This modest three bedroom house uses batteries to store the electricity which it generates from the solar panels that function as the roof, and has massive amounts of insulation to reduce energy use in winter months, it should be able to export electricity to the national grid for eight months of the year.
“One reason we built this house,” says Cardiff University design team leader Professor Phil Jones, “was to demonstrate to builders that you could meet the standards at an affordable price with off-the-shelf technology. The housebuilders could do it too if they wanted to.” According to Jones, the building costs of the 100 square metre energy positive house could drop below £100,000 if several were built at the same time
