Football Training Center | Chartier-Corbasson Architectes

Football Training Center The project is situated between a river (La Selle) and the football pitches: In the northwest, the environment is loosened up to the La Licorne stadium, with which the ground of setting-up is connected by a series of football pitches. In the South is the ground is lined of La Selle which oscillates in the middle of plentiful one wild vegetation. The setting up of a training center has opened up a dialogue between mastered nature, artificially represented by football pitches, and the wild vegetation on the banks of the River Selle. Program The Football Training Center is divided in two parts distributed according to floors: - In the first floor: - the accommodation for 45 trainees, bedrooms and dormitories. - the training and the administration - At the ground floor - cloakrooms, medical unit and services. - the halls of activities such as body-building, games, TV room, catering. The project which we propose is both an answer to the site and to the program. The transcription of the program on the site brought us to conceive a double-sided building, the face on the river receiving program’s elements turned to a more internal life. The football pitch side receives cloakrooms and bedrooms: the building is in the continuity of the football pitch taking back its aesthetics with white lines and with lawn. The cloak of turf is deformed and adapts itself to cover the building. The borders of the plant cover are finely worked, until disappear in perspective Under the coat of lawn, openings of bedrooms emerged, as well as the cloakrooms lightings. No gratings or antenna, technical equipment appears in roof, because of their laterally position. The public entrance is may possible by an 5 % access ramp situated in a fault which goes along the football pitch and offers a sight on this one. The river side receives program elements to take advantage of the surrounding landscape (those where we are brought to stay during prolonged duration: administration, training and, at the ground floor, the body-building and the catering, the relaxation and the TV). The ground floor, very widely glazed lets perceive from the hall the outside vegetation which plays at the same time the role of filter, so protecting the intimacy of the users. A terrace prolongs the catering room to the edge of water, in the middle of a recreated landscape and of movements of ground inferred by the extra height of 50 cm of the building (forced by the Prevention Plan of Floods Risk). Games of reflections and lights are create by the reflecting glazing. The building is innervated in its center by a big space double height, crossed by footbridges, so giving central illumination and an intern distribution of the building. The entire 1st floor is served by stairs with clear way, positioned in the middle of this space. Upstairs, training’s room and the administration are welcomed in exgrowths which come in overhang of the facility taking back the proportions of the neighborhood. Walls of the upstairs’ rooms constitute the structure of the building (sail beam) which allows to cross long ranges, so allowing the creation of the panoramic halls of the ground floor, free of any post. To control the impacts of the project on the outside environment 1- Choose materials and processes of sustainable construction Sustainable materials in the tried quality: some concrete, no paint facade, some steppe black soil, panels of aluminum facade anodized in outside facing on small surfaces. 2 - Reduce loads and functioning costs of buildings > > Climatic Regulation Its vegetal roof favors the climatic regulation of the facility and reduces the energy consumption. The thickness of insulating material is minimized under the vegetable layer. > > Limit the energy consumption. A double performed glazing: Climaplus solarcontrol with filling Argon The outside face is a glazing “Antelio clair” from Saint-Gobain (= semi reflecting) Fluos lightings are for the majority. These are punctually completed by discharge lamps, particularly in the hall, or in the panoramic halls. Doubles flows ventilation was retained limiting needs in heating. > > To reduce consumptions of drinkable water The plant cover allows the water retention, not to overload the neighboring river (La Selle). > > Develop practices of maintenance and sustainable maintenance Spaces in concrete, the Galva steel’s stairs, the panels of aluminum facade anodized do not ask or not enough maintenance. The vegetation of the roof asks only for 2 sheerings a year. > > Prevention Plan of floods Risk - PPRI In regard to the building permit, it was asked to supply a note of adaptation to the “PPRI”. This note was realized by Apave and delivery for the DRIRE (Regional Office of Industry, Search and Environment). The DRIRE based itself on this note to require from the main contractor the creation of retention’s ponds as well as the extra height of the low floor of 50cm with regard to the natural ground. The 50 cm extra height was not a problem, although it would have been preferable that this datum is known from the competition (the prejudice of a project as "embedded" in the landscape become paradoxical with this will of extra height). Reading the PPRI, it seems clear that the retention’s ponds, which have to limit the erosion due to the runoff, are recommended (not even required) in zones very clear and fixed by the PPRI: zones of crests. Our being project places have 3 meters of the river, we did not find how our building could create erosion in bottom of valley. In fact the interest of these ponds of retention appeared to us limited. So we appealed in a hydrologist, who confirm our doubts and even emitted the hypothesis that these ponds of retention would have a negative effect on the environment, by limiting the contribution of water which would have naturally been made into the river. In reply, our hydrologist calculated the power of retention of our vegetal roof, completed by a draining trench in foot of the project. By this calculation, we were able to reduce more than 50 % the size of these ponds of retention (At the end 2x12m3). Finally, rather than to envisage these ponds as simple technical works, they were the object of a certain direction, positioned in the prospect(perspective) of the parking lot and are planted. > > Structure: The structure is entirely in concrete. The most long-range are of 11 meters, above the weights room. To obtain this crossing, we planned sail beams (absence of dropped girder, allowing to not using false ceilings) which form the walls of chambers or 1st level rooms. > > Mounds of earth They do not serve has to retain the water; it is the plant cover which plays this role. Mounds have a role of adorn balls, face has the entrance. CENTRE DE FORMATION AUX METIERS DU FOOTBALL Amiens 2008 Le terrain est situé entre une rivière (la Selle) et des terrains de football : Au nord ouest, l'environnement est dégagé jusqu'au stade de la Licorne, auquel le terrain d'implantation est relié par une série de terrains de football. Au sud est, le terrain est bordé par un bras de la Selle qui oscille au milieu d'une abondante végétation sauvage. De fait s'instaure un dialogue entre la nature maîtrisée, artificialisée des terrains de football, et le coté sauvage de la végétation des bords de rive. Programme Le programme du centre de formation se divise en deux parties réparties selon les étages: - Au premier étage: - l'hébergement pour 45 stagiaires, chambres et dortoirs. - la formation et l’administration -Au rez-de-chaussée -les vestiaires, l'unité médicale et les services. -les grandes salles d'activités telles que musculation, jeux, salle TV, restauration. Le projet que nous proposons est une réponse au site comme au programme. La transcription du programme sur le site nous a amenés à concevoir un bâtiment bi-face, la face sur le bras de rivière recevant les éléments du programme tournés vers une vie plus intérieure. >> Le coté terrain de foot reçoit les vestiaires et les chambres: le bâtiment s'inscrit dans la continuité du terrain de foot, reprenant son esthétique à base de lignes blanches et de gazon. Le manteau de gazon se déforme et s'adapte pour recouvrir le bâtiment. Les bordures du manteau végétal sont travaillées le plus finement possible, jusqu'à parfois disparaître dans la perspective. Sous le manteau d'herbe émergent les ouvertures des chambres, ainsi que les éclairages des vestiaires. Aucune grille ou antenne, appareillage technique n’apparaît en toiture, ceux-ci étant positionnés latéralement. Le public accède par une rampe à 5% située dans une grande faille qui longe le terrain de football et offre une vue sur celui-ci. >> Le côté rivière reçoit les éléments du programme plus à même de profiter du paysage environnant (ceux où l’on est amené à rester durant une durée prolongée : administration, formation et, au rez-de-chaussée, musculation et restauration, détente et télé). Le rez-de-chaussée, très largement vitré laisse percevoir depuis le hall la végétation extérieure qui joue en même temps le rôle de filtre, préservant ainsi l'intimité des utilisateurs. Une terrasse prolonge la salle de restaurant vers le bord de l'eau, au milieu d'un paysage recréé et de mouvements de terrain induits par la surélévation de 50cm du bâtiment (contrainte du PPRI). Des jeux de reflets et de lumière sont crées par le vitrage réfléchissant. Le bâtiment est innervé en son centre par un grand vide double hauteur, traversé par des passerelles, assurant ainsi éclairement central et distribution intérieure du bâtiment. Tout le 1er étage est desservi par un escalier à claire voie, positionné au milieu de ce vide. A l'étage, les salles de formation et de l'administration sont accueillies dans des excroissances qui viennent en débord du bâtiment, reprenant les proportions des habitations environnantes. Les parois des chambres de l’étage constituent la structure du bâtiment (poutre voiles) qui permet de franchir des grandes portées, permettant ainsi la création des grandes salles panoramiques du rez de chaussée, libres de tout poteau. Maitriser les impacts du projet sur l’environnement extérieur 1- Choisir des matériaux et des procédés de construction durable Des matériaux durables à la qualité éprouvée : du béton, aucune peinture en façade, de la terre végétale, des panneaux de façade en aluminium anodisé en parement extérieur sur de petites surfaces. 2 -Réduire les charges et les coûts de fonctionnement des bâtiments >> Régulation climatique Sa toiture végétalisée favorise la régulation climatique du bâtiment et réduit la consommation d’énergie. L’épaisseur d’isolant est minimisée sous la couche végétale. >> Limiter les consommations d’énergie Un double vitrage performant : Climaplus solarcontrol avec remplissage Argon La face extérieure est un vitrage antelio clair de chez Saint –Gobain (= semi réfléchissant) Des éclairages fluos pour la majorité. Ceux–ci sont complétés ponctuellement par des lampes à décharge, notamment dans le hall, ou les grandes salles panoramiques. Une ventilation double flux a été retenue, limitant les besoins en chauffage. >> Réduire les consommations d’eau potable La couverture végétale permet la rétention d’eau, et notamment de ne pas surcharger la rivière avoisinante (Selle). >> Développer des pratiques d’entretien et de maintenance durable Les espaces en béton brut, les escaliers en acier galva, les panneaux de façade en aluminium anodisé ne demandent pas ou peu d’entretien. La végétation du toit ne demande que 2 tontes par an.
