Indoor Air Quality Consulting

Indoor Air Quality

The term Indoor Air Quality describes the quality of air within a building and is of interest due to its impact on the health of the building occupants. Indoor concentrations of some air pollutants are sometimes two to five times higher than outdoor concentrations. Although the importance of poor indoor air quality (IAQ) in occupational settings has long been realized, awareness of IAQ in residential, commercial and public buildings is a more recent development. The mounting concern over IAQ has paralleled the increase in reported illnesses related to indoor air pollutants.

A number of historical events have contributed to the increase in indoor air quality problems, including:

  • The development and use of synthetic building materials and furnishings
  • The tightening of buildings in the 1970s for energy conservation
  • Introduction of chemical-intensive devices, such as computers, photocopiers and laser printers, into the workplace
  • Changes in demographics that resulted in the majority of workers spending 75 to 90 percent of their time indoors

The US Environmental Protection Agency (EPA) ranks indoor air pollution as one of the top five environmental risks to public health.
