Re: [EnergyPlus_Support] Site wind conditions

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

You can report "Wind Pressure" in [Pa] for each COMIS surface.  There are no 
other wind report variables except the "Wind Speed" from the weather file.

My understanding of the reference heights is that the "Reference Height of the 
Recorded Data" in the section "Comis Simulation", is as you suggest, this value 
is the height of the instrument above the ground independently of the altitude 
of the station.

In the COMIS CP Array object, the "Reference Height for CP Data" value is 
compared to the above height for the recorded data and the local wind speed at 
the building is adjusted accordingly.
