The most energy efficient house in the country has been officially unveiled in Christchurch.
Its designer had been aiming for a nine-star energy efficiency rating and this afternoon he was awarded a perfect 10 – the first ever in Australasia.
Most houses in New Zealand only carry a three-star energy efficiency rating – the minimum requirement of the building code.
So for the three-bedroom, two-storey Addington home to achieve a perfect 10, designer Bob Burnett had to think outside the box.
That includes 18 solar panels neatly tucked out of view on the roof, generating ample electricity. It's seriously insulated of course and has in-floor heating and a reclaimed heat ventilation system.
Even the grey water is not wasted.
