柏林波茨坦广场

Potsdamer Platz

波茨坦广场改造（1992年-2002年），欧洲最大的建设项目之一，自柏林墙倒塌两德统一后，由Sony，A&T，Daimler Benz等跨国公司联合投资；将原本没有人烟的隔离区改造成为柏林最繁华的中心区域，成为了柏林新地标。

Potsdamer Platz (1992-2002), one of the largest construction projects in Europe, was jointly invested by the multinational companies of Sony, A & T, Daimler Benz after the fall of the Berlin wall, which transforms the original desert isolation area to the most prosperous center and the new urban landmark of Berlin.

广场及建筑群总占地面积约12万平方米，总建筑面积达80万平方米。设计先后分区分期进行建设了由普里兹克得主皮亚诺，美国知名建筑师赫尔穆特·杨，意大利知名建筑师格拉西分别负责开发的Benz区块、Sony Center及A &T综合建筑群。其中面积最大的Benz区块与Sony Center功能相对混合，集居住、办公、商业与文娱为一体；而A&T综合建筑群功能相对单一，均为办公建筑。

The project covers an area of 120,000m2 and the total construction area reaches 800,000m2. The three zones of Benz zone, Sony Center and A &T buildings are respectively designed by the Pritzker winner Renzo Piano, American famous architect Helmut Jahn and Italian architect Giorgio Grassi. Benz zone with the largest area as well as Sony Center has the complex functions of residential, office, commercial and entertainment, while A & T buildings are only for office.

广场上形式各异、风格迥然的现代建筑几乎囊括了国际一流的建筑师。Benz区块采用了欧洲传统的街坊式布局，在中心广场布置步行区，并添加十分有特色的拱廊街道，而办公楼、住宅、公寓、酒店等则呈带状沿老波茨坦大街分布；控制建筑的尺度，注重公众和私人空间之间的平衡，增加建筑与人的对话，将城市秩序引入生活。而A &T综合建筑群由五个U形、H形和水滴形的块体组合，除了街角水滴形的办公楼高一些外，其他均整齐统一，形象色彩一致，且有向附近空间敞开的小庭院。

Almost all world-known architects at that time had been involved in the design of Postdamer Platz's buildings for various styles and different forms. Adopt the European traditional street block in the Benz Zone, setting the pedestrian area with the featured corridors in the central plaza and along the streets of old Potsdamer Platz distributing the office, apartment, residence, hotel, etc. Strictly control the scale of buildings and stress the harmony between the private and public space to increase the talk of architecture and human and bring the order of city into the life. A & T buildings are made by five U-shaped, H-shaped and drop-shaped buildings with the unified color and form as well as a small public yard.

波茨坦广场的设计最大限度地减少了能量的使用和对环境的污染。建筑物大多数为节能建筑，可以最大限度地使用阳光、风等自然能源，减少能耗；绿化屋顶和非绿化屋顶结合设计，利用绿地滞蓄雨水，即可防洪又可改善生态环境。雨水从建筑屋顶流下，不仅可作为冲厕、灌溉和消防用水，也可流入地面人工湖和水景观，形成雨水循环系统，为城市生活增色添彩。

The design of New Potsdamer Platz minimizes the use of energy and environmental pollution. Most buildings are energy-saving and maximize the use of lights, wind and other natural resources; the combination of green and non-green roofs make full use of raindrops, which flood control and improve the surrounding ecology. The rainwater dropping from the roofs are stored for toilet, irrigation and fire control, but also connected with the artificial lakes and water features to form the water system and color the city life.
