In some of our projects, we are providing outdoor air to some spaces which do not require outdoor air supply as per ASHRAE 62.1. For example, water tank room, some storages etc.
When showing these spaces in the IAQ Calculator, there is no suitable "Occupancy Category" to assign to these spaces since outdoor air is not required for these spaces.
Should these spaces be ignored in the IAQ Calculator as they are not required to demonstrate "Minimum Indoor Air Quality" pre-requisite? If they are ignored, the total FAHU supply air value will not match the value stated in the IAQ Calculator due to excluding these spaces.
