DEGREE DAY Meaning and
Definition
-
Degree day is a meteorological concept used to quantify the amount of heating or cooling needed in a specific location over a specific period of time. It is a metric that measures the deviation of the mean daily outdoor temperature from a base temperature, typically 65 degrees Fahrenheit (18 degrees Celsius), which represents the approximate temperature at which heating or cooling systems are not required.
To calculate degree days, the average daily outdoor temperature is subtracted from the base temperature. If the result is positive, it represents heating degree days (HDD), indicating the number of degrees of heating required to maintain a comfortable indoor temperature. Conversely, if the result is negative, it signifies cooling degree days (CDD), indicating the number of degrees of cooling required.
Degree days are widely used in the fields of energy management, building design, and climatology to estimate energy demands and assess environmental heating or cooling requirements. Utility companies often employ degree days to project energy consumption, determine billing rates, and plan resource allocation. Additionally, degree days are crucial for conducting energy audits, evaluating building insulation, and designing efficient heating, ventilation, and air conditioning (HVAC) systems.
In summary, degree days provide a quantifiable measurement of heating or cooling requirements in a given location by comparing average outdoor temperatures to a base temperature. They are valuable tools for energy planning, resource management, and assessing energy efficiency in buildings.

Etymology of DEGREE DAY
The word "degree day" does not have a specific etymology of its own. Instead, it is a compound term composed of two separate words – "degree" and "day", each with their own etymologies:
1. Degree: The word "degree" originated from the Latin word "gradus", meaning "step" or "grade". It entered Middle English via Old French and was used to denote a measurement or unit of progress. Over time, its usage expanded to include the measurement of temperature.
2. Day: The word "day" originated from the Old English word "dæg", which can be traced back to the Proto-Germanic root "*dagaz". Its meaning refers to the period of prolonged light between sunrise and sunset.
