PROJECT DATE

OXYGENE

 The Oxygène program is part of the creation of an urban continuity between the new Val d'Europe neighborhoods and the historic town center of Montévrain. To bring this project to fruition, in December 2019 the developer EpaMarne selected the SOGEPROM - YUMAN IMMOBILIER consortium as the winning bidder for the construction of around 100 housing units, thanks to the consortium's focus on usage and an advanced environmental approach, with certification levels well in excess of regulatory requirements.

Designed according to the virtuous rules of bioclimatism, the buildings are constructed using a mixed wood-concrete construction system, and 100% wood on the intermediate building of the project. The building will be awarded the E+C- label, level E3 C2 for the section built entirely of wood, and E3 C1 for the section combining wood and concrete. The entire project will also benefit from BEPOS Effinergie 2017 recognition, achieved through the use of renewable energies: photovoltaic solar panels on the roof and a heat pump. The building will also boast the Effinature label.

For this project, Sogeprom is planning sustainable materials and construction processes with:
A 100% wood building and 3 concrete buildings and wood attics / photovoltaic panels / virtuous rainwater management / biosourced insulation / wood boiler room

Together with its partner ELAN, SOGEPROM is developing a comminssioning system that will enable us to set up permanent control and assessment tools, to ensure that commitments made are honored, and to take corrective action if necessary.

SOGEPROM, a signatory to the "1 building, 1 work" charter, has integrated an acrylic fresco into the heart of this program, created by artist Polar in partnership with Art by Real Venture. The artist opted for a poetic composition, oscillating between figuration and abstraction. Illustrative forms give way to pure geometric shapes, reflecting memories of his travels and his love of nature.

 1. Soil preservation

Importation of topsoil: As the site's soil is of poor quality and contains invasive exotic species (such as Galega officinalis), topsoil is imported to improve soil quality and enable new planting.
Ban on plastics in outdoor landscaping: No plastics will be used in landscaping, with the exception of watering equipment, to avoid soil pollution.

2. Plant heritage development

Choice of plant palette: 90.36% of the species planted are local, and the project does not include any invasive exotic plant species. The plant palette includes meadows, temporary wetlands and wooded areas, contributing to local ecological continuity.

Promoting spontaneous flora: 40% of extensive roof surfaces are dedicated to the development of spontaneous vegetation to encourage urban biodiversity.

Management of Invasive Alien Plant Species (IAES): Measures are taken to control and eradicate invasive alien species present on the site, such as Galega officinalis.

3. Support for local wildlife

Protecting ecological continuity: Although the site does not have any significant ecological continuity on a regional scale, the project aims to reinforce urban tree-covered environments and respect the local blue network by avoiding habitat destruction.

Elimination of the mirror effect: The glass surfaces of the buildings are fitted with blackout elements to prevent birds from colliding with the windows.

Plugging trap cavities: Cavities likely to trap animals are plugged to prevent accidents.

4. Reducing the impact of the project

Reducing light pollution: outdoor lighting is designed to minimize light pollution. Lighting is directed towards the ground, with a color temperature below 2500°K, and is switched off or dimmed at night.

Use of certified wood: The wood used in the project comes from local sources and is PEFC or FSC certified, guaranteeing sustainable management of forest resources.

5. Enhancing skills

Raising awareness among professionals: Project stakeholders were made aware of biodiversity issues and Effinature certification at awareness-raising meetings. An Effinature-certified ecologist accompanies the project to ensure compliance with ecological standards.
