The new version of the footprint as „3-zone-living home“ consists of three different temperatured zones in one compact building envelope. The living and sleeping areas are separated but linkable via a winter garden. All functions of the living space pop-out of the northern walls. The lighting via the inner yard remained but the facade itself became patterned with round photovoltaics. The walls on the east, south and west conscist of translucent insulation and are filled with phase change material (PCM).
