Construction

The roof structure is made up of mutually supporting cantilevers, whose steel hollow core girders function simultaneously as large gutters to drain the immense run-off of tropical rainwater. Given the hot, humid Amazonas climate, the roof continues into the façade to provide shade and shelter for spectator circulation areas and vertical access points. The fields of the roof and façades consist of translucent fiberglass fabric, whose low-emittance coating reflects heat radiation and thus has a cooling effect. The natural ventilation arising in combination with the façade apertures creates a pleasant microclimate.
