Inquiry

This project will be a complete renovation of a historic manufacturing facility into a multifamily facility. The owner plans to allow smoking in individual apartment units, but not in common areas or near the building. The following precautions will be taken to control ETS migration: 1. Signage will be provided in all common areas prohibiting smoking in them and also within 25 feet of the outside of the building. Owner will provide a letter indicating this is a policy that will be enforced. 2. Each apartment unit will have a dedicated furnace with split direct-expansion unit. Furnaces will be located inside the apartment they serve and wall penetrations for natural gas and refrigerant will be sealed air-tight. 3. To provide ventilation in bedrooms without windows, outdoor air will be pretreated by a dedicated outdoor air unit (or units) running 24/7, ducted through common areas, and delivered to all apartments in sufficient quantities to comply with Sections 4 through 7 of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 62.1-2004. Outdoor air ducts entering apartments from common areas will be sealed and gravity backdraft dampered to prevent contamination. 4. Rooftop makeup air units will condition outdoor air and maintain 0.02 inches of water column positive pressure in the corridors and atrium with static pressure control. 5. All penetrations through walls, ceiling, and floors between apartments, between apartments and corridors, and between apartments and adjacent rooms/shafts will be sealed air-tight. 6. All doorways between apartments and corridors will be weather-stripped. 7. After construction, blower door tests will be conducted by an independent party. Test will be conducted in accordance with American National Standards Institute (ANSI)/American Society for Testing and Materials (ASTM) -E779-03 and using the progressive sampling methodology defined in Chapter 4 of the Residential Manual for Compliance with California\'s 2001 Energy Efficiency Standards. Apartment units must demonstrate a leakage area less than 1.25 square inches per 100 square feet of enclosure. Will these measures meet the requirements of ETS control for LEED certification?
