Our project building has 5 AHU systems; 4 of them significantly exceed ASHRAE (200%, 130%, 363%, 41%). The building is a laboratory and has very stringent requirements for OA delivery and IAQ. One AHU, however, only exceeds ASHRAE by 16%. This fifth unit is a small split system that only serves the building's gym room, which is not typically occupied and represents a very small percentage of overall building square footage (less than 5% of total building square footage). The unit is incapable of exceeding ASHRAE by 30%. It seems like a stretch but is it possible to use the 10% SF exemption on this credit to exclude the gym, and thus not count the AHU that is disqualifying us from achieving this credit? Thanks!
