It is not clear to me how to model the "minimum outdoor air ventilation rates". If we intend to obtain the increased ventilation credit IEQc2, with at least a 30% increase above 62.1-2007, do these same rates need to be modeled in both the Baseline and Proposed cases? For example, lets say that a space will require 200 cfm of OA per 62.1-2007. To obtain IEQc2, we will provide 260 CFM of OA. Do we model this amount for both the proposed and baseline cases? If so, this "minimum outdoor air" as it is referred to in most areas of the LEED documents is not really the minimum as required by 62.1, but 30% higher, hence my confusion.
