An 800-square-foot solar-powered house designed by Pittsburgh students took 10th place in the U.S. Department of Energy's second Solar Decathlon, which ended yesterday on the National Mall in Washington, D.C.

A team from the University of Colorado took first place among the 18 teams in the competition. Each team designed and built energy efficient houses with solar-heated water and solar-generated electricity and then transported them to the Mall for judging.

The Pittsburgh entry was developed by students from Carnegie Mellon University, the University of Pittsburgh and the Art Institute of Pittsburgh.

The house will be permanently installed on the Carnegie Mellon campus, where it will become the home of the Steinbrenner Institute for Environmental Education and Research.
