A unique structure which roofs the main bus station in the Swiss town of Aarau was built at the end of 2013. The canopy has a cloud-like shape and contains the largest single-chamber cushion in the world. It has a volume of 63,920 ft3 and a roofed area of 11,517 ft2.

Model

Structure

The external dimensions of the roof are l x w = ~ 138 ft x ~ 128 ft. The eave height is 23 ft. There is an organically-shaped opening in the center of the canopy. The air cushion is inflated and reaches a height between 4.3 ft and 10.5 ft. Furthermore, a clear and blue‑dyed foil with a finely balanced print was used.

The cushion is enveloped and spanned by an irregular mesh of stainless steel cables that are fixed to the curved pipes on the edge. The edge beams are supported by a load-bearing system consisting of steel girders lying within the cushion.

The entire technical infrastructure for water, air, electronics, and sensor technology has been integrated into the inner steel structure.

The roof is supported by a total of 11 filigree columns made of round pipes with a diameter of d = 11 3/4 in that are slightly inclined in an axis. The "cloud" seems to float. The ETFE cushion has such an airtight and energy‑saving design that only 15% of the forecast air power needed to sustain the structure is required.

Immediately after the bus station was put into service, it became an exhibit in the "architektur 0.13" Swiss architectural trade show in Zürich.
