Oklahoma State University, Stillwater, Oklahoma The Architects Collaborative (TAC) in association with Frankfort-Short-Bruza, won a 4 firm invited national design competition for The 21st Century Center for Agriculture and Renewable Natural Resources to provide laboratory spaces, faculty offices, lecture rooms, a 280-seat auditorium, and a major interactive space for the departments of plant pathology, entomology, microbiology, bio-chemistry, and geology. The master plan established a new symbolic entrance to the campus, spatially ompleted the central library courtyard at the intersection of the major pedestrian crossroads of the campus and created a destination and identity for the facility along the north/south axis, providing a strong visual presence for the center and an appropriate contextual fit. Building design goals included the innovative use of active and passive solar energy conservation systems that provided the latest technologies enabling the project to become a state-of-the-art living laboratory facility with flexibility, adaptability and various levels of student and faculty interaction spaces. The unique laboratory design placed the write-up spaces in the projected bay window exterior wall, cantilevered into the shared exterior atrium solar courtyard under a light shelf reflecting daylight into the lab spaces. All faculty offices, support and core elements are placed outside of the lab areas along the pedestrian streets, encouraging forced and casual interaction of faculty and students.
