NOTA: In questo diagramma psicrometrico, l'ascissa rappresenta la temperatura dell'aria secca, mentre la temperatura media radiante (MRT) è fissa e controllata tramite la casella di input. Ogni punto nel diagramma ha la stessa MRT, che definisce il limite della zona di comfort. In questo modo, è possibile osservare come le variazioni della MRT influenzano il comfort termico. È inoltre possibile continuare a utilizzare il pulsante della temperatura operativa, ma ogni punto avrà comunque la stessa MRT.

Limits of Applicability: This standard is only applicable to healthy individuals. This standard does not apply to occupants: a) whose clothing insulation exceed 1.5 clo; b) whose clothing is highly impermeable; or c) who are sleeping, reclining in contact with bedding, or able to adjust blankets or bedding.

The CBE comfort tools automatically calculates the relative air speed and the dynamic clothing insulation .

NOTE: In this psychrometric chart the abscissa is the operative temperature and for each point dry-bulb temperature equals mean radiant temperature (DBT = MRT). The comfort zone represents the combination of conditions with the same DBT and MRT for which the PMV is between -0.5 and +0.5, according to the standard.

NOTE: This chart represents only two variables, dry-bulb temperature and relative humidity. The PMV calculations are still based on all the psychrometric variables, but the visualization becomes easier to understand.

NOTE: This chart represents only two variables, air speed against operative temperature. The operative temperature for each point is determined by dry-bulb temperature equals mean radiant temperature (DBT = MRT). The calculation of PMV comfort zone is based on all the psychrometric variables, with PMV values between -0.5 and +0.5 according to the standard.

Limits of Applicability: The elevated air speed comfort zone method is to all spaces where the occupants have activity levels between 1.0 and 2.0 met and clothing insulation between 0.0 and 1.5 clo. There is no upper limit to air speed if occupant's total clothing > 0.7 clo and metabolic rate > 1.3 met.
