CDH_HDH - [source code]
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
hourlyDryBulbTemperature [Required]
Annual dry bulb temperature from the Import epw component (in degrees Celsius).coolingBaseTemperature [Default]
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.heatingBaseTemperature [Default]
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.

A ummary of the input.hourly_coolingDegHours
Cooling degree-hours for each hour of the year. For visualizations over the whole year, connect this to the grasshopper chart/graph component.hourly_heatingDegHours
Heating degree-days for each hour of the year. For visualizations over the whole year, connect this to the grasshopper chart/graph component.daily_coolingDegHours
Cooling degree-days summed for each day of the year. For visualizations of over the whole year, connect this to the grasshopper chart/graph component.daily_heatingDegHours
Heating degree-days summed for each day of the year. For visualizations of over the whole year, connect this to the grasshopper chart/graph component.monthly_coolingDegHours
Cooling degree-days summed for each month of the year.monthly_heatingDegHours
Heating degree-days summed for each month of the year.annual_coolingDegHours
The total cooling degree-days for the entire year.annual_heatingDegHours
The total heating degree-days for the entire year.
