The new secondary school in Pordenone aims to be a cultural reference spot for the territory, an icon for sustainability and harmony with its context. The building was built in a prefabricated technology, that defines a pattern for the façade, strictly related to the functional layout. The project is designed taking into much consideration the surrounding setting. The exterior spaces create a green filter between the building and the urban landscape, providing the right intimacy for the classrooms and a new park for the city. A sustainable design that extends to the roofing, where tree-lined squares and green technology devices serve to control the interior microclimate. The concept for school is here envisaged as a cultural and sustainable container.
