Research On6E Comprehensive Evaluation System Of Greening Building Materials

Architecture activity has become to one of the most important activities for human's live. Along with the increase of population and the development of economics, building activity developed rapidly, especially on building materials industry. At the same time, this development also brings on a heavy burden to the environment. So the evaluation of whether the building material is good for environment or not, has become to the focus of researching jobs. In this paper, the basic building materials such as portland cement, Construction steel and architectural pottery has been chose to be the research object. Through the investigation and analysis on some building materials enterprises, and refer to the existing buildings and products of greening evaluation methods, the greening building materials6E comprehensive evaluation index system is set up. The weights of evaluation indexes were determined by adopting the Group Analytic Hierarchy Process (GAHP). Based on the current national standards and the analysis of the literature material, the evaluation standard of index level was established by adopting the method of linear interpolation. According to TOSIS method, fuzzy comprehensive evaluation method and the grey relation analysis theory, an improved gray clustering theory model was built as a comprehensive evaluation analysis method. A simple and utilizable software,6E comprehensive evaluation system of greening building materials, was developed by using visual basic6.0programming software. And three kinds of Portland cement, PC32.5R, PO42.5R, Pâ…¡52.5R, of DOCC and DCGC cement plants were evaluated and analyzed by using this evaluation system. The main research work in this paper is as follows:The6E comprehensive evaluation index system which has three layers tree structure has been established based on the research on currently comprehensive evaluation index system and the features of greening building materials in energy conservation, exuberance, easement, environment protection, ecology, economy (6E). The building materials and the enterprises were analyzed by the method of questionnaire investigation based on the6E comprehensive evaluation index system. Limestone equivalent was put forward, and the limestone equivalent of common mineral resources was calculated by keeping the limestone reserves of reference standards. Total resource consumption was expressed by mineral resources limestone equivalent of materials that are consumed in the production. The model of total resource consumption was expressed as The weights of the comprehensive evaluation indexes were calculated by using the group AHP method. The improved tectonic method of judgment matrix was proposed. Firstly, determine the quantitative scale base on the important degree of index in all evaluation indexes. Secondly, structure the judgment matrix according to the ratio of quantitative scale between every two evaluation indexes. The discrimination of judgment matrix indexes has largely improved. In this paper weighted geometric average operator was adopt to gather the judgment matrixes which made by decision makers, the weighted geometric average operator was express as Using a new method which is grey relational analysis to test the consistency of the group judgment matrixes. When the consistency of the group judgment matrixes is not satisfied the requirement, the adjustment method and the model were purposed. The adjustment model was expressed as.According to the analysis and study on the data of national standards, references and national statistical yearbook, the principle and basis of standard level, and the method of linear interpolation, the evaluation index standard level of Portland cement, the construction steel and building ceramics.For the shortcoming of the gray clustering theory model, the improved method was carried out. On the base of consideration the grey relational degree of evaluation index belong to the h standard level and the grey relational degree of the index does not belong to the standard level, the optimal membership degree was introduced to improve the original gray clustering model. Regard Visual Basic6.0as development platform, adopting object oriented programming method, using multi documents interface form design style, a comprehensive evaluation system for greening building materials was developed.
