Inquiry

Please provide clarification regarding EQ prerequisite 2, and the credit interpretation ruling dated 12-3-2003. The condos in one of the buildings on our campus are served by elevators and stairwells that open directly into the residential units. These elevators and stairs are not pressurized, but are required to resist the passage of smoke and fire as prescribed by the building code. The elevator doors have a UL approved brush system to prevent the passage of smoke, and the stair doors are equipped with smoke seals as well. Based on our compliance with the fire and smoke proofing requirements for these doors, it is our position (and the code requirement) that tobacco smoke cannot migrate from one unit to the next. How do you recommend that we document this compliance? Would weather-stripping and air leakage testing in compliance with E779-99 be adequate to document the LEED point? Is pressurization only required when weather-stripping is not provided?
