'On a cold wee kend this month, thousands of people waited in the rain to visit twenty unusual buildings set up in the heart of Washington, DC. They gathered to see buildings that get all the power they need from the sun. But these structures were not just about solar power.

It brought together teams representing twenty universities from Canada, Germany, Spain and the United States. The main goal was to create beautiful homes that can meaningfully cut energy use.
