Most of the time we think about indoor air quality (IAQ) problems in terms of buildings that are already completed and occupied. Those problems may consist of mold growth and/or improper ventilation. But have you ever thought about the kinds of IAQ problems that can occur in buildings that may be occupied but are still under construction?
The Sheet Metal and Air Con-ditioning Contractors’ National Association (SMACNA) says there are real problems that can happen, and the organization would like contractors to take the necessary precautions when working in an occupied building.
