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