Dear eQuesters

Does anyone know if solar heat gain will be recognized through interior
windows? I have a series of perimeter spaces with both exterior and
interior windows. The interior windows open into a double story atrium
that has windows and louvers at the top for passive ventilation.

I am currently modeling the atrium as an unconditioned space with
packaged VAVs on the perimeter zones. Does anyone have any suggestions
as to how I could best simulate passive ventilation? We have a TAS
model but I don't believe TAS is on the list of qualified software for
LEED EAc1. My approach right now is to tweak the equest model until it
matches results from the TAS model.

Thanks in advance for your advice!
