Healthy Air
Building-Related Illness
A diagnosable illness with identifiable symptoms whose cause can be
directly attributed to airborne pollutants within a building such as
Legionnaires disease or hypersensitivity pnuemonitis.
The American Society of Heating,
Refrigeration, and Air Conditioning Engineers
(ASHRAE) are engineers in the HVAC
industry who establish standards for the
mechanical equipment used to heat, cool and
ventilate buildings. Many local, state, national
and international buildings codes are based
on these standards. ASHRAE Standard
62.1,Ventilation for Acceptable Indoor Air
Quality, is the ventilation standard for
commercial buildings. It states “indoor air
quality is acceptable when there are no known
contaminants at concentrations determined to
be harmful to building occupants, as
determined by cognizant authorities, and
when a substantial majority (80% or more) of
those persons exposed to the indoor air do not
express dissatisfaction with its quality.” This
standard sets minimum outdoor air ventilation
rates and requires other measures intended to
provide indoor air quality that is both
acceptable to human occupants and
minimizes negative effects on health.
