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.

On Aug. 28, U.S. Senate Majority Leader Harry Reid visited DesertSol—the University of Nevada Las Vegas (UNLV) house that won second place overall in the U.S. Department of Energy Solar Decathlon 2013. Now located permanently at the Springs Preserve in central Las Vegas, Nevada, DesertSol has been one of the Preserve’s most popular attractions since it opened to the public in March 2014.

Matthew O’Kelly lives the benefits of his U.S. Department of Energy Solar Decathlon experience.

O’Kelly participated twice in the Solar Decathlon—first as the HVAC engineer for The Ohio State University (OSU) 2009 team and then as the project engineer for the OSU 2011 team. Since then, O’Kelly has not only established a successful design career but also been instrumental in developing a patent-pending technology that began with the OSU 2011 competition house.

The U.S. Department of Energy Solar Decathlon captures the attention of millions of people worldwide. As partners of the event, Solar Decathlon sponsors share this spotlight and gain outstanding exposure—onsite, online, in print, and over the air.

Editor’s Note: This post is one of a series of technology spotlights that introduces common technologies used in U.S. Department of Energy Solar Decathlon team houses.

Good ventilation is vital for maintaining healthy indoor air quality. Houses built to modern energy efficiency standards, such as U.S. Department of Energy Solar Decathlon competition houses, are tightly constructed to allow very little outside air to leak in. As a result, odors, chemicals, particles, and humidity can become trapped, increasing indoor air pollution.

A house is just a building until people live in it. Then it becomes a home.

Although U.S. Department of Energy Solar Decathlon houses are not lived in during competition, Solar Decathlon visitors may ask themselves whether they could be comfortable homes when stepping through their thresholds.

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.

U.S. Department of Energy Solar Decathlon sponsors know a good thing when they see it. After all, the Solar Decathlon is more than an award-winning competition and highly popular public exhibit. It’s also a proven workforce development program that prepares collegiate students for careers in clean energy. The Solar Decathlon uses blended methods (including classroom instruction and real-world application) to teach science, technology, engineering, and mathematics (STEM) for building systems design and operation.

Not consuming energy is better than buying or producing it—even when that energy is generated by clean, renewable solar. That’s the message the U.S. Department of Energy Solar Decathlon 2015 is sending to decathletes through the Energy Balance Contest, which measures the energy each team house produces and consumes over the course of the competition.
