Share this Post:
The German federal ministry for transport, building and urban affairs has installed an exhibition pavillion in form of a plus energy house in Berlin. The building participated in the solar decathlon competition in Washington DC in 2007 and won the first price. It was designed by the Technical University of Darmstadt and includes energy efficiency technologies for both demand and supply side. The building can be visited in Berlin from middle of May to end of September 2009 and will afterwards be presented in different major cities in Germany.
The used energy efficiency technologies include new insulation materials, high efficient windows and phase change material as well as efficient energy supply technologies like a micro combined heat and power unit, fuel cells, heat pump and photovoltaic panels. The building is a transportable, fully functional light-weight construction and produces more energy than it consumes. A so-called intelligent energy reader indicates possible electrical energy savings. The building is made of sustainable, natural and recycable materials.
