Indoor Air Quality Testing (IAQ)

 Southwest TAB & Commissioning provides two major types of services to solve your IAQ problems.

General IAQ


What Causes Indoor Air Problems?

Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in buildings/homes of all sizes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the building. High temperature and humidity levels can also increase concentrations of some pollutants.

Pollutant Sources

There are many sources of indoor air pollution in any building. These include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.

In today's fast paced construction industry, we have found that a faster and more efficient option to building FLUSH-OUT, to meet the requirements for LEED Credit 3.2, be made available to our customers. For this reason, SWTB now offers IAQ testing as an alternative to building FLUSH-OUT. We believe that the IAQ process not only provides a benchmark to which the air quality in a building can be referenced, but the test process in general takes considerably less time to complete. For IAQ Testing, LEED requires that the concentrations of 5 specific contaminants, that may be harmful to occupant health, are tested. Listed below are the 5 contaminants and the maximum permissible concentrations that are typically tested.
Formaldehyde - 27 ppb
Particulates (PM10) - 50 ug/m3
Total Volatile Organic Compounds (TVOC) - 500 ug/m3
4-Phenylcyclohexene (4-PCH) - 6.5 ug/m3
Carbon monoxide - 9ppm
