Operative temperature

In determining thermal comfort, operative temperature is roughly the average of the air and mean radiant temperature (MRT) a person is experiencing.

For calculation of occupants' overall thermal balance, environmental parameters include operative temperature (weighted sum of air and mean radiant temperatures), mean air velocity, and relative humidity.
Regarding the first aspect, for the same air temperature, the thermal comfort conditions guaranteed by a radiant system are better than those of a convective system, since the operative temperature is higher (or lower in summer conditions) than the one of an enclosure equipped with a convective system (Olesen 2002b).
