PB22 Towers : a silhouette shaped by the sun’s path

  • Publish On 2 May 2017

In the context of a revitalization of La Défense, PCA-STREAM has imagined a complex form that grows through morphogenesis. PCA-STREAM explored the idea of an innovative tower that is not limited to the endless extrusion of a standard floor: revealing complex, sensual and changing forms that depend on the position of the spectator and the light, the project deploys organically inspired forms according to a logic of “natural” growth. The general form and slenderness, quite similar to a plant, emerge from the twisting architecture and a progressive displacement of the levels.

The art of artificial life

Justine Emard is a visual artist. Her installations use AI to understand the living, exploring the boundaries between organic life and artificial intelligence. Bee swarms, encephalographic recordings and prehistoric paintings become learning supports for algorithms that, contrary to dystopian imaginations, generate new supra-hyper-organisms.

“ Sewers are the mirror image of what happens on the surface. ”


What sewers say about us

Did you know that we have a lot to learn from sewers? Sewers contain numerous chemical indicators that provide information about the practices of people living above ground, such as the use of medicines and drugs, diet and the state of intestinal flora. By focusing on the city of Paris, the EGOUTS (sewers) research project, funded by the French National Research Agency (ANR), is seeking to shed light on public policy ‘through the dark side of the City of Light’.

Artificial Intelligence in the creation process

AI is a new form of intelligence whose development is stirring up concerns and dystopian fables. Far from replacing human intelligence, AIs are emerging as new tools to be trained, controlled and shaped to achieve the desired result. For the artist, photographer, architect, film-maker, musician or illustrator, AIs become an agent with which to collaborate, resulting in co-creation. Inaugural lecture of the “AI and Creation” series at the Stream Innovation Center.

Wood

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?

"The network is alive" — Networks and those who maintain them

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?

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?

Rethinking the Campus: Balancing Tradition and Innovation

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.

Metal

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?
