NC-2009 IEQp2:Environmental Tobacco Smoke (ETS) Control

Alternative compliance with ETS prohibition

We would like to certify a multifamily Residential building. Smoking will be prohibited within the LEED Boundary in common areas, but in some public areas (closer than 25 feet from main entrance) we cannot prohibit smoking because this would contrast local regulations. The owner doesn't want to prohibit smoking on private balconies (for commercial needs), but most of balconies are closer than 25 feet from operable windows. The apartments are equipped of mechanical ventilation system (the air intake is on roof, far from any ETS source) which will be working 24H/24 to renew inside air. Entrance doors will be equipped with self-closing mechanisms, in order to guarantee that outdoor smoke will be kept out. External windows are equipped with sealings which guarantee air tightness. Blower door tests will be performed according to the Protocol. Are these systems sufficient to comply with prerequisite requirements?

Based on your description, I would say no. Self-closing doors do not negate the 25' requirement. Nor do local standards. It sounds like this is a smoking building, but the other requirements still apply (as noted under Option 2 case 2).
