I am working on a CI project which is in a tall building. The building itself is not LEED certified and the air intakes of the building on 41st floor that provide air to the CI project do not have MERV 13 filters. The intent of this credit is, I believe, prevent hazardous particles that are typically from traffic and other activities surrounding the building that from entering the project space. Would this requirement be still enforced without an exception, even if physical circumstances almost guarantee that the fresh air is unlikely to be polluted at that height (41st floor)? Would it be worth writing a narrative describing that the intent of this credit is fulfilled with the existing filters?
