This book is a comprehensive examination of the phenomenon of poor indoor air quality (IAQ) characterized as sick or problem buildings. Significant emphasis is given to defining the nature of the problem, the various potential causal and risk factors, problem building diagnostic protocols and contaminant measurements, and the mitigation of IAQ problems, including case histories. The book features a discussion on the potential causal factors studied extensively in Europe and recognized in North America as well.Chapter 1.
