Transformation of Rural Low-Carbon Houses Under the Guidance of Thermal Comfort: A Case Study of the Xuzhou Area

In the process of deepening the strategy of rural revitalization in China, the transformation of rural houses is an important part of promoting rural revitalization. Rural houses are the living places of the majority of rural residents, and there have been problems of poor thermal comfort and high energy consumption in the Xuzhou area for a long time. At present, the starting point of domestic research on the transformation of rural houses is mostly single-objective optimization of thermal comfort or energy conservation, and few studies involve these two aspects at the same time. In this study, based on field investigation, questionnaire surveys, software simulation, orthogonal testing, and other research methods, an adaptive thermal comfort model for rural residents in the Xuzhou area was established, and the factors affecting the indoor thermal comfort and energy consumption of the rural houses were simulated. In order to jointly improve indoor thermal comfort and reduce energy consumption in rural houses, an optimal transformation scheme suitable for existing rural houses in the Xuzhou area was proposed. By comparing the data of indoor thermal comfort and annual energy consumption of a typical rural house before and after the transformation, and then estimating the cost required for the transformation of the house, the advantages of the transformation scheme in terms of effectiveness and economy were verified.
