The city wanted to take advantage of the renewal of the building envelope, which was to be carried out using movable scaffolding, in order to share equipment and renovate the obsolete and energy-consuming lighting while at the same time reducing costs.

Seen from various broad panoramas, the north, south and east facades of the Book Silo provide a very clear affirmation of the architectural identity of Lyon Municipal Library within the Part Dieu district.

At night, the lighting design by Guillaume Jéol, Roland Jéol Studio and BC Ingénierie emphasizes the overall volume and the perfect 17-floor rectangular parallelepiped clad in dark faience and the strong architectural lines of this heritage landmark by Perrin-Fayole. It also expresses the library’s function and supports its evolution toward a digital world based on the rapid, IT-enabled communication of messages and knowledge.
