In response to a request from the Facilities Manager of Mesa County Support Services Department concerning the Mesa County Courthouse and Annex (SIC-9222), Grand Junction, Colorado, an evaluation was undertaken of indoor air quality as employees had been suffering with itchy watery eyes, chronic sinus problems, headaches, and other symptoms. Over the past 5 years each of the four courtrooms in the Annex had its own ventilation (heating and air conditioning) system installed. The areas of the Annex building which had a central HVAC system were the source of most complaints. No carbon-dioxide (124389) levels were recorded above 1000 parts per million (ppm) in any section of the building. Temperatures inside ranged from 72 to 79 degrees-F and relative humidity was 17 to 20%. Carbon-monoxide (630080) levels were less than 1 ppm. There were times when the amount of outside air mixed in were inadequate. The author concludes that no airborne contaminant which would constitute a health hazard was identified; however, there were defciencies in the ventilation system. The author recommends measures to improve the ventilation system.
