With Ivry Confluences, located in a changing urban landscape featuring brownfield sites and eco-districts, PCA-STREAM is designing a symbol of the revitalization of the south end of Ivry-sur-Seine. In dialogue with the local industrial heritage, the studio reinterprets the morphology of railway halls to develop a new complex with exacting environmental standards. An exemplar of next-generation offices, Ivry Confluences takes an active part in adding to the vibrancy and diversity of the district thanks to its active base and an extensive garden that opens onto the city.
Reuse
32-34 Marbeuf — Interiors
Discover
PCA-STREAM reinterprets Marbeuf, an emblematic Citroën garage from the 1930s, disfigured by successive transformations. The aim is to give it a new image and new uses by reinterpreting its original style, from its structure to the details of its fittings, translated by its interior design team.
Is the city going round in circles?
Léonie Debrabandère is the Director of the WAAO, Lille’s architecture center, and curator of the exhibition “La ville tourne en rond?” How can we get away from anthropocentric, productivist logics and create a city that self-regulates, regenerates and recycles itself? The exhibition takes us on a semantic and tangible exploration of the circular city, allowing anyone to implement re-usable solutions on all scales.
Sustainable Materialities in Construction
In France, the construction sector accounts for one third of the country’s CO2 emissions. Materials, which are partly responsible for this ratio, are extracted, transported, processed, poured or placed, dumped or incinerated… All these steps are opportunities to work on limiting impacts, involving architects, among other things, in deploying a new aesthetic.
Maximizing reuse, minimizing transformation
Maximum is a design studio that maximizes the value of waste; its material, its form and its engineering. Some materials are transformed in a semi-industrial process while others give birth to unique pieces, such as the glass walls of the Centre Pompidou caterpillar.
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.
