ASHRAE Proposes to Move All Residential IAQ Requirements
to Standard 62.2.
Dwelling units of multifamily buildings of any height
would fall under ASHRAE’s residential ventilation
standard, 62.2, under a proposed change designed to
provide consistency of ventilation requirements.
Currently, ANSI/ASHRAE Standard 62.1-2013, Ventilation
for Acceptable Indoor Air Quality, has responsibility
for multifamily residential buildings 4 stories or more,
while ANSI/ASHRAE Standard 62.2-2013, Ventilation and
Acceptable Indoor Air Quality in Low-Rise Residential
Buildings, has responsibility for residential buildings
3 stories and less.
“The Standards 62.1 and 62.2 committees are proposing
scope changes that would result in the dwelling units of
all multifamily buildings being covered by Standard
62.2,” Paul Francisco, chair of the Standard 62.2
committee, said. “Common areas would be covered by 62.1.
This will provide consistency of ventilation
requirements for dwelling units regardless of building
height. For new construction, this will result in a
change of requirements for dwelling units in 4+ story
buildings. For the retrofit market, this change will
result in coverage by ASHRAE ventilation standards for
the first time in 4+ story buildings.”
