solar flair

With an exterior clad entirely in thin-film photovoltaic panels, Team Germany's two-levelsurPLUShome was designed for energy generation, helping the team repeat its 2007 Solar Decathlon victory.

Designed to Passive House standards, the University of Illinois' Gable Home has such a well-insulated and well-sealed envelope that body heat from Decathlon students and visitors was enough to create a comfortably warm interior.

Water conservation was key in Team California's Refract House. A rain pool collects irrigation water in winter and acts as a dry garden in summer.
