University of California, Davis, Readies Aggie Sol for Farmworkers

July 21, 2015

By Ernie Tucker

The University of California, Davis, has strong pedigrees in both sustainable projects and agricultural research.  So even though Solar Decathlon 2015 is the first U.S. Department of Energy Solar Decathlon for the school, its Aggie Sol house already has a legacy to draw upon. Its sports teams are dubbed the Aggies for the school’s agricultural and sustainable bent, and its Solar Decathlon 2015 project reflects that mission.

“Sol means the motivation, innovation, and pride that come with being a UC Davis student,” says Robert Good, a civil engineering graduate who is now the team’s project manager.

That pride stems, in part, from the early 1970s, when the school built a series of residential structures called the Domes, which focused on alternative lifestyles and sustainability. In the past six years, there have been several additional initiatives to create sustainable housing, including the West Village on campus, said to be the largest planned net-zero energy community in the United States. In a symbolic gesture, Aggie Sol is being assembled across from the Domes on campus.

“We’re dedicating the design to the needs of farmworkers or agricultural workers,” Good says. “The engineering, the architecture, and the entire focus of our team are dedicated to achieving this goal while achieving an affordable price point.”

The team is aiming for below-market-rate costs for its design, a concept that could make it more easily affordable to people who might have a critical need for such housing.

“We are making it affordable for the masses and workers,” Good says. “We saw the 2015 competition as an opportunity to approach that problem.”

Just under 1,000 ft 2, the wooden structure uses thick straw-bale walls that have a high R-value. To reduce both cost and energy consumption, the plumbing system will rely on gravity instead of pumps for water distribution to the fixtures.

The house is split into a double-wide modular layout, which the team believes will make it easy to fabricate, ship, and erect onsite. After the Solar Decathlon, it can be set up on a farm site.  Half of the space is in the style of a common “great family room,” combining a kitchen, dining room, and family room in one space for large group gatherings.

The other side is unique, Good believes. Along with private space that includes two bedrooms will be a mud room for workers to quickly clean up when they come home from outdoor field work. This includes a deck space, locker to store work clothes and muddy boots, laundry, and shower. Another locker holding clean clothes will enable the Aggie Sol resident to change and enter the house refreshed and dirt-free—a boon for those in farming occupations.

Aggie Sol is a university-wide project. So far, more than 300 students—from virtually all majors across the university, from engineering to English—have participated.

To overcome early organizational issues, they transformed the team setup to make it less formal.

“It was more fun to open up the discussions to anyone to participate. People could be less sensitive to the design critiques, which allowed us to sand the corners of our design down to something that really does work and effectively meets the project needs,” Good says.

The final location of the Aggie Sol house is still undecided. Local farm owners in the area have expressed interest, as have agricultural researchers, Good says.

Reaction has been strongly positive.  From the administration through the student body, “This has really made an impact on the university,” Good says.

He thinks Aggie Sol work will take root in the school curriculum, across the state, and beyond.

Yale University Seeks an Open Approach in Y-House

July 13, 2015

By Ernie Tucker

Although founded more than three centuries ago, Yale University is in its first Solar Decathlon this year. The team members had to scramble to make up for lost time. When they began their U.S. Department of Energy Solar Decathlon 2015 project nearly two years ago, the team consisted of eight inexperienced freshmen and sophomores.

“None of us has built a house before,” says Kate McMillan, co-project manager.

There were many moments when the crew seemed to hit dead ends—not enough time, money, experience, or backing—and yet somehow plowed through.

“But that’s one of the purposes of the competition. You start out with students who don’t have experience, and by the end of a year and a half, it’s crazy how much you do know,” McMillan says.

The team was fortified last semester by an infusion of grad students who were helping teach a class and then stayed on to advise.

“That really helped us to have people who have built houses,” says team member Thaddeus Lee. “They told us we needed to think about going modular in the design.”

The expanded group of about 15 participants also decided to take advantage of the ambient breezes in the California climate, making the house site-specific.

As a result, there’s nothing elite or Ivy League about the approach to what they call the Y-House. Instead, the compact 750-ft2 shotgun-style structure is designed to reduce material costs and energy loads while giving the impression of spaciousness by integrating outdoor space. Natural ventilation will be maximized across the north-south axis of the house. Vents above the kitchen and bathroom areas allow for hot air to escape to lower mechanical cooling loads.

The structure is geared for young professionals, who can enjoy a deck and trellised patio that effectively doubles the indoor space and forms a link to the outside, connecting to the community.  Photovoltaic panels will be on the trellis, which can be used separately as a standalone feature in the future.

“We entered this competition with the idea that, while the competition is great, we could drive the greater mission of sustainability with our building. Looking past the competition, we wanted a house we could retrofit and bring back to New Haven [Connecticut],” says Juan Pablo Ponce De Leon, project manager.

Still, gearing the Y-House for California doesn’t mean the influences of New Haven and New England are lacking.

“There’s a large tradition of outdoor patios if you walk around campus and town” that informs the house layout, Ponce De Leon says.

The basic building concept is to employ modular construction by working with a housing manufacturer in Oregon. The team will add components, including a solar panel racking system and lumber from a Yale forestry site to complete the project. Furnishings will be simple to allow for ease of configuration.

All the mechanical equipment will be in a module that will slot into the house. This “technopod”—which includes the bathroom, mechanical room, kitchen, and car-charging station—can be prefabricated and connected to the rest of the structure. And that’s where the fabled Old Blue network paid off. A Yale alumnus in the sustainable housing field is working with them on that aspect of the project.

The team is proud of how far it has come—and how much impact it might have.

“If undergraduates with no prior experience can design, build, and ship a net-zero house in under two years, it is exciting to imagine how our current generation might tackle issues of sustainability,” McMillan says.
