Outline of Final Research Achievements

The purpose of this research is to develop a simple new clo value measuring method. The clo value measurement experiment use "human body and heat flux sensor" and "human body and metabolic analyzer" were conducted. In addition, comparison and examination with the clo value in the thermal manikin were also performed.
Clo value measured by using a human body is smaller than that of by using a thermal manikin who maintained the skin temperature fixedly. The heat loss from the human body was about 60[W/m2] regardless of the temperature difference and clothes. On the one hand, the human body changed skin temperature from 32 ℃ to 29℃. This is because the human body has thermoregulation system. It maybe inevitable that clo value measured by using a human body is smaller than that of by using a thermal manikin who maintained the skin temperature fixedly.
Consideration of clo value measurement method that premised on a thermoregulation system of a human body is needed.
