来自事务所的阐述。车站设计

东京站是这座城市的主要火车站，适用于服务高速火车和地区间的通勤。车站的轨道和旅客站台被抬起，为的是能从西边（丸之内）或东边（八重洲）的人行道进入车站，并穿过首层零售店，进而到达出发列车处。西边入口面对城市的商业区，也是车站历史上有名的入口。相比之下，东边入口则发展较晚，2002年JAHN建筑事务所赢得了邀请设计竞赛，来重新设计新车站入口和侧面的办公大楼。

From the architect. THE STATION
Tokyo Station is the city’s main train station, accommodating both high-speed rail and regional commuter trains. The station’s tracks and passenger platforms are elevated so that pedestrians can enter the station either from the west (Marunouchi) or from the east (Yaesu), pass by ground level retail, and proceed up to their departing trains. The west entrance faces the city’s business district and is the historic entrance to the station. By contrast the east entrance was underdeveloped, and in 2002 JAHN won an invited design competition to redevelop the Yaesu entrance with a new station front and flanking office towers.

两座办公大楼围住了车站入口，形成一个强烈的由八重洲引向丸之内的都市大门，车站入口则位于焦点位置。所有的玻璃立面大厦使用一种全透明“气流立面”，这种立面运用一层15厘米厚的立面间层，在阳光到达建筑表层前吸收和释放能量，利用通透的玻璃来形成高效能的大楼，并且自然采光极佳。在夜晚，两座大楼内部灯火通明，异常夺目，使东京站在城市景观中化作灯塔。

The two office towers frame the station entrance and establish a strong urban gate leading from Yaesu to Marunouchi, with the station entrance as its focal point. The all glass towers employ a fully transparent “airflow façade” that uses a 15 cm deep façade cavity to capture and vent the solar impact before it penetrates the building skin, creating highly energy efficient towers with clear glass, flooded with natural light. At night, the two towers are illuminated from within, becoming lit beacons that mark Tokyo Station in the cityscape.

遮阳棚设计

东京站八重洲重建项目的遮阳棚为车站创造一个崭新的立面。

THE CANOPY
The Canopy at the Tokyo Station Yaesu Redevelopment creates a new image for the station.

对很多游客来说，它是对这个城市的最初和最终印象。尽管处在老车站旁边，它让八重洲区重新定义从丸之内区一直到西边的地段，并使之与众不同。可持续性和低成本维护在遮阳棚的技术中综合体现；在两座变换的大厦中利用一条直线形来体现建筑的简洁设计。234米长的遮阳棚被设计成一个巨大的织物平板，轨迹边缘被固定在一条直线上，由间隔18米不同高度和角度的钢骨架支撑。高度和角度的变化让遮阳棚显得简单而不普通。织物板悬挂在钢架结构上，使得遮阳棚表面形成一个连续的发光平面。结构通过织物表面可以被看得一清二楚，也可以被解读成叶子的经脉，遮阳棚下方的结构为两栋办公楼、车站和零售商店设置了一个二层连接通道。

For many visitors, it is the first and last impression of the city. While standing in contrast to the old station, it defines and distinguishes the Yaesu District from the Marunouchi District to the west. Durability and low-maintenance are inherent in the Canopy’s technology; the simple design is defined as a straight line between two shifted towers. The 234-meter long Canopy is conceived as a large flat textile panel fixed in a straight line at the track edge and supported on steel frames of varying heights and angles spaced at 18-meter intervals. The variation in height and angle gives the Canopy its simple yet distinctive profile. The textile panel is suspended from the steel framework allowing the surface of the Canopy to be a continuous luminous plane. The structure can be seen through the textile surface and is read like the veins of a leaf, while structures under the canopy provide an upper level connection to the two office towers, station, and retail.
