- [source code]
Calculate heating and cooling degree-days from outdoor dry bulb temperature.

Inputs

  • dry_bulb [Required]
A data collection representing outdoor dry bulb temperature [C]
  • heat_base
A number for the base temperature below which a given hour is considered to be in heating mode. Default is 18 Celcius, which is a common balance point for buildings.
  • cool_base
A number for the base temperature above which a given hour is considered to be in cooling mode. Default is 23 Celcius, which is a common balance point for buildings.

Outputs

  • hourly_heat
A data collection of heating degree-days. Plug this into the 'Time Interval Operation' component to get the number of degree-days at different time intervals.
  • hourly_cool
A data collection of cooling degree-days. Plug this into the 'Time Interval Operation' component to get the number of degree-days at different time intervals.
  • heat_deg_days
A value indicating the total number of heating degree-days over the entire input _dry_bulb collection.
  • cool_deg_days
A value indicating the total number of cooling degree-days over the entire input _dry_bulb collection.
