Team Germany's unique architecture, which featured solar cells integrated into the wood blinds covering their home's windows, won over the jurors and led to a first-place win in the 2007 Solar Decathlon for Technische Universität Darmstadt.

Solar Decathlon 2007


(200 points)

Teams are required to design and build attractive, high-performance houses that integrate solar and energy efficiency technologies seamlessly into home design. Scoring well in Architecture is crucial; teams earn up to 200 points—more points than any other contest. A jury of esteemed architects tour the team homes to judge the Architecture contest. They evaluate three main factors:

  • Firmness—the house's strength, suitability, and appropriateness of materials for the building

  • Commodity—ease of entry into the house and circulation among the public and private zones; architectural strategy used to accommodate the technologies required to run the house; and generosity and sufficiency of space in the house

  • Delight—surprises, unusual use of ordinary materials, or use of extraordinary materials in the house.
