This book is the result of two years of architectural research. Dynamic facades, ventilated, high-tech or traditional composites with new features. This book shows that currently new skins not only act as an isolating element, besides interact with the environment, optimizing energy exchange with the outside. From Germany to Australia or Korea to Colombia, there are many examples that readers can visit with this publication. With international vocation due to bilingual English-Spanish text and a language away from technicalities, this paper aims to show as an "interactive toy" the evolving field of the facades in architecture.
