Design data to structure, contextualise and view the city

Egis has developed customised applications to ensure direct, comprehensive and unbiased access to data. An example of this being “Métabolisme Paris”.

This visualisation tool was created by Elioth* in 2014 to popularise the concept of urban metabolism for policy makers, project leaders and citizens, by showing the flows of energy, resources and water that form the lifeblood of the city: how much electricity, gas, oil, heat, consumer goods, food and drinking water enter Paris each year? Does the city export more goods than waste? To what extent is it dependent on energy imports? Is autonomy possible for a city this size?image-metabolisme-paris

Designed for the “Optimisation du Métabolisme Urbain” (Urban Metabolism Optimisation) call for projects launched by the City of Paris, the website presents over 40 local projects, examples of concrete circular economy solutions, already in place and functional: how can paving stones be reused rather than manufacturing new ones? How is the sand from Paris Plage recycled every year? How can waste be turned into reusable materials or energy?

*Elioth is an Egis entity specialising in innovative structures, building envelopes, and environmental design


“Métabolisme Paris” has been nominated for the CityVis award and was presented at the UN summit Habitat III held in Quito from 15 to 20 October 2016. 

Urban renewal project in Les Mureaux (France)

Launched in 2006, the project has restructured the whole of the urban network and public spaces within the scope of the ANRU project. A street-by-street landscape project ensured that stormwater issues were addressed well in advance, in accordance with the site’s irregular terrain. As the project’s centrepiece, the Molière gardens give structure to the whole of the urban fabric. Currently under construction, they will be delivered in 2017. With the reopening of a waterway and the creation of filtering gardens, the planting of orchards and kitchen gardens, plus play areas and meeting places, this landscape environment will become the backbone of a rediscovered urban conviviality.

Les Mureaux espaces publics, projet ANRU

The town of Les Mureaux, SEM92, Atelier Villes & Paysages and Infraservices have been awarded a prize by Innovapresse – Les Défis Urbains 2016 (Urban Challenges 2016) in the category “climate adaptation of the urban landscape and water management” for the Les Mureaux urban renewal project.

The Défis Urbains awards recognise the achievements of public and/or private initiatives for a sustainable, inclusive, accessible, shared, innovative, connected, balanced, comfortable and economical city.

Faced with the small size of its territory, the Principality of Monaco has launched a new offshore urban development project to create an eco-district on a six-hectare land reclamation site between now and 2025. Alongside the concessionaire, made up of Monegasque shareholders and the Bouygues group, Egis is designing all the maritime infrastructure for this major project.

Between the cove of Portier and the Grimaldi Forum, a new district is about to emerge, bringing the total area reclaimed from the sea to 40 hectares, some 20% of Monaco’s surface area. A major challenge for the Principality! The construction of a six-hectare eco-district will not only help to revitalise Monaco’s town planning, but also accommodate a rapidly growing population.


Egis is designing all the maritime infrastructure for this major project. Hydraulic and geotechnical expertise were harnessed from the very first studies in order to identify the project’s constraints. Seabed depth, geology, and the effects of the swell and seismic risks are just some of the many factors to be considered when establishing the sustainability of these infrastructures.

The study phase required constant interaction with the various project stakeholders, to ensure that all of the project’s issues are incorporated at every stage of the work. In addition to the technical aspects, it is environmental considerations, which are of primary importance for the Principality, that guided the overall design.

The new coastline created by this extension will lie at the centre of two natural areas: the Larvotto Reserve and the Spélugues coral reef. “Measures will be taken to move and restore protected species (Noble pen shells, Posidonia seagrass, etc.) outside the project zone. There will be constant monitoring of the risks of turbidity (particles suspended in the sea) during the construction phase. Finally, being mindful to protect biodiversity, the façades of the caissons have been specially designed to be able to host marine fauna and flora.


Egis’Scope, a multi-site data management and collection tool on iPad for audits and master plans

In the current economic climate, more and more property owners and investors need to be supported in their strategic property management decisions. Whether it be field works, light and heavy rehabilitation, acquisition of real estate, or strategic property plans, many processes require the support of teams of technical experts to assess the quality and potential of real estate assets.

At a time of web 2.0 and digital technologies, we naturally turned our focus to a tablet tool that could systematise our audits and give our customers a better basis for decision support.

We therefore developed a tablet app designed to establish the current architectural and technical condition of a building in near-real time.
The aim is to determine the performance of existing buildings for rehabilitation, or for the sale and purchase of real estate.

Online customer service satisfaction survey


– Simple and direct identification of each piece of equipment analysed on the building plan.

– The capacity to name and list each piece of equipment and classify them by technical batch for an overall organisation that is accessible and user-friendly.

– A comprehensive, exhaustive inventory in the form of predetermined data sheets containing information specific to each piece of equipment.

Structured into two distinct steps:

  1. A complete technical and architectural inventory in the form of data sheets that engineers fill in after a site visit.
  2. A scoring system based on four criteria for assessing the quality of the building and optimising its full analysis.

Based on a building plan, the EGIS’SCOPE tool is used to list and reference all building equipment through location points directly displayed on the plan with reference to the technical data sheets.

This referencing on the plan is directly linked to the data sheet referencing, so that the connection between the plan and the data sheets is crystal clear.

Data sheets are grouped into batches, by structure, and are compiled into an overall inventory report.

Each data sheet filled out by our experienced engineers includes the following information:

  • A technical description of the equipment
  • A comments section
  • A photo or photos of the equipment
  • Rating of the equipment according to 4 criteria

The tool analyses this information to achieve an instant overview of indicators on a summary table.

A manual on energy transition for buildings and citie

The convictions and solutions of design engineers

manual only available in french
Manual only available in french

Egis’s design engineers have written this manual to explain energy-related issues in a simple and informative way, to educate our partners and clients on the simple, accessible and user-friendly solutions available. The hope is that this manual can also help develop solutions for energy rehabilitation and the fight against fuel poverty.

A manual about energy, a user guide giving everyone an insight into the science and technology

At a time of national debate on energy transition, Egis was keen to make sure that energy doesn’t remain the sole preserve of experts: first and foremost, there needs to be rapid change in our culture and overall understanding of the challenges and possible solutions. By publishing this manual, Egis also wanted to create a “workroom” for simple and sound solutions that are easy to implement.

This manual is organised around two main chapters focusing on:

  • energy “a user guide”: this chapter provides the keys to understanding what energy is as a whole, by giving simple definitions and examples to illustrate: what is primary energy, embodied energy, what units are used, what is meant by the overall energy cost, energy efficiency, etc. And finally, the manual takes a look at the various alternative solutions to oil while explaining the advantages of light, biomass, geothermal power, and more.
  • the second chapter focuses on taking action, particularly on the benefits of offering overall optimisation of solutions (instead of cumulating individual optimums), innovating and adopting strong and consistent strategies across all challenges (life cycle approach), ensuring long-term energy performance, and finally, facilitating discussion of complex issues by providing a single contact point for customers and project partners.

In the manual’s conclusion, Egis presents some of its iconic projects and offers a bibliography for all readers who want to know more about Egis’s expertise in the field of energy.

  • The French Ministry of Defence, Balard site: three-quarters of annual heating and cooling needs, as well as ventilation, are provided by high-performance systems, particularly through interaction with the surrounding environment (air, geothermal power) and the energy recovery of buildings
  • Allianz Riviera Stadium in Nice (France) : a positive energy building. The stadium’s envelope is made up of a three-dimensional mixed wood and metal structure covered with PVC and ETFE canvas and a photovoltaic system. Geothermal energy to produce hot and cold air, and implementation of a photovoltaic power system with a surface area of 8500 sqm, making this an eco-positive stadium.
  • Villages Nature (Seine et Marne/ France):  over 97% of the site’s heat supplied by a renewable geothermal source
  • The NEF (building in Tours/ France), a social rehabilitation project with high architectural and energy performance. An innovative system for producing head and cold based on geothermal power. The project management and EPCM adopted the principle of using geothermal energy and producing the least amount of cold possible. Current drilling for geothermal energy is at 60m deep. It allows for a flow rate of 22 m3/h with a water temperature of 16°C. It is then stored in a tank of 140 m3 then feeds three water-to-water heat pumps. These pumps operate either together or independently to produce water at 45°C for heating and 65°C for hot water. The system is used to heat homes, while cold is stored in the 140 m3 tank. This is used to cool offices, via radiant ceiling equipment. This principle provides satisfactory comfort without air conditioning (the offices face east). It therefore capitalises on the multi-functional nature of the building by using the heat on one side and cold on the other.

Adapting urban furniture to its surroundings. Using cellter as an example, a photovoltaic canopy structure

Developing “smart” and multifunctional public facilities (lighting, energy production, internet connection, etc).

Elioth, an Egis entity, designs street furniture integrating energy production solutions.

For example, with its Cellter project, Elioth has created a photovoltaic canopy structure for sheltering vehicles and recycling rainwater

Cellter photovoltaic shelters enable production of energy in urban spaces already occupied for other purposes. Its special design means it can be adapted for use in car parks or integrated with urban furniture (advertising display panels, bus shelters, kiosks, etc). Elioth lab is proposing a new low-cost design to optimise the electricity production of a photovoltaic parking shelter. Drawing its inspiration from solar concentrator systems, the Cellter photovoltaic shelter is based on the principle of concentration of radiation by a fixed reflector. The system uses a mirror to reflect as much sunlight as possible onto the photovoltaic surface to ensure optimum electricity production.

Designing the development of the Nouadhibou free zone (Mauritania)


The Mauritanian economy is based on exports of iron ore, fishing and port activities. The government has made the Nouadhibou Bay a free zone. Created at the start of 2013, the zone extends over more than 1000 sqkm and is home to a population of 100,000 which could rise to 400,000 by 2030. Egis, under its “My City by Egis” banner, has been tasked with establishing a vision for the region and with expediting its development. As part of this project, Egis put forward a development plan for the next 15 years based on an Operational Master Plan (OMP) and a Multi-Annual Development Plan (MDP).

Zone franche de Nouadhibou, Mauritanie

The aim? To strengthen existing economic activity, develop tourism and service-sector functions and to design an urban development project to catalyse attractiveness for tourists and contribute to the well-being of the inhabitants. Egis’s main proposals were:

  •  neighbourhoods well connected to a public transport system (dedicated public transport corridors),
  • neighbourhoods that combine shops and facilities for a mix of various uses
  • Business areas directly connected to travel hubs (port and airport) with minimum environmental disturbance.
  • Urban growth will happen preferentially via increased density, whilst preserving outside areas that are important for the inhabitants.
  • The creation of a green belt acting as a windbreak for the city will also allow urban market gardening and livestock rearing under palm plantations, both of which are in line with local tradition.
  • And lastly, water is at the heart of this project with the introduction of facilities for desalination and generalisation of wastewater treatment which will then be partially used for irrigation.



El Ménéa, a modern sustainable city in a palm grove in the middle of the desert

The Algerian Government, aware of the rural exodus and noting the uncontrolled rise in slums in Algiers and Constantine, has launched several major operations to reduce precarious housing projects and work on plans for many new cities. A modern, sustainable city located in a palm grove in the middle of the desert that would address this critical problem of housing: this is the challenge taken on by Egis, which has finalised planning studies for the new city of El Ménéa, 270km south of Ghardaia.

Master plan de la Ville Nouvelle d'El Ménéa, Algérie

The choice of site for the new city came down to various favourable criteria, including its proximity to the administrative centre of the daïra and the RN-1 (trans-Sahara) motorway, its proximity to essential infrastructure (water, electricity, gas), the presence of local building materials on site, and the existence of a business park and an agricultural area nearby.  This city, which will extend over a plateau, fits perfectly into the urban development master plan of the old town of El Ménéa, by preserving the region’s palm grove and water table.

According to officials of the Wilaya province, construction of the new city will meet the pressing needs of a strong demand for housing as well as jobs for young people in the region.

Some 5000 to 6000 temporary and permanent jobs will be created in the building and public works sector as well as in services. Rehabilitation work for the ancient palm grove of El Ménéa and its irrigation system will also be undertaken to preserve the date palm culture and heritage of the region, whose position as a centre for tourism excellence will be strengthened further.

The challenge is to create a fertile, mobile and populated city on a relatively inhospitable site: a stony hamada, between sandy desert and oasis, where water management is crucial.
The city will benefit from sustainable contemporary buildings whose techniques are inspired by bioclimatic architecture adapted to desert environments. Between now and 2020, 10km north of the current El Ménéa and spread across almost 2500 acres, the new city is set to house all the amenities of a modern and environmentally friendly city, with a focus on tourism and agriculture.

A new kind of university building in brittany, dedicated to digital technology

To bring campuses permanently into the digital age, the Université Loire Bretagne (UBL) has launched the construction of four new buildings using a High Environmental Quality approach. These four buildings are spread over several campuses at the UBL, two buildings are located in Rennes on the Beaulieu and Villejean campuses, while the other two were built on the Bouguen campus in Brest and at the Technopole at Brest Iroise, overlooking the ocean.

Campus numérique de Bretagne, Rennes

Egis worked on this project as project manager, and provided project management consultancy for all the Environmental PMC and monitoring of certification. The advantages of this real estate project are:

Energy: the four buildings are covered by a performance contract between the builder and the UBL, which has resulted in a building design focused on energy efficiency and comprehensive operational monitoring to ensure this performance. Several choices were made during the design phase to meet performance goals:

  • The choice of exterior insulation reduces the need for thermal bridges and provides high thermal inertia, which – when combined with nocturnal ventilation – can delay temperature rises in the summer.
  • The university is connected to the district heating network.
  • The premises are heated by radiators with low thermal inertia, which optimise the consumption per room based on internal and solar gains, except in the lobby where under-floor heating has been installed, and in the amphitheatre where the air handling unit (AHU) fitted with a CO2 sensor provides the dual function of ventilation and heating when occupied. Two other AHUs are installed to ventilate the premises, in addition to mechanical ventilation in the toilets and other rooms with specific pollution under negative pressure. The digital tech. classrooms are designed so that air is blown into the room and extracted to a technical cabinet, which helps to keep the air circulating and directs the servers’ heat loads into the extract ventilation. There is no active cooling except in the control room of the filming and recording studios where the internal heat gains are highest. Cooling is provided by refrigeration units with heat recovery to enhance the thermal energy of refrigeration units.
  • Technical buildings management has been set up, in order to monitor, plan and control the production equipment and terminal facilities, monitor consumption and interact with users (display in the lobby)

Operation & Maintenance: site maintenance for the next 25 years has been entrusted to Eiffage teams, allowing for excellent responsiveness in the event of requests for assistance from users. The cost of this service is included in the total rent paid by UBL. The amount was calculated using an overall cost calculation and numerous discussions between the designer and the operator

Visual comfort: 100% of the rooms for prolonged/special use have access to daylight and outside views. Thanks to this architectural design, as well as the choice of pale flooring, walls and ceilings, the premises are very bright, which is already appreciated by current users.

Air quality: For the well-being of future occupants, all materials that come into contact with the interior air are class A or A+ to ensure healthy air in the building

Hygrothermal comfort: the premises are equipped with radiant heaters with certified static thermoregulation that helps to regulate the temperature in each room in a more sophisticated way.

The integration of buildings into their environment:

  • The buildings only offer a few parking spaces for light vehicles in order to promote the use of public transport. Plenty of storage has been installed for bikes and the sites are connected to bike paths. All buildings are on a public transport route like the bus in Brest, and by 2018 there will no longer be a single university building in Rennes that can’t be reached by metro.
  • To ensure pleasant views from neighbouring buildings, the roofs are vegetated and technical equipment is placed in a sort of “golden box” to make it disappear in the building’s architecture.


A study of overall cost has identified the most beneficial technical solutions in the context of the building’s future operation. The buildings have been subject to air permeability testing and reach a Q4 of up to 0.51 m3/h.m² and a RT2012 level of 50%. The project located on the campus of Rennes Beaulieu is competing in the Green Building Solutions Awards 2016logogbsawards2015
