Show-casing material research results and reporting in journal form of first shared colloquium. The research exhibition “Prototypes” focuses on direct full scale testing of defined design criteria against real-world methods of realisation and production. The Innochain Network Journal #4 The Second Year Colloquium was hosted by IAAC, the Institute for Advanced Architecture of Catalonia, in Barcelona for the month of February 2018. The Institute for Advanced Architecture of Catalonia (IAAC) is a centre for research, education, production and outreach, with the mission of envisioning the future habitat of our society and building it in the present. Early Stage Research (ESR) Projects were presented at COAC, the Col-legi d’Arquitectes de Catalunya. The Catalan organization dates back 80 years of establishment in society as a benchmark for architecture, enjoying national and international collaborations. The Association’s mission is to uphold the social value of architecture and city planning on behalf of society as well as architects. Following the three day event of presentations and networking, the congruent exhibition of ‘Prototypes‘ was presented at the IAAC Atelier, P59. The three day event consisted of presentations and discussions with the ESRs and guest speakers, industry partners, collaborating institute leaders and a general audience, in accordance to the three research packages presented: Communicating Research, Simulation for Design, Materialising Design. ESRs shared their developement on their physical prototypes, simulations and the feedback loops between hardware and software. Industry Partners were interviewed about their perspective of working with PhD candidates on research development while simultaneously using their technologies in real world projects. How can this experimental method of development be mutually beneficial for both progressive companies while also working on the preparation of advanced students for the ‘real world’? Dialog between the ESRs, their research supervisors, the Industry Partners, as well as general audience has been transcribed for the purpose of presentation in this journal. Furthermore, this journal edition includes the experience of educational events that have taken place this year such as the Winter School, hosted by HENN Architects as well as the Summer School hosted by Smith Architects. Moving forward, the ESR’s will be recording their PhD findings in written format while preparing for the upcoming final exhibition in Copenhagen hosted by CITA, the Centre for Information Technology and Architecture.
