This chapter presents case studies that include a range of buildings selected to provide a diversity of geographic locations, climates, building types, and green strategies. The design teams for these projects have made strong statements about green design intentions and have provided fertile ground for designers to learn from their projects. Each case study describes an outstanding project that integrated green strategies via an informed design process. All the projects offer informative lessons for future projects. The design intent for Centre For Mathematical Sciences (CMS) was to create a building that encouraged occupant interaction and facilitated the crossing of disciplinary boundaries. The team developed an organizational scheme whereby social space was located at the core of the complex—along main circulation routes—and in which users experience increasing layers of privacy until they reach their individual office in one of the ancillary pavilions.
