After acquiring 2 hectares of parcels that were formerly composed of scrap yards, the L'OREAL Group's Research & Innovation site is building its new research laboratory, the L6, with a twofold objective: environmental excellence and employee well-being.
Chemists, biochemists or biomechanics will join this new building of 5,000 m² spread over three levels. As a model in terms of innovation, integrating digital in all its tools, the building will be flexible and removable, which will stimulate creativity and improve collaboration.
The building has integrated the HQE label, obtaining on the programming and design phases, the maximum rating of "Exceptional". A BEPOS Effinergie approach is also underway (excluding process needs), and the project has just won the ADEME call for projects for the Negative Carbon Positive Energy (E + C-) experiment. The construction, federated around a low nuisance building charter, was based around a BIM model (3D building). It facilitated the organization of the work of the various trades, but also to better understand the maintenance phases during the operation of the building.
The L6 will produce more energy than it will need for its operation (BEPOS frame, out of process). High-performance passive building, 1,500 m² of photovoltaic panels adorn the roof and the outdoor parking. A wind tree about 9 m high will recover energy through small wind blades and will serve to raise awareness of renewable energy. In the continuity of what we have already undertaken on the site, the waters of activity of the building will be purified by a system of basins planted, the rainwater collected in two hydraulic structures of 350m3 vegetated, and the road water treated by hydrocarbon basins. Rainwater will be used for sanitary water needs, and work is underway to reuse the filtered activity water for the sanitary supplement (winning project France Experimentation). The goal is to meet 80% of these needs.
Biodiversity is not left out, the concept of biophilia settling in the building. All the hydraulic structures are vegetalized thus attracting insects, a "wood edge" established on hill embankment will attract birdlife, and two water spaces will allow odonates and amphibians to settle. At the time of its design, the building had been evaluated by the HQE Performance Biodiversity test with an improvement of the varieties of plant species.
The territorial and social anchoring of the Chevilly-Larue campus is once again being honored. At the level of the green flow, adjoining the building, a wall mural on the theme of sustainable development was produced in collaboration with local stakeholders, and a fence allowing biodiversity to cross has been put in place. Lastly, more than 8,000 hours of social integration were carried out for the construction of the structure.
This L6 project is fully in keeping with the logic of the unifying project, Sharing Beauty With All, which commits the L'OREAL group to reduce its environmental footprint but also in the environmental program of the site monitored as part of its ISO 14001 certification since 2010. The anticipation of environmental works with the construction of the evaluation building, the L5, made it possible to obtain the Environment & Biodiversity Grand Prize for the development of the two projects.

Owner approach of sustainability
Last building built the L5 in 2014: project choice with less soil waterproofing, BBC certification, certification HQE Exceptional (2nd building more efficient 2015, Certivea)
Objective of the new building the L6: to go even further in environmental excellence! - Choice to go to a building in BIM model to facilitate the articulation of different trades during construction, but also for the future maintenance of the building; - Willingness of energy production, and work on the BEPOS pilot approach - Use and reuse the water as much as possible (rain, treated ...) - Continue our territorial anchoring with the use of the municipal heat network - Integrate the building the environment of the site and the landscaping for biodiversity
Sober and timeless building in recall with the last built building Flexible laboratory with removable wall to adapt the spaces to the needs of the collaborators Integration of the building in an eco-campus Luminous building with view from the workstations on the landscaped spaces Landscaping imagined by the landscape architect of the site in coherence with the history of the site and the view since the departmental green flow; Structure of slab lightened with air balloons (-1T of concrete, ~ -87T eqCO2)

Application to BIM D'OR
This new building is part of an urban renewal project for old scrap yards (2ha, total site 7ha). The first building built in 2014, and the latter, the L6 in 2018, were designed integrating a flourishing biodiversity where landscapers, cosmetic gardens and filter basins came to improve the frame of view of employees. This project was awarded in 2015 by ADEME by the Business & Environment Grand Prize in the Biodiversity category. The construction of this new project was evaluated during the experiment for the HQE Biodiversité in 2015, where an increase of the diversity of the environments and the permeability of the grounds had been welcomed. It is juxtaposed with the departmental green flow and a work was done with the landscape architect to include it by the urban landscape. A partnership with the city of Chevilly-Larue has made it possible to create a fresco for sustainable development in order to sensitize our fellow citizens to this theme of the future. The site and the L6 are accessible via the metro line 7 and the Tram T7 reaching the airport Orly. The site has surrendered part of its land to accommodate this important means of transport for so-called "soft" urban travel. A study of all flows in-house was conducted to better anticipate needs (pedestrians, bicycles, vehicles waste, logistics, waste).
