The use of stone in construction declined during the 20th century. Today, its return is acclaimed for its qualities: inertia, durability, low-emission processing, local presence… with what techniques and applications in 2024? Introduction to the series by Elisabeth Bouchaud, materials physicist and playwright. With Cyril Pressacco, architect and co-founder of the Barrault Pressacco agency, Denis Macrez, artist, Ana Hedan, Director of Prescriptions at Rocamat and Paul Vergonjeanne, doctoral student in architecture.
In the heart of the revitalized Porte Maillot district, PCA-STREAM revisits the Parisian modernist heritage and extends the city-nature dialogue. The agency’s intervention respects and enhances the architectural qualities of the original structure. On the north side, the façade grid is reinterpreted in a contemporary style inspired by its original rigorous layout. Designed as a balcony overlooking the Bois de Boulogne, it highlights the exceptional linear nature of the building with unobstructed views of the greater Parisian panorama.The new headquarters of Murex, the world leader in software for the financial markets, was designed above all to maximize interaction and collective intelligence, an essential function of a head office that has been reinforced by the health crisis. Spaces are streamlined and legible, and fluid circulation is ensured by a core of elevators and Chambord staircases on the first day. Employees meet and exchange ideas in a place conducive to informal dialogue.
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.
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.
