Cooling Degree-Days
Description:  Population-weighted, annual cooling degree-day normals for 1971-2000. A cooling degree-day is a measure of how hot a location is over a period of time relative to a base temperature, most commonly specified as 65 degrees Fahrenheit. The measure is computed for each day by subtracting the base temperature (65 degrees) from the average of the day's high and low temperatures, with negative values set equal to zero. Each day's cooling degree-days are summed to create a cooling degree-day measure for a specified reference period. Cooling degree-days are used in energy analysis as an indicator of air-conditioning energy requirements or use.

Heating Degree-Days
Description:  Population-weighted, annual heating degree-day normals for 1971-2000. A heating degree-day is a unit of measure of how cold a location is over a period of time relative to a base temperature, most commonly specified as 65 degrees Fahrenheit. The measure is computed for each day by subtracting the average of the day's high and low temperatures from the base temperature (65 degrees), with negative values set equal to zero. Each day's heating degree-days are summed to create a heating degree-day measure for a specified reference period. Heating degree-days are used in energy analysis as an indicator of space-heating energy requirements or use.
