Energy Management Principles: Applications Benefits Savings discusses the general principles and methods of energy management. The book is comprised of 15 chapters that tackle fundamentals, methodologies, and case histories of energy savings. Chapters 1 and 2 discuss the background of world energy situation. The third chapter covers the general principles of energy management. Chapters 4 and 5 tackle the organization of an energy management program. Chapter 6 examines energy efficiency, and the following chapters deal with the engineering aspects of energy management. Chapters 11 and 12 cover the supplementary analytical techniques, while Chapter 13 deals with assessment and planning. Chapter 14 discusses energy management in future cities, and Chapter 15 presents the synopsis of the book. The book will be of great use to individuals who seek to understand the general principles and methods of energy management.

Craig Smith retired as a President and Chairman, DMJM H+N, a subsidiary of AECOM Technology Corporation, an international engineering and construction management firm. He began as an Assistant Professor of Engineering at UCLA, where he was also the Assistant Director of the Nuclear Energy Laboratory. After UCLA, he cofounded ANCO Engineers, Inc., an engineering consulting firm in Los Angeles, later joining AECOM as the Vice President of Daniel Mann, Johnson, and Mendenhall (DMJM). He subsequently became the senior vice president, executive vice president, and COO. In 1999, he became the President of Holmes and Narver, Inc. He has been broadly involved in the field of energy and power, responsible for design and construction management, tests, and research on most types of electrical generating facilities.
