Indoor Air Quality (IAQ) Basics for Schools
Understanding IAQ Problems and Solutions
Over the past forty or fifty years, exposure to indoor air pollutants
has increased due to a variety of factors, including the construction
of more tightly sealed buildings, reduced ventilation rates to save
energy, the use of synthetic building materials and furnishings, and
the use of chemically-formulated personal care products, pesticides,
and housekeeping supplies. In addition, our activities and decisions,
such as delaying maintenance to "save" money, can lead to
problems from sources and ventilation. Four basic factors affect IAQ:
sources of indoor air pollutants, pollutant pathways, occupants, and
the heating, ventilation, and air-conditioning (HVAC) system.
