rooms. The Guest House is located on-campus and the Vineyard Lodges are about from the campus, with shuttle service to and from the buildings. The campus' newest residence hall, Vineyard Lodge II, was built around 2009 as the campus expected to double its enrollment. The building has two-stories, 31 dorm rooms, a kitchen, an activity room, an outside deck and two manager's rooms. The school planned for an environmentally-oriented dormitory, with solar panels to cover some of the building's electrical needs, as well as a membrane system for waste water. The building also has board and batten siding, which lasts longer than wooden siding. The building, on Pratt Avenue in St. Helena, is the first building in the city to be metal-framed rather than wood-framed, to better prevent termites, mold, and fire. The school estimated costs of $4 million for a Napa-based construction company to construct the building. The company demolished a laundry and facilities building in what was described as a green-oriented process. At the time of construction, the school annually enrolled 104 students; the new residence hall would allow the campus to enroll another 100 students. Other facilities The De Baun Theatre is a 48-seat demonstration kitchen that hosts cooking demonstrations for the public. The Ecolab Theatre is a 125-seat amphitheater-style demonstration auditorium that rises through the first two levels of the building. It is designed for cooking demonstrations, lectures, food and wine tastings, and other special events. The auditorium's demonstration kitchen has a cooking center, large video monitors, and fixed tables at every seat. The Rudd Center for Professional Wine Studies, a two-story distillery building dating to around 1889, is used for the Professional Wine Studies program and was named after the Rudd family of Rudd Farms. The building has sensory analysis classrooms with wireless keypad response systems, built-in light boxes, and expectoration stations. The Rudd Center contains a pantry, a 4,000-bottle wine cave and private dining room, and a terrace. Karen MacNeil is the creator and chairman of the center. The building opened in 2003 for a wine professional credential; the school began its wine and beverage certification program in 2010. In 2013 the school began a wine, beverage, and hospitality concentration in its bachelor's degree program. The Spice Islands Marketplace is the campus store, and offers culinary-related items (cooking equipment, cookbooks, uniforms, and food ingredients). Next to the store is a flavor bar that holds
