ASHRAE-IAQ-standardUSA:  Requirements regarding multi-family dwellings, tobacco smoke, and operations and maintenance are among changes to ASHRAE’s indoor air quality standard.

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 is said to contain changes that affect high-rise residential spaces, the indoor air quality procedure, laboratory exhaust and demand control ventilation.

“Designers and users of the standards who are involved with those spaces or processes will benefit from using the up-to-date requirements,” said Hoy Bohanon, chair of the Standard 62.1 committee.

As with the 2016 version of Standard 62.2, Ventilation and Acceptable Indoor Air Quality in Residential Buildings, the scope of Standard 62.1 has changed. Multi-family residential dwelling spaces have been removed from the standard and now are covered under 62.2, according to Hoy Bohanon, chair of the Standard 62.1 committee. Spaces outside of the dwelling space such as corridors, lobbies, fitness rooms, retail, etc, remain covered by Standard 62.1.

The definition of “environmental tobacco smoke” has been revised to include emissions from electronic smoking devices and from smoking of cannabis.

In addition, operations and maintenance requirements have been revised 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 cost of Standard 62.1-2016, Ventilation for Acceptable Indoor Air Quality, is $84, ASHRAE members ($99, non-members). To order, visit www.ashrae.org/bookstore.
