Hi folks,

I am simulating a 24-floor building to be LEED certified. The software is
Equest. In order to achieve as many points as possible in EA CR1,
demand-controlled ventilation (DCV) has been modeled in the proposed design.
But we are not sure if this stragety needs Exception Calculation Method
requested by USGBC. In one of CIR historical archive of LEED online, USGBC
requested exceptional calculation method for schedule-based DCV models. I
have no idea if USGBC would treat DCV models in Equest as those of

The use or removal of DCV will decisively impact the achieveable points of
EA CR1. I am wondering if anyone in this community has clear picture on this

Thanks in advance.
