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?

I would say that you'd be tying yourself (and your GBCI reviewer) in knots unecessarily if you referenced 2007 in the credit and 2010 in the prereq. Not sure that it would be prohibited, but the documentation is related, so I wouldn't mess with it.

Since USGBC requires that when you use an ASHRAE addendum, it must be applied to all credits, I would imagine they would also say that the application of an entire standard would need to be consistent amongs all credits.
