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.
