Fourteen houses entered in the U.S. Energy Department's 2015 Solar Decathlon have been assembled in Irvine, Calif., and are on public display through Sunday. It's a diverse collection of energy-efficient dwellings designed by collegiate teams from the United States, Germany, Honduras and Panama. The teams and their solar-powered houses are competing in 10 contests to determine an overall winner. Judges award points based on a home's affordability, attractiveness, comfort and net energy consumption. The winner will be announced Saturday.
Can't make it to Irvine this weekend? You can tour the houses online and vote for your favorite. Voting ends Sunday; the "fan favorite" will be announced on Monday.
