Justine Emard is a visual artist. Her installations use AI to understand the living, exploring the boundaries between organic life and artificial intelligence. Bee swarms, encephalographic recordings and prehistoric paintings become learning supports for algorithms that, contrary to dystopian imaginations, generate new supra-hyper-organisms.
“ What will Paris be like under 50°C? How can we postpone this scenario and be better prepared for it? ”

Our dense, mineral-rich capital is ill-suited to the extreme heat we’ll increasingly have to cope with. So what adaptation strategies can we implement? This is what we asked to Alexandre Florentin, Paris councillor responsible for resilience and climate issues. He chaired the “Paris at 50 degrees” mission, which delivered its report a few months ago: what fields of action for architects and urban designers?
Périg Pitrou is an anthropologist at the CNRS and head of the “Anthropology of Life” team at the Collège de France. He is Scientific Director of the City-Metabolism Chair, which brings together PCA-STREAM and PSL University (Paris Sciences et Lettres). The aim: to identify how interdisciplinary collaborations can help overcome the challenges of building the urban worlds of the future.
Diego Landivar is a lecturer and researcher in economics and the founder of the Origens Media Lab, a “third place” research lab developed to address critical situations. More flexible and responsive than conventional research laboratories, Origens focuses on the far-reaching transformations brought about by the environmental crisis and supports civil society in its struggles.
Jean-Baptiste Fressoz is a historian of science, technology, and the environment. He contributed to popularizing the concept of the Anthropocene in France with his book The Shock of the Anthropocene, which he co-wrote with Christophe Bonneuil. With Les Révoltes du ciel [The Revolts of the Sky], co-written with Fabien Locher, he traces the history of our relations to climate change to put into perspective our contemporary vision of environmental issues.
The use of the living organism metaphor in the field of urban system studies dates far back and is continuously reconfigured as events play out. Here, Léone-Alix Mazaud, a CIFRE PhD student (PCA-STREAM/École des Mines de Paris), repositions the meaning of the “urban metabolism” as defined by our firm within the history of approaches on the subject matter in order to highlight its unique features.
Artists are major protagonists of the way our representations and narratives change over time, through image as well as fiction, which Frédérique Aït-Touati views as playing a fundamental role in the advancement of sciences and the construction of a collective imaginary. She is thus engaged, through her alternative cartographies and theatrical performances, in “landing” the gaze we turn towards the earth in order to highlight our belonging to Gaia. Besides her research on the developments of our ontological representations, she promotes, through SPEAP program, a pedagogy of experience, multidisciplinarity, and the dialogue between art and science.
The challenge of the Anthropocene must be addressed through cities, not only because they cluster challenges, but also because, according to Michel Lussault, their desirability will not decline in spite of various crises. The urbanity specific to the “relational city” remains crucial as an experience of otherness, and, in that respect, going full digital or generalized teleworking would represent a “counter-social” development. The increasing complexity of our global urbanization reinforces the systemic inscription of cities and drives urbanism towards ever-increasing levels of cross-disciplinarity, an approach he promotes at the École Urbaine de Lyon, in particular around the “common health” concept, intended to spatially approach issues of social justice, public healthcare, and ecosystem restoration.
The Anthropocene invites us to move beyond the idea of progress, universalism, and the logic of separation or domination of the modern project. It results in a fundamental change in the paradigm of contemporary art, especially around ecofeminist practices, which Tara Londi views as stemming from the feminist avant-garde of the 1960s and 1970s. The critique of the capitalist exploitation of nature, therefore, ties in with that of the patriarchal oppression of women in ecofeminist artistic practices, revealing the unspoken history of women, Indigenous peoples, or animals. Beyond the rationalism of the visual realm and of language, archaic animist and holistic visions are revived.
As part of the documentary “PCA-STREAM: From research to action”, we interviewed Jean-Louis Cohen, architect, historian of Architecture and professor at the Collège de France. He depicts a profession that is concerned about its place in the world today, and describes how architects are reinventing themselves in order to face the social, technical and environmental challenges of the 21st century.
Episode 3/5 of the documentary “PCA-STREAM, from research to action” examines the question raised by STREAM 03 on the links between urbanization and preservation of natural resources in the so-called Anthropocene era, in which Man has become the dominant transformation force of the biosphere. How can we sustainably live on a finite planet? Based on a cradle-to-cradle dynamic, the Stream Building offers a concrete vision of what a metabolic building can be, producing and reusing its own resources. – In the documentary “PCA-STREAM, from research to action”, filmmaker Gilles Coudert takes his author’s perspective, a specialist in contemporary art and architecture, on the link between research and action at the heart of the practice of PCA-STREAM agency. He gives the floor to an international panel of researchers, creators and professionals associated with the work of the agency: philosophers, art critics, artists, investors, policy makers, users, etc. Three architectural projects, realized or in progress, are taken as case studies to illustrate the conditioning of the architectural form by this collaborative exploration approach: #cloud.paris (with SFL), the Stream Building (winner of the competition « Réinventer Paris » , with Eurosic) and Shake (Euralille, with Nacarat). Those projects embody the way in which a metabolic, open and innovative vision of the city takes shape through the exchange and creation of new synergies between actors and visions to move from urban utopia to concrete realization.

Episode 2/5 of the documentary “PCA-STREAM, from research to action” traces the researches carried out for STREAM 02 on new work modes and workspaces. From the subprime mortgage crisis to the new liquid form taken by work, which irremediably blurs the line between work life and private life, this episode concludes with the project #cloud, result of cross-reflection on knowledge capitalism and users’ new expectations about comfort. – In the documentary “PCA-STREAM, from research to action”, filmmaker Gilles Coudert takes his author’s perspective, a specialist in contemporary art and architecture, on the link between research and action at the heart of the practice of PCA-STREAM agency.

Episode 5/5, epilogue of the documentary “PCA-STREAM, from research to action”, gives the floor to the various speakers in order to open, in their respective disciplinary fields, the scope of research and foresight. As a reflection laboratory, STREAM aims at questioning our tools and working methods in order to respond to a changing world and to live in it in a contextual and sustainable way while reinventing the profession of architect. – In the documentary “PCA-STREAM, from research to action”, filmmaker Gilles Coudert takes his author’s perspective, a specialist in contemporary art and architecture, on the link between research and action at the heart of the practice of PCA-STREAM agency.

The episode 4/5 of the documentary “PCA-STREAM, from research to action” outlines the subject of STREAM 04 (which will be published at the end of 2017). This new issue explores the repercussions of the Anthropocene era. It proposes to consider a new paradigm for the living, seen as a continuum, to overcome the existing divisions between nature and culture, object and subject, living and non-living. The Shake building in Lille, on which a part of the neighboring park winds up and continues, is a concrete example of this new cycle of study. – In the documentary “PCA-STREAM, from research to action”, filmmaker Gilles Coudert takes his author’s perspective, a specialist in contemporary art and architecture, on the link between research and action at the heart of the practice of PCA-STREAM agency.

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.
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.
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.
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.
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.
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.
