This year’s Solar Decathlon is just hours away- the festivities start TOMORROW in Washington DC with 20 college teams from around the globe competing to design, build, and operate the coolest, greenest energy-efficient, fully solar-powered house! Sponsored by the U.S. Department of Energy, the Solar Decathlon is open to the public October 12th-20th at Washington’s National Mall. Come on down to find out whose design get their shining day in the sun as reigning solar champ! We’ll be there this weekend to report all the news.

The 20 college teams, ranging from the MIT to Germany’s Technische Universität Darmstadt, will build their prototypes and transport them to the National Mall in Washington this October. Together, they will create a solar village, which will be open to the public for perusal. Using the newest products and technologies on the market, the students push the boundaries of residential solar viability, all in the context of a collaborative design process. We covered the Solar Decathlon back in 2005, and the results were very impressive. Check out 2005’s winning designs from the University of Colorado and Cornell below.

What are the demands of the contest? The houses must be able to provide enough energy to power proper lighting, run appliances and even to charge the Gemcar, an electric car made by Global Electric Motorcars. To generate the power, the teams are allowed to use photovoltaic systems, solar thermal systems, and solar hot water systems. The teams are allowed to use their own initiatives as long as the energy source comes from the sun. Because the energy available through the PVs is limited, teams will have to install energy efficient appliances and create an efficient lighting design. The houses will also need proper insulation in order to maintain a stable temperature and reduce the need for heating and cooling.

While technology is an important part of the competition, good solid design is what helps the most. In a house where every kilowatt counts, proper orientation and daylight access becomes invaluable. “One of the guiding principles is that we would be using daylighting and natural ventilation as much as possible,” said Corey Fucetola, MIT’s team leader.

The event takes place on the National Mall in Washington, D.C., October 12 – 20. The team houses are open for touring everyday, except Wednesday, October 17, when they will close for competition purposes. An overall winner is announced on Friday, October 19 at 2 p.m. See the schedule for more information here.

Good luck to all involved from Inhabitat- we look forward to see if anyone will be able to take the crown from the University of Colorado team, who has managed to win the last two decathlons.
