Description

Function to calculate ankle draft using the predicted percentage of dissatisfied.

Usage

calcAD(ta, tr, vel, rh, clo, met, vAnkle)

Value

Predicted Percentage of Dissatisfied occupants with ankle draft in [%]

Acceptability in [boolean]

Arguments

ta

a numeric value presenting air temperature in [degree C]

tr

a numeric value presenting mean radiant temperature in [degree C]

vel

a numeric value presenting air velocity in [m/s]

rh

a numeric value presenting relative humidity [%]

clo

a numeric value presenting clothing insulation level in [clo]

met

a numeric value presenting metabolic rate in [met]

vAnkle

air speed at the 0.1 m (4 in.) above the floor [m/s]

Author

Code implemented in to R by Shoaib Sarwar. Further contribution by Marcel Schweiker.

Details

Calculates the percentage of thermally dissatisfied people with the ankle draft (0.1 m) above floor level.This equation is only applicable for velocity < 0.2 m/s (40 fps)
