Aktivhaus B10 is part of a research project examining how innovative materials, structural designs and technologies can improve our built environment in a sustainable manner. Thanks to a sophisticated energy concept and a predictive, self-learning building control system, the house generates twice as much energy from solar power as it requires for its own needs. The surplus energy is used to power two electric cars and – by employing smart grid technology – a neighboring house designed by the architect Le Corbusier (and home to the Weissenhof Museum since 2006).
