We are considering locating a prefabricated smoking room on a building terrace (on the top floor of the building). The room meets the technical requirements for a smoking room located within the building (negative pressure, etc.) and filters the air before exhausting it to the outside. The exhaust will be "away from air intakes and building entry paths (and windows).

It seems to me that this should be compliant, however there will not be any smoking in the building and the location of the smokers within the smoking room will be within 25 feet of building windows and doors. A strict interpretation of the credit language could prevent us from achieving this prerequisite.

Does anyone have any experience or suggestions on how to proceed?
