IAQ

Definition

Indoor Air Quality (IAQ) refers to the condition of the air within and around buildings and structures, particularly as it relates to the health and comfort of building occupants.

Purpose

Maintaining good IAQ is essential for ensuring a healthy indoor environment, reducing the risk of respiratory problems, and enhancing overall comfort and productivity of occupants.

Examples of Use

• Implementing ventilation systems to improve air circulation in office buildings.
• Using air purifiers in homes to reduce allergens and pollutants.
• Conducting regular IAQ assessments in schools to ensure a healthy environment for students and staff.

Related Terms

• HVAC: Heating, Ventilation, and Air Conditioning systems that regulate indoor temperature and air quality.
• VOC: Volatile Organic Compounds, which are significant indoor air pollutants.
• Air Exchange Rate: The rate at which outdoor air replaces indoor air in a given space.

Notes

IAQ is influenced by factors such as building materials, outdoor air quality, ventilation systems, and the presence of pollutants like mold, dust, and chemicals.
