While architect Werner Sobek chose the name "active house," a contrast to the passive house philosophy of efficency and conservation, the incredible energy production achieved by the B10 wouldn't be possible without a next-level envelope. Utilizing opaque surfaces and a vacuum-insulated, frameless glass front, the model home achieves a super-tight seal; the terrace even folds up to completely shield the home from sun when residents are gone. "When we started building these research homes in 2000, we were making passive homes, but have always wanted to get around the limits of small windows and lots of insulation and make something active," says Sobek. The home is outfitted with Knoll furniture and kitchen furnishings by Leicht Küchen and Hansgrohe.
