The low energy house built by BM3 Director Ian Foden last year is proving its worth during the first spell of cold weather this winter. The house which features a number of low energy technologies, very high levels of air tightness and excellent insulation values needs a very low level of heat input. Ian said "We are getting good solar gains from the large area of south facing triple glazing in the house, and heat losses are low. We are getting by with minimal heating from the air source heat pump". Annual space heating and hot water bills are expected to be below £400 per year.
