Hello everybody,

I am trying to use Radiance to create the solar incidence values for the surface, and then fed in to EnergyPlus for simulation like previous question. link text

There's no problem in creating the schedule file, and I used SurfaceProperty:SolarIncidentInside object to calculate solar distribution. It seems that SolarIncidentInside object does not affect the diffuse solar radiation transmitted through the zone’s exterior windows, but it can be dealt with by setting the solar radiation absorption rate to 1 and subtracting that from the schedule.

But the problem I am facing is that I cannot figure out how to schedule inside face of the window with the solar gains. Using SurfaceProperty:SolarIncidentInside object, all the building surface can be scheduled with the solar gains, but it seems that Fenestration Surface can't.

(Although the amount of solar radiation (1) absorbed in the glass of the zone’s exterior and interior windows and (2) transmitted back out of the exterior windows is quite small, and the influence on room temperature is extremely small)

Does anyone know? Thank you in advance.
