This paper mainly aims at the characteristics of rural areas,where heating energy consumption is high and the environment is poor,and the effect cannot be guaranteed.Based on this background,this paper studies rural heating and how to set external walls reasonably and other means to reduce energy consumption.Taking a typical farm house in Shandong Province as the research object,the building energy consumption simulation software DeST-h was used to simulate the building energy consumption before and after different window wall ratio and additional sunlight.The results show that the north window wall ratio is positively correlated with the heat load,and has a greater effect on the cooling load in summer.The addition of additional sunlight room can effectively increase the basic room temperature and reduce the building energy consumption.When the window to wall ratio is 0.2 and the sunlight room depth is 1.2,the annual cumulative cooling and heat load energy-saving rate reaches 22.8％.The research results can provide reference for improving the design code of rural building energy efficiency.
