摘要:在新世纪，建筑给排水将担负新的历史重任，面临新的挑战。建筑给排水将更突出以人为本的原则，并将重点调整到民用建筑与工业建筑并重，公共建筑与居住建筑并重，冷水供应与热水供应并重，走上全面、均衡、务实、安全的发展之路。建筑给水排水属于应用工程，是整个建筑设计中一个相当重要的环节，也是建筑设计中必不可少的。

   本文主要为高层办公楼给水排水设施和消防系统的设计。其中，给水系统为分区供水，高区采用水箱供水，为上行下给式，中区采用水泵直接加压供水，低区由市政管网直接供水；建筑内部生活污水采用分流制排出；室内消防设计按一类高层建筑设计，自喷采用面积作用法计算，按中危险级设计。

Abstract:In the new century, building water supply and drainage would assume the historical responsibility, and facing new challenges. Building water supply and drainage will be more prominent to the principle of people-oriented, and focus adjustment to both civil construction and industrial buildings, both public buildings and residential buildings, both cold water supply and hot water supply, embarked on a comprehensive, balanced, pragmatic and safe development of the road . Building Water is an application works, is a very important part of the whole architectural design, architectural design essential

 This article mainly shows design water supply and drainage design in a official occupancy building. In this water supply system supplies water to high region and low part ,the high level tank supply system of high region ,submit to higher author it all the high region , municipal water distribution system direct supply low part ;live drainage discharge adopt separate system in a building ，according to the high-riseⅠ type designing the interior fire prevention system; automatic water sprinkler system calculate of area, adopt medium perilous Ⅱ.
