[EnergyPlus_Support] Re: Natural ventilation by using Wind and stack area method?

["ujjwal.mnit@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

While working on a Energy Plus 8.4 model, Windandstackopenarea module was used for introducing natural ventilation in house.

The average value of Air Change per Hour  for  a 3X3X3 m^3 house with 2 windows(east and north) of 0.8 m^2 each came to be  43.67 

This is too much to analyse effect of a solar chimney ventilation under natural ventilation. I want to reduce it under practical limits.

After going through the algorithm from source code, it was found that coefficient of wind is taken from 0.55 to 0.3 for relative angles 0 to 180 of wind and window normal with linear interpolation

What should be the range of values for Coefficient of wind to be used for above model if i dont want to use auto calculate?
