Adaptive Comfort Parameters
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_en
A boolean to note whether to use the ASHRAE-55 neutral temperature function (True) or the european neutral function (False), which is consistent with both EN-15251 and EN-16798. 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 (consistent with 90% PPD) and 3C when the neutral temperature function is EN (consistent with comfort class II). For ASHRAE-55, the following neutral offsets apply.
For the EN standard, the following neutral offsets apply.
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.
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). Note that continuous air speeds were only used in the older EN-15251 standard and are not a part of the more recent EN-16798 standard. When unassigned, this will be True for discrete air speeds.
cold_prevail_limit
A number indicating the prevailing outdoor temperature below which acceptable indoor operative temperatures flat line. The default is 10C, which is consistent with both ASHRAE-55 and EN-16798. However, 15C was used for the older EN-15251 standard. 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 the EN 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.
