In October 2017, the municipality of Chauconin-Neufmontiers officially inaugurates the new premises of the Marianne School, an unprecedented educational extension for this town of 3000 inhabitants.
The project is carried out as part of a HQE approach. It meets the BBC (RT 2012) criteria in the context of France's commitments in terms of sustainable development, energy savings and drastic reduction of greenhouse gas emissions, with a focus on comfort and convenience. occupant health and economical management of buildings.
The architectural concept allows a harmonious relationship of the building with its environment: location, volumetry, orientation, compactness, organization.
Good energy management has been favored, the architectural design optimizes energy consumption.
On this project, the environmental targets were achieved with a direct investment from the municipality in the outcome of this ecological approach.
The AMO HQE 2D Score has clearly identified the environmental characteristics of the materials selected for this construction allowing it to improve this target to the technical notation from P to TP.
The set is compact, its volumetry is simple and of great sobriety.
The total cost of the project (building + HVD) is 3,242,000 euros.
Sustainable development approach of the project owner
The Town Hall of Chauconin-Neufmontiers, owner of this extension of the school group, develops a highly environmental policy: it received the "zero phyt'eau" trophy on the public domain. The municipal infrastructure includes a hotel with swallows, a shared hen house, the creation of a sensitive area on 46 hectares. The rehabilitation of rural roads in harmony with the natural ecosystem was awarded with the "Grand Prix of the environment". The waters of the municipality are treated by a purification plant, valuing a local activated sludge sector. Farmers are encouraged to move towards a so-called "reasoned" agriculture with late mowing, flowering meadows ... As a continuation of these initiatives, the City Council has requested HQE certification for the extension of primary school. elementary school group consists of:
- 6 classes
- master's room
- entrance canopy
- lobby
- multi-purpose room-motor
- computer room
- yard
- health
- arrangement
- technical local
The HQE approach was notably supported by the AMO 2D Score, here is the technical detail of the notation obtained:
HIGH PERFORMANCE
- Target 1 - relation of the building to its environment (TP)
- Target 2 - Integrated Choice of Construction Products, Systems and Processes (TP)
- Target 4 - Energy Management (TP)
- Target 3 - worksite with low environmental impact (TP)
- Target 6 - Waste Management (TP)
- Target 7 - maintenance, maintenance and sustainability of performance
- Environmental (TP)
- Target 10 - visual comfort (TP)
- Target 12 - sanitary quality of spaces (TP)
PERFORMANCE
- Target 5 - water management (P)
- Target 8 - hygrothermal comfort (P)
- Target 11 - Olfactory comfort (P)
- Target 13 - Air Quality (P)
- Target 14 - water quality (P)
BASED
- Target 9 - acoustic comfort (performing for the dining room) (B)
Architectural description
This extension of the school group is organized around a plan of mass which frees the circulation around a central artery. The new district of Pré Bourdeau opens with a new facade of glass and painted wood cladding. The primary school is oriented North-West / Southeast, it is organized around a central clearing that separates the service areas in the north and the living areas (classes) in the south. An airlock provides access to the lobby, which in turn accesses the large central corridor serving classes, ancillary rooms and the multi-purpose room. This multi-motricity is the "prow" of the primary school, at the eastern end of the composition, it is oriented both to the forecourt, belvedere to the new neighborhoods and open on the playground. The architectural concept allows a harmonious relationship of the building with its environment: location, volumetry, orientation, compactness, organization.

Apart from an "envelope" eliminating any thermal bridge, the architectural concept is a "prefabricated all-wood concept" that favors a great flexibility of evolution.
Construction and exploitation costs

Water management
Indoor Air quality
- The comfort of winter will be ensured by the optimization of the heating and ventilation systems , the contributions of calories related to the glazed surfaces of the south facade of the school will participate largely.
- Summer comfort will be assured on the south facade by the wide roof overhang, completed by wooden sunshade blades .
Comfort
- As part of the certification, identification of the sources of electromagnetic emission , carried out by an independent BE according to the standard NF EN 50499: the project does not present any equipment supposing to carry out a complementary risk analysis
- Management of lighting on clock guaranteeing safety and energy saving + arrangements made so that the lighting ensuring the signage of the site does not cause nocturnal visual disturbances for residents
- Airborne sound insulation between premises: Performant
- Impact noise level between premises: Performant
- Isolation vis-à-vis external noise: High performance
- Level of technical equipment noise: Performant
- Internal Acoustics: Base
GHG emissions
- 50,00 année(s)
Life Cycle Analysis
- Using wood as the main material of the extension
- Choice as much as possible of biobased materials .
Reasons for participating in the competition(s)
L’extension de 6 classes présentée est la première école certifiée HQE niveau Exceptionnel de France.
Le projet est présenté dans la catégorie « Bas Carbone ». Il met en oeuvre des solutions favorisant les matériaux bio-sourcés, l’utilisation et le stockage des ressources, ou encore l’intelligence artificielle.
Ainsi, la structure et les façades sont en bois, l’isolant utilisé en façades, cloisons, et sur certains faux-plafonds est bio-sourcé. Cet isolant met en avant les circuits court, il est composé de chanvre, plante poussant localement en Seine-et-Marne.
Les ressources naturelles sont au maximum favorisées et mis en avant : implantation bioclimatique (optimisation des apports solaires et réduction des besoins d’éclairage artificiel), gestion de l’eau réalisée durablement (cuve de récupération, toiture végétalisée, noues, parvis en béton poreux), gestion d’éclairage intelligente (détection de présence et détection lumière jour, gradations par zone), système de ventilation mixte performants (ventilation avec récupération de calories en hiver, ventilation naturelle en été, rafraichissement par humidification), limitation des besoins en chauffage.
