架构师提供的文本描述。在科隆历史悠久的莱茵那哈芬海港区的第10号地块上，拟建的写字楼位于两个15层高的“吊车楼”办公楼之间，是一个主要的滨水区。该建筑物独特的台阶立面设计，以创造一个强有力的雕塑存在，同时回应海港的意见。此外，所有厂房都安置在建筑物的上层，使屋顶自由成为第五高度，直接被相邻的塔楼所忽略。

Text description provided by the architects. The proposed office building on Plot 10 in Cologne’s historic Rheinauhafen harbour district occupies a prime waterfront position, situated between two fifteen-storey ‘crane house’ office towers. The building’s distinctive stepped elevation is designed to create a strongly sculptural presence while responding to the views across the harbour. In addition, all plant is accommodated within the building’s upper floor, freeing up the rooftop to become a fifth elevation which is directly overlooked by the adjacent towers.

该建筑的节能面板正面的特点是分层效应，特点是浅色阳极铝框架在每个面板的外部和深色，不透明的填充到后面。这种层次分明的构图在提升建筑整体垂直性的同时，也给高地带来了耐人寻味的深度。示范性的可持续服务战略优化了被动建筑要素的使用，同时尽量减少了对技术的使用。这种方法将简单性和最高效率结合起来，在一座建筑物中产生，可使一次能源消耗的Enev法定要求节省45%，从而产生了一个既具有经济可行性又具有创新性的方案。

The building’s energy-efficient panelised facade is characterised by a layered effect, featuring light-coloured anodised aluminium frames on the outer face of each panel and dark-coloured, opaque infills to the rear. This layered composition introduces an intriguing depth to the elevations while enhancing the verticality of the building overall. An exemplary sustainable services strategy optimises the use of passive building elements in conjunction with a minimal use of technology. This approach, combining simplicity with the utmost efficiency, has produced in a building which offers a 45% saving on the EnEV statutory requirement for primary energy consumption, resulting in a scheme which is as innovative as it is economically viable.
