What is "indoor air quality"?
Indoor air quality (also called "indoor environmental quality") describes how inside air can affect a person's health, comfort, and ability to work. It can include temperature, humidity, lack of outside air (poor ventilation), mold from water damage, or exposure to other chemicals. Currently, OSHA has no indoor air quality (IAQ) standards but it does provide guidelines about the most common IAQ workplace complaints.
What is considered good IAQ?
The qualities of good IAQ should include comfortable temperature and humidity, adequate supply of fresh outdoor air, and control of pollutants from inside and outside of the building.
What are the most common causes of IAQ problems?
The most common causes of IAQ problems in buildings are:
- Not enough ventilation, lack of fresh outdoor air or contaminated air being brought into the building
- Poor upkeep of ventilation, heating and air-conditioning systems, and
- Dampness and moisture damage due to leaks, flooding or high humidity
- Occupant activities, such as construction or remodeling
- Indoor and outdoor contaminated air
