Benefit Evaluation of Energy-Saving and Emission Reduction in Construction Industry Based on Rough Set Theory

Abstract Achieving energy conservation and emission reduction in the industry is an inevitable way to promote harmony between society nature achieve sustainable human development. China’s infrastructure construction developing rapidly. Still, there a lack of well-established standard for evaluating potential level construction. A severe quantitative research on energy-saving CO 2 outflow decreases benefits green development advances. This study takes decrease waste slurry treatment Guangdong Province, China, as background, establishes evaluation system with three rule levels: social, economic, environmental, adopts rough set theory determine weights each index ensure objectivity index. According recommendations carbon calculation guidelines, select relevant data evaluate new technology grouted piles road project Province. The results show that saving sector Province are increasing year by year. It’s changes increase or highway mileage, it urgent need investment pollution control. can dioxide industry, also be used reference assess other countries.
