A plan has been developed for assessing the air quality of non-industrial buildings. It consists of ten tasks. Tasks 1 and 2 are designed to obtain the background information on the building itself, its surroundings and occupants. Task 3 provides an opportunity for the project team to review theresults and to determine if an in-depth study is necessary. Tasks 4, 5 and 6assess the performance of the building's HVAC systems and identify the contaminants present.
This overview explains why indoor air quality (lAQ) has recently attracted so much attention what are the major sources of indoor air pollution, and what are the health effects of concern. It discusses differences among occupational, outdoor, and indoor air pollution problems including some of the different measurement needs. It also covers the total exposure concept, and discusses the California IAQ Program. Emerging trends in indoor air quality measurement techniques are presented in the final part of the paper.
