This book explores membrane materials as a means of translating natural and renewable resources into a more flexible, dynamic, and reactive architectural skin. It represents the first time that energy-saving design has been addressed systematically in relation to lightweight building systems and tensile membranes. Understanding of the energetic behavior of membranes and foils used as a building envelope is a fundamental theme, as it is the integration of flexible photovoltaics in membranes, as well as the exploitation of water and wind resources. A theoretical, methodological framework for consciously designing the membrane life cycle is presented. The authors cross-cut and combine exploration of climate-based design methodology and life cycle thinking strategies. Both active and passive systems are investigated, referring to alternative productive resources like sun, wind, and water. Case studies are brought forward in the book's second half, highlighting energy lightness for anincreasingly dematerialized architecture and addressing inherent issues. Four main research and development paths are presented, the first two focusing on advancements in façade materials and Photovoltaic systems applicable to membrane architecture, the third referring to fog and dew harvesting and the fourth dealing with the future frontier of flexible transparency and designs for well-being through a passive solar system.

Deals with sustainable design strategies in relation to lightweight construction and membrane architecture Explains the energetic behavior of membranes and foils used as a building envelope Translates the use of natural and renewable resources in the development of a novel kind of architectural skin

Nebojsa Jakica is Associate Professor in Façade Design and Engineering at the Southern University of Denmark. His Ph.D. dissertation, "Performance-Based Architectural Design, Simulation and Optimization of Complex BIPV Façades", addressed the multifunctionality of Building-Integrated Photovoltaics (BIPV), focusing particular attention on the integration of simulations and optimizations in the parametric design processes and tools for achieving Zero Energy Buildings. This dissertation was closely associated with the nationally funded TIFAIN project, as a result of which he co-authored two patents with Prof. Alessandra Zanelli in the field of BIPV. He led the subtask on Design and Modelling of BIPV under International Energy Agency PVPS Task 15 and is a member of multiple international associations dedicated to engineering and architecture, including the EFN, the IASS, and TensiNet. His architectural work in the private sector includes participation in winning bids in numerous international competitions and projects. He currently leads the SDU FACETS research laboratory that promotes interdisciplinary research and education by exploring the integration of Industry 5.0 technologies in a façade domain with a human-centric approach.

Zhengyu Fan is Associate Professor at Xi'an University of Architecture and Technology. After graduating from Shanghai Tongii University with a degree in civil engineering in 2008, he moved to Italy, where he earned a degree Laude in Architecture at Politecinico di Milano in 2010 and
