A terraced house built just after the First World War cutting its energy consumption by nearly two-thirds after being fitted with a range of state-of-the-art economy measures by university researchers.
The 'Energy House' created by the teams from Salford and Leeds Metropolitan Universities was intended to prove that the materials and technology were available to retro-fit older homes, and substantially cut energy costs, lower carbon dioxide emissions, and halve its level of air loss.
In addition to bringing loft insulation and glazing in the house up to the highest modern standards, extra insulation was fitted to internal and external walls.
Saint-Gobain, the building materials products involved in the project, said it had proved that, by installing high-quality materials throughout, the time taken to recoup the cost of the works could be significantly reduced.
"This research has direct impact on those vulnerable families currently living in fuel poverty,” said Richard Fitton, Salford University's technical manager of the test house.
Professor Chris Gorse of Leeds Metropolitan University added: “The results are impressive, considering that the baseline building had double-glazing and roof insulation and would not be considered a poor example of this type of dwelling.”
