Heating and cooling degree days can be used to evaluate the effect of weather on energy use. For each degree the average outdoor temperature varies from a standard of 65 degrees Fahrenheit, a degree day is recorded.
Hot days are measured in Cooling Degree Days (CDD) because it would require the use of energy for cooling.
Cold days are measured in Heating Degree Days (HDD) because it would require the use of energy for heating.
Weather data is obtained from: The National Oceanic and Atmospheric Administration, or NOAA.
