« Villes, numérique et innovation sociale : expériences françaises »

En pleine actualité liée aux enjeux de solidarité et d’accès aux services publics, cette publication questionne l’emploi des infrastructures et des usages numériques pour développer les cas d’usages en ville, dans la manière de nous déplacer, de consommer, d’interagir. Elle s’inscrit dans un contexte plus global d’urbanisation croissante et de densité démographique, interrogeant les enjeux de développement durable et de la qualité de l’air, de la mutation des transports et de la mobilité, la préservation des services publics et de l’accès aux soins ou encore la promotion du vivre-ensemble.

Une quinzaine de fiches, chacune dédiée à...

Over recent years, we have witnessed the constant growth of urban density all around the world: according to the United Nations (UN), around 70% of the world’s population will live in cities by 2050. This global phenomenon is associated with numerous challenges, such as sustainable development and air quality, the transformation of transport and mobility, the preservation of public services, access to health care and the promotion of living better together.
 
In this publication, France urbaine, an association bringing together major cities, inter-municipalities and metropolises across France, wanted to draw up a panorama of the initiatives implemented by urban centres to make living better together of the city. In keeping with the topical issues of solidarity and access to public services, this publication examines the possible existence of a specific French model of the smart city.
Smartseille, the eco-neighbourhood of the future to live in the present
La Ville de Marseille et l’établissement public Euroméditerranée réalisent dans les quartiers nord de la ville la plus grande opération de rénovation urbaine d’Europe du Sud. C’est dans ce cadre que "smartseille", le projet d’écoquartier conçu par Eiffage, a vu le jour : 58 000 m2 ont été construits sur 2,7 ha en associant harmonieusement logements, bureaux et services tout en offrant des logements et des bureaux à des prix accessibles et un accès aisé à toutes les nouvelles technologies.

Cet écoquartier du XXIe siècle apporte aussi à ses habitants comme à ses usagers le meilleur du développement durable :...
The City of Marseille and the Euroméditerranée public institution are carrying out the largest urban renewal operation in Southern Europe in the northern districts of the city. It is within this context that "smartseille", the eco-neighbourhood project designed by Eiffage, was born: 58,000 m2 were built on 2.7 hectares by harmoniously combining housing, offices and services while offering housing and offices at affordable prices and easy access to all new technologies.

This 21st century eco-neighbourhood also provides its inhabitants and users with the best sustainable development: supply of renewable energy, eco-design of buildings adapted to the Mediterranean environment, a mix of functions, urban agriculture.

With great technical ambition and with the help of Orange Business Services, smartseille promotes urban digital transformation and responds to new lifestyles and ways of working. Technology is not an end in itself but a means to make accessible innovative services that simplify the lives of residents, promote the development of social ties and encourage the sharing of resources: e-concierge, dynamic signage, interactive terminals, shared car parks. A web and mobile portal serves as a platform for interaction between residents.
Recyclean®: an exclusive process for reusing polluted roads
L’économie circulaire est déterminante pour l’avenir du BTP car elle contribue à préserver les ressources et à mieux gérer les déchets. Elle s’inscrit pleinement dans la transition écologique et l’innovation, deux des piliers du plan stratégique d’Eiffage.
 
Ainsi Eiffage Route a mis au point Recyclean®, un procédé exclusif de réemploi des chaussées polluées, notamment par des hydrocarbures aromatiques polycycliques (HAP) qui s’inscrit pleinement dans cette stratégie. Recyclean® permet de régénérer ce type de chaussées et de retraiter les matériaux existants. Cette solution ne génère pas de déchets, ni de...
The circular economy is crucial for the future of construction because it helps preserve resources and better manage waste. It is fully in line with the ecological transition and innovation, two of the pillars of Eiffage's strategic plan.
 
So Eiffage Route has developed Recyclean®, an exclusive process for reusing polluted roadways, including polycyclic aromatic hydrocarbons (PAHs), which is fully part of this strategy. Recyclean® allows this type of roadway to be regenerated and existing materials to be reprocessed. This solution generates no waste or landfill costs for polluted materials and fully meets the Energy Transition for Green Growth Act (LTECV) of 2015, which aims, among other things, to reduce the amount of waste admitted in storage facilities by 30% by 2020 compared to 2010, and 50% by 2025.
 
Ecologically and socially virtuous, the Recyclean® process avoids using new materials on construction sites as well as movements of trucks loaded with polluted materials. Recyclean® is also more economical because it avoids both the transport and the systematic landfilling of these materials.
"If the city" : for territory-wide consultation with all its users (EpaMarne)
Cet outil s’adresse à tous les usagers d’un territoire (habitants, étudiants, salariés, entreprises, voyageurs, touristes…) pour les conduire à s’interroger sur son évolution à long terme. A la fois simulateur et serious game, il propose à l’usager de se mettre à la place de l’aménageur et de relever les défis majeurs de ce territoire à l’horizon 2030 : résoudre la crise du logement, assurer un équilibre socio-économique, réduire le bilan carbone, etc.
Grâce au numérique, il donne à l’usager la possibilité d’expérimenter des choix d’aménagement, mais aussi de visualiser en temps réel les effets engendrés...
This tool is aimed at all users of a region (residents, students, employees, businesses, travellers, tourists etc) to encourage them to question its long-term evolution. Both a simulator and a serious game, it invites users to put themselves in the place of the planner and to address the major challenges facing the region by 2030: to solve the housing crisis, ensure a socio-economic balance, reduce the carbon footprint, etc.
Thanks to digital technology, it gives the user the opportunity to experiment with development choices, as well as visualising in real time the impact generated (need to finance public amenities, create jobs, congestion of transport networks etc) and the results achieved.
Having thus brought out an enlightened, shared vision centred on the general interest, this fun, educational tool aims to gradually deliver this vision at the local level, mobilising users at all stages of urban projects - including once the neighbourhoods and buildings have been delivered.
The digital web of South Alsace: benchmarks, stakeholders and digital issues applied to the industries of the future
Le numérique se diffuse à l’ensemble de l’économie. Si certaines activités sont strictement numériques assurant par exemple des activités informatiques ou de l’édition de logiciels, le numérique se retrouve aussi dans de nombreuses activités telles l’automatique industrielle, l’installation et la maintenance de lignes de production…
 
Au final, les technologies numériques se déploient, comme une toile, dans l’ensemble de l’économie.
L’enjeu, pour le territoire, est double. D’une part, il s’agit de faciliter la numérisation des entreprises industrielles. D’autre part, il s’agit de...
Digital technology is spreading to the economy as a whole. While some activities are strictly digital, such as computer activities or software publishing, digital is also found in many activities such as industrial automation, installation and maintenance of production lines and so on.
 
Ultimately, digital technologies are being deployed, like a web, throughout the economy.
The stakes for the region are two-fold. On the one hand, it is a question of facilitating the digitisation of industrial enterprises. On the other, it is about developing new activities, bringing added value and shaping the future.
 
This study provides an overview of this new ecosystem and the distribution of the roles of each local stakeholder in this "digital web".
Sustainable Building MOOC: a digital training offer dedicated to sustainable construction
En 2016, le Plan Bâtiment Durable et l’ADEME, en collaboration avec de nombreuses organisations et l’appui de France Université Numérique, ont lancé la plateforme MOOC Bâtiment Durable.
 
La Plateforme MOOC Bâtiment Durable poursuit deux grands objectifs :
- Permettre la montée en compétence des professionnels de la filière bâtiment et immobilier sur les thématiques de la transition énergétique et du bâtiment durable en général (construction et rénovation),
- Diffuser, auprès du grand public, une expertise des enjeux liés au bâtiment durable, en particulier la rénovation énergétique...
In 2016, the Sustainable Building Plan and ADEME, in collaboration with numerous organisations and the support of France Digital University, launched the Sustainable Building MOOC platform.
 
The Sustainable Building MOOC Platform has two main objectives:
 
  •  To enable the improvement of professionals ’skills in the construction and real estate sector on the themes of energy transition and sustainable building in general (construction and renovation),
  • To disseminate, to the general public, an expertise on issues related to sustainable construction, in particular the energy renovation of housing.
Proposed in collaboration with numerous partners, the training consists of video-type teaching resources (but not just that) and offers individual or collaborative activities to assess the knowledge of learners.
 
The ambition of ADEME and the Sustainable Building Plan is to provide access to the best online training MOOC in the field of sustainable construction, regardless of the geographical location of the different learners.
 
It is possible for all stakeholders in the sector to propose an idea for a MOOC or online training. All registration dates and terms are available on the Sustainable Building MOOC platform.
Luciole®, a safe and environmentally friendly solution for reducing the public lighting bill by more than 50%
L’éclairage public est un poste de dépense considérable pour les collectivités territoriales. Luciole®, la solution d'Eiffage qui allie un revêtement de chaussée clair, et des luminaires LED asservis à la détection automatique d’usagers, permet d’éclairer selon un « juste besoin » en faisant varier automatiquement l’intensité lumineuse en fonction de la présence et de la vitesse de déplacement des véhicules ou des piétons. Cette solution sûre et écologique assure une baisse de plus de 50% de la facture d’éclairage public.
 
Les LED de dernière technologie sont associées à un détecteur automatique de mouvement...
Public lighting is a major expense for local authorities. Luciole®, Eiffage's solution, which combines a clear road surface and controlled LED lights with automatic user detection, allows lighting to be provided "just as needed" by automatically varying the light intensity depending on the presence and speed of movement of vehicles or pedestrians. This safe and environmentally friendly solution reduces the public lighting bill by more than 50%.
 
The latest-technology LEDs are combined with an automatic motion sensor that adapts the lighting of each lamp post to the needs of users. Motion detection can be achieved using a variety of technologies: infrared, high frequency, video analysis or Doppler effect. The power delivered is reduced by 80% in reduced mode when the system does not detect any presence or when the choice of timeframe leads to such programming, which also reduces light pollution. A remote management tool allows you to control all or part of the installation in real time to control its consumption. Implementation involves both new and renovation projects.
 
Luciole® surfacing has a discontinuous 0/6 or 0/10 mm granularity comparable to that of a very thin bituminous concrete or sound coating. It reflects light in a diffuse way (multidirectional reflection) thanks to its composition incorporating particular light-coloured gravels. Its photometric properties allow the installation of lower lighting energy and better visual comfort. With these photometric properties, the Luciole® coating can also combine a remarkable noise-mitigation capability.

Eiffage, which has made innovation and ecological transition two of the pillars of its strategic plan, is setting up, in partnership with Impulse Partners, a specialist in construction innovation, "Sekoya", a carbon & climate platform entirely dedicated to low carbon materials and processes.
 
With climate change becoming a reality, Eiffage is committed to a low-carbon strategy. The Group wants to be exemplary, starting with curbing its own emissions, but as a construction sector leader, it also intends to support its customers in reducing their own carbon footprints, by developing alternative solutions and incorporating these as fully as possible into its offers.
 
Sekoya will help create a low-carbon industry club, by facilitating the identification of new and existing solutions and promoting interactions between all stakeholders., and by encouraging interaction between all parties involved. Committed partners (startups, SMEs, major accounts, suppliers, financial institutions) and customers will be able to discuss, document and promote low-carbon solutions. Once audited, these solutions will be available for use in tender proposals.
Power Road®: the very positive energy road
Avec Power Road®, Eurovia (filiale de VINCI) ajoute une nouvelle fonction à la route : la production d’énergie thermique.
Captée par le biais des rayonnements solaires, l’énergie solaire thermique peut être stockée puis restituée aux bâtiments et infrastructures environnants.
L’énergie ainsi produite contribue à chauffer des bâtiments résidentiels, des immeubles de bureaux, des commerces, des EcoQuartiers ou des équipements publics tels que les piscines, en améliorant leur mix énergétique.
Elle peut être utilisée également, en hiver, pour déneiger et déverglacer les voiries ou pistes d’aéroports...
With Power Road®, Eurovia (a subsidiary of VINCI) adds a new function to the road: thermal energy production.
Captured through solar radiation, thermal solar energy can be stored and returned to surrounding buildings and infrastructure.
The energy generated helps to heat residential buildings, office buildings, shops, EcoDistricts or public facilities such as swimming pools, improving their energy mix. It can also be used in winter to clear snow and de-ice airport roads or runways, thus reducing salting, and in summer to cool pavements and help reduce urban heat islands through surface heat capture.
 
With Power Road®, the road, without adversely impacting its primary use, can play a new role in the transition to a decarbonised economy. Power Road® won ADEME's "Road of the Future" call for projects under the Future Investment Programme (FIP).
Réussir la transition numérique des villes du sud
Installé dans la ville de Sémé-Podji au Bénin, Wexity est le premier outil digital spécialement conçu pour les autorités locales afin qu’elles puissent y gérer l’ensemble des objets urbains : réseaux, habitat, environnement, risques, économie locale, équipements… pour servir les besoins d’un développement urbain durable. Aujourd’hui seuls existent des systèmes experts complexes nécessitant du personnel qualifié. Wexity rompt avec cette logique de complexité.

Wexity est une plateforme digitale moderne, construite pour un usage partagé et collaboratif, conçue pour être accessible à tous les publics d’une...
Located in the city of Sémé-Podji in Benin, Wexity is the first digital tool specially designed to enable local authorities to manage all urban objects: networks, housing, environment, risks, local economy, equipment and so on, thus serving the needs of sustainable urban development. Today, only complex expert systems requiring qualified personnel exist. Wexity breaks with this logic of complexity.
Wexity is a modern digital platform, built for shared and collaborative use, designed to be accessible to all audiences within a municipality, from elected officials to senior managers and municipal technicians. We believe that only a solution used and controlled by local users can be sustainable.
Going beyond innovation of use, it is also our ambition to offer a major breakthrough in terms of controlling urban environments. In sub-Saharan Africa in particular, no city has an up-to-date and accurate map of its territory. The establishment of a complete and transversal database is in itself a decisive element for the cities of the South.
Innovation also comes from Wexity's ability to produce pragmatic analyses: how many people live in flood-prone areas? Which equipment is subject to environmental risk? Where are the areas that do not have access to drinking water? Which residential areas are furthest from schools? These are simple, obvious questions that cities are often not able to answer without external advice.
