The Faculty of Architecture at Delft University of Technology is recognized as one of the most dynamic and innovative research and design schools in Europe and its graduation projects never fail to provide a new angle on design. The Architecture Annual offers a selection of articles charting the school's progress in research and education. This year a theme, 'Architectural Footprints', was added to the Research section of the Annual. Directly connected with the familiar 'ecological footprint', it resulted in several articles showing an innovative approach to sustainability. Includes articles on energy potential mapping and CO2 neutral cities and an interview with the Minister of Environmental Affairs, Jacqueline Cramer, to explain the political point of view and the implications of collaborating with universities.
