On the inside the QB1 is 3x3x3 meters, about 97 square feet. It was designed to generate at least as much electricity as it uses, making it energy-positive. In fact the designers estimate this house, with its 1.48 kW roof mounted photovoltaic system, would pay the owner £1000 per year in FiT income. FiT is the UK Government’s Feed-In Tariff program, which pays an incentive for producing energy from renewable sources.
I requires a grid connection to feed energy back to the grid and a water source. It needs no sewer connection. Waste is either composted or processed on site in a small reed-bed and soak-away.
This is the first prototype of the QB1 and it’s on display at St Andrew’s Square, Edinburgh, as part of the Edinburgh Science Festival. The Cube Project is the creation of Dr Mike Page.
