温哥华新交易大厦
The Exchange / Harry Gugger Studio

由专筑网李韧,杨帆编译

来自建筑事务所的描述:四面环绕着山水的温哥华具有独特的城市景观,这些景观主要由自然元素而形成。

交易大厦位于温哥华市中心。作为城市中心商务区的高密度集中办公场所,这对于周围地区乃至整座城市来说,都具有极高的经济价值和宝贵的就业机会。

Text description provided by the architects. Surrounded by water and framed by mountains, the unique urban cityscape of Vancouver’s downtown is defined by its spectacular natural setting.
‘The Exchange’ is located in the heart of this downtown area. As one of a select few new, high density, office developments in the city’s central business district this new tower will bring valuable diversity, revenue and jobs to the neighbourhood and to the city as a whole.

新办公塔楼的设计来源于周边的城市肌理与自然环境,尤其是即将进行现场改造与修复的老式证券交易大楼。这座精致、美观、优雅的建筑四周环绕着垂直壁柱,壁柱与建筑高度相契合,同时也让建筑更好地融入城市的街道景观。

The design rationale for the new ‘Exchange’ tower is entirely derived from its surrounding context and environment; in particular the existing Old Stock Exchange building, which is to be preserved and rehabilitated on the site. This refined, handsome and elegant building has facades of carefully composed vertical pilasters that are designed both to best accentuate its height and at the same time ground the building within the streetscape of the city.

新塔楼没有在视觉上一心占据主导地位,它与老建筑的关系更多在于相互辉映,而非竞争,这使得整个城市构图更加完整,人们能够非常直观地感受到温哥华具有历史气息的未来发展趋势。

The new tower does not attempt to dominate or compete with this prominent original building but rather to successfully work together with it in order to create an overall composition that looks at once to Vancouver’s future without obscuring its past.

建筑师将体块有序地打断,还将原有建筑的周边场地部分留出,这座新建筑仍然保持了老建筑占据街道景观主导地位的优势,从而保留并确认其优越的地理位置。

By both breaking up the mass of the tower over its entire height and by recessing its bulk from the perimeter of the site above the Old Stock Exchange, the new building allows the existing structure to fully define the streetscape, retaining and confirming its proud position within the heart of Vancouver’s downtown.

由于塔楼的形式较低,从而更好地呼应了原有建筑,并让老证券交易所保持其独立性,因此,为了在建筑上部空间的设计中将场地的潜能发挥到最大,建筑师将上部楼层尽可能开放,并且通过层层递进的形式让塔楼从不同的方向都具有更加开阔高效的楼层空间。这些楼层在建筑的两侧形成向外突出的体量,这也让办公人员可以更好地欣赏城市周边的美景。

As the form of the tower retreats lower down to better define the original form and independence of the Old Stock Exchange, it consequently grows higher above to maximize its potential on the site. Here at the upper, more valuable floor levels, the tower steps out in two directions to provide larger, more efficient floor plates. These steps consequently create terraces on the tower’s sides that are optimally positioned to exploit the best views of the surrounding city and the dramatic panorama of the mountains beyond.

而在塔楼的形体设计中,建筑师不仅采用了倒阶梯状体量,还将体量的边缘进行倒角处理,从而削弱乐整个建筑的体量感,同时也降低了塔楼对于周围环境的影响,同时也保证了老证券交易大厦在街道中的主导地位。

The stratification and stepping of the tower’s form, coupled with the chamfering of its corners both reduces its overall bulk and impact on its neighbours and leaves the Old Stock Exchange building as the single-largest element on the site, emphasizing its presence within the city centre.

高层建筑对于城市的天际线多少有些影响,新交易大厦在城市空间里形成了独特的标识。从街道上看,其悬臂式结构体量成为温哥华商业中心的一大特征。如果从城市的不同角度欣赏这座建筑,其各个元素都能够与周边建筑相互呼应,但又明显拥有自身的特色。

Restricted from creating a strong intervention on this skyline, ‘The Exchange’ instead looks to create a distinctive icon within the space of the city itself. Viewed from the street, its cantilevered form creates a unique identity for the tower at the centre of Vancouver’s business district. Seen in-the-round ‘The Exchange’s’ form is different from all angles yet remains identifiably the same coherent structure, clearly distinct from its neighbour’s and further pronouncing its individuality and historical pedigree.

对于建筑和原有建筑历史性的尊重是现有建筑立面设计的出发点。新交易大厦的立面运用了由铝框架构成的细条纹垂直元素,从而与老式证券交易大厦的立面形态交相呼应。这个统一的系统在建筑场地中被保留下来,同时也强调了塔楼自身的垂直性,使得建筑在不同的角度均呈现优雅自然的外观形态。

A respect for the architectural and significant social heritage of this original building is also paramount to the origins and identity of the tower’s façade design. The strongly vertical nature of the Old Stock Exchange’s façade is echoed in the elegant pinstripe of the tower’s external aluminium mullions. This unified system responds to the solid pilasters of the Old Stock Exchange Building that is to be retained on the site whilst accentuating the verticality of the tower itself, defining a more uniform and slimmer overall appearance of the building from all orientations.

垂直框架系统同样具有功能性,它对于建筑的围护结构起到了遮阳的作用,并且能够有效降低建筑的制冷负荷需求。建筑中的被动式设计效应也大大改善了塔楼与其周边建筑的隐私性。

该项目由Harry Gugger Studio与Iredale Group Architecture共同合作完成。

The vertical mullions perform a further function, shading the building envelope and significantly reducing its cooling load requirements. Their passive screening effect also greatly improves the visual privacy between the tower and its immediate residential neighbour, Jameson House.
