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.

Exploring methodologies to understand the living city

Theoretical experiments around the concept of the “metabolic-city” place living organisms at the heart of a new paradigm, encouraging a systemic approach. In urban and architectural practice, what tools are available to measure metabolism? Pauline Detavernier, Doctor in Architecture and Research and Development Project Manager at PCA-STREAM, examines existing measures of the life cycle and urban metabolism to outline a methodology.

Applying a research approach in an architectural practice

Etienne Riot, urban planning researcher, and Pauline Detavernier, architecture researcher, are at the heart of applied research and innovation at PCA-STREAM. Together, they talk about the different facets of this research, from a CIFRE contract, to the setting up of a university chair project, to the subjects explored by the collaborators.

Defining the "Metabolic City"

Léone-Alix Mazaud, a CIFRE doctoral student (PCA-STREAM / École des Mines), here repositioned our definition of the “metabolic city” within a history of approaches to urban “metabolism”; a long-standing metaphor used in the study of urban systems, yet one that has been reconfigured over time.

The challenges of contemporary justice architecture

Courthouses constitute a complex program, part of an architectural, symbolic and political history that has yet to be fully explored[1]. A historical perspective, combined with an analysis of its contemporary issues, can nevertheless help us understand and question the tensions inherent to its architectural form.

Prospectives and Retrospectives of Office Developments

“The office is dead, long live the office!” Whether this is a fad or actual societal transformation, articles and reports are on the rise and continue to predict a disruption in office real estate. A review of 30 years of prospective and retrospective thinking questioning office real estate programs can provide us with the key to a better understanding of this phenomenon.

Is plastic getting a facelift?

The star of the stage of the recently concluded Design Week in Paris, plastic seems to have moved beyond the disdain it had been experiencing lately. Thanks to recycling, its environmental footprint is now better controlled, which has turned into a real selling point. But beyond the material itself, it is an entire production logic that should be “recycled” to extricate ourselves from the dogma of newness and disposability.

At the roots of “Urban Metabolism”

The use of the living organism metaphor in the field of urban system studies dates far back and is continuously reconfigured as events play out. Here, Léone-Alix Mazaud, a CIFRE PhD student (PCA-STREAM/École des Mines de Paris), repositions the meaning of the “urban metabolism” as defined by our firm within the history of approaches on the subject matter in order to highlight its unique features.

Does the company cafeteria still have a future?

From virtual canteens to connected fridges, a whole range of innovations is gradually being introduced in office buildings. They are part of a fundamental movement that is shaking up our lunchtime practices. It’s no longer just a question of space, but now also of experience. As is often the case, these innovations are provoking change as much as they are responding to our changing needs. Will the company restaurant be able to respond?

How to reconcile plantations and constructions in cities

Space, earth, water, and time. These are the key ingredients for an intelligent conditioning of plants in our cities. They are also what is sorely lacking in our cities. What good habits should be followed to reconcile plantations and urban constructions and what knowledge must we develop?

The challenges of timber construction in addressing the climate emergency

The construction sector accounts for one third of France’s CO₂ emissions. This environmental footprint can be reduced by using wood, but wood only stores carbon temporarily. The challenge of sustainable construction therefore lies in a comprehensive approach that includes forest management and the durability of buildings. No ‘woodwashing’ here, but some thoughts on mixed construction!

Care & repair for the urban future

In the current climate of instability, new ways of thinking and acting are being considered. Among them are two attitudes of care for the living and the non-living. The planning of cities and territories is the privileged field of application of these concepts, symbols of a profound reconfiguration of our relationship to the world.

Designing a façade like a membrane

How can a building’s energy balance be maintained as a living organism would? The search for solutions has come to the forefront of contemporary concerns, with a view to finding a way for architecture to self-regulate its energy consumption based on uses and the fluctuations of the environment. One of the first surfaces concerned is the building’s façade, which is very similar to the material envelope of a body or the membrane of a cell: an interface between an interior that must be kept in balance and an exterior that is subject to variations the interior must be protected from. Much is at stake in the case of high-rise buildings. The double-tower high-rise “The Link,” which will emerge in La Défense in 2025, is typically subject to various constraints and challenges. To optimize user comfort, an ideal balance must be found between two paradoxical factors: the importance of daylighting and protection against exterior heat.
