Sonnenschiff (or ‘the solar ship’) started out as a mixed commercial/residential building designed by Rolf Disch and built in 2004, according to Wikipedia “Sonnenschiff”
Since then, other residential buildings have been added, making a whole little community that is energy independent, but not only. It produces energy from solar panels on the south-facing roofs and it saves so much energy by smart design and rigorous building standards that much of the electricity is left over and can be sold to the utility.
According to Inhabitat, the solar city Produces 4X the Energy it Consumes
This has been active and working for some years now, so the question comes to mind: Why has this system not been more widely adopted and copied around the world?
The article is completely misleading. The homes probably produce more energy than the tenants consume, but only if the tenants do not consume a lot of electricity. They do not nearly come close to producing four times as much energy. Greetings from someone who gives tours of the neighborhood, ciao
