Heating and Cooling Statistics for Raleigh, NC
Heating and cooling degree days are a tool used to normalize energy use across different areas. Degree days are based on the assumption that at 65 degrees Fahrenheit no heating or cooling is necessary inside your home to feel comfortable.
The following example calculations were provided by the National Weather Service, weather.gov.
The high temperature for a particular day was 90°F and the low temperature was 66°F. The temperature mean for that day was: 78°F
78°F – 65°F = 13 Cooling Degree Days
The high temperature for a particular day was 33°F and the low temperature was 25°F. The temperature mean for that day was: 29°F
65°F – 29°F = 36 Heating Degree Days.
