Energy-intensive building

Located in Argenteuil in the Val-d'Oise, the Simone-Veil School is a new building inaugurated on the occasion of the start of the school year in September 2019, part of the transformation of the Val-Notre Dame district. Built on three levels, this complex has 20 classes from kindergarten to elementary school, several activity rooms and a multipurpose room.

Program : 5,833 m 2

Contracting Authority : City of Argenteuil

Architect : Ville d'Argenteuil Architects

Building in 90% wood construction: Wood Structure CLT design (technique and exposed wood)
Using virtuous design materials (wood insulation, linoleum, local wood, paint algo, etc.)
Energy Design: district heating network connection, CTA turbofan and CO2 sensors, LED lighting
Carbon Energy level (E + C- label) E3C1 with connection to the district heating network

Sustainable development approach of the project owner

Environmental ambitions were the priority for this project. The aim was to forget the image of the old industrial site on which the school group is built by opting for a contemporary architecture, giving pride of place to natural, biobased materials. and low-carbon like wood. From the mesh facades to the posts supporting the courtyard, including the window frames and the building's framework, this virtuous material is omnipresent, which has earned the building the “ E + C” label. - "with an E3C1 level (called" low consumption ").

Today, the schoolchildren and educational staff of the Simone Veil School have the joy of living in a pleasant place to live, which benefits from an atypical appearance and efficient thermal insulation capacities.

Architectural description

Faced with the dual issue of lead time and an eco-responsible construction method, the proposal aims to design the prefabricated structure of the building in solid cross-laminated timber panel (CLT) and timber frame walls (MOB). Among the advantages of this construction technique in wood, many apply to school programs: increased thermal and acoustic insulation, healthy indoor climate, light material and surface gain compared to a traditional construction, is particularly resistant to fires, less finishing if the appearance of the wood is retained (1 section of the circulation wall and the classroom wall on the blackboard side).

Urban environment

Located between Henri-Barbusse and Michel-Carré streets, the school group will help relieve the surrounding schools of Ambroise-Thomas, Jean-Jacques-Rousseau and Anne-Frank. A place to meet the reception needs of the district, where the population to be educated is increasing.

8 nursery classes, 12 elementary (gradual opening over several school years)
2 leisure centers (nursery and elementary)
several activity rooms
catering common to the entire school group, with 2 nursery / elementary canteens
1 playground for kindergarten, 2 for elementary
caretaker's accommodation
multipurpose room, open outside school hours and days for residents of the area
1 service road between Michel-Carré and Henri-Barbusse streets

Reasons for participating in the competition(s)

The key issue - Low carbon and biobased design:

Reducing the carbon impact of energies in use

Inspired by the negawatt approach, energy needs have been reduced, in particular by a high-performance BBC type envelope.
In order to meet the remaining needs, in particular heating and DHW, the building will be supplied by the Argenteuil urban network deployed on the ZAC, mainly supplied by the combustion of household waste, for minimal extraction of fossil energy.
Dual flow air handling units, CO2 sensors and LED lighting.
The equivalent performance level according to the E + C- standard is the E3C1 level.

Reducing the carbon impact of materials

The main asset of the construction is its wooden structure, on almost all the elements (load-bearing walls, floors, facade, staircase). The superstructure is thus a combination of different construction techniques (timber frame walls, CLT, O'portune® floors) depending on technical constraints (wood, linoleum and local wood insulation).
The search for visible coverings (wooden walls in circulation, absence of false ceilings) also contributed to the reduction of the carbon impact linked to the finishing work.
Another notable point is the use of seaweed-based paint, produced in Brittany, Algo, on all painted surfaces.
For a reduction of the carbon impact of 200 kgeqCO2 / m² compared to a “standard” construction, ie a gain of 20% of CO2, or the equivalent of carbon offsetting the emissions of 120 French people over one year.
