My unit is based on the underlying hypothesis that fossil fuel use will become incredibly restricted in the future, primarily as a result of climate change. Significant steps are being taken to reduce building energy use within the western world, but so far the methods employed require the expenditure of large amounts of fossil fuel in order to achieve reduction in operating costs, principally by the compulsory of very high levels of insulation abd effective draught proofing.
