The newest addition to the residential facilities at CSB, Centennial Commons opened for business with the 2012-2013 school year. Centennial Commons provides two-story, townhome style housing for 124 students and one full-time residence director. Each fully furnished apartment accommodates four students and includes four bedrooms, two bathrooms, laundry, living room, kitchen and front porch. The housing complex also includes a Commons Building that provides the community with gathering space, study rooms, computer lab, kitchen and a multi-purpose room. Centennial Commons was built with sustainability in mind. The complex "meets the standards of at least silver certification" in LEED (Leadership in Energy and Environmental Design) classification, according to Judy Purman, CSB's director of sustainability. The design engineering is as efficient as possible - high efficiency windows and furnace, natural daylight harvesting, low-flow plumbing, and exterior LED light fixtures.
