摘　　要：针对宿迁23栋典型高层公共建筑用水器具出流特征现场测试及实验室测试,结果表明超压出流带来的用水浪费是一个普遍问题,器具出流量与用水点水压呈显著指数相关关系,支管减压措施在提高用水舒适性的同时能大大节约用水量。建议新建建筑给水系统设计中在合理选择卫生器具的基础上积极采取支管减压措施以降低建筑水耗,对既有建筑可通过给水系统优化进行支管减压改造,促进绿色建筑的发展。Field tests on outflow characters of water using devices were conducted in 6,5 high-rising public buildings in Suqian as well as in laboratory. The results showed that water-wasting caused by over- pressure outflow was a common phenomenon. The flow rate of device was in exponential relationship with the pressure. The pressure-reducing measures would save water greatly as well as improve the comfortability in water-using. It was recommended that under the precondition of reasonable selection of water-using devices, branch pipe pressure-reducing measures should be used in building water supply system to reduce water consumption, which could optimize the current building water supply system to reduce pipe pressure and promote green-building development.
