GRAND PARIS EXPRESS STATION
With lines 11, 15 South and 16 interconnected to the RER A at Noisy – Champs station, Cité Descartes, located just 25 minutes from the centre of Paris, will become a new hub in Greater Paris, the epicentre of a new way of conceiving and living in the city. The opening of the Grand Paris Express line 15 South at the end of 2025 will be the first step in this dimensional shift.
The future Noisy-Champs station of the Grand Paris Express and the construction sites surrounding it form a 1 km long area, one of the largest of the Grand Paris Express. Work began at the end of 2016 on the rear station and mid-2017 on the front station.
Built around the RER A tracks, the station will eventually bring together the new metro lines and RER line A under its Chinese roof. The RER will pass under the central hall below the street; line 15 South will run on level -1 with platforms 13.5 m below ground, and line 16, from 2018, on level -2, located 21 m below ground. Outside, a bus station will provide connections with 10 or so bus lines.
With a total of 6 accesses, it will efficiently service the surrounding districts and their 23,000 inhabitants within a radius of 1 km. It is expected to see a football of up to 150,000 passengers per day.

INNOVATION TERRITORIES: BUILDING FOR THE FUTURE, LIVING IN THE FUTURE
“Innovation territories” is an action of the Grand Plan d’Investissement, backed by the third wave of the Future Investment Programmes (PIA). The aim of this scheme is to createthe territories of the future and new models of territorial development. Coordinated by the Ile-de-France Region, the project Construire le Futur, Habiter le futur (Building for the Future, Living in the Future) aims to respond to the major challenges of the Region and to support the digital and ecological transition of the housing and construction sector in Ile-de-France.
Among the projects of Construire le Futur, Habiter le futur, many actions are carried out in Cité Descartes:
- ECOLAB Sustainable City Digital Campus: improving the understanding, application and participation of users in sustainable development solutions on the campus via innovative digital services (ESIEE Paris, EIVP)
- Creation of a raw earth construction sector: contributing to the development of a raw earth construction sector (available, local, low grey energy and infinitely recyclable construction material) in Île-de-France (Gustave Eiffel University, EpaMarne, Alkern)
- Opening the campus to new uses and polyactivity: Cœur de campus (co-construction of a living space for campus users and residents), Fabrique des Savoirs (scientific mediation activities for the general public) (Université Gustave Eiffel)
- LORE: Software for 3D reconstruction of real environments and evaluation of user behavior using virtual reality (Gustave Eiffel University) – Generation of digital twins of real environments for the 2030 smart platform, supporting a better understanding of the use of the city by the inhabitants of the Region, a complement to the city planning tools for local authorities
- SILAVILLE consultation and planning platform (EpaMarne, Efficacity, Elioth, EUP)
- Transversal evaluation of citizen participation and co-construction (Université Paris-Est Créteil)
- General wood construction company: creation of a new industrial player in the wood construction sector (Ecole des Ponts ParisTech, Mazenq)
- Hekka Factory of the Future: production of quality buildings, built quickly and at controlled cost to meet the needs of a maximum number of inhabitants (Ecole des Ponts ParisTech, Agence Coste, CSTB, HAL Robotics, Supratec, XtreeE)
- Releasing shared value: encouraging the emergence of business models based on shared value, so that the growth of companies is built within the framework of a sustainable development approach (Ecole des Ponts ParisTech, Efficacity)
EpaMarne, the research and development centre dedicated to urban energy transition Efficacity and Université Gustave Eiffel are committed to the implementation of an experimental territory on the Cité Descartes campus, in order to imagine and design the cities of tomorrow. The Smart&Sustainable Campus partnership agreement aims to deploy demonstration projects on the campus and its surrounding area, in partnership with the site’s public and private socio-economic players.

INTENCITÉ DESCARTES, TRUE DEMONSTRATOR OF THE SUSTAINABLE CITY
The Intencité Descartes project deployed at the heart of the Cité Descartes by Linkcity (following the Ecocité 2 call for projects), and accompanied by the architectural agencies CoBe and Tolila & Gilliland and Franck Boutté Consultants (AMO Sustainable Development), includes several remarkable innovations.
Covering almost 30,000 sqm, Intencité Descartes is an urban demonstrator aimed at creating attractive living spaces near the railway tracks of the Noisy-Champs RER A station.
Lot B1 is a mixed real estate programme comprising 4,055 sqm of offices, 106 housing units in an intergenerational complex, 236 family housing units and 2,800 sqm of shops and services (shared gardens, connected housing, digital concierge service, coworking spaces, music crèche, restaurants, etc.).
EpaMarne has brought together this project, in order to accelerate the energy and ecological transition of cities and to promote the attractiveness of Cité Descartes, promoting inclusion and social diversity in the City of Tomorrow.
The lot provides solutions to optimise user comfort, such as innovative acoustic facades (perforated panels with mineral wool, treatment of the undersides of balconies and loggias), anti-vibration devices and acoustic modelling at the block level.
The energy performance of the Intencité Descartes project is ensured through bioclimatic architectural structures and a geothermal supply.
The city of the 21st century will be connected. Thus, lot B1 imagines a programmatic mix, an intergenerational island and shared living spaces (guest rooms, rooftop, shared gardens, 5-sense walk, circular economy, restaurants and coworking spaces). It also includes the construction of buildings using BIM and connected housing facilitated by the use of digital application opportunities.

THE NAUTICAL STADIUM OF VAIRES-SUR-MARNE
LIn 2024, the Nautical Stadium of Vaires-sur-Marne will host the Olympic rowing events as well as the pararowing and paracanoe events of the Paris 2024 Paralympic Games at the leisure complex of Vaires-Torcy. It is the first newly built Olympic facility to have been delivered, in 2019.
Designed by the architects Auer+Weber+Assoziierte, the complex is built around the lake and the white water stadium, which houses new buildings with its landscaped roof, is accessible to the public.
The 4,400 sqm sports centre includes the new white water stadium with its two courses (300 m and 150 m), the rowing and sprint canoe-kayak course (2,200 m), a medical-sports annex, a weight-training centre, administrative areas and a media centre. There is also a training and accommodation centre.
A convention place for the representative bodies of these water sports and as host for the athletes, the complex constitutes a centre of excellence for sport: on par with Beijing and Sydney. It is one of the three sites in the world capable of simultaneously accomodating the Olympic and Paralympic canoeing and rowing events.
It has the capacity to accommodate between 12,000 (slalom canoeing, paracanoeing) and 24,000 spectators (canoeing and rowing).
This outstanding one-of-a-kind project in Europe, is located on a 150-hectare site designed as a “breathing space” in an urban environment. The new infrastructures were built in the framework of a high environmental quality (HEQ) approach, guaranteeing the protection and enhancement of the area. The white water stadium allows the leisure complex to expand its existing offer (rowing, canoeing, catamaran, stand-up paddle, windsurfing or optimist) for the people of Ile-de-France Region along with rafting and hydrospeed, as well as canoeing and kayaking.

The former “École Louis Lumière” is located near the Noisy-Champs RER A station, the future hub of the eastern part of the Ile-de-France region connected to lines 15 and 16 of the Grand Paris Express, and line 11 of the metro.
Close to the Cité Descartes Sustainable City Cluster, the 3.8 hectare site is at the heart of a residential area made up of large housing estates and detached houses. Entirely wooded, it is conducive to the regeneration of the district, with the enhancement of the architectural and landscape heritage.
The Révélation Lumière project (winner of the call for architecture and urban planning projects Inventons la Métropole du Grand Paris, IMGP 2) will be a place of research and experimentation, a factory and showcase of a human city where life is good. In France, it will be the first hub in the ecodesign of the sustainable and inclusive city of tomorrow.
Révélation Lumière will include a coworking space (Le Révélateur, formerly known as École Louis Lumière), a third area with a café-canteen, a modular space, a repair workshop, climbing walls, etc. The project includes a residential area that encourages diversity and exchanges through its multi-faceted programme initiatives.
Educational and fun activities for users and residents will be continuously organised. The vegetable garden and the shared gardens will help the community in developing new ecological habits.
This new district will be built around a central park with a water feature.
Owners: État, Grand Paris Aménagement, Ville de Noisy-le-Grand
Teams: Land’Act / Reichen & Robert Associés (architects) / Brenac & Gonzalez Associés (architects).

SMART GRIDS GEOTHERMAL ENERGY
The logic of smart grids which is, above all, collaborative, mixes energy sources (fossil and renewable, central or local) and, thanks to the collection and analysis of data via information systems, makes it possible to pool resources in order to smooth out consumption peaks by transferring surplus production to third-party networks.
The storage of electrical energy is a major challenge and innovations in this area are very rapid and promising. We can store electricity in the metal structure of a building, heat a swimming pool at night and recover the heat in the morning…
Our territory is consolidating its pioneering heritage. The heating network of the Paris-Vallée de la Marne Urban Community operated by ENGIE Solutions was designed to offer a clean, local and renewable heating and hot water solution, powered by geothermal energy. Eventually, this network will serve 10 districts in Noisiel and Champs-sur-Marne and the equivalent of 10,000 homes.
Smart grids are being studied for deployment in the Cité Descartes.

ENERGY EFFICIENCY RENOVATION COURSE FOR HOUSING
The Energy Efficiency Renovation Course for Houses project (PERP) is directly linked to the selected applications of all the 14 cities composing Grand Paris Grand Est to the call for expressions of interest of the Greater Paris Metropolis to support the energy efficient renovation of suburban areas.
This project is in line with the Metropolis’ action in favour of the energy transition of the residential sector undertaken within the framework of the Metropolitan Climate Air Energy Plan and the Recovery Plan voted for in May 2020. This action is also included in the Energy Renovation Support Service (SARE) programme. It is carried out by the general management of Grand Paris Grand Est in coordination with the Housing and Urban Renewal Department and the Economic Development Department.
Private individual housing represents 36% of the Grand Paris Grand Est housing stock, i.e. approximately 40,000 private single-family homes built before the first thermal regulations of 1974. This is therefore an old, private and mostly energy-consuming housing stock which is a lever for reducing the thermal footprint, fighting against “poor housing” and fuel poverty. This would represent a significant volume of turnover (between €25M and €35M) within the reach of the Territory’s craftsmen businesses.
A study (TREMI) carried out by the Ministry of Ecological Transition and the ADEME has shown that only 5% of renovations carried out between 2014 and 2016 have resulted in at least 2 energy labels being gained. This success rate is justified when the household is involved in the scope of work to be undertaken. This is why the PREP supports households in carrying out comprehensive energy renovation work
Each of the municipalities in the Territory has therefore undertaken to implement the PREP so that 500 houses per year can be renovated in the Grand Paris Grand Est Territory.
