What is another word for degree day?
Pronunciation: [dɪɡɹˈiː dˈe͡ɪ] (IPA) 
Degree day is a term used to describe the measurement of energy used to heat or cool a building. This value is calculated by subtracting the average outdoor temperature from a reference point, typically 65 degrees Fahrenheit. However, there are several synonyms that can be used interchangeably with degree day, such as heating degree day (HDD), cooling degree day (CDD), and balance point temperature. Heating degree day indicates the temperature below which a building needs to be heated, while cooling degree day is the temperature above which a building needs to be cooled. Balance point temperature refers to the outdoor temperature where no heating or cooling is needed. Regardless of the synonym used, degree days are a critical metric for managing energy usage in commercial and residential buildings.
