For IEQ credit 5 in LEED 2009 "Indoor Chemical Source Control"
They require you to state what the average differential pressure is across a particular room.

ASHRAE lists a formula (Q=2610*A*√∆P) Which tells you the differential across a door, but does anyone know what LEED means when they require the average differential pressure and how to calculate it ?

Thanks for your help.
