The Jess S. Jackson Sustainable Winery Building (JSWB) is designed to be a completely passive support building for the adjacent Research Winery and August A. Busch III Brewery and Food Science Laboratory (BWF). The building houses equipment and renewable energy systems to help the BWF achieve its goals for net-zero energy and net-zero water. The JSWB is designed to fit into the campus context through form and materials.
Davis is a cooling dominated climate with extreme summer temperatures. The design strategies for the JSWB are simple: employ building orientation, building form and a super-insulated envelope to minimize heat gain, then use thermal mass to help cool the building throughout the day and natural ventilation to flush the building at night. The roof form is dual purpose: deep porches at the east and west facades shade the building and increase roof area for photovoltaic array. The flat roof provides an ideal place for a future concentrating solar system and provides a staging area for the upper roof.
The key to a building's long-term value is its ability to adapt. The building will eventually house a range of process equipment that is currently unknown, but which is likely to add internal heat gains. To plan for adaptation, the building is outfitted with radiant tubing for a future radiant cooling system, as well as a ducting system to be used with a future rock bed.
