The iA, or Interactive Architecture, bookzine series will consist of 12 issues bi-annually, published over a period of six years under the supervision of Kas Oosterhuis, director of Hyperbody at the Delft University of Technology and principal of ONL [Oosterhuis Lénárd]. The Interactive Architecture (iA), concept is based on the equal input (listening), process (thinking), and output (talking) of people as well as the built components of architecture. This will be one of the first publications to document in detail this groundbreaking new development in architecture. iA will undoubtedly become the premier archive of this endeavor. The publication program will consist of scientific papers on particular aspects of iA and iA-driven MSc projects, iA-inspired case studies from practice, interviews with a renowned researcher/practitioner, and blogs by Kas Oosterhuis. The inaugural issue features contributions from Cas Aalbers, Henriette Bier, Nimish Biloria, Michael Bitterman, Sven Blokker, Sander Boer, Christian Friedrich, Hans Hubers, Xin Xia, and others.
