ABSTRACT
Buildings should provide shelter and appropriate conditions for working, learning, leisure, and comfortable living. A built environment should be safe, with no health hazards for its users due to poor design and construction, and/or inadequate operation and maintenance and performance. Negligence and failing to take any actions required to comply with appropriately set quality criteria for the indoor environment can lead to serious indoor environmental problems that result in substantial financial costs and other undesirable consequences for health and comfort. It is the purpose of this chapter to describe how ventilation and indoor air quality (IAQ) in different types of buildings, homes, schools, and offices affects these aspects of human life.
