Woodeum and BNP Paribas Real Estate are developing the Nanterre - La Défense Arboretum close to Nanterre-Université station. This is a new concept for ecological offices built of timber in a large, 9 ha park on the banks of the Seine. Designed by architects François Leclercq and Laisné-Roussel, the 125 000 m² campus, built entirely with a timber structure, aims to become the largest tertiary-sector campus of this type in Europe.
An ecological alternative to high-density development, the innovative architecture of the 4 to 7 storey buildings provides wide terraces on each floor and exceptional views over a 6 ha interior park and the Seine.
The environmental and energy performance of the buildings is exceptional and they aim to obtain the following certifications:
- HQE 2015 Exceptional
- BREEAM 2016 Excellent
- WELL Core&Shell
- Effinergie +
- BBCA low-carbon building / E+C-
- BiodiverCity
The project's environmental ambitions are exemplified in particular through the programme's small carbon footprint due to its CLT structure (pillars, beams and floors) and its low energy consumption levels.
Wood is at the heart of the project, not only in terms of its structure but also its exposed ceilings. Arboretum makes extensive use of renewable energy: solar panels are installed on the roofs and geothermal energy can cover 75% of the project's heating and air conditioning requirements.
The campus also aims to provide a link between the city and the Seine thanks to the development of its 9 ha park which will encourage biodiversity and water infiltration.
