NC-2009 IEQp1:Minimum IAQ Performance

Parking ventilation/exhaust

As per ASHRAE 62.1 parking areas are subject to requirements for exhaust air and not ventilation rates. Accordingly, parking areas are not included in IEQp1, are they? Thanks in advance!

IEQp1 in inclusive of the entire ASHRAE 62.1 Standard. You do not need to include parking garages in your 62MZ calculation, but you must design to the standard and account for the space. I always include a note that "xxxx" sf of space complies with Table 6-4 because it is "xxxx" type of space. This lets them know why your 62MZ calculated area does not equal the total building area.
