The challenge of the architectural design is to create a bioclimatic structural shell that will ensure the building is permanently in the shade, that favours natural ventilation, cooling, and lighting, recycles water from the roof and shaped surfaces for irrigation, fosters collegiality, healthy competition and promotes the idea of “fair play,” uses natural structural recyclable materials guided by the triple methodology of sustainability principles, enriches the existing Mediterranean flora of the Grove, and finally, it is integrated to the global network of sustainable constructions by minimising its ecological footprint while simultaneously increasing its positive impact on the environment. A total of 2.000 m3 of wood is required for the construction of the arena, which equates to 1460 mature trees from certified, sustainably managed forests, with the result that approximately 50 corresponding projects can be produced per day according to the growth rates of forests in Greece.
