The Artisans Group has built a home in the United States that is extremely energy efficient, to the point where in the winter the interior will stay warm with almost no energy needed. In fact, it will take "less energy than it takes to run a hair dryer," according to DesignBoom.
This feat is achieved through a few different techniques, but the main one involves utmost attention to insulation throughout. Since most of the house is air-tight allowing the warm air to stay trapped inside, only minimal heating is needed for a short period of time.
The home was built for a smaller family, who clearly are doing their best to reduce their impact on the environment through living in this abode.
