CALCULATION OF REQUIRED CLOTHING INSULATION (IREQ),DURATION LIMITED EXPOSURE (Dlim), REQUIRED RECOVERY TIME (RT),and Wind Chill Temperature (twc)

IREQ 2008 ver 4.2, Hakan O. Nilsson and Ingvar Holmer.

CALCULATION OF REQUIRED INSULATION, IREQ AND
DURATION LIMITED EXPOSURE, Dlim

M (W/m2), Produzione di energia metabolica (58 to 400 W/m2)
W (W/m2), Rate of mechanical work, (normally 0)
Ta (C), Ambient air temperature (< +10 C)
Tr (C), Mean radiant temperature (often close to ambient air temperature)
p (l/m2s), Air permeability (low < 5, medium 50, high > 100 l/m2s)
w (m/s), Walking speed (or calculated work created air movements)
v (m/s), Relative air velocity (0.4 to 18 m/s)
rh (%), Relative humidity
Icl (clo), AVAILABLE basic clothing insulation (1 clo = 0.155 W/m2K)

IREQ & Dlim RESULTS (minimal to neutral)

Insulation Required, IREQ to (clo)

REQUIRED basic clothing insulation (ISO 9920), Icl to (clo)

Duration limited exposure, Dlim to (hours)

CALCULATION OF REQUIRED RECOVERY TIME, RT

M (W/m2), Metabolic energy production, (normally lower!)
W (W/m2), Rate of mechanical work, (normally 0)
Ta (C), Ambient air temperature, (normally warmer!)
Tr (C), Mean radiant temperature, (normally warmer!)
p (l/m2s), Air permeability
w (m/s), Walking speed (normally lower)
v (m/s), Relative air velocity (normally lower!)
rh (%), Relative humidity
Icl (clo), Available basic clothing insulation, (normally lower!)

RT RESULTS (neutral)

Required recovery time (hours)

CALCULATION OF WINDCHILL TEMPERATURE, twc

v (km/h), Meteorological wind speed (at 10 m)
Ta (C), Ambient air temperature

Wind chill temperature, twc (C)
