The new triple sports centre was officially opened on the ETH campus at Honggerberg in May 2009. This attractive and spacious sports complex, with its versatile range of potential uses was designed and built by the architectural team Dietrich Untertrifaller. The low-rise building is ideally embedded in the landscape, and one of its major characteristics is the exemplary sustainability of its energy balance. This architectural monograph documents the previous building designed by A.H. Steiner, as well as the planning, execution and usage of the new complex.
