This lecture delves into the analysis of the early EPFL buildings, discussing issues such as circulation problems, orientation difficulties, lack of central conviviality, and technical challenges related to building design and energy efficiency. The instructor, Sébastien Oesch, provides insights into the evolution of the campus, addressing user critiques, the development of a central esplanade, improvements in circulation and orientation, and the gradual acceptance of on-site housing to alleviate transportation issues.
