In response to a request from the Safety Offices at the Alaska Department of Environmental Conservation (SIC-9511), Juneau, Alaska, an investigation was begun into indoor air quality. Complaints about air quality had begun shortly after the building was first occupied in 1991. Major complaints from the workers were centered on comfort related issues such as too hot, too stuffy, and noticeable odors being present. Health problems included headache, stuffy or runny nose, burning or itchy eyes, and several miscellaneous symptoms. The three story office building had about 50,000 square feet of office space and 200 occupants. The ventilation consists of a central system providing heated and cooled air to 78 zones. The system was shut down overnight. After occupant complaints, the system was set to operate with 100% outside air. At the time of the study, humidity and carbon-dioxide levels were all within the recommended limits. However, there have been occasions where the humidity levels were as low as 10%. The only deficiencies noted were the finding of standing water in the condensation drip pans and the fact that the ventilation system might be turned off while workers are inside the building outside normal working hours. The author concludes that no airborne contaminants were identified which would constitute a health hazard. The author recommends measures to help alleviate worker complaints.
