Domestic buildings absorb about 1/4 to 1/3 of the UK's primary energy. New houses can be designed which use half, or even considerably less than half of the energy consumed by their contemporaries. Typical examples are the Danish Zero Energy House and the Saskatchewan House. Unfortunately the U.K. building industry and its clients generally ignore long-run costs, in favour of lower initial capital investment. Such a position favours insulation and passive solar techniques, as opposed to more complex methods, for reducing network energy consumption in buildings.
