The building is certified as a passive house – i.e. it requires a minimum of energy despite the extreme conditions. This was achieved through the use of modern technology to control the building’s ventilation a heat pump and smart home automation. Nevertheless one important precondition was the building’s simple and rational form – a typical trait for the architectural designs of Stempel & Tesa?. Thanks to its heat gain the ideally oriented large-format glass offer an advantage in winter and belie the preconceived notion that passive houses cannot have large windows.
