A Field Study on Thermal Comfort Status of Vernacular Dwellings in Cold Regions of China, Taking Linyi as An Example

Abstract

With the deepening of Chinese rural revitalization in recent years, residents' requirements for indoor thermal environment are increasing. It is widely agreed that the indoor thermal environment of vernacular dwellings in cold areas of China is poor in winter, which seriously affects the thermal comfort and health status of residents. Therefore, in light of indoor thermal comfort improvement, this paper first measured the indoor thermal environment of vernacular dwellings in Linyi City, and found that the indoor thermal environment in winter is very bad, and the indoor thermal environment in summer is relatively comfortable. Secondly, by conducting a thermal sensory investigation, we found that the local residents' adaptability to the local cold climate in winter is greater than that to the hot and humid climate in summer. In addition, to identify residents’ comfort range, we established a scatter plot of the relationship between the ambient temperature and the residents' thermal sensory, which show that the residents' comfort range of 23.3℃~30.0℃ in summer and 11.25℃~17.5℃ in winter. This study compares the current indoor thermal environment of vernacular dwellings with the thermal comfort range of residents from the perspective of users, which can be used as a guide and hopefully these results can provide data support for the future indoor thermal comfort improvement in rural vernacular dwellings in Chinese cold rural areas.
