[BLDG-SIM] Daylighting in eQUEST

I have personally never used eQUEST myself, but I know that Ramana Koti,
an MSc student from Arizona State University working with Marlin
Addison, recently carried out a comparison study of the DOE2.1 daylight
calculation engine and Daysim (Radiance-based) for which they imported
Daysim illuminance profiles directly into eQUEST. Ramana or Marlin can
probably share the details with you.

So, in case you have a 3-dimensional model of your building (e.g. in 3ds
or dxf) you can import it into Daysim and calculate the annual
illuminance profiles. You obviously have to use the same climate files
in both programs which should not be an issue since Daysim imports epw
files.

Does anyone have a good idea how to model daylighting for core spaces -
i.e. daylighting that has gone through interior windows or air-walls?
