Construction of the new Lycée Professionnel Maritime (Professional Maritime Highschool) Florence Arthaud in Saint Malo, on the development zone Croix Désilles north-east of the city. Positive energy building. Design according PassivHaus criteria. The property will welcome about 300 students in initial training, it will have a boarding an estimated capacity of 112 beds and a 300 meals catering service. The main goals and challenges ofthe project are:
- Develop the trianing offer of the highschool,
- Increase capacity in initial training and continuing education,
- Provide students and staff with quality equipment,
- Build a High School meeting the coming evolutons of education,
- Achieve exemplary building in terms of sustainable development in the sense of "eco-repository" of Brittany.
Sustainable development approach of the project ownerEco-referential in Brittany.
Eco repository schools confirms the strength of the commitment of the community to Sustainable Development: The development of “eco standard” was piloted by a committee chaired by elected representatives. It is the result of extensive consultations with experts, representatives of the various users of high schools, and regional technical officers in charge of building maintenance sites. More than thirty people were involved in its preparation. With a high level of demand, “eco repository” presents specific, quantified commitments grouped into four thematic issues:
- The preserving users’ health in buildings by the quality of air, water, the choice of materials ...
- The reduce of energy consumption in buildings and renewable energy production ...; la reducing the environmental impact of facilities requiring more efficient water management, more efficient processing of building waste and activity, the preservation of biodiversity, differentiated management of green spaces ...
- The optimization operation and maintenance of buildings. Eco repository includes all the requirements of Brittany, for the most environmentally friendly schools. These four main issues are available through two framework documents. The first is on “eco-design”. The second is ”eco management” of the premises. Thus, “the repository eco” integrates all stages of school life, from design premises in their operation and maintenance.
Architectural descriptionVolume of wood in justifying class 2 of the Decree of 15/03/2010, corresponding to > 44 dm3 SHON
For the boarding: There will be a mixed structure with concrete slab in the central part of the massive building and wood flooring on both side of this central core (intermediate floors R + 1 and R + 2). KLH (wood reference) will be apparent in the boarding room of the ground floor; upstairs, it will be hidden by a false ceiling.
For externship: part of the intermediate floors of R + 1 are provided in alveolar slab (kitchen area, canteen & technical workshops); other floors are laid in solid wood.

The school is located on the town of SAINT MALO. SAINT MALO is a French commune located in Brittany in the Ille-et-Vilaine department, and the main port of the northern coast of Brittany. The tourism sector is also highly developed. High School was built in the northwest sector of the city, at the interface of the dense urban areas and farmland, this is an area combining several functions: crafts, trade and services, education (IUT and college) and sports. Because of its diversity, the built environment is very heterogeneous as the template by the architectural forms of buildings. The area is served by two county roads: one belt agglomeration and the other leading to the city center.
