Energy-intensive building

A 100m long building evoking the silhouette of a ship's bow and configured as a training ship, will accommodate 650 pupils / year. It has 7 levels on almost 10 000 m². This project was carried out by Sogea Nord Ouest, a subsidiary of VINCI Construction France.

Owner approach of sustainability

Sustainable Development is a theme that the CODAH is already looking to integrate, with exemplary approaches to project management. With the construction of the ENSM, many environmental parameters have been optimized, such as the environmental footprint (Carbon Footprint), energy autonomy (SMART GRID ready building). In particular, the autonomy of the building in resources has been particularly thorough until achieving a high environmental performance, through the exploitation of solar and maritime renewable energies. The use of seawater for cooling (via the geocooling process) and the heating of the building (via a heat pump with high energy efficiency on seawater) is a special feature of this project. This results in a building whose energy balance is positive, mostly thanks to the implementation of a photovoltaic roof.

Architectural description

The pupils are immersed in open sea conditions closest to the real world, including machine simulation rooms, a marine engine and a dozen 'walkway' simulators distributed over three levels. The architectural bias of AIA is to consider the whole school in the spirit of a "school ship". The whole structure is thus configured: from its forecourt to the gangway of embarkation until the ascent to the upper deck through the engine room, the technical rooms located in hold, the sixteen rooms and Four amphitheatres overlooking the basin. Beyond the specific spaces of the program, the different interior spaces are treated in the spirit of those of a ship where the presence of the technique is everywhere visible and omnipresent.

    The Heat Pump features:
    - a base and a supporting structure made of hot-dip galvanized steel sheet
    - a control cabinet with a main disconnect switch (according to EN60204-1 /
    IEC204-1)
    - a CLIMAVENETA W3000 microprocessor controller with dry contacts: On / Off and
    Synthesis of defects + screen interface
    - 2 semi-hermetic screw compressors with power modulation of 50 to 100% or 3
    (50, 75 and 100%). These compressors are equipped with de-oiler, suction valve,
    Discharge and a heating resistor crankcase.
    - of 3 R134 exchangers / multitubular water
    · An evaporator, which makes it possible to produce the refrigerating energy
    · A condenser (called RECUPERATOR in the supplier data sheet), which allows
    To produce calorific energy
    · An exchanger (called the CONSENT in the supplier data sheet), which allows
    To evacuate the surplus calorific or refrigerating energy (via a valve 3
    Modulating channels).
    These 3 heat exchangers are equipped with a differential pressure switch, thermally insulated and equipped with
    electrical resistance.
    - a MODBUS communication card for communication with the GTC
    - flow controller on each exchanger

Urban environment

Having placed the ENSM near the port of Le Havre is an asset for the quality of the education provided. In addition, a shopping center and restaurants close to the school participate in the animation of student life.
