Tyler- I don't have access to my reference guide at the moment to check the exact language, but the intent of the credit is certainly to provide 14,000 cubic feet for each individual square foot of space, not an aggregate. Depending on how your systems are set up, though, you may be able to use an adjacent system to supplement the area that would have a long flush out time.

Thanks Allison. I agree with you that the it makes sense to count the building on a space by space basis, but there is no indication that this is how the credit is calculated in the reference guide. Furthermore, the equations and calculations that are provided are based on the building in aggregate. We are planning on supplementing our smaller systems with temporary fans and any other strategies to achieve this on a space by space basis, but it appears this level of detail was not addressed in this version of the reference guide. Thanks.
