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.
