[EnergyPlus_Support] WPCs input in Airflow Network

["michele.rossi@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hello everyone,

 

I have a doubt about the calculation of Wind pressure coefficients (WPC) in the Airflow Network group in EnergyPlus (natural ventilation modeling) when I use INPUT as a choice of wind pressure coefficient Type.

I am using relative coordinate system and I intend to rotate my geometry for different orientations by changing the North Axis. So, I would like to know if the WPCs input is related to True North or Building North? Do I have to input different WPCs data for each orientation?

 

Thank you very much,

 

Michele Rossi
