THIS IS — no-doubt — one of the most efficient houses on Earth.

It was designed to be 100% zero emission, and incorporates a ridiculous number of clever tricks and gadgets to truly make it a friend to the environment.

Norway’s Research Centre on Zero Emission Buildings and renowned international architecture firm Snøhetta teamed up to make it possible.

Take a look inside…

The house uses various natural sources to provide all the energy it needs — plus at least enough to power an electric family car for a year. It produces 23,200kWh of energy a year, but through clever and eco-friendly design uses only 7,272kWh…

1,614 square feet of solar panels cover the roof, bringing in an estimated 19,200kWh of energy. The roof is also tilted 19 degrees southeast toward the sun, to maximize sun exposure, as well as make it easier to collect and use rainwater. Thermal solar panels heat the water for use in the house…
