绿色建筑评价中节水和水资源利用指标的比较及启示

Comparison of Water Saving and Water Resource Indicators in Green Building Assessment and Its Enlightenment

自从国家住建部推出《绿色建筑评价标准》(GB/T 50378)以来,获得绿色建筑评价设计标识和运营标识的项目数目已超过13000个。同时,一些国际上影响较大的绿色建筑评价标准也进入中国,虽然同样注重建筑的可持续发展,但由于不同国家对各类资源的重视有别,考量的建筑阶段不同,这些评价方法并非完全相同。新国标(GB/T 50378-2019)的编写参考了美国LEED、英国BREEAM、德国DGNB、日本CASBEE、澳大利亚NABERS标准中的部分内容,笔者将几种评价标准列出进行比较,重点是节水和水资源利用方面的对比。

After the Ministry of Housing and Urban-Rural Development of China publishing the Evaluation Standard for Green Building GB/T 50378,over 13,000 projects have obtained the Green Building Evaluation Design and Operation Label.Meanwhile,overseas assessment standards have also been gradually introduced into China.Although the different standards pay attention to the sustainable development of the buildings,they are not exactly the same as different countries focus on different resources and evaluate the buildings in different stages.As the new GB/T 50378-2019 made references to assessment standards from other countries,such as LEED,BREEAM,DGNB,CASBEE and NABERS,this paper compares it to its overseas counterparts on the aspect of water saving and water resource utilization.
