Abstract EN:

The expression "ecological architecture" is an enigma. Apart from its impact on the media, these two words also hide some complex, ambiguous and often paradoxical issues. So what to do then with the relation between architecture and ecology ? To respond, the thesis undertakes critical analysis and while offering a historical perspective through nine cases studies. It offers to question the relationship between architecture and ecology, starting from the reflection initiated by Felix Guattari and his term ecosophy, which links together all three spheres of ecology (the environment, the social and the human subjectivity). Without it, one perceives only the techno-scientific perspective of the issue. But what is at stake here is in fact the occupation (indeed human) of the earth. The thesis follows the idea that the work of an architect can considered ecological only if the architect rethinks the question of tangible and intangible territories and the relations that form in between. It thus explores the way architects (re)create "worlds" by defining divisions between different space, times and also knowledge. The notion of "frontières" is thus proposed as the central key to understanding in these negotiations
