Air Conditioning Heating and Ventilation <br /> <br /> ASHRAE 55 <br /> <br />Ambient comfort levels <br /> <br />Air conditioning systems that are properly installed, calibrated and maintained, <br />should generally provide adequate comfort. Comfort, however is subjective and <br />depends on a number of factors, including but not limited to personal physical <br />conditions, system operation, outside weather temperature, humidity, and ioar <br />quality. <br /> <br />ASHRAE 55 indicates a normal temperature range for comfort between 68 and <br />75 degress f. Generally, a building temperature is at approximately 70-72 F; <br />this range is considered the nuetral range. With this range the follow scale has <br />been developed to gage the comfort level in the working environment. <br /> <br /> +3 Hot <br /> +2 Warm <br />+1 Slightly Warm <br /> <br />0 Neutral <br /> <br />-1 Slightly Cool <br />-2 Cool <br />-3 Cold <br /> <br />When assessing an area where discomfort is an issue; after an initial review of <br />that the room temperature is set according to the requirements established by <br />the ASHRAE guidelines, verification with the occupants is suggested to <br />determine the level of deviation from the neutral zone. <br /> <br />MG June/7/2002 <br /> <br /> <br />
