An Indoor Air Quality (IAQ) Assessment is a process of evaluating the air quality within a building or a specific indoor environment. The purpose of an IAQ assessment is to identify potential indoor air quality problems and help improve the health and comfort of the occupants.

An IAQ assessment typically involves the following steps:

• Site Inspection: Conducting a visual inspection of the building, including ventilation systems, air handlers, and potential sources of indoor air pollutants.
• Measurement of Indoor Air Quality Parameters: Measuring parameters such as temperature, humidity, carbon dioxide, carbon monoxide, particulate matter, and volatile organic compounds (VOCs).
• Identification of Sources of Pollution: Identifying potential sources of indoor air pollution, such as building materials, furnishings, cleaning products, and smoking.
• Data Analysis: Analyzing the data collected to identify potential sources of indoor air pollution and evaluate the overall indoor air quality.
• Mitigation: Developing strategies to mitigate the identified indoor air quality problems, such as improving ventilation, reducing indoor pollutants, or introducing air filtration systems.
• Reporting: Preparing a report summarizing the findings of the assessment, including the potential indoor air quality problems and recommended mitigation strategies.

An IAQ assessment is typically conducted in response to specific concerns about indoor air quality, such as occupant complaints or a history of health problems related to indoor air quality. An IAQ assessment can help building owners and managers identify potential indoor air quality problems and develop strategies to improve the health and comfort of the occupants.
