If your building does not hire a firm to perform annual IAQ audits, determine if you have the resources—mostly staff time—to complete the IAQ audit in-house. The IAQ manager needs one hour per 20,000 ft2 to conduct the baseline audit and less than half that time to complete a follow-up (it will take several additional hours to review the education modules and complete the IAQ audit report). The key is to have someone on staff that has the time to go through the building identifying auditory, visual and olfactory problems. The designated IAQ manager should understand building systems and be familiar with building operations. The credit does not require any testing, balancing or technically involved preventive maintenance.
