On a cooling day, the average temperature of the day is 18.3°C or higher. Cooling degree days allow conclusions to be drawn about the weather-related energy demand for the cooling of buildings.
They correspond to the sum of the daily difference between a target indoor air temperature of 18.3°C and the average daily temperature of all cooling days.
The number of cooling days and cooling degree days has increased significantly in recent decades due to climate change. This trend will continue in the future.
