Thermal Evaluation of Sloping Roofs on Indoor Environment of Traditional Rural Houses in Cold Areas

Abstract

In order to explore the influence of sloping roofs on the indoor thermal environment in cold regions in summer, the article takes the sloping roofs and flat roofs of traditional houses in a county in the cold region of Weinan City as the research object. A combination of theoretical and field measurements was used to analyse the effect of sloping roofs on the internal and external surface temperature of the floor level, indoor temperature and humidity, and comfort in summer. The results show that the existence of sloping roofs largely reduces the surface temperature of the roof and the heat transfer from outdoors to indoors, and can reduce the indoor air temperature by 1.3°C compared to flat roofs, which has a good effect of stabilising the temperature change and keeping the indoor thermal sense in a warm state, and the results of the study can provide a scientific basis for the construction and application of sloping roof houses.
