Challenges for Indoor Air Quality Management

Abstract

We live indoors. In the developed countries, people spent
80-90% of time in buildings. Therefore, among the environmental
factors, indoor air quality (IAQ) is a significant,
if not the most significant, factor affecting human health.
Scientific evidence has indicated that indoor air can be
more seriously polluted than the outdoor air in even the
largest and most industrialized cities. Indoor air pollution
causes long- and short-term health problems and, depending
on the severity, can even make staying indoors
very uncomfortable. Management of IAQ is a complicated
task due to complexity of pollution sources and a
limited number of measures applicable such as reducing
contaminants at the source, improving ventilation, and,
when relevant, purifying the indoor air
