Requirements concerning multifamily residential dwellings, environmental tobacco smoke (ETS), and operations and maintenance are among changes to ASHRAE’s indoor-air-quality standard.
The newly published ANSI/ASHRAE Standard 62.1-2016, Ventilation for Acceptable Indoor Air Quality, sets minimum ventilation rates and other requirements for commercial and institutional buildings.
“The latest version of Standard 62.1 contains changes that affect high-rise residential spaces, the indoor-air-quality procedure, laboratory exhaust, and demand-control ventilation,” Hoy Bohanon, chair of the Standard 62.1 committee, said. “Designers and users of the standards who are involved with those spaces or processes will benefit from using the up-to-date requirements.”
Multifamily-residential-dwelling spaces have been removed from the standard and now are covered under ANSI/ASHRAE Standard 62.2, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings, Bohanon said. Areas outside of the dwelling space, such as corridors, lobbies, fitness rooms, and retail, remain covered by Standard 62.1.
Other major changes include:
- Revision of the definition of ETS to include emissions from electronic smoking devices and from the smoking of cannabis.
- Revision of operations-and-maintenance requirements to more closely align with the requirements in ASHRAE/ACCA Standard 180-2012, Standard Practice for Inspection and Maintenance of Commercial-Building HVAC Systems.
- The addition of requirements for determining minimum ventilation rates by considering the combined effects of multiple contaminants of concern on individual organ systems.
The cost of Standard 62.1-2016 is $84 for ASHRAE members and $99 for non-members. Copies can be ordered by phone at 1-800-527-4723 (United States and Canada) or 404-636-8400, by fax at 678-539-2129, or online at www.ashrae.org/bookstore.
