The exterior of the building is characterized by greenery, which filters the direct views, giving strength from the inside to the vision of nature through the great glass façades. The whole façade system was conceived through the analysis of exposure and solar radiation and integrated with three glasshouses on the eastern side incorporating vertically moving curtains. These glasshouses are able to process the sunlight, in winter collecting the heat formed within the system; then, when external temperatures are high, they protect the inside, limiting the direct solar exposure on the façade, and creating ventilation within the cavity.
