Type of territory

The CNSD site has 50 hectares located in the heart of the forest of Fontainebleau. The Fontainebleau massif, emblematic site in many ways, has joined the European network of Natura 2000 sites because it is home to a particularly rich and diverse fauna and flora, to the point that some scientists consider the forest as the richest in Europe. West. It is home to Europe's richest arthropod fauna (3,300 species of beetles, 1,200 Lepidoptera) and about 60 protected plant species.

Located 60 km south of Paris, 40 minutes by train from Gare de Lyon and 1 hour by car from Porte d'Orleans, this renowned tourist region is a major asset for the organization of any sporting event .

Quality of life / density

Net density

Culture and heritage

ADIM Paris Ile-de-France has proposed a real strategy of respect for the site via a convention of study with the National Museum of Natural History. The Museum's expertise has been used in the dynamics of preserving local fauna, surrounding flora and the development of a sustainable life throughout the project.

Social diversity 

The accommodation areas fall into three broad categories: double or single rooms for trainees and short stays, independent studios for executives and a building similar to a hotel 2 ** for VIP trainees and the generation of ancillary revenue during periods of poor training.

Ambient air quality and health

Natural ventilation of privileged buildings; VOC low-emissivity materials (systematic A + labeling for interior coatings), chemical agents (CMR)

Acoustic comfort (strategic location of car parks and technical equipment); visual comfort (site with high density of green spaces, optimal natural lighting of premises)

Circular economy

Recycling of the products resulting from the demolition:

The original site had a number of dilapidated and unused buildings that were demolished. The demolition waste was then crushed directly on the site and then reused within the VRD lot, especially for roads and filter nets.

Mobility strategy

Management of soft movements, pathways, access and parking

The location of the car parks at the level of the buildings made it possible to facilitate the soft movements, on foot or by bicycle, which were materialized by a clear path. The presence of a pedestrian mall delimiting the central part of the site also contributed to the reduction of on-site vehicle movements.

SOLUTIONS

• Soft transportation
• Parking management

Water management

Integrated and landscaped rainwater treatment systems: Natural valleys were created to recover the rainwater and thus reform the water table under the site. This allows the site to be fed with drinking water. The planned sanitation system is of the separative type: a rainwater network for outdoor and roof spaces, and a wastewater network. The recovery tank located on the roof allows the cleaning of roads or the watering of green spaces. The waterproof surfaces have been optimized and robust plants requiring little watering have also been put in place.

Soil management 

Planted species have notably been used to control invasive plants present on site. Typical species of the forest of Fontainebleau mainly have been planted and robust plants requiring little watering have also been set up.

Waste management

Recycling of demolition products via specialized subsidiaries in the construction phase: To limit the impact of the operation on the environment, the demolition products were recovered by re-use and recycling on site for the realization of the VRDs. In this way, site waste was crushed into recycled concrete and used especially for roads.

Biodiversity and natural areas

The site of the forest of Fontainebleau, where ADIM Paris Ile-de-France proposed a real strategy of respect of the site via a convention of study with the National Museum of Natural History, is classified Natura 2000. The expertise of the Museum has been used in the dynamics of preservation of local fauna species, surrounding flora and the development of a sustainable life.

Faced with the unique and fragile ecosystem of the Fontainebleau forest, the actors were able to carry out a sustainable development policy from the design stage, and at all levels, minimizing the impact of the operation and promoting respect and respect. insertion of the surrounding biodiversity into the development project.

On the other hand, each development carried out was designed with the aim of enhancing the surrounding site. The project focused on the protection and conservation of existing flora and fauna, soil protection, rainwater management on the plot, recycling of materials and the rational use of available space. on the site.

Biodiversity included in the building construction reflection:

Choice of reflected equipment (lighting, pipeline deviation, low construction impact on biodiversity, etc.); decrease in footprint areas

Management of spaces and integration in the site:

Differentiated management of green spaces; respect for the surrounding site; early renewal of the forest; adaptation of the site to the life cycles and habits of the species present

SOLUTIONS

Differentiated management of green spaces

Description :

Two types of grasslands decorate the campus.

The "meadow grasslands" accompany main roads and pedestrian paths. It is a maintained space that can be wooded and shorn twice a month. They offer breakthroughs to buildings and wooded edges. Under the wooded masses, users of the site have the feeling of making their way "through the woods".

The "high meadows" have a natural landscape quality. A "differentiated" type of management reduces the number of clippings and reinforces the natural state.

Buildings

Particular attention is paid to the types of materials used in buildings.

Use of bio-based materials:

The wood used in frontage is durable and perennial. Local species are favored in the case where the local resource is not adapted or non-existent, wood from sustainably managed farms (FSC and PEFC label) are used.

VOC:

Interior coatings and finishing products are systematically selected for their low emissivity with A + labeling.
