Wine industry leaders and design-build contractors gathered at the University of California, Davis, in late May to celebrate the opening of the $4 million Jess S. Jackson Sustainable Winery Building. It pines to be the first building at any university to be certified “net zero energy<\/a>” under the Living Building Challenge<\/a>, and only the second such building in California.<\/p>\n

The simple and sleek 8,500-square-foot structure is next door to UC Davis’ three-year-old Teaching and Research Winery and August A. Busch III Brewing and Food Science Laboratory. Located at the Robert Mondavi Institute for Wine and Food Science<\/a> complex on the south side of the core campus, visible from Interstate 80, the two existing buildings were the first of their kind to receive LEED Platinum certification from the U.S. Green Building Council. The new adjacent sustainable winery building will eventually house equipment and systems for capturing and sequestering carbon dioxide from wine fermentation, and for filtering and recirculating water for wine, beer and food processing at those facilities.<\/p>\n

“What you see in this building is the potential to achieve levels of sustainable operation never before seen in a commercial or research winery,” said David Block, chair of the UC Davis Department of Viticulture and Enology.<\/p>\n

The one-story building contains 10 modular spaces designed to accommodate equipment for a variety of processes, including high-purity filtration of rainwater for use in cleaning fermentors and barrels in the winery. Ninety percent of the water and chemistry from each cleaning cycle will be captured, filtered through a semi-permeable membrane and reused in multiple cleaning cycles, the university claims.<\/p>\n

In spite of all the hoopla, the building’s featured systems aren’t ready yet. The water filtration and recirculation system is expected to be installed in 2014, and a system for sequestering carbon dioxide captured from all fermentations in the winery is set to follow. The carbon dioxide collected from the fermentations will be converted into calcium carbonate, or chalk, once the sequestration system is completed.<\/p>\n

The new building also will be equipped to produce chilled water using a solar-powered ice maker, and to generate hydrogen gas by electrolysis, fueling a hydrogen fuel cell for nighttime energy use. <\/p>\n

[pagebreak]<\/strong>One room in the new building will house the control system and data hub for the many processing systems, and two areas will be held for future research projects and equipment trials related to any aspect of water and energy use or sustainable systems.<\/p>\n

“Because of the building’s flexible design, these and each of the other operating systems can be removed and updated as research advances become commercially available,” said Roger Boulton, an enology<\/span> professor at UC Davis.<\/p>\n

Davis is known for its cooling-dominated climate with extreme summer temperatures that can reach 102 degrees. The winery building is super-insulated, meeting R-59.5 insulation standards in the walls and R-76 in the roof, minimizing the heat in the building’s interior. Roof overhangs on the east and west sides of the building form deep porches, protecting the structure against the sun. In the evening, natural ventilation flushes warm air out.<\/p>\n

The roof area was also increased to support a photovoltaic array that can be expanded for future energy demands of the adjacent winery, brewery and food-processing plant. The building’s slab contains a tube system that will allow cold water to provide additional cooling in summer and hot water to provide winter heating, as well as pipework for a future, below-ground rock bed that will provide additional thermal mass to offset heat released from the various installed systems.<\/p>\n

“The building’s combination of good basic design, the integration of advanced technologies and a well-thought-out plan for the future have laid a path toward achieving net zero energy building certification over the next year,” said Jim Coyle, senior project manager at Oakland-based Pankow Builders.<\/p>\n

In order to decrease the carbon footprint of the new building, concrete blocks that permanently sequester carbon dioxide were used, along with a 90-percent cement replacement mix. <\/p>\n

The site itself was designed to be easy to maintain, with elements that include a pollinator garden, no-mow grasses, lower albedo surfacing and “naturally paved” driveways.<\/p>\n

[pagebreak]<\/strong>Partners on the project, made possible by a $3 million pledge from the late Jess Jackson and his wife, Barbara Banke, proprietor of Jackson Family Wines. include the design-build team of Pankow Builders<\/a>, Siegel & Strain Architects<\/a> and Guttman & Blaevoet Engineering<\/a>. The performance of the building’s commissioned systems— such as electrical, HVAC and renewable energy technologies—were verified through a third-party quality assurance manager, Environmental Building Strategies<\/a> (EBS). The project’s groundbreaking was in November 2011.<\/p>\n

The opening of UC Davis’ Sustainable Winery Building also coincided in the same week with the launch of the Zero Net Energy (ZNE) Center 80 miles away in San Leandro. A project EBS is also involved in, the ZNE Center is a training facility for chapters of International Brotherhood of Electrical Workers and National Electrical Contractors Association. When completed, the 46,000-square-foot edifice, a rehab of a 1980s structure, will qualify as the largest zero energy building in California and the third largest in the United States, according to a June 5 post on Forbes.com<\/a> discussing the net zero building movement, which it calls a “nascent phenomenon.”<\/p>\n
