MEDIATED ARCHITECTURE: Vivid, Effervescent and Nervous, the second issue of the SAC JOURNAL, presents three projects de- signed at SAC during the last eight years. The three projects are: The Theatre of Immanence (2007), an installation and exhibition project in Städelschule's Portikus gallery; Digital Bodies (2013-14), an experimental research project; and Orkhstra (2014), which was an installation on a large, public square in Frankfurt and part of Luminale, 'Biennale of Lighting Culture'. The projects vary in scale and nature from gallery installation via laboratory-style modelling experiment to an urban intervention. They span a period in which architecture's contribution to the production of space has become increasingly me- diated by technology. Each in their own way, the three projects probe this condition and explore new design opportunities given to archi- tecture. The results are vivid, effervescent and nervous and always a mediated architecture. Accompanying extensive portfolios of drawi- ngs and pictures that document the respective design processes and their results, are texts that expound on the theoretical and practical implications of each project

Text contributors to SAC JOURNAL No. 2 include: Sanford Kwinter, Daniel Birnbaum, Maraike Bückling, Sebastian Oschatz, Mathias Wollin, Peter Trummer, Mirco Becker and Johan Bettum. SAC JOURNAL is a publication series that addresses topical issues within architecture. The journal documents, critically reviews and also presents theoretical discussions concerning contemporary design and research. The content of SAC JOURNAL is produced by invited contributors and students and faculty at the Städelschule Architecture Class.
