“折叠式”多孔、通透的铝制外立面——一座地标性的综合体

来源：搜建筑（ID：sjz9999）

位于尼日利亚拉各斯Ikoyi的Kingsway Tower是一座地标性的综合体建筑，位于Alfred Rewane路的一个显著角落，这条干道将城市一分为二，北至机场，南至维多利亚岛。

由南非建筑师SAOTA设计，Kingsway Tower高15层。它有一个地下室，一个两层的零售裙楼，一个停车裙楼和12层的办公楼层。

金斯威大厦的设计不仅为拉各斯--尼日利亚的经济中心和世界上发展最快的城市之一--引入了新的建筑理念， 而且在质量和执行上也毫不逊色，体现了这个新兴市场在全球范围内的重要性。

Kingsway Tower in Ikoyi, Lagos, Nigeria is a landmark mixed-use building set on a prominent corner on Alfred Rewane Road, an arterial road that bisects the city leading north towards the airport and south to the Victoria Island. Designed by South African architects SAOTA, Kingsway Tower is 15 storeys high. It has a basement, a two-level retail podium, a parking podium and 12 office floor levels. Not only does the design of Kingsway Tower introduce new architectural ideas to Lagos – the economic centre of Nigeria and one of the fastest growing cities in the world – but it is also uncompromisingly world-class in its quality and execution, reflecting the importance of this emerging market in a global context.

阿尔弗雷德-雷瓦内路及其周边地区位于著名的住宅区Ikoyi，已被重新划定为混合用途走廊，致使办公和酒店开发的开始繁荣。

然而，拉各斯的许多开发项目都具有相当的匿名性，一般都遵循标准的商业模式，采用混凝土板和幕墙外墙。

"我们希望设计出一栋直接参照拉各斯这一事实的建筑，其外立面能响应当地的气候条件，"该项目的首席建筑师SAOTA总监Greg Truen说。

Located in Ikoyi, a prestigious residential neighborhood, Alfred Rewane Road and its surrounds have been rezoned to create a mixed-use corridor, resulting in a boom in office and hotel developments. Much of the development in Lagos, however, has a fairly anonymous character, generally following a standard commercial model with concrete slab and curtain wall facades. “We wanted to design a building that made direct references to the fact that it was in Lagos, with a fa?ade that responded to the local climatic conditions,” says SAOTA Director Greg Truen, lead architect on the project.

塔楼独特的膨胀、飘扬的形式巧妙地参考了拉各斯泻湖上传统船只的方帆，同时传达了城市气候条件中特有的微风效果。

塔楼升起在一个波浪形的天幕之上，天幕底部有 "编织 "的图案，让人联想到微风中的织物。天篷围绕着一个两层的零售裙楼，在街道上提供遮挡，并在最突出的角落向入口处抬起，令人心动。

The distinctively swollen, billowing form of the tower subtly references the square sails of the traditional boats on Lagos Lagoon while conveying the effect of the gentle breeze that characterizes the climatic conditions of the city. The tower rises above a wavy canopy with a “woven” pattern on its underside, reminiscent of fabric caught in the breeze. The canopy sweeps around a two-level retail podium, providing shelter at street level and lifting invitingly towards the entrance at the most prominent corner.

塔楼外立面上的折叠式穿孔铝制屏风主要负责建筑的标志性标识。

然而，SAOTA小心翼翼地避免直接或文字上的隐喻等同。他们更倾向于抽象其图案的灵感--热带植被，特别是棕榈树，沿着城市内和周围的热带泻湖--使它们看起来只是 "他们的地方"，在美学、实用性和性能上适合气候和经济，而不是宣称公开的文化参考。

外立面的屏风是多层排列的，创造了一个多孔、通透的立面，具有深度和雕塑感， 正如Truen所说，"当各层之间相互转换时，内部投下了有趣的阴影"。

The folded, perforated aluminum screens on the tower’s outer fa?ade are primarily responsible for the building’s iconic identity. SAOTA was, however, careful to avoid direct or literal metaphorical equivalencies. They preferred to abstract the inspiration for its patterning – tropical vegetation, especially palm trees, along the tropical lagoons in and around the city – so that they seem simply “of their place”, appropriate to the climate and economy in their aesthetics, practicalities and performance rather than asserting overt cultural references. The screens on the outer fa?ade are arranged in multiple layers, creating a porous, permeable fa?ade with depth and a sculptural quality, that, as Truen puts it, casts “interesting shadows internally as the layers shift against each other”.

与典型的欧美现代主义传统塔楼不同，立面处理的配置更像是店面而非幕墙。"板块从玻璃面投射过去，"Truen说。

铝制屏风位于板块的末端，这不仅可以通过减少太阳能负荷来提高建筑的被动性能，还可以让周边有通道，便于清洁和维护。

"另一个气候对策是将建筑定位为短立面朝向东西，长立面朝向南北，"Truen说。"在拉各斯，太阳很快就会进入天空，所以你要处理的是来自相当垂直角度的热负荷。悬挑、遮阳装置和南北立面的组合非常有效。"

Unlike typical European and American towers in the modernist tradition, the fa?ade treatment is configured more like a shopfront than a curtain wall. “The slab projects past the glass face,” says Truen. The aluminium screen is positioned at the end of the slab, which not only improves the passive performance of the building by reducing the solar load, but it also allows access around the perimeter for easy cleaning and maintenance. “The other climatic response was to position the building with the short facades facing east-west, and the long facades north and south,” says Truen. “The sun gets into the sky very quickly in Lagos, so you’re dealing with a heat load that is coming from a fairly vertical angle. The combination of the overhangs, the shading devices and the north-south elevations is very effective.”

弧形顶棚下的街道立面布满了公众可进入的空间，使其与环境紧密相连，并呈现出与街道和人行道高度开放的视觉联系，特别是在Glover和Alfred Rewane路的显著拐角处。

在夜间，LED照明增强了开放性和无障碍的印象，更不用说它的视觉效果了。 "激活街角并赋予它存在感很重要，"Truen说。

这种方法在拉各斯是不寻常的，在那里，大多数建筑都向街道呈现出空白的墙壁和围栏，将它们与周围的环境割裂开来，几乎没有做任何事情来提高周围街景和共享公共空间的质量。

SAOTA希望这种干预措施能够促进积极的变化，同时为周围的城市结构做出贡献。

The street level facade below the curved canopy is populated with publicly accessible spaces, tying it meaningfully to its context and presenting a highly open visual connection to the street and sidewalk, particularly on the prominent corner of Glover and Alfred Rewane Roads. At night, LED lighting enhances the impression of openness and accessibility, not to mention its visual impact. “It was important to activate the street corner and give it a presence,” says Truen. This approach is unusual in Lagos, where most buildings present blank walls and fences to the street, severing them from their surroundings and doing little or nothing to enhance the quality of the streetscape and shared public space around them. SAOTA hopes that this intervention will catalyze positive change while making a contribution to the urban fabric immediately around it.

大堂的内部建筑和设计采用了天幕的对角线网格状元素，在镶板中表现为围绕对角线轴线折叠的多面木材三角元素。

这种雕塑的方法和简单的图案，以及使用现成的材料，使得所有的细木工板都是在当地采购和建造的。

接待处上方的锥形顶棚，从建筑之外的角度看，具有冲击力，从外面的街道上就能看到。和外立面一样，室内大堂的处理也在你走近它时演绎出更多的细节和趣味。

The interior architecture and design of the lobby picks up on the diagonal grid-like element of the canopy, expressed in the paneling as faceted timber triangular elements folded around a diagonal axis. This sculptural approach and simple patterning, along with the use of readily available materials, allowed for all of the joinery to be sourced and built locally. The bold cone-shaped canopy over the reception desk has an impact from beyond the building, creating interest from the street outside. Like the fade, the interior lobby treatment renders more detail and interest as you approach it.

拉各斯的电力供应不稳定，水和污水处理等市政服务有限，甚至没有。因此，除了被动式能源解决方案大大降低了对空调的需求，并提供充足的自然采光外，所有的服务--供水和处理、备用发电和污水处理--都在现场提供。

拉各斯的快速发展，人口高达2000万，并且还在不断攀升，这对城市及其建筑提出了独特的要求。"这是一个没有任何时间怀旧的地方，"特鲁恩说。"它在不断地更新自己，以应对所需的容量。"

The power supply in Lagos is erratic and municipal services such as water and sewage are limited or absent. As a result, in addition to passive energy solutions that significantly reduce the requirement for air-conditioning and providing ample natural lighting, all servicing – water supply and treatment, backup power generation and sewage treatment – is provided on site. The rapid growth of Lagos, with a population upward of 20-million people and climbing, places unique demands on the city and its architecture. “It’s a place that doesn’t have any time for nostalgia,” says Truen. “It’s constantly renewing itself to cope with the capacity that’s required.”

在此背景下，金斯威大厦旨在开创一种新的设计理念，解决城市的独特需求和挑战，同时反映当地和全球的信心，金斯威大厦的第一个租户--国际计算机软件和技术公司微软也肯定了这种做法。

In this context, Kingsway Tower aims to inaugurate a new design narrative, addressing the city’s unique demands and challenges while reflecting both local and global confidence, an approach affirmed by Kingsway Towers’ first tenant, international computer software and technology company Microsoft.
