Located in the heart of the agency, the Stream Innovation Center welcomes the community of urban specialists. Here, disciplines cross paths: arts, sciences, and society. We cultivate new methods, imagination, and knowledge. We share and disseminate through debates, conferences, screenings...
There are six axes for exploring urban issues:
— the architectural transition: bioclimatic design, low-carbon construction, and knowledge of materials
— living systems encompass research on biodiversity, the experience of nature, and nature-based solutions
— new Imaginaries is concerned with new forms of narrative and representation, particularly to accompany the emergence of a new post-Anthropocene aesthetic
— new uses explore ways of living, working, producing, learning, exchanging, moving, etc., in order to develop programmatic responses in projects
— data and design technology investigate the fields of digital transformation in the field of urban design at all scales
— the city-metabolism aims to understand the complex and integrate it into the design process, question the relationship between humans and the living, and take into account the multitude of necessary knowledge, for a holistic approach to urban issues in the face of environmental challenges.

During this roundtable, the four researchers will address the question of transition through the prism of different notions such as maintenance, transformation, repair and restoration. These concepts are not without evoking the issues of destruction/reconstruction/rehabilitation in architecture.

Eyes on the Street cycle
The Eyes on the Street cycle aims to explore and question the capture of urban data in public space.
What does it tell us about our time? What are its modalities? Can we escape it? To what extent does this data capture modify our "right to the city"?
A series of 6 events co-organized by PCA-STREAM, Urban AI and Sorbonne Center for Artificial Intelligence.
Moderator: Hubert Beroche
Scientific Director: Olivier Aïm
June 01, 2023 — 7pm - 8pm
The relationship between urban sensors and city dwellers is often unbalanced, between invisible capture and monopolization of information. To question how design can contribute to rebalance this relationship, we will scan devices for camouflaging individuals and revealing sensors in urban space.
A discussion between Geoffrey Dorne, designer, author of Hacker Citizens and Hacker Portester, Federica Busani, Cofounder of the tech-fashion startup Cap_able and Jonathan Pichot, European Director and Tech Lead at Helpful Places (born at Sidewalk Labs before becoming independent following the abandonment of the Toronto urban renewal project).
This conference will be followed by a fashion show featuring the anti-facial recognition collection, Manifesto — 8:00-8:30pm
With its colorful clothing resembling animal fur, Cap_able aims to invisibilize citizens against the misuse of biometric recognition cameras which, if neglected, could affect freedom of expression, association and free movement in public spaces.
The show will be followed by a cocktail party to conclude the Eyes on the Street cycle.

MOOC LAUNCH EVENT [BY INVITATION] — Building and Climate Change: What Mitigation Strategies?
The building sector generates 23% of greenhouse gas emissions and 43% of French annual energy consumption. It is a key sector for the ecological transition! In order to meet this challenge, this MOOC proposed by the Observatoire de l'Immobilier Durable (OID) and filmed at PCA-STREAM's proposes, in 5 2-hour sequences, to answer the following questions:
— How to make the right decisions at each stage of the building's life?
— What materials should be used for low-carbon construction or renovation?
— How to prioritize decarbonization actions at the scale of a building portfolio?
To be followed from 17/05/2023 to 20/06/2023 with a teaching team composed of members of the IDO and Guillaume Mangeot, Agency Director and Laélia Vaulot, Environmental Strategy Manager for PCA-STREAM.
March 06-10, 2023 - PSL WEEK
Living cities: designing, building and inhabiting the urban worlds of the future
In partnership with the PSL university group, the "Anthropology of Life" team, the Social Anthropology Laboratory and PCA-STREAM, an interdisciplinary training week has been organized to better understand how the functioning of living beings, both human and non-human, influences the organization and development of cities. The objective is to identify how challenges for the design and construction of future urban worlds could be overcome through interdisciplinary collaborations of urban planning and architecture with natural sciences, engineering sciences and humanities and social sciences.
April 20, 2023 — 7pm - 8pm
Sensors are mainly thought, designed and deployed as tools for over-surveillance. However, as Anders Albrechtslund's experiments have shown, these technologies can be used for care, sociability and under-surveillance. Meet one of the pioneers of surveillance studies!
A conference - in English - at the SCAI (Sorbonne Center for Artificial Intelligence) by Anders Albrechtslund, professor in information sciences at the University of Aarhus (Denmark) and director of the Center for Surveillance Studies.
Address : 1st floor, Esclangon Building, Campus Pierre et Marie Curie, 4 place Jussieu, 75005 PARIS
April 11, 2023 — 7pm - 8pm
We often imagine technological devices when it comes to urban capture. But capturing is also about listening, observing, touching... feeling! And what if, contrary to the technicist discourse, another captation was possible?
A dialogue between Emmanuelle Lallement, university professor at the Institute of European Studies of Paris 8 and urban anthropologist, and Léone-Alix Mazaud, doctoral student at Mines and innovation project manager at PCA-STREAM, whose Cifre thesis deals with sensitive data on urban biodiversity.
March 23, 2023 — 7pm - 8pm
They are everywhere in our cities but almost invisible... So what do these sensors look like? How do they work? And what do they really capture? To understand the behind-the-scenes of urban sensing, we will receive designers and operators of urban sensors.
A round table with Jean-Baptiste Poljak, CEO of Upciti, Caroline Goulard, CEO of Dataveyes and Modality, Laurens Vander Kuylen, project manager at Telraam and Sophie Vanwaelscappel, innovation manager at Lacroix.
March 8, 2023 — 7pm - 8pm
Data capture in cities is often justified by a security discourse. Surveillance cameras - among other urban devices - are thus intended to protect citizens. But if it seems natural today, this narrative is nonetheless a socio-political construction.
An exchange between Beatriz Botero, co-founder of The Edgelands Institute and Professor at Sciences Po, and Matheus Ferrari, PhD student in Urban Anthropology at the University of Paris 8.
February 16, 2023 — 6pm - 7:30pm
We have never collected so much data in cities. The public space is thus subjected to a real "dataification". But how can we explain this massive capture? What is it about? And what does it tell us about our time?
An inaugural lecture by Olivier Aïm, lecturer at Sorbonne University and author of Les Théories de la Surveillance, followed by an afterwork co-organized with Yourban, The Swarm Initative and The Good AI.
February 01, 2023 - 6pm - 7:30pm
Discover the results of a survey conducted on workplace management, based on a panel of 200 companies in the Ile-de-France region: impacts of telecommuting, diversity and types of workplaces, (re)arrangement of spaces, corporate culture, and the impact of the pandemic.
Presented by Julie Perrin, PhD in geography and urban planning, post-doctoral researcher at Gustave Eiffel University. This research was conducted with Anne Aguiléra and Laurent Terral (LVMT, Université Gustave Eiffel) as part of the Smart Lab Lability.
The Smart Lab Lability is an ephemeral innovation and research laboratory of the Gustave Eiffel University (February 2021-January 2023), funded by the Île-de-France Region. Nine research projects have been dedicated to studying the repercussions of the health crisis on the organization of work and the evolution of the mobility of people and goods in Île-de-France.
