In recent years, energy consumption in residential buildings account for about 40% of global energy consumption and contribute more than 30% of CO2 emissions. A large proportion of it is used for thermal comfort satisfaction in residential buildings. On the one hand, saving energy only by reducing air conditioning will reduce human thermal comfort level. Therefore, to solve this issue, balancing between energy conservation and thermal comfort is significant. On the other hand, it is possible to estimate human thermal comfort level by analyzing the LF/HF value. Additionally, the heat flow rate between human skin surface and the surrounding air does has correlations with the LF/HF value, which has not been discovered before, this paper shows that there is a possibility to utilize heat flow rate and the LF/HF value to evaluate human thermal comfort level.
