| Construction industry is a typical high energy consumption and high emission industries, the green building is involved in the realm of more deep level of sustainable development, to develop green building is of great urgency. Establishment of a scientific and effective green building evaluation system plays a vital role on the promotion and implementation of green building.As the starting point, this paper introduces the current situation on building energy consumption and the promotion of green building, described the significance on establishing green degree evaluation system; proposes the principles and ideas for index evaluation system, this paper establishes the evaluation index system of green degree based on analyzing the meanings such as ecological and economic equilibrium degree, regional coordination degree in society, operating comfort degree and mechanisms of green-degree which covered by building green degree; based on life cycle assessment theory, ecological economic optimization theory and ecological footprint theory, combined with the right entropy method, analytic hierarchy process, Delphi method, the weighted set-valued statistical method, Determine the indicators value,weight and evaluation of the quantitative and qualitative indicators, at last reach the building green degree.To confirm the effectiveness of the evaluation index system of green degree and the Fuzzy Comprehensive Evaluation Method, and test its operability in residential energy conservation, the paper analyzes a residential district in Nan'an district of Chongqing as a real example, based on the results of energy-saving housing, demonstrates the science and feasibility of the evaluation system.Owing to its flexibility, evaluation system can be applied on building's assessment in different regions, it can be used for the optimization in the design phase, as well as on the Building Project Evaluation, provides experience for the development of the Green Building Evaluation System. |
