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)

PMV and PPD
