Design and technology for building envelope.
Martina CORRADO Dottorato in Innovazione tecnologica per l’ambiente costruito.
The curiosity towards sustainable architecture and its applications has prompted me to deepen the topic of sustainability in
building in my thesis focusing, in particular, on the relationship between sustainable project and choice of materials for its
implementation . The debate on built environment currently goes increasingly towards research and testing of new technologies
that integrate facilities for the production of “clean energy” and propose innovative systems to build climatic envelope. Start a
research on -Sustainability in architecture- implies draw a portrait of this culture of built starting with the basic concepts and
historical precedent through the tracks that can be found in the world. The underlying theme of projects which propose application
of theoretical research is the relationship between technology innovation for new envelope and design concepts of living.
My attention goes down to an innovatine material to build envelope called ETFE (ethylene-tetra-fluoro-ethylene) : here are some
examples and tchnical information about it.
