[EnergyPlus_Support] airflow and pressure : vertical channel (30x30cm)



I am trying to simulate a building with a vertical channel (like a 
chimney but without a heat source) to improve natural ventilation. The 
airflow through this channel is driven by temperature differences and 
wind pressure differences. I have added a crack in the roof surface to 
model this channel. I have a question concerning the pressures 
calculated by E+.
A formula I found in the E+ reference (linkage-model) : pressure 
difference = Pn - Pm + Ps + Pw. 
I take into account the wind pressure differences by 
using "SurfaceAverageCalculation" to calculate wind pressure 
coefficients.
But does E+ take into account the pressure difference due to the 
temperature difference in the channel?

Thanks
