Instead of reporting air temperature as a comfort metric, the current approach uses operative temperature
Use of operative and standard operative temperature
models in thermal biology.
Air temperature, related humidity as well as operative temperature
and air velocity were measured in the centre of the room using the thermal comfort measurement system with data logger.
Mean thermal sensation votes on operative temperature
are supposed to be reevaluated for thermal comfort of hospital personnel in hot and humid climates.
To evaluate the efficiency of thermoregulation, we used body temperature of 242 individuals taken in the wild, preferred body temperature of these individuals measured on a thermal gradient (16-45[degrees]C) in the laboratory, and operative temperature
obtained by using hollow copper tubes that were sealed at each end, painted the same color as X.
From a practical point of view, the personal-dependent model is used to adjust the environmental model which starts with the evaluation of the air velocity to determine the operative temperature
that ensure a predicted mean vote equal to zero.
From the point of view of control of inner thermal condition of building with the operative temperature
as a desired value, the thermal inertia parameters buildings and utilised HVAC system and its control are of equal importance.
1967),"The Effective Radian Field and Operative Temperature
Necessary for Comfort with Radiant Heating", ASHRAE Journal, PP.
Recommended design values of the indoor operative temperature
for buildings of different comfort categories (winter season) are :
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.
We integrated the biophysical construct of operative temperature
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).
