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 weatherstationoutside 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 toheat 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 tocool buildings.

The following degree day data is based on the weather station data collected at our office on Hwy. 33 in Tarboro, NC.
