We are not AIR. Conventional HVAC system designs uses air temperature as the only indicator of thermal comfort states - so long as the temperatures sits within a range, it is safe to assume that person is comfortable - at least that’s what the current standards are telling us.
We are individual humans that are different. Needless to say, the differences between the occupants are somewhat striking: between men and women, and between occupants of different build, age and weight, the heat-producing mechanism alone would result in a wide range of metabolic rates, let alone the differences caused by different muscle/fat ratios, etc.
