RESEARCH ON THE RENOVATION OF ENERGY-SAVING AND ENVIRONMENT-FRIENDLY GREEN HOMESTAY BUILDINGS

In recent years, with the rapid development of rural tourism, homestays have become popular tourist products. However, the shape design of many homestay buildings is unreasonable, and the thermal performance of their envelope structure or materials is poor. How to realize the energy-saving, environmental protection and green development of homestay buildings has become a hot spot in current homestay building design. In this paper, taking a city in southern China as an example, a design plan for an energy-saving and environmentally friendly green homestay building is proposed, based on the thermal environment test and renovation of the homestay building. The research results show that the solar radiation intensity, indoor and outdoor air temperature, and wall temperature of the homestay building are closely related. The temperature on the south wall of the studied homestay building is about 3 degrees C higher than the north wall. When each material reaches a certain thickness, its energy saving rate will increase by less than 1%, and only when its thickness is increased will the energy saving rate increase by more than 1%. The simulation results show that the use of rock wool insulation board is the most beneficial to the energy-saving renovation of homestay buildings. On the whole, the exterior wall renovation plays a key role in the renovation effect of the homestay building, which accounts for more than 90% of the total energy saving effect, while the energy saving effect of roof renovation and door and window renovation is less than 10%. Based on the renovation plan of the homestay building proposed in this article, the energy saving rate of the homestay building in Area A is 33.0%, and the renovation effect is significant.
