The mixed-use complex 'The Circle' at Zurich airport, hosting a range of activities and services under one roof, is the biggest construction project in Switzerland covering 180,000 sqm (1.9 million sq ft) of usable space. The building’s acoustic windows and sustainable closed cavity façade allow to create a city without noise which follows the ring shape of the motorway and covers parts of the road. Squares and lanes aiming to echo the flair of the city center of Zurich are covered by an air permeable glass roof thus generating rain protected outdoor ambiences. Within walking distance to the terminals, a new architecturally striking building complex is being developed allowing for a variety of uses, services, and interactions and creating the atmosphere of an international trading center. Despite the high compactness, Riken Yamamoto, architect of the new building complex, is grouping the buildings in a way as to reduce large building areas gradually towards the hill which gives the impression of a small scale city center. The single buildings are 9 to 11 stories high and the maximum building height amounts to 38 m (124.7 ft). The development aims to obtain LEED Platinum® sustainability label as well as Minergie certification.
23,000 sqm (247,600 sq ft) ring façade, size 2,700 x 5,500 mm (106 16/94 x 216 17/32”); 52,200 sqm (561,900 sq ft) hill façade, size 2,700 x 5,600 mm (106 16/94 x 220 15/32”); 8,700 sqm (93,700 sq ft) courtyard façade.
For 'The Circle', Gartner manufactured closed cavity façades for a total area of 83,900 sqm (903,100 sq ft) which offer a high degree of energy efficiency, low cleaning expenses and a long service life. Dimensions of the façade units for the 23,000 sqm (247,600 sq ft) ring façade are 2,700 x 5,500 mm with a weight of 1,660 kg (3,660 lb) and for the 52,200 sqm (561,900 sq ft) hill façade 2,700 x 5,600 mm with a weight of 1,450 kg (3,200 lb). The ring façade is sloping over the motorway with the attica covering the road by around 15 m (49 ft) at their maximum inclination to the outside.
