Two weeks ago, during the Solar Decathlon 2017 competition, we explored the solar powered house designs from participating university teams. The designs showcased many creative and resourceful design strategies—and presented a fun challenge for modeling in Aurora.

With the competition now complete, today’s post takes a closer look at the top three teams to identify some of the solar design lessons from their success.

Prestigious Energy Competition Open for Final Weekend

DENVER, CO – Acting Assistant Secretary for Energy Efficiency and Renewable Energy Daniel Simmons today announced the winning team of the U.S. Department of Energy (DOE) Solar Decathlon 2017 in Denver, Colorado. The Swiss Team took first place overall by designing, building, and operating the house that best blended smart energy production with innovation, market potential, and energy and water efficiency. The University of Maryland took second place followed by the University of California, Berkeley and University of Denver team in third place.

Stevens Institute of Technology won top honors overall at the U.S. Department of Energy Solar Decathlon 2015 by designing, building, and operating the most cost-effective, energy-efficient, and attractive solar powered house.

University at Buffalo, The State University of New York, took second place followed by California Polytechnic State University, San Luis Obispo, in third place.

Blaise Stoltenberg, a U.S. Department of Energy Solar Decathlon organizer, developed his vision for a clean energy future as a Solar Decathlon 2002 decathlete. He was a leader of the University of Colorado's winning 2002 team and, in recent years, served as a coordinator for Solar Decathlon engineering juries. He did it all with a kind and giving spirit that inspired colleagues and friends.

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.

Team Austria from the Vienna University of Technology has won the U.S. Department of Energy Solar Decathlon 2013.

The results of three contests were announced at Solar Decathlon China this morning. Teams gathered in the auditorium of the Sun Palace, and jury members announced the first, second, and third place for Engineering, Communications, and Market Appeal. The results are:

Wowing jurors with its attention to detail, craftsmanship, and unusual energy visualization system, New Zealand (Victoria University of Wellington) received first place today in the U.S. Department of Energy Solar Decathlon 2011 Engineering Contest for its First Light house.
