UTCI—Why another thermal index?
TLDR
UTCI is defined as the isothermal air temperature of the reference condition that would elicit the same dynamic response (strain) of the physiological model of thermoregulation for any combination of air temperature, wind, radiation, and humidity (stress).
Deriving the operational procedure for the Universal Thermal Climate Index (UTCI)
TLDR
The analyses of the sensitivity of UTCI to humidity, radiation and wind speed showed plausible reactions in the heat as well as in the cold, and indicate that UTCI may in this regard be universally useable in the major areas of research and application in human biometeorology.
UTCI-Fiala multi-node model of human heat transfer and temperature regulation
TLDR
An overview of the underlying algorithms and methods that constitute the multi-node dynamic UTCI-Fiala model of human thermal physiology and comfort are provided.

TLDR
An overview of the relevant heat exchange processes is provided, and the relevant parameters (air and radiant temperature, humidity, wind speed, metabolic heat production and clothing insulation), and the relation between clothing material properties and properties of clothing ensembles made from those materials are presented.
Body mapping of sweating patterns in male athletes in mild exercise-induced hyperthermia
TLDR
The present study has provided detailed regional sweat data over the whole body and has demonstrated large intra- and inter-segmental variation and the presence of consistent patterns of regional high versus low sweat rate areas in Caucasians male athletes.

TLDR
In conclusion, individualization of the model allows improved prediction of heat strain, although a substantial error remains.
The effects of protective clothing on energy consumption during different activities
TLDR
Investigation of the effects of a wide range of PPC on energy consumption during different activities found that wearing PPC would significantly increase metabolic rate, disproportionally to its weight, during walking, stepping and an obstacle course.
Resultant clothing insulation: a function of body movement, posture, wind, clothing fit and ensemble thickness
Voor de modelvorming van de effecten van houding, beweging en wind is het belang van de kledinglagen veruit ondergeschikt aan dat van de ingesloten en aanhangende luchtlagen.
Development and validation of the predicted heat strain model.
TLDR
The PHS model would provide an improved basis upon which to determine allowable exposure times from the predicted heat strain in terms of dehydration and increased core temperature.
