Solar Factory in Freiburg
The solar-cell production plant and a market for eco-products are housed in a low hall to the north; the administration and two dwellings in a four-storey linear tract to the south. The office tract is enclosed on three sides by a solid sandstone wall with 16 cm full thermal insulation. Extending over the entire south face is a glazed hall, which serves as an access and communication space and as a venue for various events. The "solar" facade, sloping at an angle of 17°, is supported at the top by the cantilevered floor slab over the offices.
