The first session of the conference mainly started with the topics on existing built infrastructures and revitalization projects was moderated by Alexander stumm and Christian Gäth. One of the projects with this focus, the sustainable transformation living lab in Aachen presented a very analytical approach based on observation concerning climate change and key question of how to integrate the users in the process of conceiving the project. They also addressed the need to develop the ideas with a special focus on the living lab and climate labs as summer school. Another Key approach was presented in the project of RE:chenzentrum Minimal maximal where the inhabitants of the project were introduced directly on the design table to develop possibilities and produce ideas together as a participatory process.

The second session focused on Material flows and chains was moderated by Elke Beyer. The project Re. material – an open studio for circular building in this session engaged itself as a student initiative in a real context, discussed the challenges and experience of interaction with people and experts on the topic. The second project Material matters explored the aspects of material recyclability, awareness about the subject and potential for shared knowledge resources on the same. Third paper discussed the preconception and repression of earthen Architecture in Europe and the need for mapping the cultural heritage in the German context and learn from it. A rather practical methodology was brought by another paper, where the material testing was in central focus as potential building material for indoor and outdoor climate in the same session.

Design and Process - Reduce, Reuse, Recycle.The third session presented the projects with a focus on design approaches, concrete examples and realized projects. The session presentation therefore took place with the formats of Poster, Prototypes, Models and videos in the exhibition space. This session included 1:1 scale prototype as well as student lead & executed thesis projects. The project of architecture as a living ecosystem shifted the focus from design to research and brought in the idea of values as guidelines for the design process in focus. With a Focus on constructive design intervention, the session brought in potential guidelines, design build formats along with experimental prototypes for sustainable building in the future.
