Component Index > Ladybug > 1 | AnalyzeWeatherData > CDH_HDH

Calculates heating and cooling degree-hours.
Degree-hours are defined as the difference between the base temperature and the average ambient outside air temperature multiplied by the number of hours that this difference condition exists.

Inputs

NameIDDescriptionType
_hourlyDryBulbTemperature_hourlyDryBulbTemperatureAnnual dry bulb temperature from the Import epw component (in degrees Celsius).Goo
_coolingBaseTemperature__coolingBaseTemperature_Base temperature for cooling (in degrees Celsius). Default is set to 23.3C but this can be much lower if the analysis is for a building with high heat gain or insulation.Goo
_heatingBaseTemperature__heatingBaseTemperature_Base temperature for heating (in degrees Celsius). Default is set to 18.3C but this can be much lower if the analysis is for a building with high heat gain or insulation.Goo
