Through an architectural contest, the DTT has set an important and necessary goal to bring all its services in one entity. The chosen site, the complexity of existing planning regulations, the variety of functions which needed to be sheltered make that a particularly interesting project. Future users, the public and professionals who will be received and the surrounding urban fabric will deliver the success of this ambitious project whose ecological vocation is clearly affirmed.
The idea of an intervention '' light '' on the ground took shape, like lifting a piece of paper to slide much parking underneath while releasing a large garden central courtyard, a sort of space around plant which all functions are organized. Therefore, the establishment of buildings in L was obvious, linear buildings crossed by loose '' loopholes '' for natural ventilation on all major corridors. Construction is well away as possible from the noise to make way for a vast landscaped area centered on the entry.
La création de ce parking en demi-niveau permet d’envisager une extension à l’échelle de l’ensemble de la parcelle.
The control of solar and exposure gain to dominant winds help to minimize and optimize the use of air conditioning. For the same purpose, the lobby and the corridors are naturally ventilated. The materials have been chosen according to their energy consumption. It is expected to harvest rainwater to supply the flushing and irrigation of large forecourt plant drip. All waste water will be collected by the sewage treatment plant and processed by rotating biodiscs rejecting the quality of water E, suitable for watering by infiltration and F for discharge into the natural environment.
