COLUMN IEQ APPLICATIONS
experience of air-handling units incapable of having
MERV 13 filters installed. Members of ASHRAE who have
looked at these " impossible " situations have regularly
found engineering solutions available without modifying
filter racks. These members and others serving or
consulting on the Standard 62.1 committee have been
discussing the topic of increasing minimum filtration
requirements or adding provisions for larger filters in
equipment design.
One of the constraints on a standard intended for
code adoption is that it must take into consideration
the availability of technology to meet the requirements
of the standard. A recent example of this limitation is
an addendum to Standard 170 in 2018, which reduced
filtration requirements for in-room recirculating units
because the proposed minimum filtration was not available
from the majority of the ventilation equipment
manufacturers. This is an area where government action
could compel manufacturers to make improvements to
their equipment that ASHRAE cannot compel. ASHRAE
recognizes the urgent need to update standards, but
there are limits to the speed with which consensus
standards can be developed and to the speed with
which manufacturers can respond to changing market
demands for new products.
A panelist shared a story about his own COVID infection.
The reason he gave for his infection is he did not
follow masking and social distancing guidance. The first
of ASHRAE's core recommendations is to follow public
heath guidance,5. Engineering controls are one part
of any risk reduction plan. The way to reduce risk is by
eliminating the source of risk; failing that, engineering
controls, administrative controls, and personal protective
equipment are necessary countermeasures.
Health-Based Ventilation Metrics
The November 2022 ASHRAE Journal IEQ Applications
column presented an argument for moving to a healthbased
standard.13 This is an active area of discussion
within the ASHRAE community and its committees.
In fact, ASHRAE has been discussing this topic prior
to COVID-19, most notably with the formation of a
Authority
