An eco-neighbourhood

The reconversion of industrial and port land for the construction of a new sustainable neighbourhood


The Flaubert eco-neighbourhood project will contribute to regenerating a 90 hectare section of the city port interface, currently inaccessible but with significant urban potential. It will ultimately accommodate almost 10,000 users, making it an efficient solution to urban sprawl and the use of natural spaces by developing an urban wasteland that is heavily impacting the environment. This eco-neighbourhood project will offer 448,000 sqm of floor area including 42% housing, 4% business, 49% offices, 1% shops and 4% equipment. As part of its urban project management mission Egis implemented and monitored the project’s sustainable development management system, focusing on seven strategic objectives:

  1. Fully integrating the neighbourhood into its urban environment.
  2. Creating favourable conditions for alternative and sustainable travel.
  3. Creating pleasant living conditions for all.
  4. Achieving energy efficiency.
  5. Improving ordinary and extraordinary biodiversity.
  6. Making the most of the location of the site along the Seine.
  7. Involving local people and regional stakeholders.

Clip’and Clim

A “plug & play” active façade concept

An independent and resilient module for renovating buildings with minimal intervention, exclusively from the outside based on the principle of a multifunctional façade panel, completely prefabricated in the factory.

Energy renovation will necessarily rely on the building envelope, bringing it additional intelligence. The concept thus addresses several issues: “low carbon” rehabilitation, thermal and energy performance, air quality and comfort, cost control, rapid implementation, occupied site and/or phasing.

The Clip’n Clim module guarantees air quality and interior comfort, thanks to a double flow mechanical ventilation system, radiating panels for heating rooms  and air change for summer  with a dedicated opening. It is also possible to provide built-in photovoltaic panels.

Regional engineering

Financial constraints and a slight change in the relationship between spatial planning and urban design are causing officials to:

  • Make investment decisions.
  • Focus on adapting projects to regional development strategies.

With this in mind, the simple financial analysis of local finance is not enough. To meet this need, Egis has developed a consulting  and engineering service to support local authorities in optimising their internal operations (pooling, etc.), in the development of their regional strategy, the formulation of investment plans that will enable this strategy to materialise, and of course, more typically, as prime contractor on such projects.

Whether it be supporting prioritisation in projects, finding the best development method, setting up consultation strategies, or calculating a project’s financial profitability, etc. Egis has all the expertise required to study regional development in a systemic way, including technology, finance and governance.

Minimising the pollution and discomfort generated by urban works: a culture change.

The FURET research project (an ANR*/Advancity* project) was conducted with the assistance of leading organisations in project management, engineering, business and research.

chantier, construction, immeuble, gratte, ciel gratte-ciel, IGH, bâtiment, grue, grues,

After working together for the past four years, they have created an innovative “co-construction” approach for sustainable cities, offering key solutions for societal, economic and environmental issues. The results of this project consist of multiple combinable bricks that connect decision-making tools and models to the choice of the most discreet options. Processes and methods for better recording projects in all the complexity of a 24-hour city are available.

A method that involves:

  • Qualification of the different types of pollution and their level of discomfort.
  • A list of objectives for project management.
  • Incorporation into the design process and project reviews.
  • Control throughout the design phase (possible adjustments).
  • Monitoring of implementation.

The FURET project also enabled the development of a geographic information system (GIS) for project owners.

Eportfolio, a fully online app for the strategic and operational energy management of real estate

E-Portfolio is a tool for managing the energy renovation of property assets: it is used to manage and monitor the performance of operations at both strategic and operational levels.

eportfolio_maquette-04 eportfolio_maquette-05 eportfolio_maquette-01

It provides:

  • monitoring of the implementation of energy saving measures and updates key input data in line with developments and changes to the project and its context;
  • the comparison of actual performance achieved with the theoretical target performance, thereby  ascertaining which actions have been successful, and if appropriate, identifying possible blockages/failures;
  • dynamic simulation and modelling of actions on properties or buildings.
  • the information and exchange of messages within the user community.

E-Portfolio is a collaborative platform that can be simultaneously accessed by multiple users, who may have different access rights, configurable by the administrator and by the managers.

E-Portfolio is a fully online application arranged in three modules:

  1. an observatory that gathers, organises and archives information on asset management in a dedicated database.
  2. an action plan that defines, plans and prices up maintenance activities and upgrades.
  3. a real estate strategy for:
    • Prioritising and planning actions.
    • Monitoring the progress of actions and comparing the results with the objectives initially defined
    • Producing customisable reports characterising the status and performance of the property portfolio and its evolution over time.

A solution developed to support:

  • Landholding trusts and/or public and private property developers
  • Parties who have “bought” an energy transition plan and want to monitor it in real-time


Astainable demonstrator

Based on complete 3D modelling of the city of Astana, the capital of Kazakhstan, taking into account all the parameters specific to the area, the Astainable® digital demonstrator8 offers a wide range of French solutions tailored to the needs of the city that contribute to reducing its environmental footprint. Astainable® incorporates 350 French technical, industrial and engineering solutions in the areas of eco-mobility, energy, digital cities, responsible water and waste management and sustainable construction.

The need for sustainable cities is still as pressing as ever, driven by three key emergencies:

  • environmental, the consequence of rapid global urbanisation, with 2.5 billion more people living in cities by 2050;
  • social, a result of urban migration for economic purposes;
  • economic, which means building faster and cheaper.

This project relies on a consortium of stakeholders, business clusters, technological research centres, and French companies that work on the various issues involved in sustainable cities. In February 2014, it won the call for projects issued by the French Ministry of Foreign Trade, the Treasury Department (DGT) and the Mayor of Astana. The initiative showcases a digital demonstrator. This interactive urban design tool is intended to support stakeholders brought together under the Vivapolis umbrella brand, whose aim is to promote international sustainable urban development.

To this end, Astainable® is implementing eco-mobility solutions in order to provide multi-modal transport solutions that will reach across the city of Astana between now and 2030. In terms of urban ecosystems, the project is committed to protecting resources, through integrated management of the large water cycle, as well as promoting the services provided by nature, reintroducing local agricultural production in the city, and recycling and reusing collected waste. In the field of energy, the main goal is to achieve up to 30% renewable energy in the energy mix. Finally, efforts will be made to improve the entire existing building stock, through renovation and new buildings with very high energy performance.

The following have been put forward for this simulator:

  • A master plan for “fast and soft mobility”.
  • A complete network of public spaces that runs throughout the city, structures its urban composition, and reveals – through immersion in the simulator – a real comfort of use for its inhabitants.
  • An energy mix comprising 30% renewable energy, and smart solutions for the management of energy networks.
  • Innovative solutions to optimise the urban ecosystem in terms of:
    • waste (collection and energy recovery),
    • water (collection of the resource, supply, collection and treatment of storm water, recycling of grey water requalification of wetlands),
    • ecological engineering with a focus on “nature in the city”  (urban agriculture solutions),
    • eco-tourism to showcase the great Kazakh traditions.
    • sustainable construction (eco-lodges, summer residences, high performance buildings, etc.).

For this major project, Egis brought together its best engineers, urban planners, architects, sociologists, landscapers, etc., to offer responses suited to the context of this new urban space, so promising for French expertise.
