M1507.1 General. Where local exhaust or whole-house mechanical ventilation is provided, the equipment shall be designed in accordance with this section.
M1507.2 Recirculation of air. Exhaust air from bathrooms and toilet rooms shall not be recirculated within a residence or to another dwelling unit and shall be exhausted directly to the outdoors. Exhaust air from bathrooms and toilet rooms shall not discharge into an attic, crawl space or other areas inside the building.
M1507.3 Whole-house mechanical ventilation system. Whole-house mechanical ventilation systems shall be designed in accordance with Sections M1507.3.1 through M1507.3.3.
M1507.3.1 System design. The whole-house ventilation system shall consist of one or more supply or exhaust fans, or a combination of such, and associated ducts and controls. Local exhaust or supply fans are permitted to serve as such a system. Outdoor air ducts connected to the return side of an air handler shall be considered to provide supply ventilation. M1507.3.2 System controls. The whole-house mechanical ventilation system shall be provided with controls that enable manual override. M1507.3.3 Mechanical ventilation rate. The whole-house mechanical ventilation system shall provide outdoor air at a continuous rate of not less than that determined in accordance with Table M1507.3.3(1).
Before 1968, the New York City Building Code permitted air within hallways to be exhausted, so in a 1920s building, the hallway exhaust fans are competing with the exhaust fans in the apartment bathrooms and kitchens. If the exhaust fans in the apartments are stronger than the ones in the hallways, the stack effect will be exacerbated, drawing in odors (and in case of a fire, smoke) from the corridors into apartments. To alleviate the stack effect, an air-supply system can be installed in the hallways to deliver outside air into the building, providing positive air pressure in the hallways. (Heating and cooling coils would be required for the new air-supply fan system to temper the outside air supply.)
