The Building Technology Program at the Massachusetts Institute of Technology (MIT) is an interdisciplinary program, bringing together researchers from the Department of Architecture, the Department of Civil and Environmental Engineering, and the Department of Mechanical Engineering. Their projects focus on the building industry, which represents "one of the largest enterprises in the country" and innovations in building technology. This website provides links to information on several research projects, such as a project "to explore design, technology and implementation of environmentally responsive urban housing in China" and others that explore options for naturally ventilated buildings. Another project website describes recent research in Masonry Structures, while The MIT Design Advisor offers and online design tool for architects and building engineers.
