JustK Eco House by AMUNT
Via @yatzer, a zero-energy house in Tübingen, Germany. "The south facing façade is glazed for maximum solar gain with open-work shading panels acting as traditional shutters. The entrance is situated on the same level as the courtyard serving as cold air sluice between exterior and interior while part of the floor slab has been elevated so that an infiltration ditch together with a 75m ground-air heat exchanger could be installed."
