The circular pavilion promotes anti-waste architecture

Posted on 09 December 2015.

Especially for COP21, the ephemeral architecture of the circular pavilion in Place de l'Hôtel de Ville in Paris demonstrates how to save resources.

Pavillon de l'Arsenal has built its circular – but not round - pavilion for COP21: an ephemeral building built with reused and recycled materials.

One of the major issues in the circular economy is preserving resources and raw materials - in particular construction materials. The Encore Heureux architect cooperative met this challenge by designing the circular pavilion in Place de l’Hôtel-de-Ville in Paris. This ephemeral building, erected during the lead up to COP21 by the Pavillon de l'Arsenal - the center for information, documentation and exhibition for urban planning and architecture in Paris and the Paris metropolitan area – experiments with architecture that reuses materials and recycles resources. A façade cladded with oak doors recovered from an old Parisian building, secondhand Rockwool insulation, exhibition panels for the floors, repaired and repainted furniture from the capital’s waste collection center, decommissioned urban lighting and even Paris-Plage duckboards have been used in the construction. It is open to the general public until 3 January and over the coming weeks will host a circular café, debates, conferences, meetings, workshops and anti-waste inspired performances. Great for educating the children – and their parents - performances will be held on weekends. A giant model building encourages the kids to think about the concept of ecological housing and living together.

Anti-waste in architecture

The Encore Heureux architect cooperative, created in 2001 by Nicola Delon and Julien Choppin, designed the circular pavilion. They were involved in an exhibition in 2014 called "Grey Matter", dedicated to recycling and reusing materials. The circular pavilion continues this process of reflection and is a reminder that both the intrinsic consumption of a building over time as well as the resources and energy that were needed for its construction are part of its carbon footprint. The circular pavilion is intended to demonstrate the circular economy: one person’s waste is someone else’s resource.
