This was a graduate student project by Nicholas James Jr. Munoz for Michael Cadwell's ARCH 841 / ARCH 842 courses, Autumn 2005 / Winter 2006. This project is a study of a sustainable floor system in which a concrete labyrinth is employed below grade as a thermal battery through which air is circulated. The walls of the Labyrinth extend upward through the floor to create an interior landscape of program and structure. ---- Nicholas James Jr. Munoz This work is a part of the online collections of the Knowlton School of Architecture Student Archives, The Ohio State University.
