The office building is being certified under EBOM v2009. The project team wants to substitute the prerequisite IEQp1 v2009 with EQp1 v4 and then achieve IEQc1.3 credit. The prerequisite EQp1 would have to be achieved using ASHRAE 2010. Question then is - based on which standard, ASHRAE 2010 or ASHRAE 2007, would the IEQc1.3 credit's requirement (30% ventilation rate increment) have to be satisfied?
