3.7

energy performance

measurable results related to energy efficiency (3.6) , energy use (3.10) and energy consumption (3.5)

3.8

energy performance improvement action

EPIA

action or measure (or group of actions or measures) implemented or planned within a project intended to achieve energy performance (3.7) improvement through technological, management, behavioural, economic, or other changes

[SOURCE: ISO 50015:2014, 3.5, modified — “an organization” replaced by “a project”]

3.9

energy savings

reduction of energy consumption (3.5) compared to an adjusted energy baseline (3.4)

Note 1 to entry: Energy savings may be the result of implementation of an action(s).

Note 2 to entry: The energy baseline can be adjusted with routine adjustment (3.20) and/or non-routine adjustment (3.15) .

[SOURCE: ISO 17742:2015, 2.19, modified — added ”adjusted” before “energy baseline”, notes 1 and 2 rewritten]

3.10

energy use

manner or kind of application of energy (3.3)

Note 1 to entry: Characteristics of energy use include, but are not limited to, the purpose of the use, source(s) choice and application.

3.11

energy using system

physical items with defined boundaries (3.2) , using energy (3.3)

[SOURCE: ISO/IEC 13273‑1:2015, 3.1.9, “system” deleted]

3.12

installation and commissioning period

specific period of time during which the EPIA (3.8) is put in place and inspection has been done on the equipment that is installed, including the operation procedures, to ensure that they conform to the design intent of the EPIA

3.13

interactive effect

significant energy result occurring beyond the project (3.16) boundary (3.2) as a consequence of action(s) within the project boundary

Note 1 to entry: When implementing multiple EPIAs (3.8) within one project boundary, correctly identifying and accounting for additive savings is important.

Note 2 to entry: “significant” is decided by the stakeholder.

3.14

Note 2 to entry: The complexity of the interactions among project activities is not necessarily related to the project size.

Note 3 to entry: Energy savings (3.9) is the quantitative result as the project activities bring about reduction in the energy consumption (3.5) of energy using systems (3.11) within the project (3.16) boundary (3.2) .

Note 4 to entry: New project is a project involving an energy using system that has not been installed or commissioned, such that the project cannot be considered and treated as a retrofit.

Note 5 to entry: Retrofit project is a project conducted on an already existing energy using system.
