CI-2009 IEQp1:Minimum IAQ Performance

System vs. Zone Compliance

Is it the system or the zone that must comply with the ventilation requirements? In May 2011 the USGBC updated the calculator for v2 projects (v3 doesn't appear to be updated) to check for compliance only at the system level... Our previous understanding was that each zone has to meet the thresholds for credit compliance (EQp1 = equal or better, EQc2 = 30% higher or better), but the new calculator only requests OA flow at the system level and then on a separate sheet only examines the system for compliance, not each individual zone.

My understanding of this is that each zone has to comply.
