ASHRAE GreenGuide: The Design, Construction and Operation of Sustainable Buildings 4th Edition uses an integrated, building systems perspective to give HVAC&R systems designers, architects, building owners, building manager/operators or contractors need-to-know information on what to do, where to turn, what to suggest, and how to interact with other members of a team designing a green building in a productive way. Information is provided on each stage of the building process, from planning to operation and maintenance of a facility, with emphasis on teamwork and close coordination among interested parties. This edition of the book is an easy-to-use reference with information on almost any subject that should be considered in green-building design. The GreenTips found throughout this edition highlight techniques, processes, measures, or special systems in a concise, often bulleted, format. Also, information is provided in dual units - Inch-Pound (IP) and International System (SI) - so that the content is easily applicable worldwide. References and resources mentioned are listed at the end of each chapter for easy access.
