Research On Construction Site Layout Evaluation System Based On Green Construction

With the rapid development of the construction industry,it brings huge energy consumption and the status of serious environmental pollution increasingly attracted people’s attention,in order to improve this situation,sustainable development concepts into the construction sector,the construction industry to achieve sustainable development becomes an inevitable trend,but to achieve the sustainable development of the construction sector,you have to implement the concept of sustainability in the whole life cycle of the building,green construction is to introduce sustainable development in the field of construction,the construction phase is caused by environmental pollution and waste of energy with the main phase of green control at this stage there is very important,and one from the construction preparation stage if it is controlled,will be conducive to the smooth progress of the entire construction phase,to achieve green goal,this paper carried out the construction of green layout evaluation studies,the establishment of a scientific and rational evaluation system.Firstly,the current development of green construction and green construction assessment to start,through a lot of literature reading and analysis of research in green construction field were basic understanding,discovery of the construction layout of green evaluation little while construction layout as an important part of the smooth construction of the guide,it carried a green evaluation studies for achieving green construction is necessary,then the proposed research direction,namely green construction evaluation system layout,followed by the first Chapter Ⅱ of the theory in-depth interpretation,first analyzes the connotation of sustainable development,because green is the construction of sustainable development of specific applications in the field of construction,green construction layout of a preparatory phase of green construction,so the definition of green construction layout should be based on a sustainable development dimension,sustainable development requires not only achieve a natural,economic and social unity,as well as different spaces,the coordinated development of different times,on the definition of green construction may well reflect this sustainable development,in order to maximize the social,economic and environmental benefits of comprehensive construction philosophy,based on these theories,put forward the concept of green construction layout not only requires a reasonable construction layout to improve efficiency,reduce costs,but also to meet the energy saving and environmental protection,people-oriented,comprehensive,dynamic control over land claims,while the guidelines set forth green construction layout from the economic,social and environmental benefits in three areas.Also in this chapter also the method of green construction layout evaluation model involved in the analysis and selection,select the analytic hierarchy process according to the paper established the index system characteristics to determine the index weight,choose the fuzzy comprehensive evaluation method evaluation of green construction layout.Chapter Ⅲ Based on the above study,we constructed the index system of green construction layout evaluation,divided into target layer,criteria layer and project layer,the target layer is the green construction layout evaluation,guidelines layer is divided into six indicators,project layer,respectively this refinement of the six indicators,proposed 23 indicators that are quantitative indicators and qualitative indicators combining comprehensive coverage of the construction layout of content,and each indicator developed a corresponding evaluation criteria,entered the fourth chapter of the evaluation model calculation of the index weight,the establishment of green construction layout evaluation model using fuzzy comprehensive evaluation method,thus the theoretical basis of all built,in the fifth chapter of a commercial and residential building construction plan arrangement as an example,the set-up phase,Analytic hierarchy Process green construction layout evaluation to verify the feasibility of the model.In this paper,the evaluation of both quantitative indicators but also qualitative indicators,and because few studies,limited information,select the index has some uncertainty and ambiguity,this paper re-evaluation methods to identify and select indicators on the right.Select the analytic hierarchy process and fuzzy comprehensive evaluation method to evaluate the establishment of a more scientific and reasonable layout of green construction evaluation model,on the one hand to make up for the lack of research in this area,it also hopes to guide the construction site of the plane arrangement,to achieve sustainable development in the construction phase of the application layout,reasonable construction layout can not only reduce costs,but also to ensure the smooth progress of the whole construction process,but this study,there are some shortcomings,evaluation index system the qualitative indicators above normal,and fine enough to set the evaluation criteria,in addition to the calculation and evaluation indicators has experts to complete,there is a certain subjective preferences influence the objectivity of the evaluation results will be reduced,hope can continue to be carried out in future research perfect.
