The material covered in this book on cogeneration and district energy systems, as well as their modeling, analysis and optimization, is summarized. Several closing remarks are provided, highlighting key points raised in the book that readers should be aware of and take into account in designs and applications of cogeneration and/or district energy systems. The closing remarks also draw on the insights of the authors and include the advantages of cogeneration and district energy systems over conventional heating and cooling systems in terms of factors such as efficiency, reliability and safety, reduced environmental impact and economics. The importance is emphasized of modeling activities, including characterizing configurations and components of cogeneration and district energy systems, analysis based on thermodynamic, economic and environmental factors, and optimization using appropriate objective functions and constraints. Finally, the authors speculate on future issues and considerations relating to the topics covered in this book, based on material included in this book and in the literature as well as their own insights and views. This includes views on the significant likelihood of increasing use in the future of systems that integrate district energy systems with cogeneration plants for electricity and heat, due to the significant technical, environmental and economic benefits.
