Spraying Type Environmental Protection Wall-original Bamboo Keel Residential Of Energy Saving Design And Scheme Comparison

As a new type of green building,the spray-painted environmental-friendly walloriginal bamboo keel house can not only meet the use requirements of rural and rural residential structures,but also achieve the purpose of energy conservation and environmental protection.The popularization of the structure system can accelerate the realization of energy conservation and emission reduction and solve the problem of urban construction waste.However,the current energy-saving design of the building envelope is the weak link in its promotion.Based on this,this paper studies the energy-saving design and scheme comparison of the envelope structure with spray-painted environmental protection wall-original bamboo keel residence.The main research contents of this paper are as follows:Firstly,based on the concept of energy conservation design of envelope,the research scope was defined.At the same time,the energy-saving design technology of outer wall,roof and outer window of the outer protection structure was analyzed in detail.The advantages and disadvantages of different insulation measures and the performance characteristics of insulation materials were obtained.The energy consumption analysis method based on DeST-h was determined by comparing the energy consumption analysis method and the energy consumption simulation software.Secondly,the influence factors of energy conservation design of envelope are analyzed.Through the analysis of the energy conservation design of the envelope in different parts of the structural system,the energy conservation design scheme of the envelope was determined.Orthogonal test table was prepared by orthogonal test method,and energy consumption analysis was carried out by DeST-h simulation software.By comparing and analyzing the influence of different parts of building envelope on building energy consumption and the influence of different parts of building envelope parameters on building energy consumption,the optimal combination scheme of energy conservation design of building envelope with single index of building energy consumption was obtained.Finally,total operating load of the building,cost of building palisade structure and cost of energy consumption in economic evaluation index as optimization index of energy saving design were selected and calculated.Based on orthogonal test table,using objective weight-grey correlation analysis method,respectively,calculated the grey correlation degree and the weight of each performance index.According to the grey correlation degree,the multi-objective comprehensive evaluation optimal combination scheme of spraying type environmental protection wall-the original bamboo keel residential was obtained.Based on the demonstration project,the feasibility of the energy saving design of envelope and selection of energy saving design scheme of envelope were verified.
