[EnergyPlus_Support] Daylight - interior windows

["marziasedino" <marziasedino@xxxxxxxx>]

Dear all,

I am assessing daylight and glare within a simplified model of a 
building:
the real building is one big thermal zone, but as the building 
geometry is not regular I divided it into two thermal zones assigning 
the fake partition wall between them as an interior window.
As I want the interior window to behave as a hole, I assigned the 
glass the following properties:
- very low thickness
- low reflectance 
- high trasmittance 
- air conductivity

I used detailed daylight to assess lux levels and glare index within 
the two zones, but my outputs show that lux levels in the zone with 
only the interior windows are much higher than lux levels in the zone 
with the exterior windows, as if the fake glass were amplifying light.
As the problem is my fake window, do you know if there is a better 
way to model it, still keeping the division between the two zones?
I uploaded my file on the "Problem Submittals" folder. Its name 
is "daylight test".
thanks a lot

Marzia
