Due to wide differences in personal comfort levels and
clothing influences, typically, up to 20% of people in a
space may be uncomfortable to some degree— so don't
expect to obtain 1 00% satisfaction. Also, occupant
discomfort may result from stressors such as
glare, noise, ergonomics, or job or home stress.

• Check ventilation and temperature control
for entire building
• Check outdoor air quality
• Review sources that are spread throughout
the building (e.g., cleaning materials or
microbiological growth inside the
ventilation system)
• Check for distribution of a source to
multiple locations through the ventilation
system
• Consider explanations other than air
contaminants
This Wheel provides an easy, step-by-step process for
';• identifying and solving common indoor air quality problems.
|lt is important that this Wheel be used in conjunction with
fjmore detailed guidance, as provided in either of the
publications noted below, which can be purchased from the
|US Government Printing Office by calling 202-512-1800.

>.Symptoms begin and/or are
'"worst at the start of the
*Joccupied period
• Review HVAC operating cycles.
Pollutants from building materials,
or from the HVAC system itself may
build up during unoccupied periods
Symptoms worsen over
'course of occupied period
• Consider that ventilation may not be
adequate to handle routine activities
or equipment operation within the
building, or thai temperature is not
properly controlled.
Intermittent. Symptoms
« Look for daily, weekly, or seasonal
cycles or weather-related patterns,
and check linkage to other events in
and around the school.
Check ventilation and temperature control
within the complaint area
Review pollutant sources affecting the
complaint area
Check local HVAC system components that
may be acting as sources or distributors of
pollutants
Consider spills, other unrepeated
events as sources.
Single event of symptoms
^individual rooms,
.- ;zones, or air handling
-'systems)
Ask staff and occupants to describe
recent changes or events (e.g.,
remodeling, renovation,
redecorating, HVAC system
adjustments, leaks, or spills).
Recent onset of symptoms
Building Air Quality: A Guide for Building
Owners and Facility Managers
S/N 055-000-00390-4
Check for drafts, radiant heat (gam or loss),
and other localized temperature control or
ventilation problems near the affected
individual(s)
Consider that common background sources
may affect only susceptible individuals
Consider the possibility that individual
complaints may have different causes that
are not necessarily related to the building
(particularly if the symptoms differ among
the individuals)
Symptoms relieved on
leaving the school, either
mmedlately, overnight, or
(in some cases) after
extended periods away from
the building
Consider that the problems may be
building-associated, though not
necessarily due to air quality. Other
stressors (e.g., lighting, noise) may
be involved.
The tables to the left and right can be helpful in defining the
complaint area, and in determining patterns in the timing of
symptoms. The complaint area may need to be revised as
the investigation continues. Keep in mind that symptoms
may result from a combination of minor problems. Using
this Wheel will not necessarily identify or solve all problems
caused by indoor air pollution.
Symptoms never relieved, • Consider that the problem may not
even after extended absence be building-related.
