Based on the investigation and testing of existing residential rural buildings in Ganzi and Aba prefectures,this paper analyses the architectural layout characteristics and current situation of the envelope of the existing residential rural buildings,and simulates the effects of additional sun buildings and corresponding energy-saving measures on the winter temperature improvement and energy saving of the residential rural buildings.The results show that the typical daily indoor temperature of the residential rural buildings on the Western Sichuan Plateau in winter can be increased by 2 to 5 ℃ by additional sun houses and adopting energy-saving measures such as adding insulation curtains,laying coatings,and replacing double glazing,the heating load can be reduced by about 36.5% to 57.2%,and the solar radiation utilization rate can reach 14%.
