This book provides the theoretical background and the practical tools to assess the energy behaviour of different responsive envelope technologies in current and future climate scenarios. Starting from the state of the art of the climate change and of the most innovative responsive technologies, it includes a detailed description of the tools and settings required to run building energy simulations that properly account for the envelope responsiveness in current and future scenarios. The purpose of the book is to help architects, façade consultants, researchers, and students of building engineering and environmental design of buildings to understand, simulate, and consider the emerging responsive envelope technologies as viable solutions to improve the energy consumption and the climate resilience of buildings. Therefore, it bridges the gap between innovative technologies and design practice, providing all the required tools to begin to spread these systems improving the climate resilience of the built environment.
