The U.S. Department of Energy Solar Decathlon is an international collegiate competition made up of 10 contests that challenge student teams to design and build full-size, solar-powered houses. The winner of the competition is the team that best blends design excellence and smart energy production with innovation, market potential, and energy and water efficiency.

The first Solar Decathlon was held in 2002. The competition has since occurred biennially in 2005, 2007, 2009, 2011, 2013 and 2015.^[1] The Solar Decathlon 2017 will be located in Denver, Colorado, adjacent to the 61st & Peña station on the University of Colorado A line commuter train connecting Denver International Airport to downtown Union Station. In addition to the competition, Solar Decathlon 2017 will also feature a sustainability expo, professional development and consumer workshops, middle-school education events, and a community festival.^[2]

Open to the public and free of charge, the Solar Decathlon allows visitors to tour energy- and water-efficient houses, and gather ideas to save energy and conserve water in their own homes.

The Solar Decathlon 2017 competition is presented by the U.S. Department of Energy and administered by Energetics, Incorporated, a subsidiary of VSE Corporation. Previous competitions were administered by the National Renewable Energy Laboratory (NREL).

Since the first competition in 2002, the Solar Decathlon has expanded internationally to include four additional worldwide competitions in Europe, China, Latin America and Caribbean, and the Middle East. Solar Decathlon Europe was established under a 2007 memorandum of understanding between the United States and Spain , which hosted competitions in 2010 and 2012. France hosted in 2014.^[3] The Solar Decathlon China was established with the signing of a memorandum of understanding between the U.S. Department of Energy, China’s National Energy Administration, Peking University and Applied Materials on January 20, 2011.The first Solar Decathlon China took place in August 2013 in the city of Datong. The next Solar Decathlon China will take place in summer 2017 and was formed through a memorandum of understanding among the United States Department of Energy, the People’s Republic of China, and the China Overseas Development Corporation.^[4][5]

Solar Decathlon Latin America and Caribbean was established under a memorandum of understanding between the United States Department of Energy and the government of Colombia in 2014. The first competition was held in Cali in December 2015.

Solar Decathlon Middle East, to be held in Dubai, United Arab Emirates, in 2018, was formed by a memorandum of understanding between the United States Department of Energy and the Dubai Electricity and Water Authority in 2015.

History

The Solar Decathlon 2011 was held in the National Mall’s West Potomac Park in Washington D.C.

The inaugural Solar Decathlon was open to the public between September 19 and October 6, 2002. Fourteen teams from across the United States, including Puerto Rico, presented their projects on the National Mall in Washington, D.C. The University of Colorado was awarded first place. At the second Solar Decathlon, likewise held on the National Mall on October 6–16, 2005, eighteen teams from the United States, Canada, and Spain participated; the University of Colorado successfully defended its championship.

The third Solar Decathlon took place on the National Mall on October 12–20, 2007. Twenty teams from the United States, Canada, Spain, and Germany competed, and Technische Universität Darmstadt (Team Germany) was named the overall champion. The fourth Solar Decathlon was held on the National Mall on October 8–18, 2009, and included teams from the United States, Canada, Germany, and Spain; Team Germany was named the winner for a second time.

The fifth Solar Decathlon took place between September 23 and October 2, 2011, with nineteen participating teams representing the United States, China, New Zealand, Belgium, and Canada. The event was held in Washington D.C.'s West Potomac Park, near the Potomac River, the Tidal Basin and the Franklin Delano Roosevelt Memorial, along a road between the Lincoln and Jefferson Memorials.^[6] The University of Maryland was the overall competition winner.^[7] The sixth Solar Decathlon took place on October 3–13, 2013, in Orange County Great Park in Irvine, California – it was the first Solar Decathlon to take place outside Washington D.C., and was won by Vienna University of Technology (Team Austria).^[8][9] The seventh Solar Decathlon was held October 8 – 18, 2015, also at the Orange County Great Park. Stevens Institute of Technology was the overall winner. This was their third Solar Decathlon competition.

Awards

In 2010, the National Building Museum awarded the Solar Decathlon an Honor Award for its emphasis on "renewable energy, energy-efficient, and environmentally responsible systems" and its role in "educating a new generation of built-environment professionals".^[10]

Scope of contests

Like the Olympic decathlon, the U.S. Department of Energy Solar Decathlon consists of 10 contests. The contests evaluate cost-effective design; innovation balanced with market potential; water and energy efficiency; energy production and time-of-use energy; and communications strategies. Each Solar Decathlon contest is worth a maximum of 100 points, for a potential competition total of 1,000 points. Teams earn points through task completion, performance monitoring, and jury evaluation.

Contest 1: Architecture

For the Architecture Contest of the U.S. Department of Energy Solar Decathlon 2017, teams are required to design and build attractive, high-performance houses that integrate solar and energy efficiency technologies seamlessly into the design.

Contest 2: Market Potential

For the Market Potential Contest of the U.S. Department of Energy Solar Decathlon 2017, each team is required to design a primary residence for year-round occupancy for a specific target client of its choosing..

Contest 3: Engineering

Solar Decathlon houses are marvels of engineering. For the U.S. Department of Energy Solar Decathlon 2017, a jury of engineers will evaluate the engineering design and implementation of each team's house based on the following criteria: Approach, Design, Efficiency, Performance and Documentation.

Contest 4: Communications

The U.S. Department of Energy Solar Decathlon 2017 teams must develop and implement communications strategies to engage their local communities, provide free tours to visitors during the event in Denver, and make an impact across the world through their digital presence and media outreach.

Contest 5: Innovation

New for the U.S. Department of Energy Solar Decathlon 2017, the Innovation Contest encourages teams to take a thoughtful approach to innovation, rather than being limited solely to off-the-shelf solutions.

Other contests, such as Market Potential, provide further checks and balances to ensure innovative ideas are implemented within market realities.

Contest 6: Water

Always ahead of their time, past Solar Decathlon teams have consistently integrated water use and reuse strategies into their designs, even though no points were awarded for this effort. Now, the U.S. Department of Energy Solar Decathlon 2017 is rewarding smart water solutions for the first time.

This new contest is important not only because water is a precious resource, but also because water and energy are inextricably linked—it takes water to make the energy we use, and it takes energy to treat and deliver the clean water we require.

Contest 7: Health and Comfort

New for 2017, the U.S. Department of Energy Solar Decathlon Health and Comfort Contest combines new contest components with those from previous Solar Decathlon competitions. Teams are challenged to build a house that minimizes the flow of cooled air in summer or heated air in winter to the outdoors, operate heating and cooling systems that keep temperature and humidity steady, all while maintaining healthy indoor air quality.

Contest 8: Appliances

The U.S. Department of Energy Solar Decathlon 2017 Appliances Contest is designed to mimic the appliance use of an average U.S. home. Teams earn points for operating their refrigerator and freezer, washing and drying laundry, simulating cooking tasks and hot showers.

Contest 9: Home Life

The Home Life Contest in the U.S. Department of Energy Solar Decathlon 2017 demonstrates whether or not a house is capable of being a home. Teams are required to engage in a variety of activities just like real homeowners. They share meals with friends and neighbors, watch television, use their computers, and host games nights. They even commute in an electric vehicle charged from the house's solar electric system.

Contest 10: Energy Contest

The Energy Contest of the U.S. Department of Energy Solar Decathlon 2017 evaluates each team's energy production and a theoretical value to a utility of the energy they both contribute to and take from the Solar Decathlon electricity grid.

For energy production, teams receive full points for producing at least as much energy as its house needs, thus achieving a net energy consumption of zero during the competition.

The energy value component of the Energy Contest is designed to mimic the arrangement a consumer with a solar-powered house may have with a utility, including a net-metering agreement and time-of-use electricity rates.
