Calculate the percentage of people dissatisfied from radiant asymmetry.
The comfort functions used here come from Figure 5.2.4.1 of ASHRAE 55 2010. Note that, if the resulting input results in a PPD beyond what is included in this Figure, the maximum PPD will simply be returned.
radiant_diff [Required]
A number for the the radiant temperature difference between two sides of the same plane where an occupant is located [C]. This can also be a data collection representing the radiant temperature difference over time [C].
asymmetry_type [Required]
