In response to a request from the State of Colorado, Office of the State Public Defender (SIC-9222), an investigation was made of indoor air quality at the office in the Petroleum Building, Denver, Colorado. The building was built in 1957 and consisted of 14 stories plus a penthouse in downtown Denver. Ventilation in the building consisted of a central heating, ventilation and air conditioning (HVAC) system which supplied air to the perimeter offices on the lower 14 floors, a separate HVAC system for the penthouse, the core system which had air handling units located on each floor, and fan coil units located in the outside offices. Windows in the building could also be opened. Renovations had been underway in the building and workers complained about itchy eyes and stuffy/runny nose. Temperature and humidity measurements were consistent throughout the building, ranging from 74 to 77 degrees-F and 20 to 22% relative humidity. Carbon-monoxide (630080) levels were less than 1 part per million. The author concludes that no airborne contaminant was identified which would constitute a health hazard. The core ventilation system needed to be balanced, and the fan coil units required extensive cleaning. The author recommends specific measures to improve the indoor air quality and to reduce the noise levels near some of the air diffusers.
