Turns out the Rhône Alpes team from France with the Canopea house won Solar Decathlon Europe held in Madrid.  Their home is actually the top of a conceptual “Nanotower” that the team proposed to bring single-family style living back to the urban core.  The top level acts like a rain forest’s canopy — hence the name — by collecting 95% of all solar energy and 30% of rainwater for the tower.  Canopea was built of a prefab CORE, site-built SKIN, and a SHELL capable of off-site fabrication as well.
