Research on the Evaluation of Ze-ro-Carbon Community Construction Based on Entropy Weight-Grey Corre-lation Degree Analysis
Since the"Double Carbon"goal was put forward,various cities and towns in my country have ac-tively taken measures to save energy and reduce carbon.As the core unit of urban life,urban communities play an important role in the field of energy conservation and emission reduction.Zero-carbon community construc-tion is the basis for achieving the"Double Carbon"goal.There are some problems in the existing community zero-carbon construction index system and evaluation standard in China,so it is urgent to establish a set of scientific and effective evaluation index system suitable for the actual situation in China.Based on a review of the research and practice of low carbon community indicator systems at home and abroad,combined with the construction of low carbon community evaluation indicator systems and relevant zero-carbon indicator docu-ments,a set of evaluation indicators was selected through a questionnaire survey method to determine 8 pri-mary indicators and 29 secondary indicators of carbon performance,green buildings,energy systems,green transportation,carbon sinks and carbon management,waste treatment,water resource utilization,and resi-dents'zero-carbon lifestyle,and then combined with the entropy weight method and the grey correlation mod-el.The evaluation method system and evaluation standards for zero-carbon communities are proposed,and the indicator system is applied through empirical research.The final results show that carbon performance and energy system have a greater impact on the construction of zero-carbon communities.Direct control of carbon emissions and indirect use of green energy saving buildings and renewable energy are more effective in reduc-ing emissions and also play an important role in evaluating zero-carbon communities.The evaluation system and evaluation standards obtained in this study provide a set of reference for the construction and rating of ze-ro-carbon communities,and also provide solid theoretical support for the construction of zero-carbon commu-nities in the future.
