Research On The Renovation Design Of Passive Solar Houses In Rural Residential Buildings In Northern Henan

China is a large agricultural country.In rural areas,there are many existing buildings,poor indoor thermal environment and high energy consumption per unit area.With the improvement of economic and material conditions in rural areas,the energy consumption per unit area of residential buildings is also increasing rapidly,and the pollution caused by winter heating in rural areas of northern China has been paid more and more attention.It is urgent to study the green heating renovation of rural residential buildings in winter.Based on the design of passive solar house in rural areas,this paper studies the housing in rural areas of northern Henan.Through consulting materials,questionnaires and on-site surveying and mapping,this paper understands the living and production mode of rural residents in northern Henan,and sums up the typical forms and morphological characteristics of local residential buildings.In addition,the digital rendering of the passive solar house before and after the addition of the typical household type shows more intuitively the characteristics of the passive solar house renovation in northern Henan.After comparing and screening the feasibility of several simulation analysis methods,this paper uses Designbuilder software to model and analyze the main houses of typical farm houses in North Henan.The present situation and future situation of typical farm houses in northern Henan are simulated separately after adding thermal insulation layer to their envelopes.Quantitative data of indoor temperature and comfort improvement of passive solar house in winter are obtained,and the advantages and disadvantages of each scheme are evaluated on the basis of these data.Considering the overheating phenomenon of passive solar house in summer,different mitigation methods are given and simulated according to the characteristics of rural buildings in northern Henan.This paper explores the construction strategies of passive solar houses in rural areas of northern Henan,makes analysis and comparison of different schemes in many aspects,obtains quantitative charts and data,and gives targeted evaluation and suggestions.Guided by the policy of "implementing the strategy of Rural Revitalization in an all-round way",I hope this paper can be helpful to the construction and ecological transformation of residential buildings in rural areas of northern Henan in the future.
