NC-2009 IEQp1: Minimum IAQ Performance
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!

Is outdoor air quality testing required in a space using natural ventilation?
What options are available to projects outside the US to meet this prerequisite?
Can LEED 2009 projects elect to follow ASHRAE 62.1-2010 for this prerequisite?
Which units should be included in the calculations for this prerequisite?

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.
