ISO 50006:2014 エネルギー管理システム—エネルギーベースライン（EnB）とエネルギーパフォーマンス指標（EnPI）を使用したエネルギーパフォーマンスの測定—一般原則とガイダンス | ページ 6

3.1

adjustment

process of modifying the energy baseline in order to enable energy performance comparison under equivalent conditions between the reporting period and the baseline period

Note 1 to entry: ISO 50001 requires adjustments to the EnB when EnPIs no longer reflect organizational energy use and consumption, or when there have been major changes to the process, operational patterns, or energy systems, or according to a predetermined method.

Note 2 to entry: Typically adjustments are made to account for changes in static factors.

Note 3 to entry: Predetermined methods typically reset the EnB at defined intervals.

3.2

baseline period

defined period of time used to compare energy performance with the reporting period

3.3

boundaries

physical or site limits and/or organizational limits as defined by the organization

[SOURCE: ISO 50001:2011, 3.1]

3.4

energy

electricity, fuels, steam, heat, compressed air, and other like media

Note 1 to entry: For the purposes of this International Standard, energy refers to the various forms of energy, including renewable, which can be purchased, stored, treated, used in equipment or in a process, or recovered.

Note 2 to entry: Energy can be defined as the capacity of a system to produce external activity or perform work.

3.5

energy baseline

EnB

quantitative reference(s) providing a basis for comparison of energy performance

Note 1 to entry: An energy baseline reflects a specified period of time.

Note 2 to entry: An energy baseline can be normalized using variables which affect energy use and/or consumption, e.g. production level, degree days (outdoor temperature), etc.

Note 3 to entry: The energy baseline is also used for calculation of energy savings, as a reference before and after implementation of energy performance improvement actions.

3.6

energy consumption

quantity of energy applied

Note 1 to entry: Energy consumption can be represented in volume and mass flow or weight units (fuel) or converted into units that are multiples of joules or watt-hours (e.g. GJ, kWh).

Note 2 to entry: Energy consumption is typically measured using permanent or temporary meters. The values can be measured directly or can be calculated over a specific period of time.

[SOURCE: ISO 50001:2011, 3.7, modified —Notes 1 and 2 to entry have been added.]

3.7

energy efficiency

ratio or other quantitative relationship between an output of performance, service, goods or energy, and an input of energy

Note 1 to entry: Both input and output need to be clearly specified in quantity and quality, and be measurable.

[SOURCE: ISO 50001:2011, 3.8]

3.8

energy performance

measurable results related to energy efficiency, energy use and energy consumption

Note 1 to entry: In the context of energy management systems, results can be measured against the organization's energy policy, objectives, targets and other energy performance requirements.

Note 2 to entry: Energy performance is one component of the performance of the energy management system.

[SOURCE: ISO 50001:2011, 3.12]

3.9

energy performance indicator

EnPI

quantitative value or measure of energy performance, as defined by the organization

Note 1 to entry: EnPIs could be expressed as a simple metric, ratio or a more complex model.

[SOURCE: ISO 50001:2011, 3.13]

3.10

energy target

detailed and quantifiable energy performance requirement, applicable to the organization or parts thereof, that arises from the energy objectives and that needs to be set and met in order to achieve this objective

[SOURCE: ISO 50001:2011, 3.17]

3.11

energy use

manner or kind of application of energy

[SOURCE: ISO 50001:2011, 3.18]

3.12

facility

single installation, set of installation or production processes (stationary or mobile), which can be defined within a single geographical boundary, organization unit or production process

[SOURCE: ISO 14064‑3:2006, 2.22]

3.13

normalization

process of routinely modifying energy data in order to account for changes in relevant variables to compare energy performance under equivalent conditions

Note 1 to entry: EnPIs and corresponding EnBs can be normalized.

3.14

relevant variable

quantifiable factor that impacts energy performance and routinely changes

3.15

reporting period

defined period of time selected for calculation and reporting of energy performance

3.16

significant energy use

SEU

energy use accounting for substantial energy consumption and/or offering considerable potential for energy performance improvement

Note 1 to entry: Significance criteria are determined by the organization.

[SOURCE: ISO 50001:2011, 3.27, modified — Abbreviated term has been added.]

3.17

static factor

identified factor that impacts energy performance and does not routinely change

[SOURCE: ISO 50015:2014, 3.22, modified — Examples have been modified.]
