Basecase System selection

Dear All:- Our project is G+3 factory building and a floor area of 1,80,000 Sq.ft 80000 Sq.ft is A/c area and remaining areas are Ventilated by fresh air fans so we take system 06-System 6—Packaged VAV with PFP Boxes But the reviewer told "according to ASHRAE 90.1-2007 Table G3.1.1A, since the building is greater than 150,000 square feet, the Baseline system should be System 8: VAV with PFP boxes. Additionally, per G3.1.1, "for systems 5, 6, 7, and 8, each floor shall be modeled with a separate HVAC system." Confirm that the Baseline system was modeled correctly or revise the system type to reflect ASHRAE modeling protocol." As of now we think the area & no floor mentioned in ASHRAE is Conditioned area & floor having conditioned area (Greater then 150000 Sq.ft) 1.Is it correct 2To model the project with system 8 is required or not for our case 3.We are confused so please tell which system we consider in simulation 4.Please advise what we tell to reviewer if the system 06 is correct
