Rice's Zerow House
While some student teams tried to invent new techniques for the Solar Decathlon competition, other teams focused more on practicality. Here is Rice University's Zerow House, a house built for $140,000 and which will be installed back home in Houston after the competition. By cutting back on the amount of solar panels used, the home could be built for as little as $80,000.
