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.

Aurélie Mossé is a designer, researcher and head of the Soft Matters research group at the Ecole des Arts Décoratifs. Using micro-organisms, she is experimenting with the manufacture of innovative materials that are less costly in terms of fossil fuels or non-renewable resources. By producing calcite, bacteria could become allies in the creation of solid building materials.
France has the 4th largest forest area in Europe, yet 40% of its timber is imported. At a time when Google’s London headquarters, designed in 2016 with a solid wood structure, has still not been delivered, and when the tallest wooden tower is due to be built in Tokyo in 2028, reaching a height of 100 metres, where does France stand in relation to wood? The RE2020, through the dynamic life cycle analysis, encourages the use of bio-sourced materials to promote the storage of biogenic carbon in buildings. The SNBC is explicitly banking on this sector to achieve its 2050 targets. However, the Paris Fire Brigade doctrine published in 2021 greatly complicates its use in architecture. How can these contradictions be overcome?
A symbol of the industrial revolution, the rise of metal in construction accompanied the renewal of Paris under Haussmann. Its origins in blast furnaces is associated with a high carbon footprint. Yet it is still widely used in facades, and seems promising for circular economy, as it is easy to dismantle. But is this enough of an advantage?

At its core, the campus embodies an enduring quest for an ideal. Its form is fraught with tensions inherited from a long history that remain relevant even as it adapts to contemporary challenges. Driven by a race to maximize their appeal, campuses are transforming into architectural showcases, competing with corporate headquarters in embodying new values and attracting top talent. Their structures and functions are evolving to meet the shifting needs of education and society. By embracing the archetypes of the agora and the garden—the original dichotomy of campuses—these bastions of knowledge are forming the contours of a new era in higher education.
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?
Although soil is used as a building material in many parts of the world, it has often been regarded as a waste product in France in recent decades, with little use being made of excavated soil. However, its thermal and hygrometric properties, its extremely low carbon footprint when used raw, its abundance and the natural variations in colour that it offers in every region make it a rich and inspiring material for today’s architects and designers. How can we adapt our building techniques to bring this material into line with contemporary requirements, and get rid of the vision of primitive housing that it still evokes for many people?
La Vie à l’œuvre (Life in the Making), a collective of researchers in the natural sciences, humanities and social sciences, as well as artists, was set up at the Université Paris Sciences & Lettres in 2014 to explore interdisciplinary collective intelligence around the theme of the living. Functioning as an incubator of ideas, they explore the potential of living beings, particularly via experiments between art and science. A Stream 05 – New Intelligences article to discover!
