Study on energy saving reconstruction of the outer protective structure of residential buildings in Tongliao rural pastoral area,Inner Mongolia
In order to improve the indoor thermal environment and reduce energy consumption of residential houses in Tongliao rural pastoral area of Inner Mongolia,three representative residen-tial houses are taken as research objects to measure indoor and outdoor temperatures in winter and analyze the energy saving problems of residential houses.The single factor energy-saving transformation and orthogonal experiment combination energy-saving transformation are carried out for the factors affecting energy consumption,such as external wall insulation,roof insulation and exterior window type.The range method is used to explore the influence degree of each factor on the experimental index,with the best scheme selected based on the energy saving rate and eco-nomic analysis.The research shows that the external wall insulation has a greater impact on the three residential buildings.The best renovation plan is 50 mm thick EPS insulation board for the external wall,60 mm thick EPS insulation board for the roof,and 6 mm+12 A+6 mm ordinary insulating glass for the external window.After the renovation,the annual cumulative heat load of the three residential buildings is reduced by 53.58％,45.05％and 43.55％,respectively.The research results can provide a basis for the improvement of indoor thermal environment of resi-dential buildings in rural pastoral areas of Tongliao,Inner Mongolia,and provide a reference for the energy-saving transformation of the outer protective structure of residential buildings.
