EC*-Cocoon house

Designed by Cyril-Emmanuel Issanchou for the competition Betwin, these low energy houses are prefabricated modules that are installed upon a set of walls and plinths made from locally gathered stones.
The EC*-Cocoons are constructed with timber beams in a double geodesic manner, creating a rigid long-span structure. This form minimizes the exterior surface area and, thus, the heat loss.  The design incorporates several eco-friendly features such as solar panels to warm water and provide heating, off-site wind turbines for electricity, and a heat exchanger on the rooftop which freshens air quality.  The roof allows light to illuminate the center of the home and allows summer ventilation.
