This theme explores new tools, methods, and technologies for project design. It also deals with the use and understanding of mass data, whether through the identification of data sources or their use via artificial intelligence algorithms.
Through animation, installation, sculpture and painting, Victor Cord’homme reveals the complexity and tireless workings of an urban system over which humans are losing control. He works on the autonomy of his installations and exhibitions, whose behavior varies according to the audience, invited to interact yet powerless to do so.
The French underground and aerial landscape is made up of approximately 910,000 km of drinking water distribution pipes, and over 1.4 million km of power lines. Indispensable in our daily lives, they are nonetheless invisible and increasingly questioned in the light of ecological and technological challenges that are transforming our territories. But can’t these infrastructures be seen as a heritage to be maintained and cared for?
In this round-table discussion, the four researchers look at the issue of transition through the prism of the different notions of maintenance, transformation, repair and restoration. These concepts are reminiscent of the issues of destruction, reconstruction and rehabilitation in architecture.
“ Sewers are the mirror image of what happens on the surface. ”
“ Sewers are the mirror image of what happens on the surface. ”
Did you know that we have a lot to learn from sewers? Sewers contain numerous chemical indicators that provide information about the practices of people living above ground, such as the use of medicines and drugs, diet and the state of intestinal flora. By focusing on the city of Paris, the EGOUTS (sewers) research project, funded by the French National Research Agency (ANR), is seeking to shed light on public policy ‘through the dark side of the City of Light’.
AI is a new form of intelligence whose development is stirring up concerns and dystopian fables. Far from replacing human intelligence, AIs are emerging as new tools to be trained, controlled and shaped to achieve the desired result. For the artist, photographer, architect, film-maker, musician or illustrator, AIs become an agent with which to collaborate, resulting in co-creation. Inaugural lecture of the “AI and Creation” series at the Stream Innovation Center.
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.

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.
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.
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!
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.

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?

University professor and PhD in Economics Lise Bourdeau Lepage has developed tools for measuring well-being that can be used to conduct territorial diagnoses. She shares this methodology in a guide for elected officials, with a view to helping public policies place humans and their well-being at the heart of planning and development. READ THE TRANSCRIPT
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.
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.
Artificial intelligence has taken center stage in forward-looking discourse on the city. In 2021, anticipating the advent of generative AIs, Bruno Maisonnier distinguishes between weak AI, which is less about intelligence than about computing power, and organic AI, developed on the model of the brain and social insects. Despite the risks inherent in the introduction of any new technology before its use has been regulated, Bruno Maisonnier offers an optimistic view of artificial intelligence, particularly with regard to the optimization of genetic engineering.
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?
Though AI is revolutionizing the practice of architecture, it follows the increasing digitalization that has been unfolding since the 1980s. Kent Larson was one of its pioneers. Alongside the City Science research group at MIT, he explores how data can help imagine production processes and innovative forms of urban governance stemming from an evidence-based approach and favoring consensus-building through modeling. He views this holistic approach to the complexity of urban reality as the only one that could bring about genuine change, though it raises the issue of the quality and control of data. He also calls for community databases offering an alternative to surveillance capitalism.
Artificial intelligence sparks as much enthusiasm as fear in its applications in the built and urban environment. Architect and data scientist Stanislas Chaillou puts this innovation into perspective by replacing in its technological timeline and demystifying the way it operates, which is in fact based on statistical learning. AI brings three major contributions to architects: assistance (for tedious chores), options (in the iterative design process), and the connection to context (by taking better account of local data). AI thus carries less of a risk of standardization than an opportunity to develop a style, to adapt to multiple contexts, and to vastly increase the capabilities of architects.
While the Anthropocene confronts us with our indissociable connection with Earth, for Refik Anadol we are living in an hybrid reality born out of the ubiquity of technological systems. He is engaged in the quest for a universal language to express this new era where the real and virtual worlds are intertwined, experimenting through prospective forms of representation which materialize data sets.
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.
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.
