低影响开发与绿色建筑的雨水控制利用

基于我国绿色建筑评价体系中的雨水控制利用相关内容及现状,论述了低影响开发的理念和关键技术,探讨了在绿色建筑体系应用低影响开发技术的可行性和必要性。举例分析了低影响开发雨水控制利用技术措施在绿色建筑体系中的具体实施方案,以及实施低影响开发理念带来的环境、经济和社会效益。提出在绿色建筑中应将雨水控制利用综合性技术和建筑、景观规划设计及基础设施建设统筹考虑,有机结合。期望为绿色建筑体系中生态环境保护,科学、合理的雨水控制利用提供参考。

STORMWATER MANAGEMENT IN GREEN BUILDING ON THE BASE OF LOW IMPACT DEVELOPMENT

Water efficiency is one of the important criteria in green building initiative.In rural area where sewer lines have not yet reached,the innovative design of on-site stormwater management systems becomes a critical component for green building accreditation.The paper preview the development of stormwater management in green building rating system,introduced the low impact development (LID) content and key technologies,and discussed the feasibility of applying the LID in green building.Several case studies were investigated to illustrate the LID technology using in green building.The results showed that some of these on-site LID practices can reduce runoff annual volumes,and others can remove nutrients in stormwater.So,it is important to integrate the on-site characteristics with landscape planning,design,water recycle,and other infrastructures in green building.
