TL;DR: 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.

TL;DR: 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.

TL;DR: The Universal Thermal Climate Index ( UTCI) as discussed by the authors is derived from the Fiala multi-node model of human heat balance and is defined as the air temperature (Ta) of the reference condition causing the same model response as actual conditions.

TL;DR: A clothing model is developed that defines in detail the effective clothing insulation and vapour resistance for each of the thermo-physiological model’s body segments over a wide range of climatic conditions.

TL;DR: The results showed that females chose less insulating clothing in warm conditions compared to males and that observed values of clothing insulation depended on temperature, but also on season and potentially on solar radiation, suggesting that UTCI can serve as a suitable planning tool for urban thermal comfort in sub-tropical regions.
