Britain's most energy-efficient home has fuel bills of just £70 a year

A house in Huddersfield is on its way to becoming the most energy-efficient home in Britain. Belonging to Geoff and Kate Tunstall, the green home called "Passivhaus" will merge British construction techniques with German technology. Unlike other conventional energy-saving buildings that use renewable like wind turbines and ground source heat pumps, this one creates a simple "tea cosy" effect.

In order to ensure entire air and wind tightness, Passivhaus incorporates a simple design, careful construction, orientation toward the sun and 15 times greater insulation as compared to the government building regulations requirement. It has a unique mechanical heat recovery ventilation system that is responsible for letting in fresh air from the outside, which is warmed using 99 percent of the heat from the outgoing air.

The three-bedroom property being build and managed by the Green Building Store in Huddersfield uses a German computer software package to measure air tightness and energy efficiency. The Passivhaus is the first to use British construction methods with blockwork, a cavity wall and stone cladding. Being built for a mere £140,000, it will give a 90 percent reduction in fuel bills, which means the couple will have to pay just £70 a year. The Tunstall’s Victorian cottage that will be the first Anglicised version of the famous German Passivhaus will be complete in February next year.
