Description

Energy Management Principles: Applications, Benefits, Savings, Second Edition is a comprehensive guide to the fundamental principles and systematic processes of maintaining and improving energy efficiency and reducing waste.

Fully revised and updated with analysis of world energy utilization, incentives and utility rates, and new content highlighting how energy efficiency can be achieved through 1 of 16 outlined principles and programs, the book presents cost effective analysis, case studies, global examples, and guidance on building and site auditing.

This fully revised edition provides a theoretical basis for conservation, as well as the avenues for its application, and by doing so, outlines the potential for cost reductions through an analysis of inefficiencies.

  • Provides extensive coverage of all major fundamental energy management principles
  • Applies general principles to all major components of energy use, such as HVAC, electrical end use and lighting, and transportation
  • Describes how to initiate an energy management program for a building, a process, a farm or an industrial facility
