To minimize the exposure of building occupants to indoor air pollutants by preventing the transfer of air between units.
Perform a compartmentalization blower door testA blower door test gives an overall value for airtightness of a space, and can help identify air leaks. The testing unit consists of a calibrated fan that is sealed onto the unit entrance. The fan creates a continuous flow of pressure into the unit (or out of the unit when using theatrical fog to locate leaks). Devices detect the rate of pressure retention and loss due to possible air leaks in the construction. according to RESNET or the ENERGY STAR testing and verification protocols for multifamily midrise buildings, with an allowable maximum leakage of 0.15 cfm50 per square foot (0.04 cmm50 per square meter) of enclosure The exterior plus semi-exterior portions of the building. Exterior consists of the elements of a building that separate conditioned spaces from the outside (i.e., the wall assembly). Semiexterior consists of the elements of a building that separate conditioned space from unconditioned space or that encloses semi-heated space through which thermal energy may be transferred to or from the exterior or conditioned or unconditioned spaces (e.g., attic, crawl space, basement).(i.e., all surfaces enclosing the apartment, including exterior and party walls, floors, and ceiling).
