This newly revised practical desk reference for energy engineers has been updated and expanded throughout with new chapters on water efficiency and feedback and behavior in energy management. Additional new topics include regression, using energy consumption signatures as an operational control, and interval data information. Thoroughly updated topics include compressed air, computer modeling, data center efficiency, measurement and verification, lighting, laundries, HVAC economizer savings and building vacancy along with manufacturing unit operations and calculating savings from automatic controls. This book is designed to serve as a comprehensive resource for performing energy audits in commercial facilities. Although there are no “typical” commercial buildings, the book begins with the premise that when commercial facilities are subdivided into categories based on business type, many useful patterns can be identified which become generally applicable to the performance of an effective energy audit. Hence, discussion of procedures and guidelines is provided for a wide range of business and building types, such as schools and colleges, restaurants and fast food, hospitals and medical facilities, grocery stores, laboratories, lodging, apartment buildings, office buildings, retail, public safety, data centers, churches and religious facilities, libraries, laundries, warehouses and more. All focal areas of the building energy audit and assessment are covered, including building envelope, lighting, HVAC, controls, heat recovery, thermal storage, electrical systems and utilities.

Apple, Audi, Braun oder Samsung machen es vor: Gutes Design ist heute eine kritische Voraussetzung für erfolgreiche Produkte. Dieser Klassiker beschreibt die fundamentalen Prinzipien, um Dinge des täglichen Gebrauchs umzuwandeln in unterhaltsame und zufriedenstellende Produkte. Don Norman fordert ein Zusammenspiel von Mensch und Technologie mit dem Ziel, dass Designer und Produktentwickler die Bedürfnisse, Fähigkeiten und Handlungsweisen der Nutzer in den Vordergrund stellen und Designs an diesen angepasst werden. The Design of Everyday Things ist eine informative und spannende Einführung für Designer, Marketer, Produktentwickler und für alle an gutem Design interessierten Menschen. Zum Autor Don Norman ist emeritierter Professor für Kognitionswissenschaften. Er lehrte an der University of California in San Diego und der Northwest University in Illinois. Mitte der Neunzigerjahre leitete Don Norman die Advanced Technology Group bei Apple. Dort prägte er den Begriff der User Experience, um über die reine Benutzbarkeit hinaus eine ganzheitliche Erfahrung der Anwender im Umgang mit Technik in den Vordergrund zu stellen. Norman ist Mitbegründer der Beratungsfirma Nielsen Norman Group und hat unter anderem Autohersteller von BMW bis Toyota beraten. „Keiner kommt an Don Norman vorbei, wenn es um Fragen zu einem Design geht, das sich am Menschen orientiert.“ Brand Eins 7/2013 „Design ist einer der wichtigsten Wettbewerbsvorteile. Dieses Buch macht Spaß zu lesen und ist von größter Bedeutung.” Tom Peters, Co-Autor von „Auf der Suche nach Spitzenleistungen“
