ISO 50002:2014(R)
Введение
Цель настоящего международного стандарта состоит в определении минимального набора
требований, приводящих к идентификации возможностей для улучшения энергетических результатов.
Энергетический аудит включает в себя углубленный анализ энергетических результатов организации,
оборудования, системы(ем) или процесса(ов). Он основывается на соответствующих измерениях и
наблюдениях за использованием энергии, эффективностью и потреблением энергии. Энергетические
аудиты планируют и проводят для идентификации и приоритезации возможностей для улучшения
энергетических результатов, снижения потерь энергии и извлечения преимуществ, связанных с
экологией. Выходные данные аудита включают информацию о текущем использовании энергии и
энергетических результатах, а также они содержат перечень рекомендаций, касающихся улучшения
энергетических результатов и финансовых выгод.
Энергетический аудит может содействовать энергетическому анализу, а также мониторингу,
изменению и анализу, описание которых дается в ISO 50001, или его можно использовать независимо
от других видов деятельности.
Настоящий стандарт допускает различия в подходах и методах, а также в области применения,
границах и цели аудита, стараясь гармонизировать общие аспекты, связанные с организацией и
проведением аудита, в целях обеспечения большей ясности и транспарентности.
Процесс энергетического аудита представлен в виде простой хронологической последовательности
действий, но это не исключает повторяемых итерационных действий некоторых шагов.
Основной текст настоящего стандарта охватывает общие требования и структурные рамки,
характерные для всех энергетических аудитов, и это может быть дополнено эквивалентными
национальными стандартами по аудиту. Для аудита определенных типов объектов, процессов или
оборудования, следует обращаться к соответствующим международным, национальным и местным
стандартам и руководящим указаниям, некоторые из которых приведены в Библиографии.
В настоящем международном стандарте используются следующие глагольные термины:
— термин “ shall” обозначает требование;
— термин “should” обозначает рекомендацию;
— термин “may” обозначает разрешение;
— термин “can” обозначает вероятность или возможность.

энергетический аудит эффективным и надежным инструментом поддержания решений руководства и
средств контроля, обеспечивая информацией, на основе которой организация может повышать свою
энергетические результаты.
Строгое соблюдение этих принципов обеспечивает согласованный подход к эффективному
энергетическому аудиту, позволяющий аудиторам по энергетике, работающим независимо друг от
друга, приходить к аналогичным выводам и заключениям в одинаковых обстоятельствах.
Крайне важно, чтобы аудитор(ы) по энергетике были осведомлены о применяемых требованиях по
охране труда на всем протяжении аудита.
Организация производит отбор аудитора(ов) по энергетике на основе предполагаемой области
применения и границ энергетического аудита, целей аудита и компетентности аудиторов.
4.2 Аудитор по энергетике
4.2.1 Компетентность
Применение следующих принципов аудитором по энергетике является основополагающим условием
для успешной работы в ходе энергетического аудита.
Аудитор по энергетике должен обладать знаниями и навыками, необходимыми для выполнения
мероприятий аудита в установленной области применения энергетического аудита. Компетентность
может быть продемонстрирована путем:
a) подходящего образования, навыков, опыта и/или обучения с учетом местных или национальных
руководящих указаний и рекомендаций;
b) соответствующих технических навыков, связанных с областями использования энергии, областью

Introduction
The purpose of this International Standard is to define the minimum set of requirements leading to the
identification of opportunities for the improvement of energy performance.
An energy audit comprises a detailed analysis of the energy performance of an organization, equipment,
system(s) or process(es). It is based on appropriate measurement and observation of energy use, energy
efficiency and consumption. Energy audits are planned and conducted as part of the identification
and prioritization of opportunities to improve energy performance, reduce energy waste and obtain
related environmental benefits. Audit outputs include information on current use and performance and
they provide ranked recommendations for improvement in terms of energy performance and financial
benefits.
An energy audit can support an energy review and can facilitate monitoring, measurement and analysis
as described in ISO 50001, or it can be used independently.
This International Standard allows for differences in approach and in terms of scope, boundary and
audit objective and seeks to harmonize common aspects of energy auditing in order to enhance clarity
and transparency.
The energy audit process is presented as a simple chronological sequence, but this does not preclude
repeated iterations of certain steps.
The main body of this International Standard covers the general requirements and framework common
to all energy audits that can be supplemented by equivalent national audit standards. For auditing of
specific types of facilities, processes or equipment, refer to the relevant international, national and local
standards and guidelines, some of which are referenced in the Bibliography.
In this International Standard, the following verbal forms are used:
— “shall” indicates a requirement;
— “should” indicates a recommendation;
— “may” indicates a permission;
— “can” indicates a possibility or a capacity.

4 Principles
4.1 General
An energy audit is characterized by reliance on a number of principles. These principles help to make
the energy audit an effective and reliable tool in support of management decisions and controls, by
providing information on which an organization can act in order to improve its energy performance.
Adherence to these principles provides a consistent approach to an effective energy audit that would
enable energy auditors, working independently from one another, to reach similar conclusions in similar
circumstances.
It is essential that energy auditor(s) are familiar with applicable health and safety requirements
throughout the audit process.
The organization selects the energy auditor(s) based on the expected energy audit scope, boundaries,
audit objectives and their competencies.
4.2 Energy auditor
4.2.1 Competency
Application of the following principles by the energy auditor is fundamental to the success of the energy
audit.
The energy auditor shall have the knowledge and skills necessary to complete the defined energy audit
scope. Competence can be shown by:
a) appropriate education, skills, experience and/or training considering local or national guidelines
and recommendations;
b) relevant technical skills specific to the energy uses, scope, boundaries and audit objective;
© ISO 2014 – All rights reserved 3

---------------------- Page: 11 ----------------------

SIST ISO 50002:2017
ISO 50002:2014(E)

c) knowledge of appropriate legal and other requirements;
d) familiarity with the energy uses being audited;
e) knowledge of the requirements of this International Standard, national and local energy auditing
standards;
f) (for a team member designated as lead energy auditor) having the skills to manage and provide
leadership to the energy audit team: a lead auditor should have managerial, professional and
leadership skills in order to manage a team.
NOTE 1 Where there is a single auditor, he/she is considered to be the lead auditor.
NOTE 2 Where a national or local energy auditor certification scheme, or equivalent, is available, certified
energy auditors can be considered. Some schemes can be technology specific.
NOTE 3 The energy auditor is encouraged to demonstrate continual professional development to maintain
and improve auditing knowledge, technical skills and personal attributes. Continual professional development
could be achieved through means such as attendance at meetings, seminars, conferences, technical training, work
experience, self- study, coaching, or other relevant activities.
4.2.2 Confidentiality
The confidentiality of the audit deliverables shall be agreed upon by the organization and the auditor
prior to the start of the energy audit. Energy audit information shall not be used inappropriately
for personal gain by the energy auditor, or in a manner detrimental to the legitimate interest of the
organization.
NOTE This concept includes the proper handling of sensitive or confidential information.
4.2.3 Objectivity
The energy auditor shall act independently and in an impartial manner. Conflicts of interest (personal,
financial or other) shall be identified and disclosed to the organization in a timely manner.
If the organization intends to carry out an energy audit using internal personnel, every effort should be
made to remove bias and encourage objectivity.
4.2.4 Access to equipment, resources and information
For completion of the energy audit based on the defined energy audit scope and boundaries, access is
required to:
a) the organization, facility/facilities, equipment, system(s) and process(es);
b) personnel (engineering, operations, maintenance, etc.), their equipment vendors, contractors and
others to collect information pertinent and useful to the energy audit and analysis of data;
c) other information sources, such as drawings, manuals, test reports, historical utility bill information,
monitoring and control data, electrical equipment panels and calibration records.
4.3 Energy audit
The energy audit shall be conducted according to the following principles:
a) the audit is consistent with the agreed energy audit scope, boundary and audit objective(s);
b) the measurements and observations are appropriate to the energy uses and consumption;
c) the collected energy performance data are representative of the activities, processes, equipment
and systems;

---------------------- Page: 12 ----------------------

SIST ISO 50002:2017
ISO 50002:2014(E)

d) the used data for quantifying energy performance and identifying improvement opportunities are
consistent and unique;
e) the process of collecting, validating and analysing data is traceable;
f) the energy audit report provides energy performance improvement opportunities based on
appropriate technical and economic analysis.
NOTE Appropriate analysis is consistent with the energy audit scope and sufficiently detailed to allow for
effective decision making.
4.4 Communication
The energy auditor and organization shall establish communication channels and methods necessary
to facilitate the audit in a timely manner. Clear lines of communication are essential for the energy audit
team, among the team and with the organization, in a timely manner.
4.5 Roles, responsibilities and authority
The energy auditor(s) and the organization shall determine their respective roles, responsibilities and
authority prior to the start of the energy audit.
NOTE Annex A provides guidance on the typical roles and responsibilities during an energy audit.
5 Performing an energy audit
5.1 General

4 Principles
4.1 General
An energy audit is characterized by reliance on a number of principles. These principles help to make
the energy audit an effective and reliable tool in support of management decisions and controls, by
providing information on which an organization can act in order to improve its energy performance.
Adherence to these principles provides a consistent approach to an effective energy audit that would
enable energy auditors, working independently from one another, to reach similar conclusions in similar
circumstances.
It is essential that energy auditor(s) are familiar with applicable health and safety requirements
throughout the audit process.
The organization selects the energy auditor(s) based on the expected energy audit scope, boundaries,
audit objectives and their competencies.
4.2 Energy auditor
4.2.1 Competency
Application of the following principles by the energy auditor is fundamental to the success of the energy
audit.
The energy auditor shall have the knowledge and skills necessary to complete the defined energy audit
scope. Competence can be shown by:
a) appropriate education, skills, experience and/or training considering local or national guidelines
and recommendations;
b) relevant technical skills specific to the energy uses, scope, boundaries and audit objective;
© ISO 2014 – All rights reserved 3

---------------------- Page: 8 ----------------------
ISO 50002:2014(E)

c) knowledge of appropriate legal and other requirements;
d) familiarity with the energy uses being audited;
e) knowledge of the requirements of this International Standard, national and local energy auditing
standards;
f) (for a team member designated as lead energy auditor) having the skills to manage and provide
leadership to the energy audit team: a lead auditor should have managerial, professional and
leadership skills in order to manage a team.
NOTE 1 Where there is a single auditor, he/she is considered to be the lead auditor.
NOTE 2 Where a national or local energy auditor certification scheme, or equivalent, is available, certified
energy auditors can be considered. Some schemes can be technology specific.
NOTE 3 The energy auditor is encouraged to demonstrate continual professional development to maintain
and improve auditing knowledge, technical skills and personal attributes. Continual professional development
could be achieved through means such as attendance at meetings, seminars, conferences, technical training, work
experience, self- study, coaching, or other relevant activities.
4.2.2 Confidentiality
The confidentiality of the audit deliverables shall be agreed upon by the organization and the auditor
prior to the start of the energy audit. Energy audit information shall not be used inappropriately
for personal gain by the energy auditor, or in a manner detrimental to the legitimate interest of the
organization.
NOTE This concept includes the proper handling of sensitive or confidential information.
4.2.3 Objectivity
The energy auditor shall act independently and in an impartial manner. Conflicts of interest (personal,
financial or other) shall be identified and disclosed to the organization in a timely manner.
If the organization intends to carry out an energy audit using internal personnel, every effort should be
made to remove bias and encourage objectivity.
4.2.4 Access to equipment, resources and information
For completion of the energy audit based on the defined energy audit scope and boundaries, access is
required to:
a) the organization, facility/facilities, equipment, system(s) and process(es);

Introduction
The purpose of this International Standard is to define the minimum set of requirements
leading to the identification of opportunities for the improvement of energy performance.
An energy audit comprises a detailed analysis of the energy performance of an organi-
zation, equipment, system(s) or process(es). It is based on appropriate measurement
and observation of energy use, energy efficiency and consumption. Energy audits are
planned and conducted as part of the identification and prioritization of opportunities
to improve energy performance, reduce energy waste and obtain related environmental
benefits. Audit outputs include information on current use and performance and they
provide ranked recommendations for improvement in terms of energy performance and
financial benefits.
An energy audit can support an energy review and can facilitate monitoring, measure-
ment and analysis as described in ISO 50001, or it can be used independently.
This International Standard allows for differences in approach and in terms of scope,
boundary and audit objective and seeks to harmonize common aspects of energy audit-
ing in order to enhance clarity and transparency.
The energy audit process is presented as a simple chronological sequence, but this does
not preclude repeated iterations of certain steps.
The main body of this International Standard covers the general requirements and frame-
work common to all energy audits that can be supplemented by equivalent national audit
standards. For auditing of specific types of facilities, processes or equipment, refer to the
relevant international, national and local standards and guidelines, some of which are
referenced in the Bibliography.
In this International Standard, the following verbal forms are used:
— “shall” indicates a requirement;
— “should” indicates a recommendation;
— “may” indicates a permission;
— “can” indicates a possibility or a capacity.

1 Scope
This International Standard specifies the process requirements for carrying out an energy
audit in relation to energy performance. It is applicable to all types of establishments and
organizations, and all forms of energy and energy use.
This International Standard specifies the principles of carrying out energy audits, require-
ments for the common processes during energy audits, and deliverables for energy audits.
This International Standard does not address the requirements for selection and evalu-
ation of the competence of bodies providing energy audit services, and it does not cover
the auditing of an organization’s energy management system, as these are described in
ISO 50003.
This International Standard also provides informative guidance on its use (see Annex A).

4 Principles
4.1 General
An energy audit is characterized by reliance on a number of principles. These principles
help to make the energy audit an effective and reliable tool in support of management
decisions and controls, by providing information on which an organization can act in
order to improve its energy performance.
Adherence to these principles provides a consistent approach to an effective energy audit
that would enable energy auditors, working independently from one another, to reach
similar conclusions in similar circumstances.
It is essential that energy auditor(s) are familiar with applicable health and safety require-
ments throughout the audit process.
The organization selects the energy auditor(s) based on the expected energy audit scope,
boundaries, audit objectives and their competencies.
4.2 Energy auditor
4.2.1 Competency
Application of the following principles by the energy auditor is fundamental to the suc-
cess of the energy audit.

Introducción
El propósito de esta Norma Internacional es definir el conjunto mínimo de requisitos para identificar las
oportunidades de mejora del desempeño energético.
Una auditoría energética comprende un análisis del desempeño energético de una organización, equipo,
sistema(s) o proceso(s). Está basada en una medición y observación apropiadas del uso de la energía,
eficiencia energética y consumo. Las auditorías energéticas se planifican y realizan como parte de la
identificación y priorización de las oportunidades de mejora del desempeño energético, reducción del
desperdicio de energía y obtención de los beneficios medioambientales relacionados. Los resultados de
la auditoría incluyen información sobre el consumo y desempeño actuales de la energía y proporcionan
recomendaciones priorizadas para la mejora en términos de desempeño energético y beneficios
financieros.
Una auditoría energética puede servir de apoyo a una revisión energética y facilitar el seguimiento,
medición y análisis, descritos en la Norma ISO 50001, o ser utilizada independientemente.
Esta Norma Internacional permite diferencias en el enfoque y en términos de alcance, límites y
objetivos de la auditoría, y busca armonizar los aspectos comunes de las auditorías energéticas con el
fin de mejorar la claridad y transparencia.
El proceso de auditoría energética se presenta como una secuencia cronológica simple, pero esto no
excluye iteraciones repetidas de ciertos pasos.
La parte principal de esta Norma Internacional cubre los requisitos generales y el marco común para
todas las auditorías energéticas, que pueden ser complementadas por normas de auditoría nacionales
equivalentes. Para auditorías de tipos específicos de instalaciones, procesos o equipos, refiérase a las
normas y directrices pertinentes a nivel internacional, nacional y local, algunas de las cuales están
referenciadas en la Bibliografía.
En esta Norma Internacional, se utilizan las siguientes formas verbales:
— “debe” indica un requisito;
— “debería” indica una recomendación;
— “puede” indica un permiso, una posibilidad o una capacidad;

4 Principios
4.1 Generalidades
Una auditoría energética está caracterizada por que se basa en una serie de principios. Esos principios
ayudan a hacer de la auditoría energética una efectiva y confiable herramienta de apoyo para las
decisiones de gestión y control, proveyendo información sobre la cual una organización puede actuar en
orden a mejorar su desempeño energético.
La adhesión a esos principios proporciona un enfoque consistente para una efectiva auditoría energé-
tica que permitiría a los auditores, trabajando independientemente uno del otro, alcanzar conclusiones
similares en circunstancias similares.
Es esencial que el(los) auditor(es) energético(s) esté(n) familiarizado(s) con los requisitos de salud y
seguridad aplicables a través del proceso de auditoría.
La organización selecciona el(los) auditor(es) basado en el alcance esperado de la auditoría energética,
los límites, los objetivos de la auditoría y sus competencias.
4.2 Auditor energético
4.2.1 Competencia
Es fundamental que el auditor energético aplique los siguientes principios para el éxito de una auditoría
energética.
El auditor energético debe tener el conocimiento y las habilidades necesarias para completar el alcance
definido en la auditoría energética. La competencia se puede demostrar a través de:
a) la apropiada educación, habilidades, experiencia, y/o formación considerando los lineamientos y
recomendaciones locales o nacionales;
b) las habilidades técnicas específicas pertinentes para los usos de la energía, el alcance, los límites y
el objetivo de la auditoría;
c) el conocimiento de los requisitos legales y otros requisitos apropiados;
d) familiaridad con los usos de la energía que están siendo auditados;
e) conocimiento de los requisitos de esta Norma Internacional, y de las normas de auditoría ener-
gética locales y nacionales;

SIST ISO 50002 : 2017

NACIONALNI UVOD

Standard SIST ISO 50002 (sl), Energetske presoje – Zahteve z navodili za uporabo, 2017, ima status
slovenskega standarda in je istoveten mednarodnemu standardu ISO 50002 (en), Energy audits –
Requirements with guidance for use, 2014.

NACIONALNI PREDGOVOR

Mednarodni standard ISO 50002:2014 je pripravil tehnični odbor ISO/TC 301 Upravljanje in varčevanje
z energijo.

Slovenski standard SIST ISO 50002:2017 je prevod mednarodnega standarda ISO 50002:2014. V
primeru spora glede besedila slovenskega prevoda v tem standardu je odločilen izvirni mednarodni
standard v angleškem jeziku.

V Republiki Sloveniji se za izraz "energetska presoja", ki je v standardu SIST EN 16247-1:2012 definiran
v točki 3.1, uporablja tudi izraz "energetski pregled", kot je uporabljen v Energetskem zakonu (EZ-1)
(Uradni list RS, št. 17/2014) in na njegovi podlagi izdanih podzakonskih predpisih.

Odločitev za izdajo tega standarda je v februarju 2017 sprejel Strokovni svet SIST za področja
elektronike, informacijske tehnologije in telekomunikacij.
OSNOVA ZA IZDAJO STANDARDA

– privzem standarda ISO 50002:2014

OPOMBI

‒ Povsod, kjer se v besedilu standarda uporablja izraz "mednarodni standard", v SIST ISO
50002:2017 to pomeni “slovenski standard”.

‒ Nacionalni uvod in nacionalni predgovor nista sestavni del standarda.

SIST ISO 50002 : 2017
Uvod

Namen tega mednarodnega standarda je opredeliti minimalni sklop zahtev, ki bi se uporabljale za
identificiranje možnosti za izboljšanje energetske učinkovitosti.

Energetska presoja vključuje podrobno analizo energetske učinkovitosti organizacije, opreme, siste-
ma(-ov) ali procesa(-ov). Temelji na ustreznem merjenju in opazovanju rabe energije, energijske
učinkovitosti in porabe. Energetske presoje se planirajo in izvajajo kot del identificiranja in prednostnega
razvrščanja možnosti za izboljšanje energetske učinkovitosti, zmanjšanje energetske potratnosti in za
zagotavljanje povezanih okoljskih koristi. Rezultati presoj vključujejo informacije o trenutni rabi in
učinkovitosti ter zagotavljajo rangirana priporočila za izboljšanje energetske učinkovitosti in finančnih
koristi.

Energetska presoja je lahko del energetskega pregleda ter lahko poenostavi nadzorovanje, merjenje in
analizo, kot je opisano v standardu ISO 50001, ali pa se lahko uporablja samostojno.

Ta mednarodni standard dovoljuje razlike v pristopu in glede obsega, mej in ciljev presoje ter uveljavlja
usklajene skupne vidike energetskega presojanja za večjo jasnost in transparentnost.

Postopek energetske presoje je predstavljen kot preprosto kronološko zaporedje, vendar to ne izključuje
ponovitev posameznih korakov.

Glavni del tega mednarodnega standarda zajema splošne zahteve in skupni okvir za vse energetske
presoje, ki jih je mogoče nadomestiti z enakovrednimi nacionalnimi standardi o presoji. Za presojanje
posebnih vrst obratov, procesov ali opreme glej ustrezne mednarodne, nacionalne in lokalne standarde
in smernice; sklici na nekatere od njih so zbrani v poglavju Literatura.

V tem mednarodnem standardu so uporabljene naslednje glagolske oblike:

— "morati, je treba" pomeni zahtevo;

— "naj" pomeni priporočilo;

— "lahko" pomeni dovoljenje;

— "je mogoče" pomeni možnost ali sposobnost.

Energetske presoje – Zahteve z navodili za uporabo

1 Področje uporabe

Ta mednarodni standard določa zahteve za proces izvajanja energetske presoje v zvezi z energetsko
učinkovitostjo. Uporablja se lahko v vseh vrstah ustanov in organizacij ter za vse oblike in rabe energije.

Ta mednarodni standard določa načela za izvajanje energetskih presoj, zahteve za skupne procese
med energetskimi presojami in rezultate energetskih presoj.

Ta mednarodni standard ne obravnava zahtev za izbor in vrednotenje kompetentnosti organov, ki
izvajajo storitve energetske presoje, in ne zajema presojanja sistema organizacije za upravljanje z
energijo, ker so te zahteve opisane v ISO 50003.

Ta mednarodni standard podaja tudi informativna navodila za njegovo uporabo (glej dodatek A).

4 Načela

4.1 Splošno

Za energetsko presojo je značilno zanašanje na številna načela. S pomočjo teh načel postane
energetska presoja uspešno in zanesljivo orodje v podporo odločitvam upravljanja in nadzora, saj
priskrbi informacije, na podlagi katerih lahko organizacija sprejme ukrepe za izboljšanje svoje
energetske učinkovitosti.

Upoštevanje teh načel zagotavlja dosleden pristop k uspešni energetski presoji, ki omogoča
presojevalcem, ki delujejo medsebojno neodvisno, da pridejo do podobnih ugotovitev v podobnih
okoliščinah.

Pomembno je, da je (so) energetski presojevalec(-ci) seznanjen(-i) z zdravstvenimi in varnostnimi
zahtevami, ki veljajo v celotnem postopku presoje.

Organizacija izbere energetskega(-e) presojevalca(-e) na podlagi pričakovanega obsega energetske
presoje, meja, ciljev presoje in usposobljenosti presojevalca(-ev).

4.2 Energetski presojevalec

4.2.1 Kompetentnost

Za uspešno energetsko presojo je bistvenega pomena, da energetski presojevalec upošteva naslednja
načela.

Energetski presojevalec mora imeti znanje in veščine, potrebne za izvajanje energetske presoje v
opredeljenem obsegu. Kompetentnost se lahko dokaže z:

a) ustrezno izobrazbo, veščinami, izkušnjami in/ali usposabljanjem v skladu z lokalnimi ali
nacionalnimi smernicami in priporočili,

b) ustreznimi tehničnimi veščinami, ki so specifične za rabe energije ter obseg, meje in cilj presoje,

c) poznavanjem ustreznih pravnih in drugih zahtev,
8

---------------------- Page: 8 ----------------------

SIST ISO 50002 : 2017
d) poznavanjem presojanih rab energije,

e) poznavanjem zahtev tega mednarodnega standarda ter nacionalnih in lokalnih standardov o
energetski presoji,

f) (za člana skupine, ki je vodilni energetski presojevalec) veščinami za upravljanje in vodenje skupine
za energetsko presojo: vodilni presojevalec naj ima vodstvene in strokovne veščine ter veščine
vodenja, da lahko upravlja s skupino.

OPOMBA 1: Če presojo izvaja en presojevalec, se šteje, da je vodilni presojevalec.

OPOMBA 2: Če je na voljo nacionalna ali lokalna shema za certificiranje energetskih presojevalcev oziroma podoben sistem,
se lahko razmisli o najemu certificiranih energetskih presojevalcev. Nekatere sheme so lahko tehnološko
specifične.

OPOMBA 3: Energetski presojevalec naj bi izkazoval nenehen strokovni razvoj za vzdrževanje in izboljševanje svojega znanja
o presojanju, tehničnih veščin in osebnostnih lastnosti. Nenehni strokovni razvoj se lahko doseže na primer z
udeležbo na srečanjih, seminarjih in konferencah, s tehničnim usposabljanjem, delovnimi izkušnjami,
samoizobraževanjem, mentorstvom ali drugimi ustreznimi aktivnostmi.

4.2.2 Zaupnost

O zaupnosti izsledkov presoje se morata organizacija in presojevalec dogovoriti pred začetkom
energetske presoje. Energetski presojevalec ne sme uporabiti informacij o energetski presoji na
neprimeren način za osebno korist oziroma jih ne sme uporabiti na način, ki škodi legitimnemu interesu
organizacije.

OPOMBA: Ta koncept vključuje pravilno ravnanje z občutljivimi ali zaupnimi informacijami.

4.2.3 Objektivnost

Energetski presojevalec mora delovati neodvisno in nepristransko. Nasprotja interesov (osebnih,
finančnih ali drugih) je treba pravočasno prepoznati in razkriti organizaciji.

Če organizacija želi izvesti energetsko presojo z notranjim osebjem, naj to osebje na vsak način deluje
nepristransko in si prizadeva za objektivnost.

4.2.4 Dostop do opreme, virov in informacij

Za dokončanje energetske presoje na podlagi opredeljenega obsega in meja energetske presoje je
treba omogočiti dostop do:

a) organizacije, obrata/obratov, opreme, sistema(-ov) in postopkov,

b) osebja (inženirjev, operativnega osebja, vzdrževalcev itd.), prodajalcev njihove opreme, zunanjih
izvajalcev in drugih, da se zberejo ustrezne informacije, ki so uporabne za energetsko presojo in
analizo podatkov,

c) drugih virov informacij, kot so risbe, priročniki, poročila o preskusih, pretekle informacije o fiksnih
stroških, nadzorni in kontrolni podatki, plošče električne opreme in poročila o kalibraciji.

4.3 Energetska presoja

Energetsko presojo je treba izvesti skladno z naslednjimi načeli:

a) presoja je skladna z dogovorjenim obsegom energetske presoje ter mejo in ciljem(-i) presoje;

b) meritve in opažanja so ustrezni za rabe energije in porabo;

c) zbrani podatki o energetski učinkovitosti so tipični za aktivnosti, procese, opremo in sisteme;

d) uporabljeni podatki za kvantificiranje energetske učinkovitosti in prepoznavanje priložnosti za njeno
izboljšanje so dosledni in edinstveni;

9

---------------------- Page: 9 ----------------------

SIST ISO 50002 : 2017
e) postopek zbiranja, validiranja in analiziranja podatkov je sledljiv;

f) poročilo o energetski presoji vključuje priložnosti za izboljšanje energetske učinkovitosti, ki temeljijo
na ustrezni tehnični in ekonomski analizi.

OPOMBA: Ustrezna analiza je skladna z obsegom energetske presoje in dovolj podrobna, da omogoča uspešno odločanje.

4.4 Komuniciranje

Energetski presojevalec in organizacija morata pravočasno vzpostaviti komunikacijske kanale in načine
komunikacije, potrebne za izvajanje presoje. Jasna in pravočasna komunikacija med člani skupine, ki
izvaja presojo, ter med njimi in organizacijo je bistvenega pomena za skupino za energetsko presojanje.

4.5 Vloge, odgovornosti in pooblastila

Energetski presojevalec(-ci) in organizacija morata(-jo) določiti svoje vloge, odgovornosti in pooblastila
pred začetkom energetske presoje.

OPOMBA: Dodatek A vsebuje navodilo o tipičnih vlogah in odgovornostih med energetsko presojo.

4) časovnem okviru za izvedbo energetske presoje,

5) merilih za vrednotenje in razvrščanje priložnosti za izboljšanje energetske učinkovitosti,

PRIMER 1: Donosnost naložbe; možen prihranek energije v daljšem časovnem obdobju; stroški življenjskega cikla;
analiza povečanja stroškov pri zamenjavi opreme za energijsko učinkovitejšo opremo.

OPOMBA 2: Priložnosti za izboljšanje energetske učinkovitosti lahko vključujejo koristi, ki niso povezane z energijo.

6) časovnih obvezah in drugih virih organizacije,

7) ustreznih podatkih, ki jih je treba razkriti pred začetkom energetske presoje,

PRIMER 2: Risbe, postavitev obrata, podatki o pretekli porabi energije, fiksni stroški, če so ustrezno preverjeni,
priročniki za opremo in druga tehnična dokumentacija, vključno s planiranimi meritvami in/ali nadzori med
energetsko presojo.

8) pričakovanih rezultatih in obliki poročila,

9) ali naj se organizaciji predloži osnutek končnega poročila, da ga komentira,

a) Energetski presojevalec mora od organizacije zahtevati, da:

1) dodeli osebje za pomoč energetskemu presojevalcu ali skupino, sestavljeno iz članov, primernih
za namen: ti posamezniki morajo imeti potrebne kompetence in pooblastila, da zahtevajo
izvajanje neposrednih dejavnosti na postopkih in opremi oziroma jih izvajajo sami ter podpirajo
opredeljen obseg in cilje energetske presoje;

2) obvesti ustrezno osebje in druge zainteresirane strani o energetski presoji, njihovih vlogah,
odgovornostih, sodelovanju in vseh zahtevah, ki jih bodo morali izpolniti;

3) zagotovi sodelovanje udeleženih strani;

4) potrdi vse nenavadne pogoje, ki lahko vplivajo na energetsko presojo ali energetsko
učinkovitost, npr. vzdrževalna dela, posebne obiske (stranke, regulatornih organov itd.),
pomembne spremembe v obsegu proizvodnje in drugo.

Če energetski presojevalec ni ena oseba, mora biti član skupine za energetsko presojo imenovan
za vodilnega energetskega presojevalca.

OPOMBA 2: Nekatere od teh zahtev so bile morda že izpolnjene v zgodnejših fazah.

b) Energetski presojevalec se mora z organizacijo dogovoriti o:

1) ureditvi dostopa, ki ga energetski presojevalec potrebuje v okviru opredeljenega obsega
energetske presoje,

2) zahtevah za zdravje, varnost in varovanje ter pravilih in postopkih v primeru sile,

3) razpoložljivosti virov, vključno z energetskimi podatki in potrebi po dodatnih meritvah,

4) veljavnih dogovorih o nerazkrivanju (npr. najemnikov v zgradbi),

5) zahtevah za posebne meritve, če so potrebne,

6) postopkih za namestitev merilne opreme, če je potrebna.

Energetski presojevalec mora z organizacijo pregledati podrobnosti plana energetske presoje,
vključno z urniki, procesi, morebitno potrebno opremo za dodatne meritve, intervjuji osebja
organizacije, sestanki, obiski mesta presoje itd.

5.4 Zbiranje podatkov

Energetski presojevalec mora zbirati, združevati in zapisati ustrezne energetske podatke, ki podpirajo
cilje presoje, če so na voljo. To vključuje naslednje informacije:

a) seznam sistemov, procesov in opreme, ki porabljajo energijo,

b) podrobne značilnosti rab energije znotraj opredeljenega obsega energetske presoje, vključno z
ustreznimi spremenljivkami in mnenjem organizacije, kako te spremenljivke vplivajo na energetsko
učinkovitost,

c) pretekle in trenutne podatke o energetski učinkovitosti, vključno s:

1) porabo energije,

2) pomembnimi spremenljivkami,

3) pomembnimi povezanimi meritvami,
