• Description:
  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 evaluation included questionnaires given to building employees
  
  an examination of the heating, ventilation and air conditioning systems (HVAC) operative at the site
  
  a study of the identifiable sources of contamination
  
  interviews with the representatives of the building management and building employees
  
  and a survey to consider the relative comfort zones in operation in the building. 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 1ppm. 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 deficiencies in the ventilation system. The author recommends measures to improve the ventilation system.
