The BSRIA (Building Services Research and Innovation Association) has applauded a four-bedroomed house in West Kirby, Wirral, that costs just £15 a year to run.
The house, built by the owner Colin Usher and valued at £240,000, has cladding and thick insulation on top and all around that traps heat and recycles it via a ventilation system, while under floor heating keeps the bathroom and downstairs floors comfortable.
A unit, which captures warmth from the air outside, generates the heat, and solar panels generate additional power and cash as excess electricity is sold back to the grid.
Jo Harris, head of sustainable construction group, commented: “We understand that the owner pays virtually nothing for his power. This is clearly a great example of energy efficiency at its best that should be used as a shining example within the industry, and BSRIA fully admires this low cost and low carbon approach.
“Indeed, the house uses technology that could help us all achieve a lower carbon and lower cost future. Evidently, there are lessons to be learned for the construction industry here. This property works as an interesting and useful case study and projects like this give us hope that we can achieve low energy buildings.”
