The Bilbao Arena’s Green Lizard-Like Facade Defends Against the Spanish Sun

There are two parts to the Bilbao Arena, which is open to local residents when there are no sporting activities taking place. The loud enclosed arena is situated further away from the surrounding homes to cut down on noise pollution, while the quieter sports center hovers below. This section is naturally lit  with a large skylight , and different functions are separated with transparent glass to ensure that this light is distributed throughout.
Atypical to this kind of infrastructure, the arena encloses a rainwater harvesting  cistern that mitigates the need to use additional water to irrigate outside. Additionally, local law requires that a certain percentage of the swimming pool water should be “wasted” every day for hygiene purposes. This water is also collected in a cistern that supplies the municipality with fluid to clean the streets of Bilbao. At 30,808 sqm, this incredible sports arena has the potential to gobble up quite a lot of energy, but thanks to ACXT’s clever design, that potential has been nipped in the bud!
