NC-2009 IEQp1:Minimum IAQ Performance

regularly occupied zones

Do we need to include spaces such as corridors, store rooms when computing the outdoor air requirement using the 62MZCalc ? Or do we include only regularly occupied zones in the calculation? Please advice.

Dear Stella, You can find answer at IEQ space matrix http://www.usgbc.org/resources/eq-space-type-matrix . Storage rooms without permanent working places are considered unoccupied. Egress stairway or dedicated emergency exit corridor are considered unoccupied, otherwise it must be ventilated according to table 6-1 of AHRAE 62.1.
