The Champs‑Élysées, History & Perspectives exhibition presents the study conducted between 2018 and 2020 at the behest of the Comité Champs‑Élysées by PCA-STREAM in collaboration with some fifty researchers, historians, scientists, engineers, artists, and economic and cultural actors from France and abroad. It traces the development of “the most beautiful avenue in the world,” analyzes its current usages, and proposes a vision of its potential evolutions in response to the challenges this area of the city faces in the present day. The Champs-Élysées is becoming a collective space to experiment with the development of a sustainable, desirable and inclusive city by 2030 through focusing on four main strategic priorities: reducing the impact of urban mobilities, rethinking nature as an ecosystem, seeking new uses, and the use of data for measurement and regulation.
Ecosystems

“ Capturing the conflict between the songs of nature and urban noise. ”
The melody of the living
Frédéric Jiguet is an ornithologist and professor at the Muséum d’Histoire Naturelle in Paris. In particular, he leads the STOC program: Suivi Temporel des Oiseaux Communs (Temporal Monitoring of Common Birds), which aims to understand the impacts of global change and the consequences of human activities on birds. We met him in situ, capturing the conflict between nature’s songs and urban noise.
Vulnerability as an inclusive principle
Emma Vilarem has a PhD in cognitive neuroscience, specialising in the study of social interactions. Co-founder of [S]CITY, she helps city planners integrate the psychological, emotional and social needs of residents into their projects. If the urban environment affects our brains and behaviors, couldn’t paying attention to the most vulnerable inhabitants improve the overall experience of the city?
Applying a research approach in an architectural practice
Etienne Riot, urban planning researcher, and Pauline Detavernier, architecture researcher, are at the heart of applied research and innovation at PCA-STREAM. Together, they talk about the different facets of this research, from a CIFRE contract, to the setting up of a university chair project, to the subjects explored by the collaborators.
Defining the "Metabolic City"
Léone-Alix Mazaud, a CIFRE doctoral student (PCA-STREAM / École des Mines), here repositioned our definition of the “metabolic city” within a history of approaches to urban “metabolism”; a long-standing metaphor used in the study of urban systems, yet one that has been reconfigured over time.
PCA-STREAM takes its inspiration from its research on new workspaces, which are gathered in the second issue of the Stream book-magazine, “After Office,” in order to design its premises in the Marais, on the site of a former printing house. Designed as an ecosystem that brings together a variety of spaces for the use of a large multidisciplinary team, this place is the spatial embodiment of PCA-STREAM as well as a manifesto of its innovative vision of the work space.
As part of the Eurodisney development zone, PCA-STREAM is designing a mixed-use, open-plan tertiary campus, co-designed with its user, Crédit Agricole Brie-Picardie. It embodies the traditional values of this bank, its environmental, social and cultural commitments, but also its commitment to the uses of tomorrow.

Conceiving the urban environment as an ecosystem
Biomimicry consists in reproducing not the forms but the functions of nature. On a neighborhood’s scale, it involves drawing inspiration from an ecosystem’s dynamics, which Eduardo Blanco, environmental engineer, calls “regenerative urban projects.” But how can we evaluate the effectiveness of this design method and how can we measure its success over time?

The gardener's intelligence
Gilles Clément coined the concept of the ‘planetary garden’ which invites everyone to take care of the Earth as they would a garden. Having all too often been confronted with the sheer ignorance of how ecosystems and the living world operate, he, therefore, proposes creating a Ministry of Knowledge to lift us out of the ‘Stupidocene.’ Read transcript A PCA-STREAM production Coordination: Jasmine Léonardon Editing: Mattéo Caranta Music: Alexandre Desplat
Talking Data
Caroline Goulard is a data journalist and co-founder of Dataveyes. She turns collected data into digital experiences to make it more understandable for everyone. Thanks to new ways of visualization, it is now possible to understand a population’s needs and to develop services that anticipate new uses.
AI doesn’t replace architects but supports them
Researcher and data scientist Stanislas Chaillou investigates how AI can enable architects to support and enhance their practice. A small sampler of a new book published by Éditions du Moniteur in March 2021.
Co-creating a learning society
François Taddei is a geneticist and co-founder, with Ariel Lindner, of the Learning Planet Institute (formerly known as CRI). Conceived as a school for the 21st century, the institute combines artificial intelligence and collective intelligence to reinvent ways of learning, teaching and doing research.
AI facing complex urban environments
Hubert Beroche is the founder of the Urban AI think tank, dedicated to the field of urban artificial intelligence. He is the curator of the Eyes on the street lecture series, run together in partnership with the SCAI (Sorbonne Center for Artifical Intelligence), and explains here how urban AI can help us understand the city.
Complexity, multiplicity, and adapatation within ecosystems
Contemporary architectural research is often fascinated by biological life but with an approach that goes beyond simple organic metaphors thanks to recent technological developments. Alisa Andrasek discusses the link between biology and her architectural practice, and her interest in the distribution of information in natural processes—a complexity that she tries to approach via big data. Her work in computational design is influenced by the convergence between information and materials, in an increasingly complex and open synthesis which enables it to go beyond the production of form and address the dynamic processes of matter itself. Alisa Andrasek is an architect, director and founder of the Biothing laboratory. She teaches at the Architectural Association of London.
Modeling the City Using Proteins
Researcher Claire Lesieur works at the CNRS Ampère Laboratory on the Go Pro project, which applies a computational model developed for protein folding to urban environments. The shape-changing properties of proteins are put to use in an attempt to map out the opportunities for urban growth that don’t involve urban sprawl.
Demystifying and Repoliticizing Urban Data
In the face of the promises of the prophets of artificial intelligence and the marketing of those major economic players promoting the smart city as a solution to urban ills, Jérôme Denis and David Pontille remind us of the irreducible materiality and fragility of cities. Demystifying what they perceive as a form of “neopositivism” of data, they point out that data doesn’t exist per se, and in fact must be generated and then maintained at a significant cost. As a result, data is never neutral and takes on a fundamentally political dimension. Understanding this framework leads them to promote a paradigm of maintenance and fragility, instead of the more common one of sustainability and resilience, when approaching urban realities.
