结合景观水的绿色建筑节水设计

Water Saving Design of Green Building Combined with Landscape Water

节水与水资源利用是绿色建筑的重要内容。雨水利用能够起到"开源"的作用,同时减少雨水外排、减轻面源污染是"海绵城市"建设的重要组成部分。某绿色建筑项目收集建筑屋面雨水,利用周边的景观水池做为蓄水空间。收集的雨水经过过滤处理后用于周边绿化灌溉及道路冲洗。本设计将景观与雨水利用相结合,契合了"海绵城市"建设提倡的蓄水及雨水利用方针。

Water saving and water resource utilization is an important content of green building. Rainwater utilization can play the role of “ open source ” while reducing the efflux of rainwater and alleviating the pollution of the surface source,that is an important part of the “ Sponge city” construction.The green building projects to collect roof rainwater and use the surrounding landscape pool as a water storage space. The collected rainwater is filtrated for the surrounding green irrigation and road washing.The design combines the landscape with the rainwater utilization,which is in conjunction with the water storage and rainwater utilization policy advocated by the “ Sponge city” construction.
