Visit Solar Decathlon’s First Virtual Village to Tour One-of-a-Kind, High-Performance Homes Online!

Monday, March 29, 2021

The U.S. Department of Energy is excited to announce the opening of the U.S. Department of Energy Solar Decathlon® Virtual Village – now live and open to the public!

The Virtual Village will showcase zero energy homes designed and constructed around the world by Solar Decathlon 2020 Build Challenge teams. Industry partners, schools, future collegiate teams, and the interested public are invited to participate in no-cost, virtual tours of the homes, hosted by participating teams.

Visitors can experience these one-of-a-kind homes in this first-ever Solar Decathlon Virtual Village “located” on the National Mall, where the first Solar Decathlon event was launched in 2002.

Visitors can also participate in a Solar Decathlon home scavenger hunt, and a toolkit will be available to help teachers bring students to the Virtual Village for unique educational activities.

Live virtual home tours with student teams will occur at the following times:

The 2020 Build Challenge Competition Event and public exhibition were previously scheduled to take place on the National Mall in the summer of 2020, with each team’s house included in the constructed village for public tours. Due to the coronavirus (COVID-19) pandemic, the 2020 event was postponed and transitioned to a local build event, with teams constructing their homes in their local communities where they will remain after the competition. Moving forward, Solar Decathlon Build Challenge teams will follow this local build model, with the next competition scheduled for 2023.

Achieving Zero Energy While Meeting Unique Homeowner Needs

Thursday, March 4, 2021

A 100% clean energy economy capable of battling climate change will include a strong foundation of zero energy homes—a house that can produce as much energy as it uses. Such homes don’t have to be bare-bones and uncomfortable. Quite the opposite, in fact. Student-led teams competing in the U.S. Department of Energy Solar Decathlon® Build Challenge are proving they can blend architectural design and engineering excellence with innovation, market potential, building efficiency, and smart energy production, all with the “comforts of home.”

Mojave Bloom: A Therapeutic Home for Post-Traumatic Healing

Tuesday, December 22, 2020

Architects are really good at a lot of things, but one quality in particular stands out to Eric Weber, an Associate Professor of Architecture at the University of Nevada Las Vegas (UNLV). He believes that once architects understand the nature of a challenge, they excel at developing thoughtful responses to it. Maybe that is why Weber’s Design + Build students chose to create a home that supports veterans dealing with post-traumatic stress disorder (PTSD) for their U.S. Department of Energy Solar Decathlon® 2020 Build Challenge entry, Mojave Bloom.

Team Las Vegas includes four veterans, one service member’s spouse, and Weber himself who is a Desert Storm­ veteran of the U.S. Marine Corps. Furthermore, Las Vegas is home to many former service members due to its proximity to Nellis Air Force Base and the U.S. Air Force Warfare Center. The mission of finding solutions for the challenges that returning soldiers face not only hit close to home, but really resonated with the team.

How did participation in the Solar Decathlon affect the trajectory of your career?

I knew I was interested in zero energy buildings, but the Solar Decathlon cemented for me that I wanted to make this field my career. Furthermore,  as I started working with the multidisciplinary team I assembled for the Race to Zero, I realized the importance of an integrated design process. This was one of the reasons I ended up at the MIT Sustainable Design Lab for my master’s; the lab is multi-disciplinary and focused on tools and analyses that architects, engineers, and policy-makers can all understand.

 Describe a work outcome, building project or other achievement you are most proud of and how (if) it relates to your experience with Solar Decathlon.

At MIT, I have been working with other members of my lab to make urban building energy modeling tools accessible to every city so that they can make physics-backed decisions on how to meet their emissions reduction goals. Through Solar Decathlon trainings and collaborations, I learned the applied building physics that underlie every building upgrade strategy we propose to meet these emissions reduction goals.

Solar Decathlon Technology Innovation Blog Series: Building Enclosures

Thursday, December 3, 2020

This is the first in a monthly series on Solar Decathlon Build Challenge technology innovations, through which we will explore innovative technologies and strategies 2020 Build Challenge teams are employing in their houses. This month’s post focuses on building enclosures – or walls, windows, roof of the homes. Stay tuned for posts on indoor comfort, energy performance, water efficiency, and much more!

Since 2002, the Solar Decathlon has invited collegiate teams to design and build highly efficient and innovative buildings powered by renewable energy. As we ramp up to the Solar Decathlon Competition in April 2021, the new Solar Decathlon Tech Innovation blog series will highlight innovative products and strategies teams are employing in their homes to achieve competition goals. This edition focuses on building enclosures. We caught up with representatives from three Solar Decathlon student teams learn more about their unique approaches to walls, windows and roofs.

Kansas State University’s Net Positive Studio is a multiyear effort in which students pursuing a master’s in architecture work with local groups in Kansas City’s Historic Northeast neighborhood. The Kansas State team is developing a high quality energy-efficient home that is affordable for low-income households.

The Warrior Home team designed by the University of Waterloo team in Ontario, Canada, has completed a four-bedroom, single-family home to address the cultural and societal needs of families within the Chippewas of Nawash indigenous community in southwest Ontario.

The CampusCraft team at the University of Denver has undertaken the net-zero renovation of a single-family residence located in the Denver floodplain. CampusCraft has developed a cost-effective plan following Federal Emergency Management Agency (FEMA) guidelines to update a 1950s home with energy-efficient technologies.

What is your home’s enclosure technology or strategy, and why did it make sense for this house?

The Kansas State team went prefab, putting components together in their facility on-campus in Manhattan, Kansas, then moving them to the building site in Kansas City.

“Inside our panels, we have conventional wood-stick framing,” said Michael Gibson, an associate professor at Kansas State. “But I think the main difference is we’re using a polyurethane-based structural insulated panel (SIP) from Raycore. Their panels have foam with 2-by framing within the panel. And so we use that as our load-bearing structure—our walls—and then we put oriented strand board (OS) on the outside of that, and then continuous insulation on the outside of that. And then we use Huber’s ZIP System® on the outside as our weather barrier and an air barrier system.”

Meet Celcius: A Sustainable Home that Reflects the Students Who Built It

Friday, October 23, 2020

Three years ago, a group of students from the Netherlands focused on the concept of circularity in their entry to the U.S. Department of Energy Solar Decathlon® competition. Their entry, Selficient, showcased the benefits of a home designed to be endlessly recyclable, growing and reconfiguring to adapt to the homeowners’ needs at every stage in their lives. Selficient earned second place in the Market Potential Contest and seventh place overall.

Fast-forward to 2020. A new team from Hogeschool Utrecht (HU) University of Applied Science in the Netherlands is competing in the Solar Decathlon 2020 Build Challenge. Inspired by HU’s 2017 team, the new Netherlands team is further developing the concept of a house that has “Circular, Eye-opening, Limitless, Community, Innovative, Unconventional and Self-sufficient” (CELCIUS) as its building blocks. Together, Team Celcius is building a next-generation home that reflects these core values.

This computer rendering of the Celcius house represents the base unit that the HU team is building to compete in Solar Decathlon 2020. Because every component is interchangeable, every room scalable, and every pipeline movable, a target customer can begin living in this relatively simple version of the home and upgrade it over time.
