Hi,
  I am learning how to model natural ventilation,but somes parameters make me puzzled,as follows,AirflowNetwork:MultiZone:WindPressureCoefficientValues, AirflowNetwork:MultiZone:WindPressureCoefficientValues.
Here is a idf file listed in examplefile.

Can you tell me how I can get these cofficient values in different cities correctly.
