The climate control system should maintain control room ambient temperatures of 20–24°Celsius (C)) (68–75 degrees Fahrenheit (F) in winter and 23–26 degrees C (73–79 degrees F) in summer.
Additional Information: The above temperature ranges are based upon calculations of the human comfort zones. In the summer thermal comfort zone, workers wearing light clothing will be comfortable; in the winter thermal comfort zone, workers wearing heavy indoor clothing (e.g., sweaters) will be comfortable. These comfort zones assume sedentary work; personnel performing “light work” (e.g., actively monitoring spatially distributed equipment or retrieving procedures or manuals) will be comfortable at higher and lower temperatures, respectively. Air movement rates of less than 0.25 m/second
(50 ft/minute) are also assumed. More information on comfort zones may be found in ISO 7730 (2005) and ANSI/ASHRAE 55 (2013).0700, 5680
