既有办公建筑绿色三星改造工程给排水设计

The Design of Water Supply and Drainage System for Third-Star Green Building Renovation Project of the Existing Office Buildings

为推进生态文明建设和落实住建领域碳达峰碳中和目标要求,实现城乡建设绿色发展和建筑业转型升级,结合城市有机更新的既有建筑绿色化改造越来越多。本文以某高层旧办公楼改造工程为实例,针对该工程给水系统、消防系统、雨污水系统等方面的绿色设计及改造方案进行介绍及分析。以实际情况提出绿色三星改造解决方案,包括办公建筑采用无负压变频给水设备,水表分级计量,合理升级消防设施,收集回用屋面雨水,全面更换节水型卫生器具,微喷灌、滴灌节水灌溉方式等。

In order to promote the construction of ecological civilization,to implement the carbon peak and carbon neutrality in the field of housing and construction,and to achieve green development of urban and rural development and the transformation and upgrading of the construction industry,the transformation of the existing buildings combined with urban organic renewal is increasing.Taking the reconstruction project of an old high-rise office building as an example,the paper introduces and analyzes the green design and transformation scheme of water supply system,fire fighting system and drainage system of the project.According to the actual situation,the solution to the third-star green building renovation project is proposed,including office buildings using no negative-pressure frequency conversion water supply equipment,water meter grading metering,reasonably upgrading fire control facilities,collecting recycled roof rainwater,comprehensively replacing water-saving sanitary appliances,micro-jet irrigation,drip irrigation,water-saving irrigation methods,and so on.
