上海世博会伦敦案例馆展示的雨水利用技术案例分析

为实现雨水资源化,满足节约用水的要求,雨水利用技术越来越多地被有节水要求的新建及改建项目所采用,相关雨水利用系统的设计运用越来越广泛。2010年上海世博会伦敦案例馆是单体建筑节能、降耗的典范,雨水利用技术是该项目的节能措施之一,该项目建成已有两年,雨水利用系统运行良好,收集及净化的雨水量大于建筑消耗的水资源耗量,充分发挥了预期的节水的作用,很好地回应了参展方"零能耗"的主题。该文对雨水利用技术在该项目中的具体实施及运用进行了详细介绍,阐述了雨水利用系统的工艺流程、系统组成及设计要点,说明了此类项目在工程具体实施时需注意的要点,对雨水利用系统在单个节能建筑中的设计有着很好的借鉴作用。

Rainwater Utilization Technology Demonstrated in London Case Hall of Shanghai World Expo 2010

Rainwater utilization technology is used more widely by water-saving requirements of new and renovation projects,and the design of the rainwater utilization system is widely applied in water-saving projects.2010 Shanghai World Expo London case is a model for building energy efficiency.The rainwater harvesting technology is one of the energy-saving methods in this project.The project has been completed for two years,rainwater utilization system runs well,water-saving effect is significant.By introducing the appliement and operation processes of the rainwater utilization system in details,the process parameters,system components and design key points were pointed out.Most important things of how to run the system in engineering project was also concluded,which will be a good reference for applying the rainwater utilization system in building energy efficiency.
