1st prize in the international "Solar Decathlon 2007" competition to find the most attractive and energy-efficient solar home in 2007 went to Germany. The competition rules require a fully energy-independent building with a floor area limited to 75 m². The prototype is laden with new technologies and concepts: Vacuum insulation (VIP), thermo-active building systems using phase change materials (PCM), solar power generation (PV) integrated into the facade and roof and many other features ensure energy autonomy.
