Hi,
When modeling the increased outdoor air venitlaiton per IEQc2 in the proposed and baseline buildings in EAc1 for LEED CS v3 (2009), should the baseline and proposed buildings have the same outdoor air quantities? Or should the baseline be modeled at 100% and should the proposed be modeled at 130% if the building is going for IEQc2 Increased Ventilation? ASHRAE 90.1-2010 section G3.1.2.6 exception c requires that they be different if the proposed uses excess air per IEQc2, but I don't see anything in ASHRAE 90.1-2007 or in the LEED v3 credits that require they be different. Can you help me out with this? Thanks!
