Vers une pratique du réemploi en architecture : Expérimentations, outils, approches

Abstract : The world of construction is nowadays confronted with the requirements and challenges of the socio-ecological transition. The discipline of architecture is evolving in order to move towards a more eco-responsible architecture from a technical, cultural, economic and legal point of view. Reuse, less developed than recycling, is a practice that is emancipating itself at high speed and struggling to fit into the standardized production system attributed by the current industrial and socio-technical system. This thesis is part of the theoretical framework of the socio-ecological transition, which proposes a broader vision of the paradigm changes to be made by integrating, beyond the technical side (energy), all social actions and so-called ecological behaviours. In this sense, we situate our research within the theoretical framework proposed by Sylvain Lavelle , who opts for "a fairer transition" . He defends a polymorphic transition based on a change of oïkos, tekhnè, ethos and muthos, thus going beyond the energy question and integrating principles of social justice, relationship to the environment, ethics and new socio-cultural narratives. An action program can be transposed to the practice of reuse and more generally to the architectural discipline. This thesis questions the potential of this practice to induce other approaches and project tools to move towards a truly eco-responsible architecture. We propose the definition of oïko-responsible to support the need for a change of perspective in light of this term, and to give a reading of the programme of actions it implies. Although philosophical, these definitions have served as a framework for reading and analysing experimental practices and tools for a dual corpus of operational (eight actors) and pedagogical (one module) practices; they have also enabled us to explore the basis for commitment and meaning of this practice. The challenges of this work consist in taking stock of this emerging practice and looking at how it guides the triple practice of architecture (pedagogy, research, operational). It will then be necessary to verify the hypothesis that reuse can induce an oïkos-responsible architecture by mobilizing the triple activity of operational practice, pedagogy and research. To this end, we propose a first step demonstrating how practitioners work towards the professionalization of reuse by reintegrating experimental dynamics into the project process. Secondly, they demonstrate their ability to redefine or create tools for reuse that can respond to this eco-responsible change. These two phases draw a portrait of actors who ultimately request this practice of reuse as a tool to requestion the ethics of architectural practices.
