Adaptive Comfort Parameters
- [source code]
Create a set of parameters that define the acceptable conditions of the Adaptive thermal comfort model.
These parameters can be plugged into any of the components that compute Adaptive thermal comfort.

Inputs

  • ashrae_or_en15251
    A boolean to note whether to use the ASHRAE-55 neutral temperature function (True) or the EN-15251 function (False). Note that this input will also determine default values for many of the other properties of this object.
  • neutral_offset
    The number of degrees Celcius from the neutral temperature where the input operative temperature is considered acceptable. The default is 2.5C when the neutral temperature function is ASHRAE-55 and 3C when the neutral temperature function is EN-15251. You may want to use the set_neutral_offset_from_ppd() or the set_neutral_offset_from_comfort_class() methods on this object to set this value using ppd from the ASHRAE-55 standard or comfort classes from the EN-15251 standard respectively.
  • avgm_or_runmean
    A boolean to note whether the prevailing outdoor temperature is computed from the average monthly temperature (True) or a weighted running mean of the last week (False). The default is True when the neutral temperature function is ASHRAE-55 and False when the neutral temperature function is EN-15251.
  • discr_or_cont_vel
    A boolean to note whether discrete categories should be used to assess the effect of elevated air speed (True) or whether a continuous function should be used (False). The default is True when the neutral temperature function is ASHRAE-55 and False when the neutral temperature function is EN-15251.
  • cold_prevail_limit
    A number indicating the prevailing outdoor temperature below which acceptable indoor operative temperatures flatline. The default is 10C when the neutral temperature function is ASHRAE-55 and 15C when the neutral temperature function is EN-15251. This number cannot be greater than 22C and cannot be less than 10C.
  • conditioning
    A number between 0 and 1 that represents how "conditioned" vs. "free-running" the building is. 0 = free-running (completely passive with no air conditioning) 1 = conditioned (no operable windows and fully air conditioned) The default is 0 since both the ASHRAE-55 and EN-15251 standards prohibit the use of adaptive comfort methods when a heating/cooling system is active. When set to a non-zero number, a neutral temperature function for heated/cooled operation derived from the SCATs database will be used. For more information on how adaptive comfort methods can be applied to conditioned buildings, see the neutral_temperature_conditioned function in the ladybug_comfort documentation.

Outputs

  • adapt_par
    An Adaptive comfort parameter object that can be plugged into any of the components that compute Adaptive thermal comfort.
