An Air Wall is a feature that enables air exchange (0.35 ACH) between two Zones to be accounted for within a model. This could be for a perimeter Zone in an open office or an opening in a wall between two Zones.
Add an Air Wall by selecting the aspect to be determined as an air Air Wall. Select 'Select Wall' and then 'Air Wall'.
Note: Air Walls can only be applied between Zones with the same conditioning profile. For example, they can be used between two conditioned Zones but not between a conditioned and unconditioned zone.
