Protection And Renewal Of Residential Buildings In Western Mountainous Areas Of Beijing Based On Optimization Of Thermal Insulation Performance Of Enclosure

The building relies on the enclosure structure to enclose the space and divide the indoor and outdoor environment.Therefore,the heat insulation performance of the enclosure structure directly determines the indoor environment comfort degree and the building energy consumption of the building in a certain climatic environment.With the development of the times,the invention of new materials and structural technologies can effectively improve the insulation performance and sealing performance of the envelope structure,and improve the indoor comfort of the building and reduce the energy consumption of the building.The average altitude of the western Beijing mountain area is higher,98.5% is mountainous,and the winter is cold,dry and long.In order to obtain a comfortable living environment,villagers in the mountains have built unique traditional local houses in the west of Beijing based on their long-term summary of production and living experience and traditional aesthetic concepts,combined with the geographical and climatic conditions of the mountains,local conditions,and local materials..The residential buildings in the mountainous area of the western Beijing have thick stone-soil external walls and large window-to-wall ratios.The indoor comfort in winter cannot meet the needs of modern people.This is one of the important reasons for the gradual demise of traditional residential houses.The main factor causing this situation is poor insulation performance and poor air tightness of the envelope.As an important part of the residential buildings,the external protection structure directly affects the indoor thermal comfort.At the same time,the external protection structure is also a comprehensive display of the regional culture of the traditional houses in the western mountain area of the Beijing.Testing and analysis of the protective structure,using modern technology combined with traditional construction experience,summed up and proposed measures to optimize the insulation of the protective structure that is conducive to the protection and renewal of traditional houses.The main content of this study is the thermal insulation performance optimization technology of the traditional residential building envelope in the western mountain area.For several main elements of the external structure,namely the thermal insulation performance optimization technology of the external walls,doors,windows,roofing,and ground,the traditional building materials and The method is combined with new building materials and technologies.Through the comparative analysis of the thermal conductivity data of the envelope structure of differentmaterials and different structural combinations,combined with the previous simulation research results,the insulation optimization technology suitable for the envelope structure of the residential buildings in the western mountain area of the Beijing is studied.The structure of the envelope structure with the best effect and the least impact on the traditional style.The first step of this paper is to take residential buildings in the western mountain area of the Beijing as the research object,select representative villages in the western mountain area for field investigation,and analyze the regional characteristics of the residential buildings in the western mountain area and the existing problems of the surrounding structure;Materials,different construction methods Analyze the principles and characteristics of the thermal insulation of the residential envelope,combined with the current status of traditional residential buildings in the mountainous area of the West Beijing,propose economic,low-tech,regional,and evolutionary as the thermal insulation optimization of the residential envelope Implementation principles;then,for the newly built and renovated residential buildings,the proposed insulation structure optimization implementation plan,combined with the relevant insulation and thermal insulation data comparative analysis,select the most advantageous thermal insulation optimization scheme for the traditional residential buildings in the western mountain area of ??Beijing.Finally,on the basis of this research,the protection and renewal strategy of the traditional houses in the mountainous area of the western Beijing is adapted to the development of the times.
