A low-carbon structure relying largely on the use of wood in the heart of Paris: Temporary cover of the Chatelet-Les-Halles interchange station entrance, located at Place Marguerite de Navarre in Paris.

Mixed timber and steel structure deliberately designed using the principles of a very low-carbon construction.

Subtle engravings, an anamorphosis created by partial digital-cut, act as a visual signal.

« Carbon neutrality is not an unattainable dream
Embracing the revolution taking place after the Paris Agreement (COP21), we want to demonstrate, as the designers of this structure, that building projects can be places designated for storing atmospheric carbon, through the use of wood in particular.
Performing well both thermally and structurally, wood is a bio-based material which has the unique property of being a real carbon-store! This makes it the top candidate to promote and to ensure carbon reduction during the construction process.
For this temporary cover project, which constitutes mainly construction in wood, the figures speak for themselves! :
• Net emissions ~17t CO2eq
• Carbon stored in the structure ~27t CO2eq
This is the assessment of the greenhouse gas emissions related to the fabrication and construction of this project.
As well as its natural durability when the project is decommissioned and deconstructed the different elements making up the structure will, we hope, benefit from a second life in a new project and continue to store carbon in the wooden elements, for as long as possible. This project exemplifies our principles of zero-carbon architecture and a circular economy, where the reuse of materials is prevalent! »
