The design adopted is aimed at favoring bioclimatization strategies, seeking to take advantage of solar orientation and wind direction to passively improve thermal and lighting comfort. In addition, the organization of the floor plan prioritizes the creation of large spaces that make it possible to carry out the activities provided for in the program of needs with comfort and convenience.
The composition is based on a single, horizontal geometry, which places the main areas – the party room and the gym – at opposite ends. This composition makes full use of cross ventilation, as it allows openings on opposite façades. The layout also allows the two spaces to be used simultaneously, without there being any flow, sound or visual interference between the activities. The programs related to service and support uses, such as storerooms, kitchen, office, toilets and changing rooms, are concentrated in the center of the plan, allowing for the centralization of facilities and service and maintenance access flows.
The structural organization is based on a mesh made up of 8 rectangular trapezoids rotated to form 4 rectangular shapes, arranged in a ribbon, resulting in a grid that intersperses straight and diagonal lines. The modules at the ends differ from the others in that they extend beyond the limit of the original geometry, with the aim of expanding the coverage area at these strategic points. From the grid, the two roofs are arranged, the first composed of concrete vaults that always have a straight side and a diagonal one, and the second, in PTFE, which follows the same reference lines as the first, but has a curvature opposite to that of the vaults, resulting in a dynamic and aesthetically appealing composition. The structure was conceived as a standardized, modular system that uses the repetition of identical, prefabricated parts as a way of making the work viable. The project proposes the majority use of concrete, an economical material, specifying tubular steel, a more common profile, for specific details. This strategy contributes to balancing the costs of the work, guaranteeing technical and financial viability.
Another characteristic aspect of the proposed architecture is the control of solar incidence on the building’s surfaces, which manifests itself both on the roof and on the façades. In an effort to support the proposed bio-air conditioning concept, the project includes a double roof, which allows the vaulted slabs to be shaded while at the same time favoring cross-ventilation between the roof layers. In the same vein, the proposal defines generous setbacks on all façades, creating shaded living spaces, while at the same time shading the façades. Completing the passive cooling strategies, the floor slab is raised off the ground, allowing ventilation underneath. This feature also proves convenient for housing equipment related to the installations and the rainwater storage and reuse system.
