Inspired by the technology behind electric cars, a team from Frey Architekten, the Fraunhofer Institute for Solar Energy Systems (ISE) and Siemens have come up with the design for a brilliant battery-operated residential building. Dubbed as the Smart Green Tower, the structure, along with its spectacular sky garden, will run entirely on solar power.
To be constructed in the German city of Freiburg im Breisgau, the 16-story building will be powered by photovoltaic panels. Integrated along the structure’s facade, the PV array will be capable of harvesting sun’s energy even during low light conditions. The tower will also be equipped with a 0.5 MWh lithium-ion battery, and a set of vanadium redox flow (VRB) batteries that will in turn connect it with the conventional electrical grid.
Unlike similar systems that feature alternating current (or AC) transmission and distribution, the Smart Green Tower will rely on direct current (DC) that will be later converted in the battery before being distributed to the different apartments in the building. According to the developers, any extra energy will be used to power residences and other buildings in the immediate neighborhood.
