ASHRAE Guideline 44-2024
Protecting Building Occupants from Smoke During Wildfire and Prescribed Burn Events
Recommends building measures to minimize occupant health impacts from wildfire and prescribed burn smoke events. Applies to commercial buildings; institutional buildings, including health care facilities; and multiunit residential buildings, as well as dedicated spaces within these building types intended for temporary human occupancy during a wildfire or prescribed burn smoke event. Addresses buildings expected to be occupied by potentially at-risk populations, including children and older adults. Provides recommendations related to the design, installation, commissioning, operation, and maintenance of building envelope, ventilation, and air-cleaning systems. This guideline and its measures do not apply to internally generated smoke (e.g., from internal fires or structure fires). Dual units of measurement.
