Hi all,

I was wonderring if anyone knows what is the reference pressure for Air Change per Hour (ACH) under ZoneInfiltration:DesignFlowRate object.

More specifically, for AirChanges/Hour field, is the pressure difference based of 4 Pascals ACH or 50, ?

Thanks, Mohammad

The ACH should reflect expected pressure differences across the building envelope during normal occupation/operation (just like the 4x other "Design Flow Rate Calculation Methods"). So yes, closer to 4Pa (than 50Pa or 75Pa).
