Built as part of the extension of the head office of the insurance group La Mondiale, this Passive® building can accommodate up to 250 employees.The building is 5 storeys high with a basement, for a total of 5400 m² of built area. The building has a pole / beam structure and the facades are made of timber. On this building site, wooden life bases were also set up. The building is certified passivhaus, HQE and BBC.
Sustainable development approach of the project ownerThe construction of a Passive® Building is part of the overall approach to sustainable development of the La Mondiale Group (signatory of the UN World Pact since 2003), at the occasion of the reunion of the variouscompetence centers in one site. This is a great experiment that is fully integrated in the Corporate Social Responsibility approach the Group AG2R La Mondiale, especially for the scale of the Mons-en-Baroeul site, the first establishment of the group and headquarters of the group.
We wanted to go beyond mere compliance with thermal regulations, by experimenting more efficient and environmentally friendly buildings. And a challenge: to associate employees and neighbors to the project, from design to delivery, so that the installation goes smoothly.
Architectural descriptionTimber and masonry construction, facade with large weatherboarding, wood wool insulation, high vegetated roof holding rainwater, concrete slab, reinforced air tightness in the entrance hall.
Building users opinion
"The building is beautiful, it immediately found its place among the other buildings on the site. However, the technical teams needed a little time to tame it, especially its heating control system which requires a fine setting. The first months have therefore not always been easy. People were sometimes too hot or too cold, depending on the floors and the seasons.
In addition, we made the finding of a slight difference between technical expertise and experienced users. In these cases, dialogue is necessary and everyone must do part of the way: put blinds if employees express that they do not see well their screens, for example .
Once the settings done, the building presented a good level of comfort. We are proud and wish to build on this experience to further develop our environmental policy at the site, making sure to articulate with quality of life at work and the necessary economic performance that characterize AG2R La Mondiale."
Brigitte Villette, Director of Site
If you had to do it again?
Passivhaus demands extreme care during the designing stage but also during construction. The skills of engineers, technicians and companions from Rabot Dutilleul Construction find all their meaning. We would be happy to work on similar other projects of such energy and environmental performance.
