The Efficiency House Plus with Electromobility represents the prototype smart building developed within the framework of the new energy-efficient construction program presented by the German Federal Ministry of Transport, Building and Urban Development. The newly created program intends to test the latest construction and energy components on buildings in real-world conditions, and thus prepare recommendations for their on-going development and to further improve their economic viability. The high-tech prototype Efficiency House Plus with Electromobility is a compact and glazed two-storey house based on the newest energy standards, which generates its own energy for user consumption and vehicle charging.  Based on “smart” housing principles by using the latest and efficient energy and material features, the Efficiency House Plus with Electromobility demonstrates the feasibility of synergies between “smart” housing and the use of electric vehicles.
