So far transparency is the most important trend developed in the 80s' influencing up to nowadays, and the main way for architecture to innovate. The adjective ``light`` has taken on more and more importance over the last few years in the cultural and market fields and in architecture has almost coincided with the new trends of transparency. One risk is that transparency generates high-tech architecture to hide lacking of original ideas, as it generally occurs when there is not any authentic relationship between form and function, when all reference parameters are lost: the shell being empty and meaningless; spatial hierarchies disappear; the parameter of the genius loci changes completely, the specific role of a building. Along the dictatorship of transparency, seduced by high-tech systems, the facade, the skin, the facade, the skin, becomes much more important than the container itself.
