DEGREE DAY

A degree day is a measure of heating or cooling. Totalised degree days from an appropriate starting date are used to plan the planting of crops and management of pests. Weekly or monthly degree-day figures may also be used within an energy monitoring and targeting scheme to monitor the heating and cooling costs of climate controlled buildings, while annual figures can be used for estimating future costs.
