Abstract
Following on from the previous paper, this presentation will focus on a field that has been present since the earliest days of architectural research, echoing the pioneering awareness of the fragility of living environments and the depletion of natural resources. The permanence of the theme, as well as the changes in its content, will be highlighted. It is intensifying in the powerful current of mutations and transitions of the moment. At the crossroads of the societal, the technological and the sensitive, it calls for the discovery of new projectual instruments and modalities. A few examples of research in this field will illustrate the point.
