Why are the comfort parameters within PMVMap, UTCIMap and AdaptiveMap different?

Hi, just curious about the difference in the map comforts.

I wanted to run a study on Adaptive Parameters, but found that the input for the comfort parameters is based off indoor/outdoor temp diff, etc. Meanwhile, UTCI is based on the individual’s tolerance level of hot and cold, and PMV is based off humidity.

Is there a way I can unify it or understand this better so I can run a proper thermal comfort study for both a base building with no mechanical ventilation/air conditioning vs the same building with ACMV?

TIA!
