In the U.S. Department of Energy Solar Decathlon, 20 collegiate teams design and build energy-efficient houses powered exclusively by the sun. These teams spend almost two years creating houses to compete in the 10 contests of the Solar Decathlon. The winning team produces a house that:
- Is affordable, attractive, and easy to live in
- Maintains comfortable and healthy indoor environmental conditions
- Supplies energy to household appliances for cooking, cleaning, and entertainment
- Provides adequate hot water
- Produces as much or more energy than it consumes.
The Solar Decathlon challenges the collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and attractive. The winner of the competition is the team that best blends affordability, consumer appeal, and design excellence with optimal energy production and maximum efficiency.
The first Solar Decathlon was held in 2002; the competition has since occurred biennially in 2005, 2007, and 2009. The next event will take place at the National Mall’s West Potomac Park in Washington, D.C., Sept. 23–Oct. 2, 2011. Open to the public free of charge, visitors can tour the houses, gather ideas to use in their own homes, and learn how energy-saving features can help them save money today.
