Beräkna PMV och PPD

On this page you can calculate the Predicted mean Vote (PMV), and Predicted Percentage Dissatisfied (PPD).

For interpretation of the results, read the standard, ISO 7730.

Calculation of PMV and PPD

M (W/m2), Metabolic energy production (58 to 232 W/m2)
W (W/m2), Rate of mechanical work, (normally 0)
Ta (C), Ambient air temperature (10-30)
Tr (C), Mean radiant temperature (often close to ambient air temperature)
v (m/s), Relative air velocity (0.1 to 1 m/s)
rh (%), Relative humidity
Icl (clo), basic clothing insulation (1 clo = 0.155 W/m2K)

Results for PMV and PPD

PMV -3 cold to +3 hot

PPD (%)


PMV 2008 ver 1.0, Ingvar Holmer.
