Yes.  It’s for the expected airflow path through the facade, which could differ from the overall height of the cavity (hence the separate input).

 

But if the upper and lower joint openings aren’t equal, then the neutral pressure level might be shifted away from the midpoint.

When the external pane is open joints is better to considerer the half height between joints?

This is the height scale for buoyancy-driven ventilation.  It is usually the overall height of the cavity’s airflow path (in z-direction) divided by 2.

Hi,

 

Can anyone tell me how a can calculate the value of the height from midpoint of lower opening to the Neutral Pressure Level (ΔH_NPL) to input in the program ?

 

Thanks,

 

Catarina Carvalhal
