The Aktivhaus B10 is a unique building with about 90 m2 which produces twice as much energy regarding its consumption needs, with the ability to feed two electric vehicles and two electric bicycles. The program was developed by the Stuttgart Institute of Sustainability Stiftung. The House produces energy through a system installed on the roof which combines photovoltaic plates and thermal solar technologies, generating electricity and heat at the same time. In total, the House should generate about 8,300 kWh per year and employ 4,200 kWh per year. The excess energy is supplied to the neighbor’s house or to the network.

The power consumption is reduced to a minimum by high thermal performance of the building. It heats and cools using a heat pump, with an array of ice and a solar storage tank as a source of heat. The only other energy used for heating and cooling is generated from photovoltaic array that is used to power the pump.

The control of the power system automation device, can be controlled through smartphones or tablets, and also includes the automatic coverage of windows by insulating panels to avoid any waste of energy during the night.

This automation system connected to the internet is controlled by using a mobile application, which connects via Wi-Fi when you are inside the House, or by mobile phone signal, if they are away from home, while also allowing the building to prepare for when the occupants to return. The positions of the electric cars are tracked by GPS, so that the heat can be turned on when necessary. It is also possible that the lighting is switched on or off and the blinds rise or lower.

Among its functions, the power management system, adapts with the routines of its users to ensure the building is properly powered and electric cars properly loaded when needed, while ensuring that the overall usage is minimized, even when the occupants of the House are not present during the day, putting the systems in power-saving mode.

The Aktivhaus B10 has a simple rectangular format with a ground floor, but more floors can be added, making possible for the creation of multi-family residential buildings with features self-supporting. The facade follows horizontal lines and is covered by semi translucent glass on the front, optimizing the use of natural light and ventilation.

At this early stage of the project, the residence will be completely dismantled and rebuilt elsewhere. In a second phase of the project, it is foreseen that two students live in one of these homes to test the performance of real-time systems.
