For example, with clothing level = 1, metabolic rate = 1.1, and air speed 0.1 m/s, a change in air temperature and mean radiant temperature from 20 °C to 24 °C would lower the maximum acceptable relative humidity from 100% to 65% to maintain thermal comfort conditions.
The recommended level of indoor humidity is in the range of 30–60% in air conditioned buildings, [34] [35] but new standards such as the adaptive model allow lower and higher humidity, depending on the other factors involved in thermal comfort. Recently, the effects of low relative humidity and high air velocity were tested on humans after ...
This method, also known as the adaptive comfort model, is applicable in buildings without mechanical cooling (and no operating heating system) where occupants' met rates are 1.0-1.3 met and their clothing levels are 0.5-1.0 clo. For this model the standard provides a graph of acceptable indoor temperature limits at prevailing mean outdoor ...
