Re: [EnergyPlus_Support] surface exterior wind speed

[Lixing Gu <gu@xxxxxxxxxxxx>]

The AirflowNetwork model calculates reference wind speed based on weather 
wind speed. The equation used in calculations is the second equation in the 
Engineering Reference on page 385. The boundary layer height is 60 m. The 
field value of Reference height for recorded wind data in the AirflowNetwork 
Simulation object is used as "Meteorological station height. If the input of 
Wind Pressure Coefficient Type in the AirflowNetwork Simulation object is 
"INPUT", the field value of Reference Height for WPC Data in the 
AIRFLOWNETWORK:MULTIZONE:WIND PRESSURE COEFFICIENT ARRAY object is used as 
the reference height. If the  input of Wind Pressure Coefficient Type in the 
AirflowNetwork Simulation object is "SURFACE-AVERAGE CALCULATION", the 
reference height is 10 m. Then wind pressure is calculated using the first 
equation in the section of "Wind pressure calculations" in the Engineering 
Reference on page 385. The wind pressure on each surface is applied in 
airflow calculations. Please see the last equation on page 380 in the 
Engineering Reference.
