Degree days are essentially a simplified representation of outside air-temperature data.
Degree day data is widely used within the energy industry for calculations relating to the outside air temperature on building energy consumption.
Heat Degree Days (HDD)
Heating degree days, or “HDD”, are a measure of how much (in degrees), and for how long (in days), outside air temperature was lower than 65 degrees. They are used for calculations relating to the energy consumption required to heat buildings.
Cooling Degree Days (CDD)
Cooling degree days, or “CDD”, are a measure of how much (in degrees), and for how long (in days), outside air temperature was higher than 65 degrees. They are used for calculations relating to the energy consumption required to cool buildings.
