjects with Grid based- annual (without a BSDF file) in Honeybee[+] and it seems to work fine.
I also looked at some of the past posts about the window surface normal being important for 3/5 phase simulation method. I checked the surface normals and they seem to be pointing outwards for all the surfaces. Can somebody please suggest what might be going wrong here?
