Research On Energying-saving Retrofitting Design Of Rural Housing In North Henan On Energy Consumption Simulation

Number of existing buildings in rural areas has less insulation measures,and indoor thermal environment is poor.With the development of the rural economy and improvement of farmers' living standards,highlights the rural indoor comfort issues.To improve the rural living environment and solve problems of rural residential energy-saving technologies,according to the characteristics of north of Henan rural buildings forms developed energy-saving programme is a great significance for the sustainable development of building energy saving in our country.First,this paper takes the rural residential in the north of Henan Province for main research object,conducted a field research at 10 villages of 73 households in Anyang,Xinxiang,Jiaozuo.Through the questionnaire,the indoor temperature measurement and plotting for local forms of village layout and courtyard,living habits and modes of production,general construction,heating and cooling and the indoor thermal comfort conditions,analyzes the reason for the poor indoor thermal comfort of rural housing,and summarized the typical form of rural housing.Secondly,by using ECOTECT software to simulate the typical building.Under the control of other factors unchanged,analyses a part of a single variable,including the roof,wall,window and other parts of the building envelope thermal performance and the application of passive technology,compare tht heat consumption indexes and thermal environment index before and after the energy-saving reconstruction,and put forward suitable energy-saving measures for Yubei rural building.Finally,according to the principles of building energy-efficient design,putforward a comprehensive suitability technology optimization strategy.Finally,develop a reasonable energy-saving optimization scheme for single-layer flat housing and single slope housing and compare before and after the energying-saving building energy consumption rate.Aim to provide a reference for energy-saving renovation of local rual existing buildings.
