Owner approach of sustainability

The municipality of Beaucouzé wanted to make available to its sports associations and public / private schools a new sports hall on the site of The Hague. Equipment that aims to reinforce the existing offer (sports plateaus Aubineau site) and anticipate the disappearance of tennis courts Hautes Roches.

Committed to sustainable development, the municipality has integrated several environmental objectives into its program relating to eco-management, eco-construction, comfort and health. Among the priorities: thermal comfort, energy management and maintenance / maintenance as well as the concept of insertion in the site.

From a purely functional point of view, the multisport hall with a free height of 9 meters, allows to host handball competitions at the regional level and adapts to the practice of basketball, tennis, volleyball and badminton . Another room is reserved for basketball only.

Architectural description

Implantation

It was proposed to "sit" the new Sports Hall against the north facade of the aqua playful building Couzé'o. This stake of implantation constitutes a choice of conception and of major integration, namely:

• Strengthen the opening of all buildings of the equipment on the public domain
• Provide an obvious identification of each equipment
• Develop a central landscaped area

Lobby

The foyer is both an essential architectural and functional element. It is the "communicating" volume, open on the public space and the "pivot", at the interface of multi-sports halls , badminton and basketball. It allows to clearly distribute these three major halls, on both sides, while dissociating the sports / public flows.

Consistency with the existing

The proposed architecture is reflected in three pure volumes, articulated around the hall, with coherent and respectful volumes of the buildings COUZE'O (center aqualudique) and DOMINO (room desports).

A first volume, including hall-basket room, facing the main entrance of the site. It is the identifying and federating element with Couzé'o. Federator by under basement shale masonry, in the extension of the facade of Couzé'o.Identifying by the tension of the awning which accompanies the elevation of the hall and thus provides the composition, the dynamic movement of this new Hall.

Kinetic treatment

A second volume, including the multi-sports hall, anchored to the field, opening widely to the north beyond the stands dedicated to the public. This volume accompanies the inflection of the road of the Houssaye at the entrance of town by a kinetic treatment. They are deflectors channeling the natural light in the room, offering by their treatment with variable geometry, the image of the facade in motion.

A third volume, which primarily houses badminton, completes the first two volumes and strengthens the overall composition. The trapezoidal opening energizes the facade and accompanies the visual break of the base with the high defaults treated with colored zinc.

Perennial materials

Perennial materials, with a strong local reference, accompany this architectural design:

• the basement in shale masonry
• the glazed facade of the hall, shades of blue in reference to the color of the logo of the city of BEAUCOUZE
• zinc coating, bark-copper hue.

The evidence of operation

The architectural coherence is also reflected by the rationality, the evidence of the operation. From the forecourt, the lobby immediately serves the two gyms, while offering a broad view of them. The public accesses the stands directly, while the athletes take an access that leads directly to the locker room.

A passive building

With an obvious and dynamic architecture, the durability of the materials, the functional rationality, we propose a passive building. This behavior is achieved thanks to a high-performance envelope, simple radiant heating techniques and intelligent management of air exchange with heat recovery and recovery of external inputs.

Energy consumption

Urban environment

The implementation perfectly completes the development of the Haye site between Couzé'o and the Houssaye road.

Closed to the west under the prevailing winds, the building opens widely on the village side inviting the inhabitants to the collective sport practice.

The project is part of a landscape site open to the south-west to a very gentle hill line, to the south a tree edge provides a "backstage" equipment and spaces Couzé'o. The north and east of the site mark the current limit of urbanization.

The current site presents to date a voluntary composition plan that strongly integrates active modes of travel. Bike paths and pedestrian paths are very present and structuring in the reading of spaces.

Landscapes and tree and grass plantations reinforce this composition. Parking areas are present but not predominant in the perception of the site.

Landscape integration is at the heart of the design process of our project, the composition of the mass plan is based on the scale and structure of the rest of the site to join and complement the overall composition soberly.

The plantations of shrubs punctuate the space departure and other following lines parallel to the axes of composition of the site. The alignment of trees draws a limit to the north that "shelters" the space opposite the road. He leads the way to the building and recalls the south side of the site.
