Primary energy need
(Calculation method : RTAA DOM 2016 )
Construction of a school group of 12 classes (5 nursery classes, 7 elementary classes). As well as the associated external spaces. The program of this operation provides in total:
1.676 m² of built-up area
345 m² of sheltered surfaces (pre-school and two-wheeled shelter)
1,680 m² of exterior surfaces.
The project will be part of a sustainable development approach. HQE certification will not be sought. The designers must at least comply with the recommendations of the PERENE tool. The Employer wants the school to deliver a positive energy balance (that produces more energy than it consumes). Environmental design must be able to be used pedagogically by teachers.

Sustainable development approach of the project ownerA bioclimatic architecture that structures the organization of volumes and the technical choices of the project. The founding choices for bioclimatism and technical management of energies are in particular: - the protection of the prevailing winds in the East and South-East sector and the protected organization of primary and especially nursery schools (pergolas and fences) - the definition of a large unit roof umbrella and parasol reinforcing the solar and climatic protection of indoor and outdoor spaces, - surfaces of preals superior to the program, but offering a great comfort of use, in opposition to the courses exposed and on heated. - Reflective and specific sun protection for each case of bay orientation - the choice of a "dry" architecture with wooden framework, allowing the optimized installation of the passive comfort tools, and a pertinent answer to the questions of hygrothermal comfort - The general organization of the rooms allowing an optimized through ventilation - Management of rainwater infiltrated on the plot by valleys and ditches and drainage embankments - The importance of creating quality and well-kept gardens, providing hygrothermal comfort, visual comfort and dust filtration. - quality gardens and care, bringing thermal comfort (the role of "natural air conditioning" trees is no longer to be demonstrated), visual comfort and filtration of dust. - The optimization of electrical devices (limiting the climate in kitchens, efficient lighting, efficient fans ...) makes it possible to build on a projected energy consumption of 18 KWh / m² / year, which is well below the objectives of the Grenelle. The technical elements of the concept are part of the philosophy of the project, the comfort of the project being played on the quasi absence of materials with high inertia (concrete, coatings) replaced by materials without inertia: derived from plaster, wood etc., To optimize the comfort of the premises. The solar protections bathe the living spaces in a light of comfort while generating a general hygrothermal comfort for the operation. The architectural project is inseparable from the technical project and in the present case comfort requires a fundamental reflection in order not to build "banally"
Architectural descriptionA school with two differentiated inscriptions, one protecting the spaces to cover them with a unifying shade, is the space of the small ones, the other opening its courtyards and its preals around and under the buildings, protected by Their vegetal setting forming a frontier with respect to the prevailing winds of the eastern sector, is the space of the primary school. A minimal upheaval of the site is carried out which makes it possible to limit the impact of the project on the territory. The project proposes a very sober volumetric impact deployed using best the effects of site and natural slopes, slightly embedded upstream and on piles downstream.
