Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES 55
PRIORITY ISSUE 20.0 NATURAL (NOT FAN-POWERED) VENTILATION (continued)
ASSESSMENT PROTOCOLS (AP) MINIMUM ACTIONS (MA) EXPANDED ACTIONS (EA)
• Ensure ventilation openings
for introducing outdoor air into
dwelling units are located a
minimum distance of 10 feet from
contaminant sources including
plumbing stacks, vents, exhaust
hood discharges or vehicle exhaust
(see ASHRAE Standard 62.2-2013).
MA 20.2 Repair, Adjust and Upgrade
Ventilation Systems in Common
Corridors and Nonresidential Spaces As
Needed
Ensure common corridors in the
building meet the ASHRAE Standard
62.1-2013 minimum outdoor air
ventilation rate requirement of 0.06 cfm
per square foot of floor area.
If included in the scope of service,
ensure nonresidential spaces in
the building meet the ventilation
requirements of ASHRAE Standard
62.1-2013.
If it is not possible to achieve the
ASHRAE Standard 62.1-2013
minimum outdoor air ventilation rates,
adjust systems to provide the maximum
amount of outdoor air ventilation
possible.
• Air-cleaning devices that remove
ozone must be provided and used in
areas that are in "nonattainment"
with the National Ambient Air
Quality Standard for ozone. The
ozone removal efficiency of the
system shall be at least 40%.
