Towards sustainable airport areas
Dans un contexte de mondialisation croissante des échanges, d’intensification des flux internationaux de marchandises et de personnes, et de hausse globale du trafic aérien qui en découle, les aéroports internationaux constituent des atouts stratégiques pour le développement et l’attractivité des pays et territoires qui les accueillent et qu’ils desservent. La présence d’une place aéroportuaire génère des interactions multiples, entrainant des externalités positives (retombées économiques en termes d’emplois, fiscalité locale, desserte en transports…) ou inversement négatives : pollution atmosphérique, nuisances sonores, congestion...
In a context of increasing globalisation of trade, increasing international flows of goods and people, and the resulting global increase in air traffic, international airports are strategic assets for the development and attractiveness of the countries and territories that host and serve them. International airports and their surrounding areas are of increasingly strategic importance for the development of the metropolitan regions they serve. They are also evolving and becoming distinctive economic and urban places in their own right. At the same time, airport activity has a significant impact on the surrounding environment and generates positive externalities such as economic spin-off in terms of employment opportunities, taxes paid from airport business, transport services, etc. or negative externalities such as air pollution, noise, traffic congestion or agricultural land consumption, etc. Airport areas therefore face many challenges of their own, which need to be addressed at this territorial scale.
 
The Institut Paris Region launched the « sustainable airports” initiative in 2015 with the support of the NGO Metropolis. Three workshops on this theme were organized between Paris and Atlanta. This report stems from this initiative. It is divided into seven thematic chapters, dealing with the major challenges for sustainable airports, making recommendations and highlighting good practices, basing itself on the collective work carried out by the workshops ‘participants and additional research led by the project team.
ActivSkeen: an energy-producing building envelope
Parce que demain se construit aujourd’hui et que le bâtiment est aux avant-postes de la transition énergétique, de la lutte contre le changement climatique et de l’évolution des modes de vie et de travail, ActivSkeen crée des solutions de façades et d’enveloppes actives et esthétiques réduisant l’empreinte environnementale du bâtiment et améliorant le confort des occupants.
 
Ainsi ce n’est plus, un élément de façade assurant les fonctionnalités d’étanchéité, d’isolation et de ventilation, qui est installé, mais un élément produisant, en plus de ces fonctionnalités de base, de l’énergie. ActivSkeen fait appel...
Because tomorrow is being built today and building is at the forefront of the energy transition, the fight against climate change and changing lifestyles and work, ActivSkeen creates solutions with facades and active, aesthetical envelopes that reduce the building's environmental footprint and improve occupant comfort.
 
So it is no longer about installing a façade element providing the functionality of waterproofing, insulation and ventilation, but an element producing, in addition to these basic features, energy. ActivSkeen uses built-in photovoltaic technologies (BIPV) as well as dynamic glazing solutions. It controls the entire value chain, from the design of materials to their installation and implementation engineering.
 
These solutions help produce positive energy buildings (PEBs) and energy self-sufficiency at the islet or neighbourhood level. The interfaces are simplified for better control of projects, from the first draft to
closing the construction site.
Trilib', self-service waste sorting
Pour permettre à plus de Parisiens de trier plus simplement et pouvoir apporter une solution aux 10 % de Parisiens n’ayant pas de bac jaune, Citeo a conduit et financé une expérimentation à Paris : 40 stations trilib’, des containers de collecte de proximité disponibles 24h sur 24, implantés dans 4 arrondissements.
Mobilier urbain de tri et modulaire, la station trilib’ mutualise 5 flux : les emballages en verre, en métal, les bouteilles et flacons en plastique, les papiers et cartons et enfin les textiles. Innovation digitale et service à l’usager, les taux de remplissage des stations sont disponibles en temps réel sur...
To allow more Parisians to sort their waste more simply and be able to provide a solution to the 10% of Parisians who do not have a yellow bin, Citeo conducted and financed an experiment in Paris: 40 trilib' stations, local collection containers available 24 hours a day, located in 4 districts.
Modular urban sorting furniture, the trilib' station brings together 5 streams: glass and metal packaging, plastic bottles and containers, paper and cardboard, and finally, textiles. Digital innovation and user service, station filling rates are available in real time on the opendata.paris.fr platform.
The City of Paris has decided to deploy these stations that facilitate waste sorting and collection.
Each station collects around an additional 25 tonnes of packaging each year and improves the quality of sorting.
For 9 out of 10 Parisians, they are easy to use and show that waste sorting is really useful. Since 2017, this still experimental arrangement has already allowed the sorting and recycling, among other things, of 55 tons of plastic bottles, or about 2 million bottles.
A thousand Trilib' stations will be deployed throughout Paris from the end of 2019 to 2021 by the City of Paris with the support of Citeo.
 
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.
Energy transition and urban planning video: how to move towards sustainable cities?
Croiser les enjeux de l’environnement, du climat, de l’énergie et des réseaux avec les politiques de l’urbanisme, de la mobilité et de l’habitat est essentiel pour construire des projets de territoires durables. L’aménagement des territoires est le levier le plus efficace pour réussir la transition énergétique dans la mesure où il impacte directement la demande en énergie.
 
Il peut par exemple créer des villes dépendantes de la voiture et très minéralisées, ne permettant pas de réguler les températures, ou tout au contraire des villes économes et résilientes offrant un cadre de vie attractif à leurs...
Combining environmental, climate, energy and network issues with urban planning, mobility and housing policies is essential for building sustainable regional projects. Land use is the most effective lever for successful energy transition as it directly impacts energy demand.
For example, it can create car-dependent, highly concrete cities which do not regulate temperatures, or, on the contrary, economical, resilient cities offering an attractive living environment for their inhabitants.
Thus, a well-organised region, sufficiently dense which makes the most of its local resources, can at the same time reduce its energy needs, produce its own energy and adapt to the climate of the future. The urban planning code now offers opportunities that communities can seize on.
This video, produced by Agam and DREAL Provence Alpes-Côte d'Azur, in association with the region's technical services, is a relevant way of presenting legal levers and making them possible by local examples of successfully integrating the energy transition into urban planning. Elected officials, experts and planning stakeholders, it's up to us!
Protecting Oshakati from heavy flooding during the rainy season
La ville d'Oshakati est l'une des plus grandes villes du nord de la Namibie et souffre régulièrement de fortes inondations pendant la saison des pluies.
 
En collaboration avec son partenaire IMDC, Tractebel a développé une solution durable afin de protéger Oshakati de ces inondations. Cette solution consiste en la construction d'une digue au nord-ouest de la ville ainsi que de ponts et d'écluses pour détourner et contrôler les eaux d'inondation venant de l'Angola autour de la ville. Au sommet de la digue, une partie de la future rocade sera modélisée en 3D et construite selon le plan directeur...
Oshakati is one of the largest cities in northern Namibia and regularly suffers from heavy flooding during the rainy season.
 
In collaboration with its partner IMDC, Tractebel has developed a sustainable solution to protect Oshakati from these floods. This solution involves constructing an embankment to the north-west of the city as well as bridges and locks to divert and control floodwaters coming from Angola around the city. At the top of the embankment, part of the future ring road will be modelled in 3D and built according to Oshakati's design master plan.
 
Key project issues include:
 
  • Defining the necessary measures to adapt community development to climate change, taking into account the relative urgency of the risks identified and available resources in collaboration with all local stakeholders;
  • Developing land use including better management of water resources: run-off, groundwater, rivers, estuaries, coastal waters and designing flood protection measures.
