The 21st century marks the beginning of a new era in human history : the anthropocene. The sum of our activities is now upsetting the geophysical balance of our planet. Urbanization is increasing exponentially. At the same time, alarm bells are ringing the world over, calling upon us to reduce our environmental footprint, preserve our natural resources, and protect biodiversity.

We must urgently reinvent the way we live in our homes, construct our buildings, and move around, as well as shift towards cleaner energy sources. Such a complex challenge must marshal every single field of human knowledge. PCA-STREAM investigates the work of researchers, thinkers, and creators in order to invent new ways of making the city.

Our firm is a creative and open ecosystem and this cross-disciplinary research informs our design processes. Together, we imagine ways to respond to these changing lifestyles and working patterns in order to anticipate the architecture and the city of tomorrow.

Podcast transcription: Raphaëlle Guidée

Raphaëlle Guidée is a specialist in narrative representations of economic, environmental and societal collapse. For over 10 years, she has analyzed the narratives surrounding Detroit’s bankruptcy in order to understand how an apparent ruin of capitalism can inspire discourses of domination or resistance. In La ville d’après : Détroit, une enquête narrative [The Aftermath City: Detroit, a narrative investigation] (Flammarion), rather than focusing on fictions, she seeks out testimonies and concrete stories, believing that modern times don’t need new narratives. We simply need alternative narratives. Read the transcription of her podcast below.

Beautiful like an encounter on the glass roof of colored clouds

For Daniel Buren, architecture is an open-air studio. In an exclusive interview with architect Philippe Chiambaretta, he talks about his site-specific work, where art and architecture meet, just like the Nuages Colorés that cover the scales of the 175 Haussmann glass roof.

“ My research question was: How do tools for integrating biodiversity into urban and architectural projects contribute to shaping multi-species urban worlds? ”

“ My research question was: How do tools for integrating biodiversity into urban and architectural projects contribute to shaping multi-species urban worlds? ”

Translating biodiversity

In this first episode, Léone revisits the genesis of her research topic and traces the evolution of her methodology. She adopts a “material semiotics” approach, focused on how biodiversity tools translate and make ecological knowledge perceptible. These tools are analyzed as “cosmograms,” according to John Tresch’s concept: objects designed to summarize the order of the world by materially organizing the relationships between humans and non-humans. But an examination of the diversity of these tools quickly reveals the difficulty in producing shared representations of biodiversity. This heterogeneity opens an investigation into the often implicit ways in which these tools shape our thinking and conceptions of the multi-species city.   Working with diversity: Operators sensitive to non-human life in urban and architectural projects In this series of four podcasts, we invite you to delve into the work of Léone, a researcher at the agency, who recently defended her CIFRE PhD thesis in Science and Technology Studies, supervised by Jérôme Denis at the Centre for the Sociology of Innovation (École des Mines, Université PSL). A series presented by Léone-Alix Mazaud and Jasmine Léonardon. Editing: Théa Lingrand.

“ Artificial intelligence is revolutionizing our relation to history, giving us access to previously indecipherable archives. ”

Using AI to tell history

On February 10 and 11, France hosted the Summit for Action on Artificial Intelligence, bringing together international companies and heads of state to identify the potential and limits (notably environmental) of this tool. This is an opportunity for us to discuss the subject of generative AI with Raphaël Doan, a specialist in the sciences of Antiquity and author of the uchronia Si Rome n’avait pas chuté (If Rome hadn’t fallen), an essay imagining, with the help of AI, what might have happened if the Industrial Revolution had taken place under the Roman Empire. Through this experiment, fascinating possibilities for historical and archaeological research are outlined, as AI facilitates the processing of archives, the translation of lost languages and the deciphering of burnt texts.

Podcast transcript: urban metabolism, at the heart of the matter

In urban planning and geography, the concept of metabolism is frequently discussed. This organicist metaphor likens a territory to a body, traversed by flows of materials and energy that link it to its environment. From a quantitative perspective, these flows can be measured over time and space to assess what a territory consumes, processes, and produces. However, a qualitative approach is equally crucial, examining the political and social trade-offs that shape urban metabolisms. With this in mind, we spoke with two researchers, Clément Dillenseger and Pierre Desvaux, who have explored the waste sector to analyze the socio-technical infrastructures that underpin metabolism and the imaginaries that shape its perception.

The potential of the night

Once a sanctuary for dreams and imagination, nighttime has now been relegated to the mere role of a utilitarian prelude to daytime. Nocturnal realms possess an alchemical power capable of transfiguring our perceptions. However, when viewed through the lens of urban uses, the night also exacerbates inequalities and raises questions about the possibility of achieving an urban night that is accessible to everyone. Exploring the range of possibilities associated with the night reveals it as a space-time where complex interactions are woven that could be revitalized through a chronotopic and inclusive architecture.

Capturing the Cityscape Through Photography

Capturing the Cityscape Through Photography

Over the span of several months, students from GOBELINS Paris scouted La Défense, examining the iconic business district from the fresh perspective of urban metabolism. As part of a documentary workshop led by Pierre-Jérôme Jehel and Laetitia Guillemin (GOBELINS) and designed in partnership with researchers from the City-Metabolism Chair at PSL University, some thirty students explored this territory. They did so by treating it not as a mere backdrop but as a living organism, traversed by flows, tensions, and rhythms, using photography as a tool for revelation. Their projects, located at the crossroads of artistic creation and research, unveil an alternative reading of this mineral space, between invisible flows and underlying tensions. Both sensitive and rigorous, this inquiry is chronicled here by Corinne Feïss Jehel (EPHE-PSL), Pierre-Jérôme Jehel, and Émilie d’Orgeix (EPHE-PSL) as part of a research project conducted by the City-Metabolism Chair (which is financially supported by PCA-STREAM, Artelia, and Groupama Immobilier).

Educating Citizen Architects: for a meaningful architecture

Andrew Freear runs the Rural Studio program at Auburn School of Architecture (USA). He believes that schools of architecture have an ethical responsibility to train citizen architects who are locally committed to concrete projects and experientially connected to contexts and places. To design an inclusive city, the Studio adopts an experimental field approach, combining analysis of the territory’s endemic problems, understanding of residents’ needs and new construction techniques.
