University teams from around the world are busy constructing sustainable houses at this year's U.S. Department of Energy's Solar Decathlon competition. 20 teams were selected to come to the National Mall in Washington D.C. to compete against one another in designing, building, and operating the best solar-powered, energy-efficient house. The houses are judged based on 10 competitions, which range in point value, from architecture to lighting design to comfort zone. Check out the houses we've featured and vote for which one you want to call home!
