Ryan Abendroth is the founder, principle, and practitioner of Passive Energy Designs in St. Louis, Missouri—a company that consults on high-performing, low-energy buildings. To date, he has consulted on more than 100 buildings to help others design and achieve ultra-efficient houses that are aesthetically pleasing and functionally livable. He credits this career to his participation in the U.S. Department of Energy Solar Decathlon 2009, an event that he calls "transformative" to his life.

David Schieren is the chief executive officer of a leading Long Island, New York, solar engineering and installation company. He’s also a U.S. Department of Energy Solar Decathlon alumnus and outspoken advocate for the competition.

Congratulations to Team Rhome from Universitá Degli Studi di Roma TRE, the winner of Solar Decathlon Europe 2014! The team’s Rhome for Dencity house received first place overall in the final award ceremony of the competition Saturday evening in Versailles, France.

A brand new city sprang up—almost overnight—about 15 miles southwest of Paris. You won’t find a cookie-cutter template for design here, as each house is unique in function, form, and style. The one thing all of the houses have in common is they are designed, built, and tested to operate on pure, green, and clean solar energy.
