Towards Energy-Efficient Buildings: Envelope Technologies and Sustainable Energy Systems examines the intersection of building design and energy systems analysis, paving the way to sustainable, efficient buildings and our communal energy future. This book begins by outlining the major energy challenges for buildings and the fundamentals and opportunities in envelope technology for their increasing the efficiency of their energy systems. Close analysis of various technologies is then carried out, including case studies and demonstrations of impact assessment techniques. The ways in which these technologies interact with energy systems within the building are drawn out and clarified for a range of readers. Finally, detailed guidance on energy system assessment and analysis is provided. Bringing together these two essential disciplines for sustainable living, Towards Energy-Efficient Buildings will support energy engineers, researchers, and students of energy systems in developing technologies for energy-efficient, sustainable buildings.
