European Solar Decathlon – Solar home creates twice the energy it uses

Our homes were never designed for energy efficiency. So what happens when designers, architects, and engineers approach the problem?

From the European Solar Decathlon:

“The house generates twice as much energy in Hungarian conditions and three times as much in Madrid as the house itself spends,” the Odooproject team states. “This amount is able to serve two other house’s needs, or provide a 70-kilometer (43.5-mile) long travel distance – daily – for an electric car.”

Designs like these bring us closer to taking homes off the electrical grid. And that is something I’ve heard engineers say is the solution, and the where the trend is going.

The central idea is the home is 100% energy-efficient. In winter that means the slightest amount of heat from the sun gets trapped in the house, and can provide the majority of winter heating.
