• Description:
  In response to a request from a group of employees at the Indiana Bell Telephone Company (SIC-4813), an investigation was made into indoor environmental quality at the South Division Office, Bloomington, Indiana. Several employees had reported symptoms including eye irritation, nasal irritation, nasal congestion, fatigue, skin irritation, headaches, and dizziness. The office occupied a one-story building of over 29,500 square feet, employing 200 workers on three 8 hour shifts per day, 7 days a week. Carbon- dioxide (124389) concentrations ranged from 425 to 825 parts per million (ppm). Indoor air temperature measurements ranged from 70 to 74 degrees-F. Relative humidity ranged from 68% to 88%. Deficiencies were found in the heating and air conditioning systems which included inadequate cooling capacity, insufficient supply air flow rates, ductwork leakage, and inadequate fan sizing. The authors conclude that no specific building problem that would clearly account for the reported symptoms was found. The authors recommend that specific deficiencies in the ventilation system be corrected.
