In a project's IEQp1 we want to use a non-default value for occupancy of a Conference Room (a Critical Zone). My question is, can we use the 62MZ Calculator to show that that area has adequate OA supply per ASHRAE62, or would we need to model every zone in the Calculator if we use it?
Further, on the Template, if we do not check 'Default' for Occupancy (default is 50 ppl/1000 sf for Conference) and have designed the room to a 12 person Occupancy do we enter '12' or do we enter whatever 48 as that is what the Occupant Density/1000 square feet would be? Question is: If we use a non-default value, couldn't we just use 12 in the box? Or does that value have to be per 1000 sf?

Taylor, you can still use the 62MZ calculator with a non-default value. In the template, keep to consistent units (48). It would be helpful to submit a brief narrative to describe that you've used a non-default value.
