Dream Home for 2015?
They call it the Net-Zero Energy home. It has ground source heat pumps (promising a 30% reduction in energy use), photovoltaic arrays, supplementary wind power, high efficiency appliances and battery storage, all talking to each other through a Home Energy Manager.
The folks at treehugger.com are a bit skeptical about the need for all the high tech "gizmos" in such designs, pointing out that " the net-zero energy house will cost 10% more than a conventional house. That's a lot of money; if people would pay that much for extra insulation and better windows they would probably save 30% of their energy costs without fancy heat pumps."
