Thisdocumentprovides and specifies general methods for quantification of PrES, using measure-based calculation methods, also known as bottom-up or EPIA-based methods[2].Indicator based methods[2]and total consumption based methods [3]are not includedin the scope of this document. 

This documentprovidesgeneral principles for categorisingand choosing the method to be used taking account of the context,targeted accuracy and resources available for quantifying the PrES.It also specifies the conditions for ensuring the quality of the PrES, its documentationand validation. 

It appliesto quantification ofPrESfor any:

type of EPIA,

end-use sector,

energy end-use,

level of aggregationof energy savings,


The stakeholders can be private or public organisations, energy auditors, energy services companies, energy and equipment suppliers, policy makers…

This document considers energy savings from:

an EPIA,

an action plan, program or policy(aggregated energy savings).

An action plan, program or policy can be implemented at different scales (organisation, city, region, country). When the energy savings are first quantified at the level of an EPIA and then aggregated, the energy savings at the level of an EPIA are also known as unitary energy savings.

This document describes how to quantify PrES over a prediction period.It can be used to quantify PrESin terms of primary energy or final (or delivered) energy (as defined in [8]).

This document specifies requirements for establishing, implementing, maintaining and improving an energy management system, and its aim is to enable an organization to follow a systematic approach in achieving continual improvement of energy performance.

This document:

a) is applicable to any organization regardless of its type, size, complexity, geographical location, culture, or the products and services it provides;

b) is applicable to activities affecting energy performance that are managed and controlled by the organization;

c) is applicable irrespective of the types of energy and quantity of energy consumed;

d) does not define specific levels of required energy performance improvement, but requires demonstration of continual improvement by determination of energy performance;

e) can be used independently, or be aligned or integrated with other management systems.

Annex A provides informative guidance on this document. Annex B provides a comparison of this edition to the previous edition, ISO 50001:2011.

This European Standard is one of a series of European Standards dedicated to air-cooled heat exchangers.

— forced convection air cooled refrigerant condensers as specified in EN 327;

— forced convection unit air coolers for refrigeration as specified in EN 328;

— air cooled liquid coolers "dry coolers" as specified in EN 1048.

This standard provides information for assessing and presenting the acoustic emission characteristics of heat exchangers under stationary operating conditions.

This European Standard is applicable to selfstanding forced convection air cooled refrigerant condensers and air cooled liquid coolers "dry coolers" and air coolers.
