SUPERFICI IN MUTAZIONE. LUCI E COLORI IN MOVIMENTO NELL’ARCHITETTURA CONTEMPORANEA

In many contemporary architectural projects particular attention in placed on figurative and chromatic significance of the surfaces, to the importance of the texture, of the visual qualities of the external coverings; playing with lightness, transparency and re- flections. Much attention is given to those details that contribute to make architecture live through materials and technologies that cause reactions, interferences and interactions. In fact it is a communicative evolution that manifested itself more rapidly in the 20th-century following the introduction of materials with superior expressive capacities with respect to those tradi- tional materials used by the building industry. A research was conduced with intention oh a possible classifica- tion of the mediatic architectonic surfaces that led to identify two macro-areas on which to intervene, identified as a communicative envelope of the static or dynamic type. Innovative materials and technologies used in the project oh the mediatic envelope were accurately studied in the research, to be mostly traced back to the influence of the hardware and software technologies on the project and on the architectural perception. Chromogenic films, adhesive polychrome coatings or the integra- tion of led systems in metallic fabrics, influence the perception of the envelope through the dynamism and chromaticity of the surface, creating multiple superimpositions o reflexes and images in continuous transformations. One could say that “the sense of contemporary time is the iri- descent, the ineffable, the continuous modification of every thing in something different , that travels on the wings of a butterfly” (F.Leoni, 2001, p.9).
