I would like to start with an expression: " sharing ambiances ". There are at least two meanings underlying such an expression. On the one hand, we can question whether it is possible to share ambiances and ask ourselves whether an ambiance can always be shared, whether certain conditions must be met for an ambiance to be shared, whether what is " shareable " takes on a particular expression when it is viewed through the lens of ambiances… These are what we can call " experienced ambiances " , ambiances as they are experienced by the senses. But we can also share conceptions about the idea of ambiances and test the extent to which it is possible to agree on the notion of ambiance, initiate a debate on the meaning and contribution of such a concept, experiment with types of dialogue between different disciplinary fields, etc. We can call these: "reflective ambiances" , i.e., ambiances as they are addressed by thought.
