Efficient energy management and effective conservation procedures have been very important considerations for our society for many years. An oil embargo in the 1970s and early 1980s brought about a new awareness of energy conservation. Because of various factors like loss of tax credits and efficiency standards imposed by the government, public interest dropped considerably in regard to energy conservation. A revival in energy conservation among the general public occurred following the Persian Gulf War in the early 1990s.What does the 21st century hold? Conflicts in the Middle East, high prices for petroleum, and increasing population worldwide will all be significant influences on energy and its conservation. Considerable discussion of climate change, global warming, and increased concerns in regard to our electricity supply have provided motivation for building energy demand to be more flexible. Energy Management and Conservation, Fourth Edition, provides a very practical discussion of how energy can be managed and saved in most types of buildings. This edition not only updates the previous edition but adds updated content concerning energy cost reduction/going green to improve the environment. The authors of this book have written several books that use the systems approach. Through the use of the systems approach, the reader will be able to grasp how different parts of a building fit together to form a unit that uses energy efficiently. This text provides a thorough and practical discussion of the operation of systems that are found in most types of buildings. Each system is discussed with energy management and conservation in mind/going green to save money and improve the environment. There are many ways to manage a building to accomplish efficient energy conservation. Several of the chapters have checklists at the end to summarize ways of conserving energy that relate to the chapter.Important changes in this edition include coverage of governmental requirements from agencies such as Environmental Protection Agency (EPA), United States Department of Energy (USDOE), and American Society of Refrigerating, Heating and Air-Conditioning Engineering (ASHRAE), updated as of 2022 standards. Instrumentation updates include types of sensors and the concept of'smart'devices such as meters. Addition of computer building maintenance management systems and new updates for renewable energy resources are included. Enhancements to existing systems content (such as variable frequency drives for pumps) have been carefully added.

This book explores many fundamental topics in a basic and easy-to-understand manner. It, and the accompanying DC-AC Electrical Fundamentals by the same co-authors, have been developed using a classic textbook – Electricity and Electronics: A Survey (5th Edition) by Patrick and Fardo – as a framework. Both new books have been structured using the same basic sequence and organization of the textbook as previous editions.This book has been expanded to 23 chapters, further simplifying content and providing a more comprehensive coverage of fundamental content. The content has been continually updated and revised through new editions and by external reviewers throughout the years. Additional quality checks to ensure technical accuracy, clarity and coverage of content have always been an area of focus. Each edition of the text has been improved through the following features: Improved and updated text content. Improved usage of illustrations and photos. Use of color to add emphasis and clarify content.

Revised and edited, this new third edition reference covers the full scope of energy management techniques and applications for new and existing buildings, with emphasis on the'systems'approach to developing an effective overall energy management strategy. Foremost in the enhancements to the new edition is content that reflects the emphasis on conservation for'green energy'awareness. Also examined are building structural considerations, such as heat loss and gain, windows, and insulation. A thorough discussion of heating and cooling systems basics is provided, along with energy management guidelines. Also covered are energy conservation measures that may be applied for lighting systems, water systems, and electrical systems. Specific energy management technologies and their application are discussed in detail, including solar energy systems, energy management systems, and alternative energy technologies.• Covers the full scope of energy management techniques and applications for new and existing buildings• Emphasizes a'systems'approach to developing an effective overall energy management strategy• Includes enhanced content that reflects the emphasis on conservation for'green energy'awareness
