Valorización de residuos de producción industrial en elementos de cierre de edificios

The work focuses on the formal and functional value of materials for building enclosing elements. They form the skin of the building, giving it an identity and recognizability in which the designer leaves his mark. Closing elements also serve the important function of a filter with the external environment. In recent years, the construction of double facades with metal load-bearing structures and closure panels made of various materials has become widely used as a passive energy-saving systems system. In the perspective of new models of circular economy to which the construction sector will also have to adapt, The work proposes a critical reinterpretation and a rediscovery of tectonics architecture. Tectonics indeed deals with the understanding of the syntax of building components with their dual formal and functional value, eschewing the fashions of the moment based on the search for increasingly surprising formal solutions. The recognition of the essential link between the form and function of the individual building component and the understanding of the role it plays in the construction are necessary conditions for making buildings sustainable. These are obviously not sufficient conditions for the design of sustainable buildings. The other important aspect is the choice of sustainable materials that can no longer be produced and used according to the models of the linear economy with the use of non-renewable raw materials and energy-intensive production processes. We must find alternative solutions to the use of traditional building materials and encourage the practice of valuing waste from other manufacturing sectors through virtuous processes of industrial symbiosis. The work presents as a case study an innovative example of the use of perforated galvanized steel sheets with automated laser cutting in the construction of the double facade of the building of the company Intertronic in the industrial zone of the park technological of Valencia. Sheet metal is the production waste of an industry located a few kilometers away from the construction site that produces metal components for industrial machinery. The building built in 2004 with a project of the Architects Carmel Gradolí and Arturo Sanz received the Prize and recognition Official College of Architects of the Community of Valencia for its innovative and sustainable design. It is an impressive testimony to how the reuse of processing waste can not only contribute to the sustainability objectives of the construction, but it can also be a stimulus for the creativity of designers who can transform the closing elements of the building in works of art.
