Geometric patterns and dynamics of foldable moduli for adaptive façades

The design of buildings with a limited environmental impact and improved energy efficiency is nowadays of fundamental importance to face the challenge of reducing pollution and saving natural resources, without giving up comfort, indoor air quality and well-being. In fact, it is well known that the building industry is one of the largest consumers of material and energy resources and, among the many parts that make up a building, façades are responsible for a huge energy exchange with the surrounding environment. Therefore, both the research world and industry are very interested in effective solutions for smart and climate adaptable façades. A variety of concepts and solutions, which are competing with each other, have indeed already been developed. However, the field is not yet mature and an increase in emerging and innovative solutions is expected and requires future research and further challenges to be addressed. Recent studies have paid attention to the mechanics of folding sunscreens made with origami panels activated by stretching or releasing strings, following the tensegrity design philosophy. The present contribution is aimed at promoting innovative technological solutions based on the study of new models for foldable façade modules, paying attention to geometric patterns, deployability and mechanical properties.
