CAAD Futures is a biennial conference that aims to promote the advancement of computer-aided architectural design research and teaching. The conferences are organised under the auspices of the CAAD Futures Foundation. The conference series started in 1985 in Delft and has since traveled to major cities in Europe, Asia, and USA. This volume is the proceedings of the 12th International Conference of CAAD Futures, which took place in Sydney, Australia. The internationally refereed papers in this book present the state of the art in computer-aided architectural design research. The papers in this year's conference theme, Integrating Technologies for Computer-Aided Design, provide the technological foundation for new ways of thinking about using computers in designing and the use of computers in design itself as well as in the education of designers.
