[vlbwcuby] humidity temperature tradeoff

given a limited energy budget to heat or seem to heat an insulated room, should the energy be spent on increasing humidity (making the room feel warmer to humans) or directly increasing temperature?  running a humidifier -- inducing a phase change from liquid water to gas -- requires energy.

it seems increasing humidity by passive evaporation could be done with very cheaply (just need large surface area), though inducing a phase change in water consumes ambient energy, decreasing temperature.

perceived temperature at high humidity probably depends critically on how much activity the human is doing, how much the human is sweating.  at low humidity, there could be a large range of activity levels that the human could be doing and remain comfortable (homeostasis through sweating); at high, the range is very narrow.

the assumption that the room is perfectly insulated is probably unrealistic.
