Hello - I am working on a new construction VA Medical Center that has been designed using the ventilation rates in ASHRAE Standard 170-2008 as per the v4 NC-Healthcare. Can we still qualify for this prerequisite under NC BD+C, since we clearly meet the "minimum requirements" of 62.1? The difference is that we did not determine the minimum outdoor air intake flow using the 62.1 ventilation rate procedure. We used 170. We would prefer to use NC BD+C for this project. Thank you.
