Evaluation of Ecological Environmental Pollution in Green Building Construction

摘要

The long-term extensive development mode of China’s construction industry has resulted in the enormous consumption of energy resources, increasingly severe environmental pollution, and serious ecosystem degradation. Green construction is an essential route to implement the ecological civilization construction policy and achieve green building in China’s construction industry. However, enormous environmental pollution has been generated because of a series of problems in China’s green building construction, such as the lack of a scientific evaluation system for green building construction, loose field construction management, and weak awareness of environmental protection among constructors. Therefore, in this study, a pollution evaluation index system for green building construction was established from three aspects, namely, resource utilization, environmental load, and environmental management, to evaluate the class of ecological environmental pollution triggered by green building construction. Next, a model combining the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation was built, followed by a case study. The results revealed that resource utilization was the main factor causing ecological environmental pollution in green building construction, accounting for 63.70%. Energy conservation and application of new pollution control technology were level III factors that should be given considerable attention. In the fuzzy comprehensive evaluation, the degree of membership of “good” was 0.4855, which was the maximum, indicating that the ecological environment of green building construction in this study was at “good” level, thereby indicating the environmental friendliness of green building construction. This study will be of positive reference values for identifying the ecological influencing factors of green building construction, reducing the waste of resources of green buildings, promoting green construction technologies, and innovating green construction management.
