Study on the thermal environment of rural residential buildings in winter in the Guanzhong region of Shaanxi

In order to study the thermal environment of rural dwellings in cold areas,the physical environment of rural dwellings in the Guanzhong region was taken as the research object.The thermal environment parameters,such as indoor and outdoor temperature and humidity,wall surface temperature of existing dwellings were measured,recorded,and analysed using physical environment measurements and numerical software simulations.By using Ecotect Analysis software to optimize the building envelope of existing residential buildings,the thermal analysis shows that the optimized building envelope reduces the heat transfer coefficient,increases thermal insulation,reduces building energy consumption by 59%,and increases the human comfort PMV from -2.01 to -1.40.These findings provide theoretical and data support for the construction of rural dwellings in cold regions and for research into thermal environments.
