Prototype home is a micropower plant

Signal of change / Prototype home is a micropower plant

Aktivhaus B10 produces double the amount of energy it needs, from sustainable sources, with help from self-learning controls that improve its efficiency over time. Rather than aiming to be self-sufficient and to stay off the grid, the house is designed to share its energy. It uses intelligent building automation and energy management systems to communicate with neighbouring buildings and power utilities. A fleet of electric vehicles help to maximise its efficiency, minimise energy costs, and shift peak demand, while surplus power is supplied to the poorly insulated heritage buildings in the local neighbourhood.  

The Aktivhaus B10 is part of a research project exploring how materials, design and technology can extend home sustainability in an increasingly built-up world. The project is being run by E-Lab Projekt, a subsidiary of the Stuttgart Institute of Sustainability that promotes and develops methods and technologies for sustainable building. With a target of 200% net annual energy production, the Aktivhaus B10 represents a promising new approach to the future development and renovation of our built environment.

So what?

After aiming to reduce the emissions of the built environment, the next logical step is to move towards net positive buildings — that is, buildings which can produce surplus energy to help meet the needs of the existing building stock, and thus reducing the need for costly and resource-intensive renovations. Transport has a role to play in such a system, balancing energy demand and supply in 'vehicle-to-grid' networks. In future, we may commonly be encouraged to charge cars and bikes at the workplace during peak solar production hours in the future; bringing some of this energy home to use during peak demand hours in the evening.


What might the implications of this be? What related signals of change have you seen?
