Indoor Air Quality - Home

John Huang, Ph.D., PE and John Poullain, PE

This three-hour online course provides general guidelines and measures to take for the improvement of indoor air quality in the home. The topics cover the causes of indoor air quality problems, sources and types of air pollutants, ventilation, air exchanges and outdoor air entry. This course covers how to improve the air quality and how to identify and measure pollutants. Source-specific pollutants including radon, tobacco smoke, stoves, fireplaces, pesticides, asbestos, related health effects and ways to reduce exposure are discussed. Office air quality and considerations for new home constructions are briefly discussed. The course covers many links and references to informative sources covered in the text topics.

There are many regulations for air quality but most pertain to outdoor air quality and the emission of pollutants into the atmosphere. Until now indoor air quality standards could not be easily developed because monitoring devices were not available for accurate measurements. Indoor air quality is a complex problem which is hard to target because of ever changing types and levels of pollution and a key factor is the occupant’s susceptibility and perception of indoor conditions. Factors affecting IAQ are pollutant sources, operation and maintenance of ventilation systems, moisture and humidity. IAQ is basically controlled by the following measures:

1. Manage the sources of pollutants by removal or protect the occupants with physical barriers.
2. Ventilate the building with proper rates of air exchange.
3. Clean the air and remove pollutants with filtration.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
