US heating demand typically surpasses cooling demand after autumnal equinox
Data from the U.S. Energy Information Administration suggests that heating a home is more costly for consumers than cooling the same property during the warm season. A heating degree day (HDD) is calculated by determining how many degrees the temperature drops below 65 °F. For example, a day with an average temperature of 50 °F is considered to have 15 HDDs. A cooling degree day (CDD) measures how much the average temperature is above 65 °F. For instance, a day with an average temperature of 77 °F is considered to have 12 CDDs.
