The 2007 Solar Decathlon took place on the National Mall in Washington, D.C., October 12 to 20. This competition enlisted 20 teams of college and university students to design, build, and operate the most attractive, effective, and energyefficient solar-powered houses. Each house was instrumented with sensors to evaluate how well the students met the challenge. Campbell Scientific dataloggers were chosen for a key role in the evaluation phase.
Over the previous two years before the event, each team of college students designed a solar house, knowing from the outset that it must be powered entirely by the sun. The competition demanded that their designs maintain the house within a certain temperature range, provide lighting, run appliances, charge an electric car, and much more. They then built their solar houses, learning as they went.
The 20 teams transported their buildings to Washington and assembled them on the National Mall. The judging then began, with Campbell sensors and dataloggers measuring factors such as light, temperature, and humidity. Our gear helped the judges gauge performance in contests of engineering, comfort, appliances, hot water, and lighting.
The U.S. Department of Energy holds the Solar Decathlon every two years to serve three main purposes:
There are many simple ways to save energy, and many relatively simple ways to generate energy from the sun. Solar energy technologies are clean, producing significantly less pollution than other options. And we can count on that energy source as long as the sun shines. Campbell Scientific was proud to provide tools to help measure our progress in energy production and use. For information, photos, and videos about this competition, visit solardecathlon.org
