JWACA2023-040: Study on Influencing Factors of Therma Comfort Based on Individual Differences

Abstract

Human individual differences affect thermal comfort extensively and significantly, and creating a comfortable and pleasant thermal environment requires a large amount of energy. In order to study the change rule of human body to thermal environment according to different groups, on this basis, to provide comfortable thermal environment for different groups of people and realize building energy conservation scientifically. This paper summarizes the individual difference factors affecting indoor thermal comfort by combing the research process and results of existing literatures. It is found that gender and age are the main factors affecting human thermal comfort, followed by body shape and adaptability. Women, the elderly and outsiders (those who have not adapted to the local climate) are more picky and sensitive to deviations from the optimal environment than men, young people and locals, while men tend to feel heat more easily. In addition, obese individuals were more uncomfortable in hot conditions, but more resistant to cold conditions. It is also found that the differences in clothing behavior and physiological response are the most likely reasons to explain the differences in thermal comfort requirements between groups and individuals.
