Thermal Comfort Indices using a List of Climatic Conditions

Description

calcComfInd calculates one or more thermal comfort indices using a list of climatic conditions.

Usage

calcComfInd(lsCond, request = "all")

comfind(lsCond, request = "all")

Arguments

lsCond

a list of climatic conditions and additional variables necessary for one or more of the indices (see details below).

request

a vector with one or more comfort indices (see details below).

Details

The list lsCond could contain one or more of the following variables:

ta Air temperature in (degree C)
tr mean radiant temperature in (degree C)
vel Air velocity in (m/s)
rh Relative Humidity (%)
clo clothing (clo)
met metabolic rate (met)
wme External work (met)
tu turbulence intensity (%)
tmmo mean monthly outdoor temperature in (degree C)
ltime Exposure time (min)
pb Barometric pressure (torr)
wt weight (kg)
ht height (cm)
trm Running mean outdoor temperature in (degree C)
age age (years)
gender gender (female = 1)
tsk mean skin temperature in (degree C)
psych factor related to fixed effect on perceived control
apCoeff adaptive coefficient for pmv
epCoeff expectancy factor for pmv
asCoeff adaptive coefficient for set
esCoeff expectancy factor for set
asv actual sensation vote (0 = neutral)
tao outdoor air temperature
rho outdoor relative humidity
frad 0.7(for seating), 0.73(for standing) [-]
eps emissivity [-]
ic 1.084 (average permeability), 0.4 (low permeability)
tcr initial values for core temp
tsk initial values for skin temperature
basMet basal metabolic rate
warmUp length of warm up period, i.e. number of times, loop is running for HBx calculation
cdil value for cdil in 2-node model of Gagge (applied in calculation of HbEx)
sigmatr value for cdil in 2-node model of Gagge (applied in calculation of HbEx) In case a variable is not given, but necessary for the respective index, a standard value from a list of values is used.
