Re: [EnergyPlus_Support] shading device(slat-type) perpendicular to building surface

["Michael J. Witte" <mjwitte@xxxxxxxx>]

1.  This would have to be constructed from a set of 
Surface:Shading:Detached:Building objects.

2.  Wind-driven airflow can be modeled one of two ways, with simple VENTILATION 
or INFILTRATION objects, or with the more complex AirFlowNetwork objects.  If 
you use the airflownetwork approach, you will need to set the window 
ventilation controls to force the window to be open at all times.  EnergyPlus 
will not be able to calculate the airflow resistance of the shading device.  
You will need some other way to determine the flow characteristics outside of 
EnergyPlus.
