Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: w w w . i s o .org/ iso/ foreword .html.
ISO 52003-1 was prepared by ISO Technical Committee TC 163, Thermal performance and energy use in
the built environment, in collaboration with Technical Committee TC 205, Building environment design,
and with the European Committee for Standardization (CEN) Technical Committee CEN/TC 89, Thermal
performance of buildings and building components, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This first edition of ISO 52003-1 cancels and replaces ISO 16343:2013, which has been technically
revised.
The necessary editorial revisions were made to comply with the requirements for each EPB standard.
The content of ISO 16343 has been reworked significantly, but it has been attempted not to lose
any substantial original information, even though the original text has sometimes been strongly
restructured and rephrased, and new content has been added throughout. The original text has been
split into 2 parts: a normative standard and an informative technical report.
A list of all parts in the ISO 52003 series can be found on the ISO website.

Introduction
This document is part of a series aimed at the international harmonization of the methodology for
assessing the energy performance of buildings. Throughout, this series is referred to as a “set of EPB
standards”.
All EPB standards follow specific rules to ensure overall consistency, unambiguity and transparency.
All EPB standards provide a certain flexibility with regard to the methods, the required input data and
references to other EPB standards, by the introduction of a normative template in Annex A and Annex B
with informative default choices.
For the correct use of this document, a normative template is given in Annex A to specify these choices.
Informative default choices are provided in Annex B.
The main target groups for this document are architects, engineers and regulators.
Use by or for regulators: In case the document is used in the context of national or regional legal
requirements, mandatory choices may be given at national or regional level for such specific
applications. These choices (either the informative default choices from Annex B or choices adapted to
national/regional needs, but in any case following the template of Annex A) can be made available as
national annex or as separate (e.g. legal) document (national data sheet).
NOTE 1 So in this case:
— the regulators will specify the choices;
— the individual user will apply the document to assess the energy performance of a building, and thereby use
the choices made by the regulators.
Topics addressed in this document can be subject to public regulation. Public regulation on the same
topics can override the default values in Annex B. Public regulation on the same topics can even, for
certain applications, override the use of this document. Legal requirements and choices are in general
not published in standards but in legal documents. In order to avoid double publications and difficult
updating of double documents, a national annex may refer to the legal texts where national choices
have been made by public authorities. Different national annexes or national data sheets are possible,
for different applications.
It is expected, if the default values, choices and references to other EPB standards in Annex B are not
followed due to national regulations, policy or traditions, that:
— national or regional authorities prepare data sheets containing the choices and national or regional
values, according to the model in Annex A. In this case a national annex (e.g. NA) is recommended,
containing a reference to these data sheets;
— or, by default, the national standards body will consider the possibility to add or include a national
annex in agreement with the template of Annex A, in accordance to the legal documents that give
national or regional values and choices.
Further target groups are parties wanting to motivate their assumptions by classifying the building
energy performance for a dedicated building stock.
More information is provided in the Technical Report accompanying this document (ISO/TR 52003-2).
The overall and partial EPB indicators, i.e. the quantitative output of EPB assessments, can be used for
different purposes:
1) Requirements: to set public or private requirements regarding the energy performance of buildings.
2) Decisions: to facilitate decisions or actions in the private or public domain.

ISO 52003-1:2017(E)

3) Information and communication: for building designers, owners, operators, users, policy makers
and citizens (as sellers or renters, as prospective buyers or tenants).
This document and ISO/TR 52003-2 deal with several of these uses, which can generically be described
as the post-processing of the outputs of the EPB assessment methods (see 5.1).
The main focus of the actual (normative) standard, i.e. this document, is on basic concepts and relations
and on the actions that need to be taken. The accompanying (informative) technical report, i.e.
ISO/TR 52003-2, provides extensive further information to support actors in a judicious implementation.
For optimal understanding, both documents are therefore best read side-by-side, clause-by-clause.
This document and ISO/TR 52003-2 are complemented by
— ISO 52018-1 and ISO/TR 52018-2 that deal with partial EPB requirements related to thermal energy
balance and fabric features, and
— CEN EPB standards that deal with the same topics for specific technical building systems, servicing
specific types of energy use (such as heating, cooling, ventilation, domestic hot water and lighting).
Much of the content of these texts may be commonplace to those experienced in the domain. However,
it has been decided to document basic considerations with a view to fully informing any interested
party, including novices in the field. The texts thus partly serve as “institutional memory”. The aim is to
contribute to well-informed choices and also to any future revision of a regulation (choice of the mix of
EPB features and indicators, variable or constant value requirements and/or rating references, actual
requirement strictness).
Table 1 shows the relative position of this document within the set of EPB standards in the context of
the modular structure as set out in ISO 52000-1.
NOTE 2 In ISO/TR 52000-2, the same table can be found with, for each module, the numbers of the relevant
EPB standards and accompanying technical reports that are published or in preparation.
The modules represent EPB standards, although one EPB standard may cover more than one module
and one module may be covered by more than one EPB standard, for instance, a simplified and a detailed
method respectively. See also Clause 2 and Tables A.1 and B.1.

Evropski predgovor

Ta dokument (EN ISO 52003-1:2017) je pripravil tehnični odbor ISO/TC 163 "Toplotne lastnosti in raba
energije v grajenem okolju" v sodelovanju s tehničnim odborom CEN/TC 89 "Toplotne lastnosti stavb in
gradbenih komponent", katerega sekretariat vodi SIS.

Ta evropski standard mora dobiti status nacionalnega standarda bodisi z objavo istovetnega besedila
ali z razglasitvijo najpozneje januarja 2018, nasprotujoče nacionalne standarde pa je treba razveljaviti
najpozneje januarja 2018.

Opozoriti je treba na možnost, da bi lahko bil kateri od elementov tega dokumenta predmet patentnih
pravic. CEN ni odgovoren za identificiranje nobene od teh patentnih pravic.
Ta dokument je bil pripravljen v okviru mandata, ki sta ga Evropska komisija in Evropsko združenje za
prosto trgovino (EFTA) dala CEN.
Ta dokument je del nabora standardov o energijskih lastnostih stavb (nabor standardov EPB), ki jih je
CEN pripravil na podlagi mandata Evropske komisije in Evropskega združenja za prosto trgovino
(mandat M/480, glej referenco [EF1] spodaj), in podpira bistvene zahteve Direktive EU 2010/31/ES o
energetski učinkovitosti stavb (EPBD, [EF2]).

Če se ta standard uporablja v okviru nacionalnih ali regionalnih zakonskih zahtev, se lahko za takšne
vrste uporabe uporabijo obvezne izbire, zlasti za uporabo v okviru direktiv EU, prenesenih v nacionalne
zakonodajne zahteve.

Druge ciljne skupine so uporabniki prostovoljne skupne sheme certificiranja Evropske unije za
energetsko učinkovitost nestanovanjskih stavb (EPBD, člen 11.9) in vse druge regionalne (npr.

SIST EN ISO 52003-1 : 2017
Predgovor k mednarodnemu standardu

Mednarodna organizacija za standardizacijo (ISO) je svetovna zveza nacionalnih organov za standarde
(članov ISO). Mednarodne standarde običajno pripravljajo tehnični odbori ISO. Vsak član, ki ga zanima
področje, za katero je bil ustanovljen tehnični odbor, ima pravico biti zastopan v tem odboru. Pri delu
sodelujejo tudi mednarodne vladne in nevladne organizacije, povezane z ISO. V vseh zadevah, ki se
nanašajo na standardizacijo s področja elektrotehnike, ISO tesno sodeluje z Mednarodno
elektrotehniško komisijo (IEC).

Postopki, uporabljeni pri razvoju tega dokumenta, in postopki, predvideni za njegovo nadaljnje
vzdrževanje, so opisani v Direktivah ISO/IEC, 1. del. Posebno pozornost je treba nameniti različnim
kriterijem odobritve, potrebnim za različne vrste dokumentov ISO. Ta dokument je bil pripravljen v skladu
z uredniškimi pravili Direktiv ISO/IEC, 2. del (glej www.iso.org/directives).

Opozoriti je treba na možnost, da za nekatere elemente tega dokumenta lahko veljajo patentne pravice.
ISO ne prevzema odgovornosti za identifikacijo katerihkoli ali vseh takih patentnih pravic. Podrobnosti
o katerihkoli patentnih pravicah, identificiranih med pripravo tega dokumenta, bodo navedene v uvodu
in/ali na seznamu patentnih izjav, ki jih je prejela organizacija ISO (glej www.iso.org/patents).

Vsakršno trgovsko ime, uporabljeno v tem dokumentu, je informacija za uporabnike in ne pomeni
podpore blagovni znamki.

Za razlago prostovoljne narave standardov, pomena posebnih izrazov ISO, povezanih z ugotavljanjem
skladnosti, ter informacij o tem, kako ISO spoštuje načela Mednarodne trgovinske organizacije (WTO)
v Tehničnih ovirah pri trgovanju, glej naslednji naslov URL: Foreword - Supplementary information.

Standard 52003-1 je pripravil tehnični odbor Mednarodne organizacije za standardizacijo ISO/TC 163
Toplotne lastnosti in raba energije v grajenem okolju v sodelovanju s tehničnim odborom ISO/TC 205
Projektiranje grajenega okolja in tehničnim odborom Evropskega odbora za standardizacijo CEN/TC 89
Toplotne lastnosti stavb in gradbenih komponent v skladu s Sporazumom o tehničnem sodelovanju med
ISO in CEN (Dunajski sporazum).

Ta prva izdaja standarda ISO 52003-1 razveljavlja in nadomešča standard ISO 16343:2013, ki je bil
strokovno revidiran.

Za zagotovitev skladnosti z zahtevami so bile narejene potrebne uredniške revizije za vsak standard
EPB. Vsebina standarda ISO 16343 je bila precej spremenjena ob prizadevanju, da ne bi izgubili
nobenih bistvenih izvirnih informacij, čeprav je bilo izvirno besedilo včasih precej prestrukturirano in
preoblikovano, v celotnem dokumentu pa so bile dodane nove vsebine. Izvirno besedilo je razdeljeno
na dva dela: normativni standard in informativno tehnično poročilo.

Seznam vseh delov skupine standardov ISO 52003 je na voljo na spletni strani ISO.

SIST EN ISO 52003-1 : 2017
Uvod
Ta dokument je eden iz skupine standardov, katerih namen je uskladiti metodologijo za ocenjevanje
energijskih lastnosti stavb. V nadaljevanju se ta skupina imenuje "nabor standardov EPB".
Vsi standardi EPB sledijo posebnim pravilom, s katerimi se zagotavljajo splošna doslednost,
nedvoumnost in preglednost.
Vsi standardi EPB zagotavljajo določeno prilagodljivost glede na metode, zahtevane vhodne podatke in
sklicevanja na druge standarde EPB z normativno predlogo v dodatku A in informativnimi privzetimi
izbirami v dodatku B.
Za pravilno uporabo tega dokumenta je v dodatku A podana normativna predloga, ki določa te izbire.
Informativne privzete izbire so na voljo v dodatku B.
Glavne ciljne skupine za uporabo tega dokumenta so arhitekti, inženirji in zakonodajalci.
Kadar dokument uporabljajo zakonodajalci ali kadar se uporablja zanje: če se dokument uporablja v
okviru nacionalnih ali regionalnih zakonodajnih zahtev, je za takšne posebne uporabe mogoče obvezne
izbire sprejeti na nacionalni ali regionalni ravni. Te izbire (bodisi informativne privzete izbire iz dodatka
B ali izbire, prilagojene nacionalnim/regionalnim potrebam, ki pa so vse v skladu s predlogo iz dodatka
A) so lahko na voljo kot nacionalni dodatek ali kot ločen (npr. pravni) dokument (nacionalni podatkovni
list).
OPOMBA 1: V tem primeru:
– zakonodajalci določijo izbire;
– posamezen uporabnik uporabi dokument za oceno energijskih lastnosti stavbe in pri tem uporabi izbire, ki
so jih predpisali zakonodajalci.
Za teme, obravnavane v tem dokumentu, morda veljajo tudi javni predpisi. Javni predpis o istih temah
lahko preglasi privzete vrednosti iz dodatka B. Pri nekaterih primerih uporabe lahko javni predpis o istih
temah celo preglasi uporabo tega dokumenta. Pravne zahteve in izbire na splošno niso objavljene v
standardih, ampak v pravnih dokumentih. Da bi se izognili dvojnim objavam in zamudnemu
posodabljanju dvojnih dokumentov, se lahko nacionalni dodatek sklicuje na pravna besedila, s
katerimi so javni organi sprejeli nacionalne izbire. Za različne vrste uporabe so možni različni
nacionalni dodatki ali nacionalni podatkovni listi.
Kadar se privzete vrednosti, izbire in sklicevanja na druge standarde EPB v dodatku B ne upoštevajo
zaradi nacionalnih predpisov, politike ali tradicije, se pričakuje, da:
– nacionalni ali regionalni organi pripravijo podatkovne liste, ki vsebujejo izbire in nacionalne ali
regionalne vrednosti po vzorcu v dodatku A. V tem primeru se priporoča, da se v nacionalni dodatek
(tj. NA) doda sklic na te podatkovne liste;
– ali da, praviloma, nacionalni organ za standarde preuči možnost za dodajanje ali vključitev
nacionalnega dodatka v skladu s predlogo iz dodatka A ter v skladu s pravnimi dokumenti, ki
vsebujejo nacionalne ali regionalne vrednosti ter izbire.
Druge ciljne skupine so stranke, ki želijo utemeljiti svoje predpostavke, ko namenski stavbni fond
razvrščajo po energijskih lastnostih.
Več informacij je na voljo v tehničnem poročilu, ki je priloženo temu dokumentu (ISO/TR 52003-2).
Splošne in delne kazalnike EPB, tj. količinske izhodne podatke ocene EPB, je mogoče uporabiti za
različne namene:
1) zahteve: določiti javne ali zasebne zahteve za energijske lastnosti stavb,
2) odločitve: olajšati odločitve ali dejanja v zasebni ali javni domeni,
6

---------------------- Page: 8 ----------------------
SIST EN ISO 52003-1 : 2017
3) informacije in komunikacija: za gradbene projektante, lastnike, upravljavce, uporabnike,
oblikovalce politike in državljane (v vlogi prodajalcev ali najemnikov, bodočih kupcev ali bodočih
najemnikov).

Ta dokument in ISO/TR 52003-2 obravnavata več teh načinov uporabe, ki jih je mogoče splošno opisati
kot naknadna obdelava izhodnih podatkov metod ocenjevanja EPB (glej 5.1).

Glavni poudarek aktualnega (normativnega) standarda, tj. tega dokumenta, je na osnovnih pojmih in
odnosih ter na ukrepih, ki jih je treba sprejeti. Priloženo (informativno) tehnično poročilo, tj. ISO/TR
52003-2, vsebuje obsežne dodatne informacije v pomoč uporabnikom pri preudarnem izvajanju tega
standarda. Za optimalno razumevanje je torej najbolje brati oba dokumenta vzporedno, točko za točko.

Ta dokument in ISO/TR 52003-2 se dopolnjujeta z:

‒ ISO 52018-1 in ISO/TR 52018-2, ki obravnavata delne zahteve EPB, povezane z bilanco toplotne
energije in lastnostmi stavbnega tkiva, ter

‒ standardi CEN EPB, ki obravnavajo iste teme za specifične tehnične gradbene sisteme,
servisiranje posebnih vrst rabe energije (kot so ogrevanje, hlajenje, prezračevanje, sanitarna voda
in razsvetljava).

Večina vsebine teh besedil je uporabnikom, ki imajo izkušnje na tem področju, morda dobro znana.
Vendar je bilo odločeno, da se osnovne zadeve dokumentirajo, da bodo primerno obveščene vse
zainteresirane strani, vključno z novinci na tem področju. Besedila tako deloma služijo kot "institucionalni
pomnilnik". Cilj je, da so možnosti podprte z dovolj informacijami in da bo v prihodnosti mogoča revizija
ureditve (izbira kombinacije značilnosti EPB in kazalnikov, spremenljivih ali stalnih vrednosti zahtev in/ali
referenčnih ocen, dejanske strogosti zahteve).

Preglednica 1 prikazuje relativni položaj tega dokumenta znotraj nabora standardov EPB v kontekstu
modularne strukture, kot je opredeljeno v standardu ISO 52000-1.

OPOMBA 2: V standardu ISO/TR 52000-2 je za vsak modul mogoče najti enako preglednico s številkami ustreznih standardov
EPB in spremljajočimi tehničnimi poročili, ki so objavljena ali v pripravi.

Moduli predstavljajo standarde EPB, čeprav lahko en standard EPB zajema več kot en modul, en modul
pa je lahko zajet z več kot enim standardom EPB, na primer poenostavljena in podrobna metoda. Glej
tudi točko 2 ter preglednici A.1 in B.1.

Energijske lastnosti stavb – Kazalniki, zahteve, opredelitev rabe energije in certifikati –
1. del: Splošni vidiki in uporaba za skupno energijsko lastnost

1 Področje uporabe

Nabor standardov za oceno EPB v svojih izhodnih podatkih ustvarja veliko število skupnih in delnih
kazalnikov EPB. Ta dokument omogoča tako zasebnikom kot zakonodajalcem (in vsem zainteresiranim
stranem, ki sodelujejo v regulativnem postopku), da uporabijo te podatke za različne namene (nadaljnja
obdelava).

Ta dokument opisuje razmerje med kazalniki EPB, zahtevami EPB in stopnjami EPB ter obravnava
pomembnost projektno specifičnih, prilagojenih vrednosti, ki se uporabljajo kot zahteve ali reference za
nekatere kazalnike EPB. Dokument vključuje tudi nekaj možnih oznak EPB in navaja različne korake, ki
jih je treba opraviti pri vzpostavljanju sheme certificiranja EPB.

Dokument vsebuje standardizirane preglednice za strukturiran in pregleden opis možnosti, ki jih je treba
izbrati glede na splošne zahteve EPB. Preglednice niso omejevalne, tako da je mogoče zakonodajo
povsem prilagoditi. Za delne zahteve EPB (povezane z lastnostmi stavbnega tkiva ali tehničnimi
gradbenimi sistemi) v dokumentu ni takšnih preglednic, ker so obravnavane v drugih dokumentih.

OPOMBA: Preglednica 1 v uvodu prikazuje relativni položaj tega dokumenta znotraj nabora standardov EPB v kontekstu
modularne strukture, kot je opredeljena v standardu ISO 52000-1.

draft ISO/DIS 52003-1
Introduction
This Standard is part of a series of standards aiming at the international harmonisation of the methodology for
the assessment of the energy performance of buildings, called "set of EPB standards".
As part of the "set of EPB standards" it complies with the requirements for the set of basic EPB documents
(ISO 52000-1 (see Normative references), CEN/TS 16628 and CEN/TS 16629 (see bibliography [3] and [4])
developed under a mandate given to CEN by the European Commission and the European Free Trade
Association (Mandate M/480, [5]), and supports essential requirements of EU Directive 2010/31/EC on the
energy performance of buildings (EPBD) [6].
This International Standard presents some general concepts on EPB features and indicators. It also presents
a coherent set of complementary and alternative ways to express the overall energy performance and energy
performance requirements at overarching level (building including the technical building systems).
References are made to other International Standards or to national documents for input data and
assessment procedures not provided by this International Standard.
The new texts are structured in accordance with the rules for EPB standards.
The content of ISO 16343 has been reworked significantly, but it has been attempted not to lose any
substantial original content, although the original text has sometimes been strongly restructured and
rephrased, and new content has been added. In the new text, for the purpose of clarity, requirements and
ratings are treated as two autonomous uses of EPB indicators, each in its own right, although in practical
application both may be closely integrated into a single, unified regulation.
Informative parts of ISO 16343 (notably annexes) have been transferred to the technical report, ISO/TR
52003-2 [7].
Some of the content of this text will be commonplace to those experienced in the domain. However, it has
been decided to document also basic considerations with a view of fully informing interested parties, including
novices in the field (eg new staff in ministries, maybe politicians and policy makers, who get involved in setting
requirements, etc.) The aim is to contribute to well-informed choices, also at future revisions of the
requirements (mix of EPB features&indicators, way to express each of them, actual strictness).
This International Standard is complemented by EPB standard ISO 52018-1, dealing with partial EPB
requirements related to thermal energy balance and fabric features. It is also complemented by CEN EPB
standards dealing with the same topics for specific technical building systems, servicing specific types of
energy use (such as heating, cooling, ventilation, domestic hot water and lighting).
Because of its special subject, the rationale behind the options provided in this EPB standard is provided in
the standard itself (where appropriate as normative text, otherwise as notes), with more detailed
considerations, examples and justification provided in the accompanying technical report, ISO/TR 52003-2 [7].
For best understanding, the reader is therefore strongly advised to read parts 1 and 2 in parallel, clause by
clause.
This standard and its accompanying technical report contain much basic information, which has been included
with a view of making the texts more easily accessible to readers who are new to the subject. The Foreword,
the Introduction and Notes in an international standard are purely informative and do not contain normative
procedures or references.
The main changes compared to ISO/CD 52003-1 are the following:

Draft ISO/DIS 52003-1
 Several paragraphs have been moved to the accompanying technical report (ISO/TR 52003-2, in
preparation).
 The normative references to other EPB standards have been moved to Annex A/B (as in draft ISO
52000-1).
 A separate clause on Rating has been made (in previous CD version: §§ 8.1, 8.3 and 9.4).
 An autonomous clause on fixed and variable requirement & reference values has been made.
 From the standard(s) to be succeded, a worked out certificate model has been re-introduced, as one
of the options to choose.
 Editorial improvements.
Anticipated changes on DIS version:
 Continued (parallel) tuning with draft ISO 52000-1 (overarching standard).
 Deal with remaining comments received on CD version (mainly editorial, or comments that concern
the whole set pf EPB standards or that concern this standard in combination with draft ISO 52000-1
(overarching standard).
1 Scope
The overall and partial EPB indcators, i.e. the quantitative output of EPB assessments, can be used for
different purposes:
1) Regulations: to enable the establishment of regulations regarding the energy performance of
buildings;
2) Decisions: to facilitate decisions or actions in the private or public domain, and
3) Information and communication: for building designers, owners, operators, users, policy
makers and citizens (as sellers or renters, as prospective buyers or tenants).
This standard provides a framework for possible ways to express the energy performance, especially for the
purpose of setting EPB requirements at the overarching level of the building including the technical building
systems and for energy (performance) certification and labelling.
This standard is complemented by standards dealing with the same topics at the level of the building itself (i.e.
mostly without technical systems), of the technical building systems and of building elements (e.g. building
fabric and technical building system elements).
Possible ways to express the energy performance for the purpose of setting EPB requirements cover the
objectives 1) and 2) above.
This standard provides also a common basis and common considerations for the subsequent EPB standards
dealing with the same subject for the building itself (the fabric) and the building elements and for specific
technical building systems, servicing specific types of energy use (such as heating, cooling, ventilation,
domestic hot water and lighting).
(NOTE For this purpose this standard is supported by the accompanying technical report, ISO/TR 52003-2 [7]
This standard provides a structured and transparent framework for different (non-restrictive) options, enabling
direct reference in national regulations, while providing flexibility for regulatory choices.

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

1
and procedures
Default references to other EPB standards, identified by the EPB module code number, are given in
Table B.1. If alternative references are specified, then the template given in Table A.1 shall be used.
NOTE 1 Example of EPB module code number: M5-5, or M5-5.1 (if module M5-5 is subdivided), or M5-5/1 (if reference
to a specific clause of the standard covering M5-5).
NOTE 2 The same module code numbering will be used in other EPB standards. This will facilitate -in a individual
country- the making of a consistent set of national annexes for each EPB standard and contribute to the overall
consistency and transparency.
3 Terms and definitions
2
For the purposes of this Standard, the terms and definitions given in ISO 7345:1995, ISO 52000-1 and the
following specific definitions apply. For the readers' convenience the terms of ISO 52000-1 that are used in
the underlying standard are repeated here.
NOTE 1 The latter are repeated only if indispensable for the overall understanding of this standard.
NOTE 2 The content of Clause 3 of this draft standard is already as much as possible tuned with draft ISO 52000-1,
but comments and discussions on draft ISO 52000-1 and this draft standard may lead to (proposals for) changes. Such
changes need to be checked for overall consistency.
NOTE 3 After enquiry the list of terms copied from ISO 520000-1 may be extended, because more of thesee may be
relevant for the underlying standard.
3.1 Buildings
3.1.1
assessed building(s) (unit) *
building(s) or part of the building resp. building unit that is the object of the energy performance assessment
NOTE 1 Comprises all spaces and technical systems which may contribute to or influence the energy performance
assessment.
NOTE 2 The assessed building may include one or more building units, if these are not individually object of the energy
performance assessment.
NOTE 3 A distinction may be made between e.g. a designed building, new building after construction, existing building
in the use phase and existing building after major renovation.

3.1.2
building *
construction as a whole, including the fabric and all technical building systems, where energy is used to
condition the indoor environment, to provide domestic hot water and illumination and other services related to
the use of the building
NOTE 1 The term refers to the physical building as a whole or to all parts thereof that at least include the spaces and
technical building systems that are relevant for the energy performance assessment.
NOTE 2 Building parts can be physically detached, but are on the same building site. For example: a canteen or a
guard house or one or more class rooms of a school in a detached building part; or an essential space in a dwelling (e.g.
bedroom).
3.1. 3
building element *
element of the technical building systems or element of the building fabric
3.1.4
building services *
services provided by technical building systems and by appliances to provide acceptable indoor environment
conditions, domestic hot water, illumination levels and other services related to the use of the building
3.1.5
building unit *
a section, floor or apartment within a building which is designed or altered to be used separately
NOTE 1 The building unit can be the assessed object.
NOTE 2 The definition is copied from the EPBD.
EXAMPLE A shop in a shopping mall, an apartment in an apartment building, a rentable office space in an office
building
3.1.6
building (unit) category *
classification of buildings and/or building units related to their main use or their special status, for the purpose
of enabling differentiation of the energy performance assessment procedures and/or energy performance
requirements
NOTE 1 In Europe, several articles of the Directive 2010/31/EU of the European Parliament and of the council of 19
May 2010 on the energy performance of buildings (EPBD) make a distinction between building categories.
NOTE 2 The building category, for instance, may determine if energy performance assessment is mandatory (e.g. not
for religious or historic buildings) and which are the minimum energy performance requirements (e.g. for new buildings); in
some countries measured energy performance
