Degree Day Data
Degree days are essentially a simplified representation of outside
air-temperature data. They are widely used in the energy industry for
calculations relating to the effect of 
outside air temperature on building
energy consumption.
"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", 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.
The following degree day data is based on the weather station data collected at our office on Hwy. 33 in Tarboro, NC.
