德国复兴信贷银行Westarkade是全球最高的高层办公楼之一,每年建筑运行所需要的初级能源不足100 kWh/m2。这座15层高的德国复兴信贷银行集团总部扩建建筑坐落在法兰克福市西部边缘,与中央棕榈园相邻,是对原有建筑群的补充,原有建筑建于20世纪70年代、80年代和90年代,新建筑包括会议设施以及可容纳700人的办公空间。

这座高56米的高层建筑的体量与原有的塔楼群融合在一起,所有建筑的天际线从Zeppelinallee都可见,另外从这些办公空间也可以相应地看到外面的景色。同时,这座新的高层建筑也成为两个不同城市空间之间的连接界面:从街道上看,建筑呈现纤细的板楼形态,而在另一侧,它是棕榈园景观不太显眼的背景。建筑基座流线型的外形界定了街道的边缘,采用了旁边北侧骑楼建筑的檐口高度。沿街一侧的立面在一层向内缩进,形成了有顶的拱廊,而棕榈园景观则被无缝地融合进基地后面,创造了宽敞的开放空间。

新建筑在材料与颜色上扩展并补充了原有的建筑群。双层抗风压立面保温值很高,可以提供自然通风,不受天气的影响,还可以提供高效的遮阳作用。热辐射楼板与地热有助于进一步降低能耗。

德国复兴信贷银行Westarkade获得了芝加哥高层建筑与城市人居委员会(CTBUH)颁发的“2011年世界最佳高层建筑奖”。

The KfW Westarkade is one of the first high-rise office buildings worldwide that can be run on less than 100 kWh/m2 of primary energy per year. Situated in the city’s West End adjacent to the central Palmengarten park, this 15-storey extension to the KfW Banking Group’s headquarters completes an existing ensemble of buildings from the 70s, 80s and 90s, and contains conference facilities as well as office space for some 700 people.

The volume of the 56 metre high building has been integrated within the cluster of existing towers in such a way that the skyline of these buildings remains visible from Zeppelinallee while, correspondingly, views out from these offices are maintained. At the same time the new high-rise acts as an interface between two distinct urban spaces: while appearing as a slim slab towards the street, it presents a discreet backdrop to the landscape of the Palmengarten. The flowing form of the building’s socle defines the edge of the street, taking up the eaves height of the neighbouring North Arcade building. The façade is set back at ground level to create a protective arcade to the street, while the landscape of the Palmengarten is drawn seamlessly into the rear of the site to create a generous open space.

The new building extends and complements the existing ensemble in both materiality and colour. The double-layered wind-pressurised façade has high insulation values, offering natural ventilation independent of the weather as well as efficient solar protection. Radiant floor-slabs and geothermal heating help to further reduce energy consumption.

The KfW Westarkade was awarded “Best Tall Building in the World 2011” by the Council of Tall Buildings and Urban Habitat, Chicago (CTBUH)
