Zero Emissions House : Mill Hill
One-of-a-kind house designed to be heated off-grid, purely by extracting heat from the air and the sun. Energy from photovoltaic cells is stored in a battery. This will power an air source heat pump so that heating and hot water is provided free from the national grid.
The house is also super insulated, and triple-glazed to retain heat as well as using other energy efficient technologies to improve the living environment.
