What Are Heating and Cooling Degree Days

    https://www.weather.gov/key/climate_heat_cool
    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.
