UC Davis is the place to go if you want to learn how to make wine, brew beer or grow great produce, and the school is dedicated to sustainability to boot. The most recent addition to their super sustainable campus is the Jess Jackson Sustainable Winery Building - a net-zero and passively-designed auxiliary warehouse meant for equipment and processes. Designed by Siegel & Strain Architects, the huge roof is now outfitted with a 5 kW solar system, which is more than enough energy needed for the building. Over time though there are plans to add even more photovoltaics and a concentrated solar system that will provide more energy for the rest of the campus.
The 8,500 sq ft Jess Jackson Sustainable Winery Building is the latest addition to UC Davis Winery, Brewery and Food Science Facilities in the central valley of California. We wrote last year about the LEED Platinum campus that collects enough rainwater to irrigate the vineyards. The Jess Jackson building is a support facility to house equipment and run more processes for wine and beer making. But even more importantly, the building acts as a solar powerhouse for the rest of the campus.
Siegel & Strain Architects led the team of builders and engineers to design an energy efficient facility that needs no air conditioning despite summer temperatures that reach over 100 degrees. First the building is oriented for solar passive design with large roof overhangs to provide shade on the east and west. Clerestory windows provide natural daylight and operable windows, and big fans help flush the building and cool it at night. The very tight envelope features a very high level of insulation. In fact, a blower door test confirmed that the facility achieves Passive House standards for air infiltration.
Also impressive is the choice of materials for the facility’s construction. A prefab steel structure lowered costs and allowed construction to proceed quickly. The concrete used for the slab and the concrete masonry units permanently sequesters carbon dioxide and is the first installation of Basalite’s Carbon Cure blocks. Then the large sloping roof features a 5 kW photovoltaic system that provides more than enough energy for the building. Over time, more PV panels will be added along with a solar concentrating system to generate more power for the entire campus. There are also plans to install radiant cooling and an innovative, passive rock bed cooling system to further reduce indoor temperatures.
“What you see in the Jess S. Jackson Sustainable Winery Building is the potential to achieve levels of sustainable operation never before seen in a commercial or research winery.” said David Block, Chairman at the Department of Viticulture and Enology at UC Davis. The building was designed to adapt over time and serves as the framework for new, sustainable technologies.
