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.
Bioclimatic
Exotic trees in the City
Botanist Serge Muller, a professor emeritus at the French National Museum of Natural History, is a specialist of “invasive alien species.” He discusses the concept of “nativeness” and lays out the contours of a policy opening cities to new tree species that could become important allies in coping with global warming. Based on an interview conducted in partnership with Coloco.
Complexity, multiplicity, and adapatation within ecosystems
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.
Modeling the City Using Proteins
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.
AI Doesn’t Replace Architects But Supports Them
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.
The Time of Trees
The rediscovery of the ecosystems services of nature in urban environments, in particular regarding pollution mitigation and fighting against heat islands, have put a new emphasis on the intelligence of trees, as botanist Francis Hallé describes “plant architecture.” He advocates making trees more prominent in cities, though as a prerequisite to any urbanization, which implies promoting an intimate knowledge of the way they operate and their temporality in order to improve their planting, maintenance, and respect.
Stone
Discover the inaugural lecture of the “Alma Matter” series! In a world where the myth of abundance is collapsing, this series of lectures looks at what matter really has to offer. Actors, professions, economies, temporalities, geopolitics: how do contemporary issues of creation take shape through those of matter? Each talk focuses on a particular material, and brings together its stakeholders in a dialogue. The use of stone in construction declined during the twentieth century. Today, its return is acclaimed for its qualities: inertia, durability, low-emission processing, local presence… but what techniques and applications will be used in 2024? As part of the City Metabolism Chair supported by the Université Paris Sciences & Lettres.
Talking Data
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.
Co-creating a learning society
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.
AI facing complex urban environments
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.
