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
| Name | ID | Description | Type |
|---|---|---|---|
| Hourly Dry Bulb Temperature | _hourlyDryBulbTemperature | Annual dry bulb temperature from the Import epw component (in degrees Celsius). | Goo |
| Cooling Base Temperature | _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 |
| Heating Base Temperature | _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 |
Outputs
| Name | ID | Description | Type |
|---|---|---|---|
| Out | readMe! | A ummary of the input. | String |
| Hourly cooling Deg Hours | 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. | Goo |
| Hourly heating Deg Hours | 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. | Goo |
| Daily cooling Deg Hours | 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. | Goo |
| Daily heating Deg Hours | 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. | Goo |
| Monthly cooling Deg Hours | monthly_coolingDegHours | Cooling degree-days summed for each month of the year. | Goo |
| Monthly heating Deg Hours | monthly_heatingDegHours | Heating degree-days summed for each month of the year. | Goo |
