The Center for Environmental Design Research is an Organized Research Unit of the University of California at Berkeley. Located in the College of Environmental Design, the Center assists the research of faculty, students, and others interested in the design and planning of the built environment. The Center's mission is to encourage research in environmental planning and design, in order to increase the factual content of design decisions and to promote systematic approaches to design decision-making. The scope of our research ranges from local human environments to regional ecosystems, from details of building construction to large-scale urban planning, and from the history of the built environment to the design process itself.
