3.1

baseline period

specific period of time used as the reference for comparing with the reporting period (3.19)

Note 1 to entry: Use for comparing energy performance and the calculation of the energy performance (3.9) and of the energy performance improvement action (3.5) .

3.2

consequential effect

indirect energy effect (3.3) or non-energy effect (3.4)

3.3

indirect energy effect

effect on organizational energy performance (3.9) beyond the direct effect of the energy performance improvement action (3.5)

3.4

non-energy effect

effect of implementing energy performance improvement actions (3.5) that is additional to the energy impact

Note 1 to entry: The M&V objective defines to what extent non-energy items that result from energy performance improvement actions are considered.

3.5

energy performance improvement action

EPIA

action or measure or group of action or measures implemented or planned within an organization (3.17) intended to achieve energy performance improvement (3.10) through technological, managerial or operational, behavioural, economical, or other changes

3.6

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.

3.7

energy baseline

quantitative reference(s) providing a basis for comparison of energy performance (3.9)

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

Note 2 to entry: An energy baseline can be normalized for relevant variables (3.18) which affect energy use (3.12) and/or energy consumption (3.8) , 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 (3.5) .

[SOURCE: ISO 50001:2011, 3.6]

3.8

energy consumption

quantity of energy (3.6) applied

[SOURCE: ISO 50001:2011, 3.7]

3.9

energy performance

measureable results related to energy efficiency, energy use (3.12) and energy consumption (3.8)

Note 1 to entry: In the context of energy management systems, results can be measured against the organization's (3.17) 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]

3.10

energy performance improvement

improvement in measurable results related to energy efficiency, energy use (3.12) or energy consumption (3.8) compared to the energy baseline (3.7)

3.11

energy performance indicator

EnPI

quantitative value or measure of energy performance (3.9) , as defined by the organization (3.17)

Note 1 to entry: EnPIs (3.11) could be expressed as a simple metric, ratio or a more complex model.

Note 2 to entry: For the purposes of this International Standard, a quantitative value or measure of energy performance developed by the M&V practitioner (3.15) is referred to as an energy performance metric.

3.12

energy use

manner or kind of application of energy (3.6)

[SOURCE: ISO 50001:2011, 3.18]

3.13

measurement and verification

M&V

process of planning, measuring, collecting data, analysing, verifying, and reporting energy performance (3.9) or energy performance improvement (3.10) for defined M&V boundaries (3.14)

3.14

M&V boundary

organizational, physical, site, facility, equipment, systems, process or activity limits within which energy performance (3.9) or energy performance improvement (3.10) is measured and verified

3.15

M&V practitioner

individual or team that performs measurement and verification (3.13)

Note 1 to entry: The Spanish equivalent is “profesional en M&V” or “experto en M&V”.

3.16

non-routine adjustment

adjustment made to the energy baseline (3.7) to account for unusual changes in relevant variables (3.18) or static factors (3.22) , outside the changes accounted for by routine adjustment (3.20)

Note 1 to entry: Non-routine adjustments may apply where the energy baseline no longer reflects current energy use (3.12) or energy consumption (3.8) patterns, or there have been major changes to the process, operational patterns, or energy systems.

3.17

organization

company, corporation, firm enterprise, authority or institution, or part or combination thereof, whether incorporated or not, public or private, that has its own functions and administration and that has the authority to control its energy use (3.12) and energy consumption (3.8)

Note 1 to entry: An organization can be a person or a group of people.

[SOURCE: ISO 50001:2011, 3.22]

3.18

relevant variable

quantifiable factor that impacts energy performance (3.8) and routinely changes

3.19

reporting period

report period

defined period of time selected for calculation and reporting of energy performance (3.9)

3.20

routine adjustment

adjustment made to the energy baseline (3.7) to account for changes in relevant variables (3.18) according to a predetermined method

Note 1 to entry: ISO 50001 uses the term “predetermined method” to refer to this concept.

3.21

significant energy use

energy use (3.12) accounting for substantial energy consumption (3.8) and/or offering considerable potential for energy performance improvement (3.10)

Note 1 to entry: Significance criteria are determined by the organization (3.17) or the M&V practitioner (3.15) .

[SOURCE: ISO 50001:2011, 3.27, modified — Added “or the M&V practitioner” to Note 1 to entry.]

3.22

static factor
