[EnergyPlus_Support] Vented PV Cavity

["lnttony" <lnttony@xxxxxxxxxxxx>]

Dear all,

I am modeling the building integrated photovolatic (BIPV) system for 
the building facade. The photovoltaic (PV) panels were attached on 
the exterior wall with an air cavity between them. I want the PV 
panels to serve as a solar heat barrier. But I have problem in the 
heat gain on the facade.

By using "OtherSideConditionsModel", I applied "Vented PV Cavity" as 
the type of modeling used to determine boundary conditions. 
The "SURFACE:HEATTRANSFER:EXTERIORNATURALVENTEDCAVITY" object is 
used to describe the condition. However, there is no heat gain 
reduction for the underlying surface (i.e the exterior wall), even 
the required cooling energy for the corresponding zone is higher.

Is there any mistake I have made? Or, is there any part I have to 
pay attention on?
I would be very happy if I can receive any kind advice and help.

Best Regards,
Tony LAM
