With the aim to design an energy efficient house plan, the team went down to the drawing board and came up with this ongoing architectural project: two-story cube-shaped houses, with roofs clad facade and solar cells will generate 200 percent of home energy. This solar house design is not a typical German house. In addition, this solar-powered house combines smart features like hide-away furniture and equipment, or those with some using to make the best of the resources available. Created by students from Technische Universitat Darmstadt in Germany, this striking solar house has been collecting them the top prize in Solar Decathlon competition. Eco house design is also very isolated and equipped with automatic-curtains lourve to reduce unwanted heat gain.
