Some days ago I was visiting a zero-emissions building in Spain, this building uses some renewables systems to generate both thermal and electric energy like geothermal, solar pv in facades and roofs and three small wind turbines. Moreover the building uses mainly the natural lighting has a very low energy consumption, etc...
The info about the building is in the following link: info
I also work in a Zero-emisions building, the information is available in www.fcirce.es
As the issue of zero-emission buildings is advancing so fast I wonder if you know other proposals for zero-emission buildings, their results and main characteristics.
I hope your comments
