• Description:
  In response to a request from a representative of management, an investigation was begun of indoor air quality conditions at the Hennepin County Health Services Building (SIC-9431), Minneapolis, Minnesota. Employees had reported upper respiratory irritation, headaches and dry eyes, particularly on floors 9 and 10 of the 12-floor building. The heating, ventilating, and air conditioning (HVAC) systems were examined, and an environmental survey was conducted on five floors. Environmental sampling revealed that particulate level, temperature, relative humidity, and carbon- dioxide (124389) concentration were similar to those commonly found indoors. The HVAC systems reduced particulate counts by about 50%. Temperature and humidity were within standard comfort guidelines. Carbon-dioxide levels were below 1000 parts per million. A deficiency was noted in that several heating, ventilating, and air conditioning systems were not cleaned properly. The authors conclude that no clear environmental cause for the reported symptoms was found. The authors recommend that the slope of the condensate collection pans in the HVAC systems be increased.
