City Introduction

Rennes Métropole (RM) comprises 43 cities including Rennes, the capital of Brittany. From the 17th century, Rennes has been renown for its University and the Parliament of Brittany.

Today, Rennes has the 3rd highest rate of population growth and GDP of French cities (and more than 60,000 students). Local economy includes car manufacturing, telecommunications, digital sector and agrofood. In  few years, Rennes has become one of the main centres in high technology industry and is the 2nd concentration of digital and ITC firms in France. Also, RM is often praised for the success of its land management policy (the Archipelago City model that manages urban-rural linkages) enabling a sustainable and inclusive territory.

Today, RM faces a challenge: how to keep on being an attractive place (expecting 200,000 new inh. within 2040) while preserving the current quality of life. The sustainable urban development strategy will focus on a smart cities strategy combining both ecological and digital transition.

Related Initiatives

3DEXPERIENCITY project, a partnership between RM and Dassault Systems that aims at developing a platform enabling the participation of all the urban development actors (building, retrofitting, energy and water management, mobility…). The main objective is to develop an innovative digital tool enabling a collective thinking on the city of tomorrow, together with professionals and inhabitants.  RM has developed its own 3D model on its entire territory. The platform provides visualization of complex data (an important challenge for smart grids issues) and should be a major tool for energy challenges.

OPEN ENERGY DATA (OED), a joint project with Telecom Bretagne (an engineering school) that aims at studying the feasibility of a home tracking module for personal electricity consumption with the view of releasing data within an open data approach. It therefore aims at allowing citizens to take back energy for themselves. To collect the data, a new network technology is currently being developed by Telecom Bretagne: LoRa Fabian (a long-range radio technology for the IoT). An open source platform to manage and visualize big data is also being developed.

RENNES GRID, a smart grid project on an existing tertiary and academic activity district scale. Initiated by RM and Schneider Electric, the project is at the feasibility stage, and a consortium of 5 partners has been set up. It intends to be a pre-industrial demonstrator for a large scale rollout, aiming to implement self-consumption of green energy at the local scale, by smartly sharing the photovoltaic production between surrounding buildings while reducing their energy consumption, without the help of any public subsidy.

KORRIGO SERVICES: The project aims at opening the transportation card “Korrigo” to new usages. Currently, several cards exist in parallel (for swimming pools, libraries, discount cards, etc.) with perhaps over 150,000 different cards nationwide. The idea is to have a single format enabling easy access to public services, based on the KorriGo travelcard. It aims at integrating transport, bank, academic, and urban services on NFC, cards, phones and USB devices. This interoperability allows a seamless mobility and usages for users. Citizens will enjoy enhanced access to public services by choosing their preferred data medium (card, cellphone or usb device). The technology must be aimed at all citizens and avoid any digital divide: some people do not own cellphones or may not wish to use their phone in this way. The aim is to integrate credentials in the card, allowing citizens to access other services if they wish. The use of credentials is a simple process enabling citizens to be linked to databases belonging to service providers (swimming pools, libraries, etc.). Dedicated web portal functionalities will include:

  • services that can be accessed and, potentially, other services too
  • topping up swimming pool or transport accounts via a payment system, etc.
  • organization of access to services for family members
  • easy access to city services

This means cities wishing to offer access to public services using existing cards and/or mobile apps can do so at any time, and costs can be shared. Local solidarity and compatibility are important aspects. Ubiquity and ease of use are key concepts for this innovative system.

LAB FAB ETENDU: The Extended Fab Lab project aims at making available digital fabrication tools to people within community centers and schools.

The Rennes Fab Lab has two assets :

  • It enables to move from idea to prototyping
  •  It provides access to a community of user/testers and to a mesh network of skills
