Following last’s year Smart Geometry conference, hosted in Barcelona, IAAC faculty Luis Fraguada and Tomas Diez and alumni Felipe Pecegueiro are leading the Urban Feeds cluster (assisted by MAA student Morten Bulow) at the Smart Geometry Workshops and Conferences 2011, which is taking place in Copenhagen from March 28th to 31st. Urban Feeds cluster aims to generate design responses that scrutinize and analyze the relationships between two or more sensor parameters. Like traffic lights with sensors that are programmed to respond to fluctuations in traffic flows, the cluster aims to prototype urban interventions. These ‘behavioral prototypes’ allow the participants to design explicit behaviors and their varying degrees of expression in relation to the input parameters. To achieve the challenge, Urban Feeds team pre-developed and produced the Ambience Sensor Kits (ASK) at Fab Lab Barcelona, supported and sponsored by IAAC. Smart Geometry 2011 > Building The Invisible Vast streams of data offer a rich resource for designers. User data, energy calculations, embedded sensing, material and structural simulation allows design to be situated and responsive. Design sits not separate from is environment but inhabits an ecological system, open, dynamic and interdependent. We now have the chance to instil design with an immanent intelligence creating new relationships between the user, the built and its ecosphere. From the simulation of megacities to the solid modelling of material systems, design has the potential to be informed by the real.
