The last phase of the Luminy Campus has been delivered and welcomes its new tenants

Atlante is pleased to announce that the teams of Aix Marseille University have moved into the last building delivered since the beginning of March on the site of the Luminy Campus in Marseille.

A social infrastructure project with energy performance commitments

In April 2016, the Aix Marseille University and the Luscie project compagny made up of teams from Bouygues Bâtiment Sud-Est, Bouygues Energies & Services and Atlante Gestion signed a partnership contracts as part of the restructuring and implementation of energy efficiency work on a set of existing buildings and university spaces on the Luminy Campus site.

The contract includes a number of commitments regarding the quality and thermal performance of the buildings, the implementation of efficient operations, preventive maintenant, as well as raising user awareness of the site’s energy consumption.

The project has been in the operating phase since the end of October 2020, when the last building was delivered by Bouygues Bâtiment Sud-Est teams.

Three university buildings renovated to give the campus a new look

Over a period of four and a half years, Bouygues Bâtiment Sud-Est and its partners carried out renovation and modernization work on more than 33,000 square metres of buildings. This was a real challenge when you consider that the site was occupied by more than 12,000 people every day !

The site can now accomodate its students, researchers, teachers and administrative teams in optimal working conditions Bouygues Energies & Services teams will now begin their 25-years building maintenance mission.

Thanks to this project the Luminy science campus is potisionning itself as one of the leaders in the field of education in its region.

How does methanization work ?

Methanization is a phenomenon that produces biogas energy, through the decomposition and fermentation of organic matter. This natural process is due to the action of micro-organisms that digest organic matter. The digestion occurs naturally in certain environments, for example in marshes.


It can also be reproduced by human action, by heating and stirring the organic matter in hermetic enclosures called digesters with total absence of contact with oxygen. The process must be controlled at all times in terms of temperature and pressure, and lasts from 20 to 40 days. Methanization is used for energy production and sale, and also provides a natural and organic amendment for agriculture: the digestate.

The biogas produced by methanation is a 100% renewable energy, which contains between 40 and 60% methane (CH4) for almost as much carbon dioxide (CO2).

Sociale Infrastructure

Sarthe region

Lead investor in the construction and rehabilitation of four middle schools in the Sarthe region, located in Arnage, Coulaines, Le Mans and Noyen-sur-Sarthe to receive 2,300 students.

The project is in the operation phase since 2019.


The project was subject to carbon assessment. Seeing the results, in end-January 2018, CERTIVA awarded MAINE COLLEGES 72 permanent HQE (high environmental quality) certifications for the “Programme Design” phase for each of the schools. The permanent HQE certification for the “Development” phase was awarded in November 2019 for all the schools.

As of November 2019, MAINE COLLEGES has also been awarded the Effinergie + label. This label testifies to the improvement in the buildings’ energy efficiency in relation to the 2012 Réglementation Thermique (the 2012 Heat Regulation).

Water management

Wastewater is let into the wastewater sewerage systems of the towns concerned.

A rainwater harvesting system is planned for sanitary use, so as to cover 10% of the water requirements for toilet bowls and urinals in the toilet facilities.

Waste management

Implementation of waste segregation.

All materials used in the construction have zero or very low VOC (Volatile Organic Compounds) levels.

Energy efficiency

The schools were equipped with low temperature radiators that require 30% less energy to provide the same thermal comfort given their much larger contact surface with the ambient air.

Ceiling radiant panels that allow a more accurate monitoring of power consumption, have been installed in the canteens.

PV solar panels will be installed horizontally on the roof, covering a total area of 57.12 m2.

The kitchen appliances run on electricity and are equipped with an energy optimiser.


The project complies with contractual commitments in terms of first-time employment, namely 20,000 work hours, and in employing SMBs for which the recruiting rate is 40%.

Asbestos removal and demolition works are carried out during school vacations and the floors are hosed in case of heavy dust.
