Solar Decathlon – Design, Energy Efficiency, Inspiration

by Deborah Harter Williams

In October, the U.S. Department of Energy sponsored its fifth Solar Decathlon. This year’s competition featured 19 colleges from five countries and four continents. The challenge: design, build and operate the most cost effective, energy efficient and attractive solar powered house. Ten contests over ten days pushed the teams to demonstrate each house's performance, livability and affordability.
