A growing emphasis on energy efficiency over approximately the past 30 years has resulted in buildings that sealed much tighter to limit the infiltration of outdoor air. This, along with deferring maintenance to save money and the increasing number of consumer products that contain harmful chemicals, has led to deteriorating indoor air quality and more frequent complaints from building occupants.
