Student-built houses powered exclusively by solar power on display in Washington D.C. at the Solar Decathlon 2009.

The U.S. Department of Energy (DOE) 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, 2015 and 2017.[1] The Solar Decathlon 2017 was 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 also featured a sustainability expo, professional development and consumer workshops, and middle-school education events.[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 was presented by DOE 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 competitions in Europe, China, Latin America and Caribbean, the Middle East, and Africa.[3] 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.[4] The next Solar Decathlon Europe is planned for 2019 in Szentendre, Hungary.[5]

The Solar Decathlon China was established with the signing of a memorandum of understanding between DOE, 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 2018 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.[6][7]

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, and another competition is planned for 2019.[8]

Solar Decathlon Middle East, to be held in Dubai, United Arab Emirates, in 2018, was formed by a memorandum of understanding between DOE and the Dubai Electricity and Water Authority in 2015. An additional Solar Decathlon Middle East is also expected to take place in 2020.[9]

On November 15, 2016, the Moroccan Ministry of Energy, Mines, Water, and the Environment (MEMEE); the Moroccan Research Institute in Solar Energy and New Energies (IRESEN); and DOE signed a memorandum of understanding to collaborate on the development of Solar Decathlon Africa. The competition is planned for 2019.[10]

HistoryEdit

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, 18 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.[11] The University of Maryland was the overall competition winner.[12]

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).[13][14]

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.

The eighth Solar Decathlon in the U.S. was held October 5–15, 2017, in Denver, Colorado, at the 61st & Peña Station on the University of Colorado A line commuter rail connecting Denver International Airport to downtown Union Station. Eleven teams competed to design, build, and operate the most cost-effective, energy-efficient, and attractive solar-powered house. The Swiss Team won the overall competition with their entry, NeighborHub. It was the first entry for this combined team of École Polytechnique Fédérale de Lausanne, School of Engineering and Architecture Fribourg, Geneva University of Art and Design, and the University of Fribourg.

AwardsEdit

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".[15]

Scope of contestsEdit

Like the Olympic decathlon, the DOE 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. The contests may change after each competition in response to participant feedback, market dynamics, and DOE goals. The contests below were featured in Solar Decathlon 2017.

Contest 1: ArchitectureEdit

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

Contest 2: Market PotentialEdit

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

Contest 3: EngineeringEdit

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

Contest 4: CommunicationsEdit

The Solar Decathlon 2017 teams were required to 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: InnovationEdit

New for Solar Decathlon 2017, the Innovation Contest encouraged teams to take a thoughtful approach to innovation, rather than being limited solely to off-the-shelf solutions. Other contests, such as Market Potential, provided further checks and balances to ensure innovative ideas were implemented within market realities.

Contest 6: WaterEdit

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. Solar Decathlon 2017 rewarded smart water solutions for the first time. This new contest was 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 ComfortEdit

New for 2017, the Health and Comfort Contest combined new contest components with those from previous Solar Decathlon competitions. Teams were 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: AppliancesEdit

The Appliances Contest was designed to mimic the appliance use of an average U.S. home. Teams earned points for operating their refrigerator and freezer, washing and drying laundry, and simulating cooking tasks and hot showers.

Contest 9: Home LifeEdit

The Home Life Contest in Solar Decathlon 2017 demonstrated whether or not a house was capable of being a home. Teams were required to engage in a variety of activities just like real homeowners. They shared meals with friends and neighbors, watched television, used their computers, and hosted games nights. They even commuted in an electric vehicle charged from the house's solar electric system.

Contest 10: Energy ContestEdit

The Energy Contest evaluated each team's energy production and a theoretical value to a utility of the energy they both contributed to and took from the Solar Decathlon electricity grid. For energy production, a team received full points for producing at least as much energy as its house needed, thus achieving a net energy consumption of zero during the competition. The energy value component of the Energy Contest was 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.
