Module 4 – Recognizing and Addressing IAQ Problems

How can a building manager know if there are any indoor air quality IAQ problems? And, if there is a problem, how can you resolve it? The fourth module of the CCIAQ’s Guide for Indoor Air Quality answers these questions.

Complaints from building occupants can be a significant help in detecting, locating and diagnosing compromised IAQ. We have given guidance on how to handle IAQ complaints, including a sample complaint form and an investigative process. Also we listed typical sources of contaminants, along with factors that can affect IAQ, such as chemicals and ventilation flaws. We described effective communication with occupants, as well as the effects of IAQ on health.

The module’s second half gives advice on dealing with IAQ problems. There are instructions for an effective walk-through inspection of the building. A checklist covers items to look for, such as contaminants, faults in the building and its systems, and occupant activities. A second checklist offers ideas on causes and possible effects. For example, widespread symptoms among occupants may indicate a problem that is spread by the building’s ventilation system.

In case you need a more thorough assessment, we’ve given steps for evaluating the building’s heating, ventilation and air conditioning system. Also, we described the pathways and sources of pollutants, as well as methods for air sampling. There are recommendations on determining solution to problems, and on where and how to seek outside help, if it is necessary.
