Abstract

The history of architecture has always been characterized by a continuous run up to the different degrees of translucency of the glass envelope, poised between transparency and opacity. But one of the main limitations of the glass was to never allow the variation of the degree of translucency unless you use shielding systems and jamming. Another big limitation of the glass has always been not to allow a high thermal and energy insulation. Today, thanks to chromogenic or photodynamic materials, ie materials able to change its characteristics of transparency to solar radiation as a function of the variation of physical parameters, the above problems can be solved. The paper, which summarizes a speech given at the Vitrum Energy 2009 Conference in Milan, describes the potential of new materials and researchs in progress at the University of Cagliari.
