Green Degree Evaluation Of Residential Exterior Windows In Qingdao City

Green degree evaluation is an effective method to determine the green extent of theresearch object, The study and application of the green degree evaluation index systemand evaluation methods to the residential exterior windows can help react the greendegree status of the residential exterior windows at various stages, find the methods toimprove the green degree. At present, experts and scholars have done some work on thegreen degree evaluation of the residential exterior windows, but exist followingdeficiencies: the construction of the evaluation system requires in-depth research. Thestudy of the green degree evaluation at present stage only in a certain stage of the wholelife cycle, it fails to fully reflect the green degree of the residential exterior windowsand lacks of data support. The deficiencies of the evaluation index evaluation systemstandards reduce the accuracy and ease of the evaluation. Therefore, a more scientificand rational system and evaluation method for evaluates the green degree of theresidential exterior windows is particularly important.The purposes of this thesis is to determine the green degree of the residentialexterior windows. By the in-depth study of the evaluation methods and evaluationmodels, some results are got as follows:(1) Proposing a relatively complete green degree evaluation index system of theresidential exterior windows. Summarized the incomplete of the existing green degreeevaluation index systemof the residential exterior windows and the status that lacking ofdata support by analyzing and generalizing the thesises and books at home and abroad.On the basis of the whole life cycle theory, this thesis analyed the influencing factors onthe green degree of residential exterior windows. The green degree evaluation indexsystem of Qingdao residential window was constructed from four stages: design andassembly stage, construction and installation stage, the stage of using and the stage ofrecycling and developed the evaluation criteria for each indicator.(2) Using IAHP method to determine the index weight. In order to reduced theimpact of man’s fuzziness on the judgment,this thesis constituted the complementaryjudgment matrix by using interval number.(3) Throuth the classification of the evaluation and the study of the fuzzyrelationship between adjacent grade,this thesis built the membership functions by usingfuzzy mathematics quantified all the indicators of the index system.And established a multi-level fuzzy comprehensive evaluation model on this basis.(4) By the analysis of a case in qingdao city, the experimental results furthervalidated the feasibility and effectiveness of the evaluation system evaluation methodand model in this thesis.
