Here is an interesting potential case I was asked about:
A company is considering pursuing LEED-CI for occupancy on the upper floors of a 10 story building. There is a ground floor night club on the premises that permits smoking, and the operating hours are after 6 pm and weekends (i.e. minimal if any occupants in the general areas of the building). If the club space is sealed well but NO local exhaust/negative pressure is provided, what are the odds that GBCI will rule favorably in a CIR? The key element is the after-hours operation of the club.
