Annual Heating Degree Days (HDD): A form of Degree Day used to estimate energy requirements for heating. Typically, heating degree days are calculated as how much colder the mean temperature at a location is than 65°F on a given day. For example, if a location experiences a mean temperature of 55°F on a certain day, there were 10 HDD that day because 65 - 55 = 10, according to the National Weather Service.

Annual Cooling Degree Days (CDD): A form of Degree Day used to estimate energy requirements for air conditioning or refrigeration. Typically, cooling degree days are calculated as how much warmer the mean temperature at a location is than 65°F on a given day. For example, if a location experiences a mean temperature of 75°F on a certain day, there were 10 CDD that day because 75 - 65 = 10, according to the National Weather Service.
