The mission of FEMP is to facilitate the Federal Government's implementation of sound, costeffective energy management and investment practices to enhance the nation's energy security and environmental stewardship. Each of these activities is directly related to achieving requirements set forth in:• The Energy Policy Act of 2005, which established a number of energy and water management goals for Federal facilities and fleets and also amended portions of the National Energy Conservation Policy Act (NECPA).• Executive Order 13423, Strengthening Federal Environmental, Energy, and Transportation Management (signed in January 2007). This set more challenging goals than EPAct 2005 and superseded existing executive orders 13123 and 13149.• The Energy Independence and Security Act of 2007, which further established energy, water, and building commissioning management goals and requirements and also amended portions of EPAct 2005 and NECPA. EISA was signed into law in December 2007. • Executive Order 13514, Federal Leadership in Environmental, Energy and Economic Performance(signed in October of 2009) directs Federal agencies to further address energy, water, and operational efficiency beyond E.O. 13423 with targeted goals and actions.Release 3.0 of this guide provides updates to Release 2.0 in the areas of O&M technologies, equipment performance, and costs. This new release also addresses water use and the impacts that recommended O&M practices can have on water efficiency.Overall, this guide highlights O&M programs targeting energy and water efficiency that are estimated to save 5% to 20% on energy bills without a significant capital investment. Depending on the Federal site, these savings can represent thousands to hundreds-of-thousands dollars each year, and many can be achieved with minimal cash outlays. In addition to energy/resource savings, a well-run O&M program will:• Increase the safety of all staff, as properly maintained equipment is safer equipment.• Ensure the comfort, health, and safety of building occupants through properly functioning equipment providing a healthy indoor environment.• Confirm the design life expectancy of equipment is achieved.• Facilitate the compliance with the above-mentioned Acts and Orders as well as Federal legislation such as the Clean Air Act and the Clean Water Act, as well as expected carbon mitigation legislation.The focus of this guide is to provide the Federal O&M/Energy manager and practitioner with information and actions aimed at achieving these savings and benefits.

This release is an update and expansion of the information provided in Release 1.0 of the Metering Best Practice Guide that was issued in October 2007. This release, as was the previous release, was developed under the direction of the U.S. Department of Energy's Federal Energy Management Program (FEMP). The mission of FEMP is to facilitate the Federal Government's implementation of sound cost-effective energy management and investment practices to enhance the nation's energy security and environmental stewardship. Each of these activities is directly related to achieving requirements set forth in the Energy

PrefaceThis Operations and Maintenance (O&M) Best Practices Guide was developed under the direction of the U.S. Department of Energy's Federal Energy Management Program (FEMP). The mission of FEMP is to reduce the cost and environmental impact of the federal government by advancing energy efficiency and water conservation, promoting the use of distributed and renewable energy, and improving utility management decisions at federal sites. Each of these activities is directly related to achieving requirements set forth in the Energy Policy Act of 1992 and the goals that have been established in Executive Order 13123 (June 1999), but also those that are inherent in sound management of federal financial and personnel resources.Release 2.0 of this guide highlights O&M programs targeting energy efficiency that are estimated to save 5% to 20% on energy bills without a significant capital investment. Depending on the federal site, these savings can represent thousands to hundreds-of-thousands dollars each year, and many can be achieved with minimal cash outlays. In addition to energy/resource savings, a well-run O&M program will:• Increase the safety of all staff, as properly maintained equipment is safer equipment.• Ensure the comfort, health and safety of building occupants through properly functioning equipment providing a healthy indoor environment.• Confirm the design life expectancy of equipment is achieved.• Facilitate the compliance with federal legislation such as the Clean Air Act and the Clean Water Act.The focus of this guide is to provide the Federal O&M/Energy manager and practitioner with information and actions aimed at achieving these savings and benefits.The guide consists of eleven chapters. The first chapter is an introduction and an overview. Chapter 2 provides the rationale for "Why O&M?" Chapter 3 discusses O&M management issues and their importance. Chapter 4 examines Computerized Maintenance Management Systems (CMMS) and their role in an effective O&M program. Chapter 5 looks at the different types of maintenance programs and definitions. Chapter 6 focuses on maintenance technologies, particularly the most accepted predictive technologies. Chapter 7 describes the building commissioning process and how it contributes to effective O&M. Chapter 8 covers the topic of metering and its applications for improved operations and efficiency. Chapter 9 explores O&M procedures for the predominant equipment found at most federal facilities. Chapter 10 describes some of the promising O&M technologies and tools on the horizon to increase O&M efficiency. Chapter 11 provides ten steps to initiating an operational efficiency program. Additional information is provided in the appendixes.O&M Best Practices Guide, Release 2.0 v AcknowledgmentsThis report is the result of numerous people working to achieve a common goal of improving operations and maintenance and energy efficiency across the federal sector. The authors wish to acknowledge the contribution and valuable assistance provided by the staff of the Federal En...
