Energy performance of buildings - Indicators for partial EPB requirements related to thermal energy balance and fabric features - Part 1: Overview of options (ISO 52018-1:2017)

This new international standard will provide ways to express the energy performance and energy performance requirements at the level of the building as such, the building envelope and the building elements.

Energieeffizienz von Gebäuden - Indikatoren für EPB-Teilanforderungen im Hinblick auf die Wärmeenergiebilanz und Funktionen der Bausubstanz - Teil 1: Überblick über die Möglichkeiten (ISO 52018-1:2017)

Das Paket der EPB-Bewertungsnormen erzeugt eine große Anzahl an Indikatoren für die Gesamt- und die Teilenergieeffizienz als Ausgabewerte, die zu verschiedenen Zwecken genutzt werden können. Dieses Dokument behandelt die Nutzung der Indikatoren für die Teilenergieeffizienz in Bezug auf die Bausubstanz und die Wärmebilanz des Gebäudes. Aspekte der Wärmebilanz betreffen sowohl den Heiz- als auch den Kühlbedarf und die Gleichgewichtstemperaturbedingungen, insbesondere in Bezug auf Überhitzung oder zu niedrige Innenraumtemperaturen. Dieses Dokument kann sowohl private Parteien als auch öffentliche Regulierungsbehörden (sowie alle am Regulierungsprozess beteiligten Interessenvertreter) bei der Nachbearbeitung dieser Ausgabewerte unterstützen.
Dieses Dokument bietet standardisierte Tabellen für die strukturierte und transparente Erfassung der Auswahlmöglichkeiten, die hinsichtlich der EPB-Teilanforderungen, die Gegenstand dieses Dokuments sind, zu treffen sind. Die Tabellen sind nicht einschränkend und ermöglichen volle regulatorische Flexibilität.
ANMERKUNG Tabelle 1 in der Einleitung zeigt die relative Position dieses Dokuments innerhalb des EPB-Normenpakets im Kontext der in ISO 52000-1 dargelegten modularen Struktur.

Performance énergétique des bâtiments - Indicateurs et exigences de PEB partielle liées aux éléments du bilan énergétique thermique et aux éléments d'enveloppe - Partie 1: Aperçu des options (ISO 52018-1:2017)

L'ensemble des normes d'évaluation de la PEB produit comme résultats un grand nombre d'indicateurs PEB globaux et partiels, qui peuvent être utilisés à différentes fins. L'ISO 52018-1:2017 traite de l'utilisation en tant qu'exigence des indicateurs PEB partiels liés à la structure et à l'équilibre thermique du bâtiment. Les aspects d'équilibre thermique concernent les besoins de chauffage et de refroidissement, ainsi que les températures flottantes libres, surtout en matière de surchauffe ou de températures intérieures trop froides. L'ISO 52018-1:2017 peut aider les parties privées et les autorités de réglementation publiques (et tous les acteurs impliqués dans le processus réglementaire) avec le « post-traitement » de ces résultats.
L'ISO 52018-1:2017 fournit des tableaux normalisés pour la consignation, d'une manière structurée et transparente, des choix qui doivent être faits par rapport aux exigences de PEB partielle couvertes par l'ISO 52018-1:2017. Les tableaux ne sont pas restrictifs et offrent donc une flexibilité réglementaire totale.
NOTE       Le Tableau 1 de l'Introduction indique la position relative de l'ISO 52018-1:2017 dans la série de normes PEB dans le contexte de la structure modulaire définie dans l'ISO 52000‑1.

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).

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 (ISO/TR 52018-2) accompanying this document.
The subset of EPB standards prepared under the responsibility of ISO/TC 163/SC 2 cover inter alia:
— calculation procedures on the overall energy use and energy performance of buildings;
— calculation procedures on the indoor temperature in buildings (e.g. in case of no space heating or
cooling);
— indicators for partial EPB requirements related to thermal energy balance and fabric features;

---------------------- Page: 11 ----------------------
SIST EN ISO 52018-1:2017
ISO 52018-1:2017(E)

— calculation methods covering the performance and thermal, hygrothermal, solar and visual
characteristics of specific parts of the building and specific building elements and components, such
as opaque envelope elements, ground floor, windows and facades.
ISO/TC 163/SC 2 cooperates with other technical committees for the details on, for example, appliances,
technical building systems and indoor environment.
The overall and partial EPB indicators, i.e. the quantitative output of EPB assessments, can be used for
different purposes.
a) Requirements: To set public or private requirements regarding the energy performance of
buildings.
b) Decisions: To facilitate decisions or actions in the private or public domain.
c) Information and communication: For building designers, owners, operators, users, policymakers
and citizens (as sellers or renters, as prospective buyers or tenants).
ISO 52003-1 and ISO 52003-2 discuss in a general manner the post-processing of the outputs of the EPB
standards. They describe the concepts of EPB features and EPB indicators and deal with the principles
of requirements, ratings and certificates. They also briefly deal in a more practical manner with the
overall EPB requirements.
This document deals on a practical level with the requirements related to the fabric and related to
the thermal balance of the building. Thermal balance aspects concern both the heating and cooling
needs and the free floating temperatures, especially with respect to overheating or too cold indoor
temperatures.
Most of the EPB features falling within this scope are succinctly enumerated and for each of them, many
possible indicators are listed. Annex A provides standardized tables to report the choices that are made
by regulators. Annex B gives motivated default choices.
As ISO 52003-1, this document does not provide any EPB assessment method (calculation, measurement
of inspection). Instead, they refer to other EPB and non-EPB standards for the determination of EPB
indicators.
ISO/TR 52018-2 is the technical report corresponding to this document. It provides extensive
background information to help with making well-considered choices. For best understanding, the
reader is advised to read this document and ISO/TR 52018-2 in parallel, clause by clause.
EPB indicators that can possibly be used for setting requirements to technical building systems are in
principle covered in the corresponding EPB documents (which are until now mostly CEN standards).
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.
NOTE 3 The modules represent EPB standards, although one EPB standard could cover more
than one module and one module could 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.

Energy performance of buildings — Indicators for partial
EPB requirements related to thermal energy balance and
fabric features —
Part 1:
Overview of options
1 Scope
The set of EPB assessment standards produces a great number of overall and partial EPB indicators as
outputs, which can be used for different purposes. This document deals with the use as requirement of
partial EPB indicators related to the fabric and related to the thermal balance of the building. Thermal
balance aspects concern both the heating and cooling needs and the free floating temperatures,
especially with respect to overheating or too cold indoor temperatures. This document can support
both private parties and public regulators (and all stakeholders involved in the regulatory process)
with the “post-processing” of these outputs.
This document provides standardized tables for reporting, in a structured and transparent manner,
the choices that are to be made with respect to the partial EPB requirements covered by this document.
The tables are non-restrictive, thus allowing for full regulatory flexibility.
NOTE Table 1 in the Introduction 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.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements 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.
NOTE 1 In addition, Annex C contains specific parallel routes in referencing standards, in order to take into
account existing national and/or regional regulations and/or legal environments while maintaining global
relevance.
NOTE 2 Default references to EPB standards other than ISO 52000-1 are identified by the EPB module code
number and given in Annex A (normative template) and Annex B (informative default choice).
EXAMPLE 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).

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

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 (ISO/TR 52018-2) accompanying this document.
The subset of EPB standards prepared under the responsibility of ISO/TC 163/SC 2 cover inter alia:
— calculation procedures on the overall energy use and energy performance of buildings;
— calculation procedures on the indoor temperature in buildings (e.g. in case of no space heating or
cooling);
— indicators for partial EPB requirements related to thermal energy balance and fabric features;

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

SIST EN ISO 52018-1:2017
ISO 52018-1:2017(E)

— calculation methods covering the performance and thermal, hygrothermal, solar and visual
characteristics of specific parts of the building and specific building elements and components, such
as opaque envelope elements, ground floor, windows and facades.
ISO/TC 163/SC 2 cooperates with other technical committees for the details on, for example, appliances,
technical building systems and indoor environment.
The overall and partial EPB indicators, i.e. the quantitative output of EPB assessments, can be used for
different purposes.
a) Requirements: To set public or private requirements regarding the energy performance of
buildings.
b) Decisions: To facilitate decisions or actions in the private or public domain.
c) Information and communication: For building designers, owners, operators, users, policymakers
and citizens (as sellers or renters, as prospective buyers or tenants).
ISO 52003-1 and ISO 52003-2 discuss in a general manner the post-processing of the outputs of the EPB
standards. They describe the concepts of EPB features and EPB indicators and deal with the principles
of requirements, ratings and certificates. They also briefly deal in a more practical manner with the
overall EPB requirements.
This document deals on a practical level with the requirements related to the fabric and related to
the thermal balance of the building. Thermal balance aspects concern both the heating and cooling
needs and the free floating temperatures, especially with respect to overheating or too cold indoor
temperatures.
Most of the EPB features falling within this scope are succinctly enumerated and for each of them, many
possible indicators are listed. Annex A provides standardized tables to report the choices that are made
by regulators. Annex B gives motivated default choices.
As ISO 52003-1, this document does not provide any EPB assessment method (calculation, measurement
of inspection). Instead, they refer to other EPB and non-EPB standards for the determination of EPB
indicators.
ISO/TR 52018-2 is the technical report corresponding to this document. It provides extensive
background information to help with making well-considered choices. For best understanding, the
reader is advised to read this document and ISO/TR 52018-2 in parallel, clause by clause.
EPB indicators that can possibly be used for setting requirements to technical building systems are in
principle covered in the corresponding EPB documents (which are until now mostly CEN standards).
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.
NOTE 3 The modules represent EPB standards, although one EPB standard could cover more
than one module and one module could 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.

fabric features —
Part 1:
Overview of options
1 Scope
The set of EPB assessment standards produces a great number of overall and partial EPB indicators as
outputs, which can be used for different purposes. This document deals with the use as requirement of
partial EPB indicators related to the fabric and related to the thermal balance of the building. Thermal
balance aspects concern both the heating and cooling needs and the free floating temperatures,
especially with respect to overheating or too cold indoor temperatures. This document can support
both private parties and public regulators (and all stakeholders involved in the regulatory process)
with the “post-processing” of these outputs.
This document provides standardized tables for reporting, in a structured and transparent manner,
the choices that are to be made with respect to the partial EPB requirements covered by this document.
The tables are non-restrictive, thus allowing for full regulatory flexibility.
NOTE Table 1 in the Introduction 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.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements 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.
NOTE 1 In addition, Annex C contains specific parallel routes in referencing standards, in order to take into
account existing national and/or regional regulations and/or legal environments while maintaining global
relevance.
NOTE 2 Default references to EPB standards other than ISO 52000-1 are identified by the EPB module code
number and given in Annex A (normative template) and Annex B (informative default choice).
EXAMPLE 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).

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).

SIST EN ISO 52018-1 : 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 52018-2).

Podniz standardov EPB, ki so pripravljeni pod odgovornostjo ISO/TC 163/SC 2 zajema inter alia:

– postopke za računanje celotne rabe energije in energijskih lastnosti stavb;

– postopke za računanje notranje temperature v stavbah (npr. v primeru brez ogrevanja ali hlajenja);

5

---------------------- Page: 9 ----------------------
SIST EN ISO 52018-1 : 2017

– kazalnike delnih zahtev EPB, povezanih z bilanco toplotne energije in značilnostmi stavbnega tkiva;

– računske metode, ki zajemajo lastnosti ter toplotne, higrotermalne, solarne in vizualne značilnosti
posebnih delov stavbe in posebnih gradbenih elementov in komponent, kot so neprozorni elementi
ovoja, tla, okna in fasade.

ISO/TC 163/SC 2 sodeluje z drugimi tehničnimi odbori glede podrobnosti o npr. napravah, tehničnih
sistemih v stavbi in notranjem okolju.

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,

3) informacije in komunikacija: za gradbene projektante, lastnike, upravljavce, uporabnike,
oblikovalce politike in državljane (v vlogi prodajalcev ali najemnikov, bodočih kupcev ali bodočih
najemnikov).

Standarda ISO 52003-1 in ISO 52003-2 na splošno obravnavata naknadno obdelavo izhodnih podatkov
standardov EPB. Opisujeta koncepte značilnosti EPB in kazalnikov EPB ter obravnavata načela zahtev,
opredelitev rabe in certifikatov. Prav tako na kratko in bolj praktično obravnavata splošne zahteve EPB.

Ta dokument na praktičen način obravnava zahteve v zvezi s stavbnim tkivom in bilanco toplotne
energije stavbe. Vidiki bilance toplotne energije se navezujejo tako na potrebe po ogrevanju in hlajenju
kot na temperature v nekontroliranih pogojih, zlasti v povezavi s pregrevanjem ali prehladnimi notranjimi
temperaturami.

Večina značilnosti EPB, ki spadajo na to področje uporabe, je jedrnato našteta, za vsako posebej pa so
navedeni številni možni kazalniki. Dodatek A vsebuje standardizirane preglednice za poročanje o
izbirah, ki jih določijo zakonodajalci. Dodatek B podaja utemeljene privzete izbire.

Kot standard ISO 52003-1 tudi ta dokument ne podaja nobenih metod ocenjevanja EPB (izračuni,
merjenje pri nadzoru). Namesto tega se za določanje kazalnikov EPB sklicujeta na druge standarde
EPB in standarde, ki ne zadevajo EPB.

ISO/TR 52018-2 je tehnično poročilo, ki ustreza temu dokumentu. Podaja obsežno informativno ozadje
za pomoč pri sprejemanju dobro premišljenih izbir. Za boljše razumevanje je priporočljivo, da bralec
bere ta dokument skupaj s standardom ISO/TR 52018-2, točko za točko.

Kazalniki EPB, ki jih je mogoče uporabiti za določitev zahtev za tehnične sisteme v stavbah, so
načeloma zajeti v ustreznih dokumentih EPB (ki so do zdaj večinoma standardi CEN).

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.

OPOMBA 3: 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 delnih zahtev EPB, povezanih z bilanco
toplotne energije in lastnostmi stavbnega tkiva – 1. del: Pregled možnosti


1 Področje uporabe

Nabor standardov za oceno EPB v svojih izhodnih podatkih ustvarja veliko število skupnih in delnih
kazalnikov EPB, ki jih je mogoče uporabiti za različne namene. Ta dokument obravnava uporabo kot
zahtevo delnih kazalnikov EPB v zvezi s stavbnim tkivom in bilanco toplotne energije stavbe. Vidiki
bilance toplotne energije se navezujejo tako na potrebe po ogrevanju in hlajenju kot na temperature v
nekontroliranih pogojih, zlasti v povezavi s pregrevanjem ali prehladnimi notranjimi temperaturami. 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 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.

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.

2 Zveze s standardi

Za uporabo tega dokumenta so, delno ali v celoti, nujni naslednji referenčni dokumenti. Pri datiranih
sklicevanjih se uporablja samo navedena izdaja. Pri nedatiranih sklicevanjih se uporablja zadnja izdaja
referenčnega dokumenta (vključno z morebitnimi dopolnili).

OPOMBA 1: Poleg tega dodatek C vsebuje posebne vzporedne poti s sklicevanjem na standarde, da bi se tako upoštevali
veljavni nacionalni in/ali regionalni predpisi in/ali pravni okviri ob upoštevanju globalnih meril.

OPOMBA 2: Privzeti sklici na standarde EPB, ki niso ISO 52000-1, so opredeljeni s kodno številko modula EPB ter podani v
dodatku A (normativna predloga) in dodatku B (informativna privzeta izbira).

PRIMER: Kodna številka modula EPB: M5-5 ali M5-5.1 (če je modul M5-5 dodatno razdeljen) ali M5-5/1 (če se sklicuje na
določeno točko standarda, ki zajema M5-5).
