In order to understand the indoor thermal and hygrothermal environment of the old and new dwellings in the Xihaigu area,two representative old and new dwellings are selected in the winter of 2021 to conduct on-site tests and questionnaire surveys to analyze the thermal environment of different types of dwellings and investigate the reasons for the differences.The results show that the indoor thermal neutral temperature of traditional dwellings in the Xihaigu area in winter is 19.12 ℃(SET*)and the thermal neutral temperature of modern dwellings is 19.48 ℃(SET*).A thermally acceptable temperature range of 17.45~20.8 ℃ for traditional dwellings and 17.26~21.54 ℃ for modern dwellings in winter in the region is derived respectively using 80%of the acceptable and comfortable criteria.The indoor thermal environment and human thermal comfort in Xihaigu in winter are also explored,and thermal comfort comparisons are made with residential houses in other regions to provide a reference basis for improving indoor thermal comfort in Xihaigu in winter.
