'The Bow' Office Building

加拿大城市卡尔加里最近刚刚建成了一座“弓”形写字楼，由国际知名事务所Foster＋Partners设计，成为这座城市的第一高楼。这座237米高的写字楼通过几个设计策略，最大化地减少能源消耗，融入城市现有的基础设施，为用户提供最舒适的环境。一层与外面的公共活动广场和步行道相联系，最终与整个城市的道路网相通。这里有商店、餐厅和咖啡馆等，为社区提供了社交场所；上层则主要是出租给各种公司的办公空间。建筑平面的弧形是为了保证一些结构上的优越性。弓形凹的一侧向南，让室内接受更多的自然光和，还能看到远处的落基山脉。内部有部分墙壁楼层被抵消，形成了三个六层高的空中花园，分别在24、42和54层。这些绿地作为热缓冲层，只能从办公空间这边进入，有利于用户之间的交流合作。凸的一侧主要用来抵挡风，由于这个几何形状本身就可以承受侧向力，所以大大减少了建筑所需钢结构强度。建筑外表暴露的三角网格跨越6层，在人的尺度范围内，从视觉上打破高耸的结构。
事务所高级合伙人Nigel Dancey介绍说，这栋高楼的形态来自卡尔加里独特的气候条件。建筑坐北朝南，有六层高的空中花园、咖啡厅和会议区，营造出舒适的办公空间。在建筑底层部分，有15条封闭的桥连接到市中心的商店、咖啡馆和广场，与城市活动相渗透。这个建筑的每个方面，包括架空的楼层和斜肋网格，都设计得十分高效。建成后，这个弓形写字楼就成了卡尔加里市新的象征。

Calgary has just welcomed the tallest addition to its skyline， 'the bow' office building by internationally-renowned practice Foster + Partners. The 237-meter high tower implements several design strategies to reduce the structure's energy use and provide maximum comfort while integrating into the city's existing infrastructure. The ground floor is connected to the public realm through an exterior plaza and the covered walkways that stretch throughout the urban grid. Shops， restaurants and cafes offer a social public atmosphere for the community， with office spaces above serving various companies. The general form follows that of an arc segment in footprint which affords several structural advantages. The concave side faces south to accept natural sunlight and frames undisturbed views of the Rocky Mountains. The curtain wall has been offset from the floor planes opening up a series of atria and three six-storey sky gardens located at the 24th， 42nd， and 54th floors that create a thermal buffer as well as promote interdisciplinary collaboration， being the only access points to each office unit. The convex side stands to break through the prevailing winds， greatly reducing the amount of steel needed in the structure as the geometry itself helps to withstand the lateral force. An exposed triangulated mesh spans 6-storey bays and helps to visually break down the towering structure to a more sensible human scale.
Nigel Dancey， senior partner of Foster + Partners states: 'the tower’s form was shaped by the unique Calgary climate – facing south， the building curves to define a series of spectacular light-filled six-storey atria， with mature sky gardens， cafes and meeting areas， which bring a vital social dimension to the office floors. This principle extends to the base of the tower， which is highly permeable， with a +15 enclosed bridge connection to downtown， an atrium of shops and cafes and a fantastic new plaza. Every aspect， from the raised floors to the diagrid structure， is designed to be highly efficient. The bow is a bold new symbol for Calgary， and is testament to the strength of our team and excellent local relationships.'
