Research On The Popularization And Application Of German Passive Building Energy-saving Technology In China

German passive building energy-saving technology has always been a leader in the field of building energy-saving.It has been widely used in Germany and other EU regions,and has achieved good energy-saving effects.In 2007,China began to introduce German passive building energy-saving concepts and technologies,but more than ten years later,it is still in the research stage of basic theory adaptability,and the promotion effect is not ideal.Compared with European developed countries,the promotion and application are seriously lagging behind.With the continuous improvement of building energy efficiency requirements in China,passive building energy saving technology has received more and more attention.How to effectively use and quickly promote effective German passive building energy saving technology is an urgent problem to be solved in the field of building energy saving.Based on the slow development of passive building energy efficiency in China,this paper studies the factors that restrict the promotion and application of German passive building energy efficiency technology in China,and seeks to find countermeasures to promote the development of passive energy saving in China.First of all,based on the relevant literature research at home and abroad,the paper analyzes the related issues of the promotion and application of German passive building energy-saving technology in China.Then,comparing the development environment,human environment,building technology and management level and market environment of passive building energy saving between China and Germany,it is pointed out that the German passive building energy saving technology and standards should be adjusted and improved according to different conditions such as climate and development foundation For better application.Next,on the basis of the collation of existing materials and documents,this paper summarizes 21 factors that may affect the promotion and application of German passive building energy-saving technology in China,and divides the influencing factors into society,technology,cost,management according to the category attribute.And five other factors.Through the questionnaire survey and the use of SPSS software,the questionnaire is analyzed using the principal component analysis method,and the relevant policies and regulations,the development cost of the developer,the purchase cost of the consumer,the demonstration leading role of the leading enterprise,standardized design and personalized demand are obtained.Conflict resolution is the five key factors that affect the promotion and application of German passive building energy-saving technologies in China.Finally,based on the successful experience of German passive building energy-saving application promotion in terms of policies,standards,incentive systems,consumer perception,etc.,combined with the problems in the application of actual cases in China,from national and local target setting,policies and regulations Perfection,establishment of fiscal and taxation and market incentive mechanism,demonstration and guidance of typical enterprises,combination of standardized design and personalized choice,etc.,put forward countermeasures and suggestions.The research of the thesis provides reference ideas for the government to formulate policies on the promotion and application of German passive building energy-saving technologies in China,market development of development companies,and standardized production of manufacturing companies.
