We have a project that has a two story atrium, running across the 1st and 2nd floor. Is the 2nd floor atrium (empty) space included in the gross area calculations or not?

I would like to check if the Carrier model 30RQ0262 (COPc=2,62 according ARHI test 550/590 despite ASHRAE requires ARI 340/360) will meet that Mandatory Provisions in terms of Equipment Efficiency.
