“…The EMS can record energy use with its trending capability. However, most EMSs record "change of value" (COV) event recordings that are not directly used for calculating energy savings without tracking time intervals between individual COV events (Claridge et al 1993, Heinemeier andAkbari 1993). It is possible to tighten COV limits in order to force the trending towards more regular intervals, but this can overload systems which are not designed for such data densities.…”

Quality (IEQ) Issues Volume III Applications Volume I defines basic terminology useful in the M&V field. It defines general procedures to achieve reliable and cost-effective determination of savings. Such definitions then can be customized for each project, with the help of other resources (see Chapter 1.4 and Chapter 6.2). Verification of savings is then done relative to the M&V Plan for the project. This volume is written for general application in measuring and verifying the performance of projects improving energy or water efficiency in buildings and industrial plants. 1. Although there is some debate over the differences between the two terms energy conservation measure (ECM) and energy efficiency measure (EEM) they have been used interchangeably in this document. 2. The terms in italics are defined in Chapter 6.1 The IPMVP has broad application for businessmen, energy managers, law makers and educators and could become the national standard document for M&V. It has been important in helping the growth of the energy efficiency industry in Ukraine. North America's energy service companies have adopted the IPMVP as the industry standard approach to measurement and verification (M&V). "You cannot manage what you do not measure"-Jack Welch, CEO of General Electric When firms invest in energy efficiency, their executives naturally want to know how much they have saved and how long their savings will last. The determination of energy savings requires both accurate measurement and replicable methodology, known as a measurement and verification protocol. The long-term success of energy and water management projects is often hampered by the inability of project partners to agree on an accurate, successful M&V Plan. This M&V Protocol discusses procedures that, when implemented, help buyers, sellers and financiers of energy and water projects to agree on an e) Increase public understanding of energy management as a public policy tool By improving the credibility of energy management projects, M&V increases public acceptance of the related activities. Such public acceptance encourages investors to consider investing in energy efficiency projects or the emission credits they may create. By enhancing savings, good M&V practice also brings IPMVP is complemented by the work of the American Society of Heating, Refrigeration and AirConditioning Engineers (ASHRAE) in the form of its draft Guideline 14P Measurement of Energy and Demand Savings. In contrast to the ASHRAE document, which focuses at a very technical level, the IPMVP establishes a general framework and terminology to assist buyers and sellers of M&V services. ASHRAE's Guideline 14 has completed its first public review and hence was available publicly for a period in the middle of 2000. The

Purpose and ScopeThe International Performance Measurement and Verification Protocol (MVP) provides an overview of current best practice techniques available for verifying results of energy efficiency, water efficiency, and renewable energy projects. It may also be used by facility operators to assess and improve facility performance. Energy conservation measures 1 ( ECMs 2 ) covered herein include fuel saving measures, water efficiency measures, load shifting and energy reductions through installation or retrofit of equipment, and/or modification of operating procedures.The IPMVP is not intended to prescribe contractual terms between buyers and sellers of efficiency services, although it provides guidance on some of these issues. Once other contractual issues are decided, this document can help in the selection of the measurement & verification (M&V) approach that best matches: i) project costs and savings magnitude, ii) technology-specific requirements, and iii) risk allocation between buyer and seller, i.e., which party is responsible for installed equipment performance and which party is responsible for achieving long term energy savings .Two dimensions of ECM performance verification are addressed in this document:• Savings determination technique using available data of suitable quality.• Disclosure of data and analysis enabling one party to perform saving determinations while another verifies it. Structure of IPMVPBased on extensive user feedback, this version provides greater internal consistency, more precise definition of M&V Options, and treatment of additional issues, described below. Additional guidance is provided on how to adhere to the IPMVP. Volume II reviews indoor environmental quality issues as they may be influenced by an energy efficiency project. It focuses on measurement issues and project design and implementation practices associated with maintaining acceptable indoor conditions under an energy efficiency project, while advising on key related elements of M&V and energy performance contracts . Volume II is scheduled for publication concurrently with Volume I.Volume III is planned for publication in early 2001, and reflects guidance and input of over 100 international experts. It will review application specific M&V issues. It is intended to address M&V specifics related to efficiency projects in industrial processes, new buildings, renewable energy, water efficiency, and emission trading. This volume is expected to be an area of continued development as more specific applications are defined. New TopicsIPMVP 2000, in three volumes, introduces new topics of M&V for maintaining building indoor environmental quality (Volume II) and for renewable energy projects (Volume III), as summarized below.Indoor Environmental Quality -Many building energy conservation measures have the potential to positively or negatively affect indoor pollutant concentrations, thermal comfort conditions, and lighting quality. These and other indoor environmental characteristics, which are collectively referred to a...

“…monitoring. An example of this is the monitoring and control system installed at the steam plant at Texas A&M. Because of the availabiiity of highly educated and inexpensive engineering students, much of the system could be custom designed (Heinemeier and Akbari 1993). Connection to site: An advantageous geographical or organizational connection to site can be beneficial in a monitoring project.…”

“…To carry out this investigation, the Energy Managers and Maintenance Supervisors at all three sites were interviewed, and the EMCS manufacturers were contacted to obtain as much information as possible about the systems. Discussion of this analysis can be found in Heinemeier and Akbari (1993). Again, this study was sponsored by the Texas Governor's Energy Management Center through Texas A&M University, and also by the Department of Energy.…”
