既有公共建筑三星级绿色改造案例分析

Case analysis on the three star green retrofitting of existing public building

既有建筑的绿色改造,对提高建筑的安全性、舒适性和环境友好性,转变城乡建设发展模式,具有重要的意义和作用。本文通过对四川省首个既有公共建筑绿色改造三星级标识项目的技术措施和增量成本的介绍和分析,阐明了既有建筑绿色改造的技术路径,并说明了绿色建筑的实际增量成本通常远低于统计数据。本项目的顺利实施,将扭转大众对绿色建筑高增量成本的错误认知,为大量既有建筑的涅槃重生提供新的思路和技术参照。

The green retrofitting of the existing buildings is of great significance and effect in improving the safety,comfort and environmental friendliness of the building. Based on the technology and cost analysis of the first three-star green retrofitting building in Sichuan province,this paper identify the technical path to green retrofitting of existing buildings and show that the actual incremental costs of green buildings are generally well below the statistical data. The project has set a new benchmark for the development of the existing public buildings.
