calcVTG: PPD with Vertical Air Temperature Gradient
Description
Function to calculate vertical air temperature gradient using the predicted percentage of dissatisfied.
Usage
calcVTG(ta, tr, vel, rh, clo, met, v_tmp_grad)
Value
Predicted Percentage of Dissatisfied with vertical temperature gradient 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]
v_tmp_grad
vertical temperature gradient between the feet and the head [degree C/m]
Author
Code implemented in to R by Shoaib Sarwar. Further contribution by Marcel Schweiker.
Details
Calculates the percentage of thermally dissatisfied persons with a vertical temperature gradient between feet and head. Applicable only for velocity(vel) < 0.2 m/s
