Occupant Comfort |
OCCUPANT COMFORT ZONE(S) Comfort Zones. Because of high energy costs, the DPW&T Building Services Division has established temperature Comfort Zones for heating and cooling. In ![]() ![]() Relative Humidity. The relative humidity at surfaces is typically higher than it is at the center of a room. When the relative humidity at surfaces is above 70%, mold growth can occur. To control microorganisms, it is best to keep relative humidity below 60% to control mold and 50% to control dust mites. The accuracy of the standard humidity range is 3/5th% to 3% (say 2%) over the established comfort zone. For libraries and archival materials, a stable temperature of no higher than 70 degrees and a relative humidity of between 30% and 60% is recommended. LIGHTING STANDARDS Because of increasing energy costs, Building Services has adopted the following lighting (illumination) standards after review of the recommendations provided by the Illuminating Engineering Society of North America. In 2005, a heavy duty light meter was purchased to assist building services personnel in periodically checking minimum lighting levels known as foot-candles (fc). |
