Cooling Degree Days (CDD) is a measure used to quantify the demand for cooling in a specific area over a given period. It is calculated by subtracting the base temperature (typically 65 degrees Fahrenheit or 18.3 degrees Celsius) from the average daily temperature, provided that the average daily temperature is above the base temperature. If the average daily temperature is below the base temperature, the cooling degree day is zero for that day. The sum of these daily cooling degree days over a period (usually a month, season, or year) gives the total cooling degree days for that period.

Cooling Degree Days are used by energy companies, meteorologists, and building designers to estimate the energy required for cooling buildings and other structures. They are also used to predict the demand for air conditioning and to plan for peak energy usage. Higher cooling degree days indicate a greater need for cooling, which can lead to increased energy consumption and higher utility bills.

The concept of cooling degree days is similar to that of heating degree days, which are used to measure the demand for heating. However, cooling degree days specifically focus on the need for cooling, making them a valuable tool for understanding and managing the cooling load in various regions.
