Theoretical experiments around the concept of the “metabolic-city” place living organisms at the heart of a new paradigm, encouraging a systemic approach. In urban and architectural practice, what tools are available to measure metabolism? Pauline Detavernier, Doctor in Architecture and Research and Development Project Manager at PCA-STREAM, examines existing measures of the life cycle and urban metabolism to outline a methodology.
“ What science fiction does to the city. ”
“ What science fiction does to the city. ”
Space is one of the great imaginary worlds of science fiction. By often depicting dystopian cities, authors sketch the contours of a desirable urbanity. Using science fiction as a field of investigation, Pierre-Antoine Marti, a PhD candidate in history at EHESS (School of Advanced Studies in Social Sciences), uses representations of the future as a dataset for prospective reflection on the interplay between science fiction and innovation.
We have never collected so much data in cities. The public space is thus subjected to a real “dataification”. But how can we explain this massive capture? What is it about? And what does it tell us about our time? An inaugural lecture by Olivier Aïm, lecturer at Sorbonne University and author of Les Théories de la Surveillance, followed by an afterwork co-organized with Yourban, The Swarm Initative and The Good AI.
Périg Pitrou is an anthropologist, CNRS Research Director at the Maison Française d’Oxford and head of the “Anthropology of Life” team at the Collège de France. He is Scientific Director of the City-Metabolism Chair, which links the agency with PSL University (Paris Sciences et Lettres). The aim: to identify how interdisciplinary collaborations can help overcome the challenges of building future urban worlds.
Landscape is not just a matter of shapes and colors. It also emanates from the sensitive perception of a sound environment, however urbanized it may be. This is what Sara el Samman defends in her diploma project, awarded by the Fédération Française du Paysage. Would La Défense be the same without the sound of heels on flagstones?
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.
Stéphane Lemoine is an architect and urban planner. He recently published the book Mix Urbains, which questions the nature of urban travel. By analyzing flows at eight intersections around the world, he studies speeds, rhythms, interactions and trajectories to determine what makes these urban squares special.
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.
Claire Doussard is an urban planner and researcher in the field of urban development. She focuses on measuring urban metabolisms and comparing various types of urban fabric in order to define the most environmentally friendly forms and ways of operating. Reviews and perspectives that face a great difficulty: data collection!
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.
These days we are generating a lot of data simply by carrying our phones around and consenting cookies on websites. While some of the data collected can be accessed by researchers for social good, other data is being used to provide targeted advertisements. Companies buy and sell our data, what is currently lacking is a mechanism for individuals to get a grasp of where their personal data is being used and for what purpose. An article by Saulė Gabrielė, Nadia Leonova and Lukas Utzig, Urban AI’s Emerging Leaders. Discover the extended version, Who owns your 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.
The notion of urban metabolism can be viewed in several ways. From a quantitative perspective, by considering flows; from a political ecology perspective, by considering social factors; and from an urban design perspective, by considering the sum of intertwined environmental and social ecosystems beyond administrative borders. In each of these approaches, urban technologies and the availability of data provide exciting prospects. To read the extended version : Do cities metabolize?
Jérôme Denis is a research professor at the Center for the Sociology of Innovation at Mines ParisTech. He examines the invisible work required by data processing (including in urban contexts), as well as on an approach to maintenance grounded in care. The focus afforded to material fragility, far from stabilizing the condition of objects, becomes inextricably involved in their future.
What we are currently calling AI has, in fact, very little to do with intelligence, although it does indeed make use of tremendous memory capabilities and computing power. The leading figure of French robotics, Bruno Maisonnier, is engaged in the challenge of developing an AI operating like a brain, using very little energy and data, while also being capable of justifying decisions. Would this be an AI with self-learning capabilities?
The trend towards smart cities reintroduces a functionalist vision of the city, generating ever-increasing amounts of data. But how can the parts of urbanity that cannot be reduced to quantified data to be optimized be considered? Larissa Fassler seeks to make visible what forms the urban experience through sensitive mapping that reveals an overlooked city.
In this interview filmed at the AIA Architecture Centre in New York, Michael Speaks, Dean of the School of Architecture of Syracuse, talks about the Design Energy Futures program that focuses on low-carbon planning and products. It aims to analyse datas in order to conceive scenarios of plausible futures and thus offer a better planification for urban expansion.

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.

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.
