The project is based on two fundamental ideas: on the one hand, it develops a management strategy analogous to the millennial agricultural shelf, which provides a series of soft topographic terraces for various and adaptable uses, keeping the maximum existing terrain topography and, on the other, it proposes the construction of a large photovoltaic cover that provides the passive environmental conditions of the inner spaces and at the same time has the function of renewable energy production. As a primary element of land containment, the built body, a compact volume, is available, which saves a slope of 3 meters. Taking advantage of the elevation change, the large roof becomes an essential element for active and passive climate management.
The proposed topographic plan aims to establish a visual and functional connection between all social spaces within the facility, including the internal area (beach and pools) and the external areas, thereby achieving a unified space. This will facilitate a unified access control, ensuring that recreation areas and pools are separated from external areas through the use of embankments and plant beds.
Each of the external areas can be independently accessed and are located at varying elevations. This makes them directly accessible from C/Josep Vicenç Foix, enabling their use throughout the year without requiring the rest of the facility to be open. By effectively privatizing the interior recreation and bathing space from street views, and through the use of naturalized fences and vegetation, the parking and external areas serve as a buffer to the urban grid.
Consequently, excavation of the terrain is minimized through the adaptation of the building to the original topography. The integrated built volume, the layout of the ventilated roof, and the discontinuous nature of its geometry maximizes the flow, creating a large canopy and ensuring a constant air current that removes steam and heat accumulation. The height of the changing rooms promotes a certain stratification that cools them and facilitates the extraction of heat and steam at high levels. In cases where natural ventilation is insufficient, a mechanical ventilation system is projected for the changing rooms in general and the shower area in particular.
The dispersed wooden structure is designed to minimize the use of materials, with highly optimized sections that reduce economic costs. The lattice beams span a significant distance and are supported by a series of pillars that are protected by certified intumescent varnishes. Furthermore, the installation of photovoltaic panels enables the generation of electrical energy. Given its large size, the building itself has a zero consumption rate, generating a surplus throughout the year that can be used to power other municipal facilities, thereby making the construction profitable during the winter months.
