 Roy Timmons is the building engineer at a small, six-story office building in the downtown area, constructed in the late 1960s before the term indoor air quality had come into existence. The building was renovated about seven years ago, so the HVAC system is reasonably up to date and functions well. And Roy has learned about the importance of IAQ. Recently some tenants have been complaining about getting itchy eyes and sore throats at work as well as frequent headaches. Some have also mentioned noticing unpleasant odors. Roy stays informed about the building and its occupants, but he can’t think of any explanation. 1. Should Roy assume that the tenants’ problems must be caused by the indoor air quality in their workplace? 2. Should Roy get some outside assistance in solving this problem?
