This book examines ways of saving energy by using green roofs and facades, solar devices such as building-integrated photovoltaics (BIPV), and thermal solar panels, as components of energy-efficient building envelopes. The author takes an interdisciplinary / multidisciplinary approach to the subject that analyzes several different scientific fields connected to building research—sustainability, sustainable architecture, energy efficiency in buildings, and building envelopes—while approaching other collateral domains, including history, archaeology, botanics, physics, engineering, and landscape architecture. Alternative Envelope Components for Energy-Efficient Buildings will be a welcome resource for researchers, students, and postgraduates in the fields of energy, building materials, and renewable energy, as well as architects, engineers, and specialists in industries related to building products. Looks at the impact of building envelopes on energy usage; Offers readers an introduction to the principles of sustainability; Presents passive and active approaches to using solar devices.
