Function to calculate Predicted Mean Vote (PMV).
calcPMV(ta, tr, vel, rh, clo=.5, met=1, wme=0, basMet=58.15)PMV - Predicted Mean Vote
a numeric value presenting air temperature in [degree C]
a numeric value presenting mean radiant temperature in [degree C]
a numeric value presenting air velocity in [m/s]
a numeric value presenting relative humidity [%]
a numeric value presenting clothing insulation level in [clo]
a numeric value presenting metabolic rate in [met]
a numeric value presenting external work in [met]
a numeric value presenting basal metabolic rate [w/m2]
Code implemented in to R by Marcel Schweiker. Further contribution by Sophia Mueller and Shoaib Sarwar.
The PMV is an index that predicts the mean value of the thermal sensation of a large group of people on a sensation scale expressed from (-3) to (+3) corresponding to the categories cold, cool, slightly cool, neutral, slightly warm, warm and hot. PMV model is limited to air speeds below 0.20 m/s.
Note that the adjustments in the value for basMet need to be made with great cautiousness as the PMV calculation is an empirical model and might not be valid for other values of basMet than the one commonly used.
