架构师提供的文本描述。最近，瑞士的首府奥罗市(Arau)获得了自己的云层，形成了一个有机形成的公交车站天篷，表面反光且半透明。可以说，屋顶在火车站前院上方盘旋。然而，不像它的气象同名，这云提供保护免受雨和雪。

Text description provided by the architects. Recently, the Swiss city of Aarau, a cantonal capital, has gained its own cloud in the shape of an organically formed bus station canopy with a reflective and semi-translucent skin. The roof hovers, so to speak, above the forecourt of the railway station. However, unlike its meteorological namesake, this cloud provides protection from the rain and snow.

作为西奥·霍兹在奥罗新建火车站的一部分，车站前院和汽车站得到了新的面貌。现有的固定装置已被拆除，地下停车场也已搬迁，以便巴士站现在都能容纳在Bahnhofplatz内。Mateja Vehovar和Stefan Jauslin设计了一个像羽毛一样轻的公共汽车站天篷，想在繁忙的Bahnhofstrass和新火车站之间创造一个平静的避风港。这为往返于瑞士联邦铁路和奥罗地区公共汽车之间的通勤者创造了一个欢迎区，也为夜猫子提供了一个聚集地，散发着都市气息。

As part of the construction of Theo Hotz's new railway station in Aarau, the station forecourt and bus station have been given a new face. Existing fixtures have been removed and the underground car park relocated so that the bus stops can now all be accommodated within Bahnhofplatz. Mateja Vehovar and Stefan Jauslin have designed a bus station canopy which looks as light as a feather, with the idea of creating a haven of calm between the busy Bahnhofstrasse and the new railway station. This has created a welcoming zone for commuters transferring between the Swiss Federal Railways and Aarau's regional buses, and a hangout for night owls which radiates metropolitan flair.

 Structural Plan

在空气缓冲膜的中心是一个有机的开口。半透明的表面和露天的对比增强了光的感觉和在户外的感觉，但本质上不受元素的影响。这一印象受到了一系列战略决定的鼓舞：使用透明和蓝色的透明膜(斯特凡·乔斯林和保罗·摩纳哥的作品)，使用透明和蓝色的薄膜(斯特凡·乔斯林与保罗·摩纳哥合著)，支架向一个轴轻微倾斜，消失在靠垫中，并携带“云”，膜与内部支撑结构之间的不同距离，一项将水、空气、电气和传感器技术完全集成到钢结构中的技术基础设施，以及衬垫下面不规则的不锈钢电缆网络，其设计目的是给膜提供所需的跨度。这些多个无定形膜海湾破坏了整体形状。它们在薄膜皮肤上提供无数的反射和光的播放，这些光是由排列在支架上的线性灯具触发的。内部支护结构隐约可见。斜视下，支架逐渐消失在背景中，树冠的体积也随之增大。

At the centre of the air-cushioned membrane canopy is an organically shaped opening. The contrast between the semi-transparent surface and the open air intensifies the impression of lightness and the feeling of being out in the open, yet essentially protected from the elements. This impression has been encouraged by a series of strategic decisions: the use of a translucent membrane, both clear and blue-dyed, with a finely balanced print (by Stefan Jauslin with Paolo Monaco), the supports with their slight slant towards one axis which disappear into the cushion and carry the "cloud", the varying distances between the membranes and the support structure inside, a technical infrastructure fully integrated into the steel construction carrying water, air, electrical and sensor technology, as well as the irregular network of stainless steel cables below the cushion which is designed to give the membrane the required span. These multiple amorphous membrane bays break up the overall shape. They provide the numerous reflections and plays of light on the membrane skin, triggered by the linear luminaires arranged in line with the supports. The internal supporting structure is faintly discernible. Viewed obliquely, the supports fade into the background and the canopy gains volume.

无论云的外观多么轻巧和简单，它的设计都需要一支熟练的规划师团队，他们善于沟通，并与所有参与方密切协调。因此，建筑师Vehova

Regardless of how light and simple the cloud appears, its design necessitated a skilled team of planners good at communicating, and close coordination of all the parties involved. For this reason, the architects Vehovar & Jauslin Architektur brought in formTL at an early stage as a specialist to deal with the support structure and membrane skin. formTL had a particular interest in ensuring that the design provided by Vehovar & Jauslin Architektur AG would be feasible, and in bringing out its lightness and filigree nature. This was achieved by basing the planning and realisation on three factors: the planning team directed by suisseplan consistently pursued the aim of building the most airtight cushion with the most economical form of operation. The consortium entrusted with the membrane cushion now consisted of committed specialist firms. Moreover, formTL was given full control of the structural planning, integration with the building services engineers, invitation to tender, management of specialist construction work and quality control.

通过将三部分上膜和下膜分别固定在弯曲的外管上，可以实现云的简单和结构清洁细节。有1070平方米的覆盖面积和1810米的体积，巴士站的屋顶是世界上最大的单室膜气垫。道路下有四根120米长的聚乙烯管，通过再循环、清洁、干燥的空气供应气垫，另有四根管子将空气带回空气控制单元。根据天气情况，整个系统包括支撑空气系统、油管和膜垫，由高于外部气压300至850帕斯卡的传感器维持。由于只有在2140平方米的垫层表面扩散的湿气，而且垫层和油管或多或少都是密闭的，所以屋顶的操作非常经济。

By fastening the three-part upper and lower membranes to the curved outside tubing separately, it was possible to achieve the simple and structurally clean detailing of the cloud. With 1070 m² of covered area and a volume of 1810 m³, the roof of the bus station is the world's largest single-chamber membrane air cushion. Four 120-metre long polyethylene tubes under the road supply the pneumatic air cushion with recirculated clean, dry air, and another four tubes take the air back to the air control unit. Depending on the weather, the entire system comprising support air system, tubing and membrane cushion is maintained by sensors at 300 - 850 pascals above the outside air pressure. As only the moisture has to be removed that is diffused over the 2140 m² cushion surface, and both the cushion and the tubing are more or less airtight, the roof is highly economical to operate.

巴士站檐篷在启用后，随即在苏黎世举行的“Architektur 0.13”展览上展出。2014年4月26日至7月27日期间，在德国安伯格空气博物馆举办的题为“Bauen MIT Luft”(有空气的建筑)的展览上可以看到公交车站的屋顶。

Immediately after it was commissioned, the bus station canopy was included as an exhibit at the "architektur 0.13" exhibition held in Zurich. Between 26 April and 27 July 2014 the bus station roof can be seen at the exhibition entitled "Bauen mit Luft” (Building with Air) to be held in conjunction with a 10-year retrospective of formTL at the Air Museum in Amberg, Germany.
