Re: [EnergyPlus_Support] Shading calculations
FYI.
There were some technical papers on this concept at the ASHRAE meeting in Kansas City.

Subject: [EnergyPlus_Support] Shading calculations
Dear All,
Does anyone know how the calculations are made in EnergyPlus for an air gap
between a window and exterior shading device. I see this reference to standard
ISO 15099 (I am looking at the final draft) but when looking at the standard,
it says to assume a forced convection model and says to calculate the airflow
rate by using an experiment or CFD. But in EnergyPlus, there are various
inputs (side permuability, etc) that seem to indicate that it is using some
sort of model not described by the standard. I have the source code, so if
someone could kindly point me to correct subroutine or provide a reference for
this calculation, I would be most greatful!
Many thanks in advance.
