From the architectural point of view, designing buildings that are environmentally responsible makes a lot of sense. From the political perspective, it was a priority to have a project that was the most important infrastructure development of the administration, and also addressed the sustainability agenda. For these reasons, we proposed the first LEED Platinum airport, challenging different aspects, including conception, design, development and construction. The pollution issue was a challenge, given that it comes from the airplanes. We did not want the building breathing from the façade, but rather from the roof. We have 21 mega columns through which the building can breathe, by bring it fresh air from the roof and injecting it inside. Also, another challenge was how to divert the sun in order to capture the natural light required for energetic consumption and reflect the heat in order to reduce the usage of cooling systems.
