摘要:在新世紀，建筑給排水將擔負新的歷史重任，面臨新的挑戰。建筑給排水將更突出以人為本的原則，并將重點調整到民用建筑與工業建筑并重，公共建筑與居住建筑并重，冷水供應與熱水供應并重，走上全面、均衡、務實、安全的發展之路。建筑給水排水屬于應用工程，是整個建筑設計中一個相當重要的環節，也是建筑設計中必不可少的。

   本文主要為高層辦公樓給水排水設施和消防系統的設計。其中，給水系統為分區供水，高區采用水箱供水，為上行下給式，中區采用水泵直接加壓供水，低區由市政管網直接供水；建筑內部生活污水采用分流制排出；室內消防設計按一類高層建筑設計，自噴采用面積作用法計算，按中危險級設計。

關鍵詞 高層建筑；給水；消防；排水；熱水

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.
