Cooling/heating degree hours (CDH/HDH) represent the required energy to cool/warm the indoor environment to reach the comfort zone. The higher the degree hours, the higher the cooling/heating demand is, and the greater the energy required to maintain indoor thermal comfort conditions [48]. For annual applications, most of the locations have both CDH and …

78°F - 65°F = 13 Cooling Degree Days. Example 2: The high temperature for a particular day was 33°F and the low temperature was 25°F. The temperature mean for that day was: ( 33°F + 25°F ) / 2 = 29°F. Because the result is below 65°F: 65°F - 29°F = 36 Heating Degree Days. The calculations shown in the two examples above are performed ...
