Le présent Rapport technique se rapporte à l’EN 15316 1:2017, modules M3-1, M8-1, M3-4, M8-4, M3 9, M8-9.
Il contient des informations pour aider à la compréhension, l’utilisation et l’adaptation nationale correctes de l’EN 15316 1:2017.
Le présent Rapport technique ne contient aucune disposition normative.
La norme associée EN 15316 1:2017 est le cadre général pour le calcul de la consommation d’énergie et de la performance énergétique des systèmes de chauffage et de production d’eau chaude sanitaire. La présente norme traite uniquement de la chaleur, fournie par les systèmes à eau, nécessaire pour le chauffage, l’eau chaude sanitaire et le refroidissement (refroidisseur à absorption par exemple).
Elle spécifie comment réaliser le calcul de l’ensemble de l’installation en utilisant les modules de calcul (voir Figure 1) correspondant aux méthodes définies dans les normes respectives.
Elle traite des problèmes communs tels que le calcul des conditions de fonctionnement et les indicateurs de performance énergétique.
Elle normalise les données d’entrée et de sortie, afin d’obtenir une méthode de calcul commune au niveau européen.
Elle permet l’analyse énergétique des systèmes et sous-systèmes de chauffage et de production d’eau chaude sanitaire, y compris leur régulation (émission, distribution, stockage, génération) en comparant les pertes du système et en définissant les indicateurs de performance énergétique.
Cette analyse de performance permet de comparer les systèmes et les sous-systèmes et d’évaluer l’impact de chaque sous-système sur la performance énergétique d’un bâtiment.
Le calcul des pertes de chaque partie des sous-systèmes de chauffage est défini dans les normes suivantes.
Les systèmes de ventilation ne sont pas compris dans la présente norme (par exemple, les systèmes double flux avec récupération de chaleur), mais si l’air est préchauffé ou si un système de chauffage de l’air est installé, les systèmes fournissant la chaleur à l’unité de traitement d’air sont couverts par la présente norme.

Introduction
The CENSE project, the discussions between CEN and the Concerted action highlighted the high page
count of the entire package due to a lot of “textbook” information. This resulted in flooding and
confusing the normative text.
In order to facilitate the necessary overall consistency and coherence, in terminology, approach,
input/output relations and formats, for the whole set of EPB-standards, the following documents and
tools are available:
a) a document with basic principles to be followed in drafting EPB-standards:
CEN/TS 16628:2014, Energy Performance of Buildings - Basic Principles for the set of EPB
standards [1];
b) a document with detailed technical rules to be followed in drafting EPB-standards;
CEN/TS 16629:2014, Energy Performance of Buildings - Detailed Technical Rules for the set of
EPB-standards [2];
c) the detailed technical rules are the basis for the following tools:
1) a common template for each EPB-standard, including specific drafting instructions for the
relevant clauses;
2) a common template for each technical report that accompanies an EPB standard or a cluster of
EPB standards, including specific drafting instructions for the relevant clauses;
3) a common template for the spreadsheet that accompanies each EPB standard, to demonstrate
the correctness of the EPB calculation procedures.
Each EPB-standards follows the basic principles and the detailed technical rules and relates to the
overarching EPB-standard, prEN ISO 52000-1:2015.
One of the main purposes of the revision of the EPB-standards is to enable that laws and regulations
directly refer to the EPB-standards and make compliance with them compulsory. This requires that the
set of EPB-standards consists of a systematic, clear, comprehensive and unambiguous set of energy
performance procedures. The number of options provided is kept as low as possible, taking into
account national and regional differences in climate, culture and building tradition, policy and legal
frameworks (subsidiarity principle). For each option, an informative default option is provided
(Annex B).
Rationale behind the EPB technical reports
There is a risk that the purpose and limitations of the EPB standards will be misunderstood, unless the
background and context to their contents – and the thinking behind them – is explained in some detail
to readers of the standards. Consequently, various types of informative contents are recorded and made
available for users to properly understand, apply and nationally or regionally implement the EPB
standards.
If this explanation would have been attempted in the standards themselves, the result is likely to be
confusing and cumbersome, especially if the standards are implemented or referenced in national or
regional building codes.
Therefore each EPB standard is accompanied by an informative technical report, like this one, where all
informative content is collected, to ensure a clear separation between normative and informative
contents (see CEN/TS 16629):
- to avoid flooding and confusing the actual normative part with informative content,

CEN/TR 15316-6-1:2017 (E)
- to reduce the page count of the actual standard, and
- to facilitate understanding of the set of EPB standards.
This was also one of the main recommendations from the European CENSE project [1] that laid the
foundation for the preparation of the set of EPB standards.
Figure 1 shows the relative position of the related standard within the EPB package of standards and
the position of all the other EPB standards under the responsibility of CEN/TC 228.

Introduction
The CENSE project, the discussions between CEN and the Concerted action highlighted the high page
count of the entire package due to a lot of “textbook” information. This resulted in flooding and
confusing the normative text.
In order to facilitate the necessary overall consistency and coherence, in terminology, approach,
input/output relations and formats, for the whole set of EPB-standards, the following documents and
tools are available:
a) a document with basic principles to be followed in drafting EPB-standards:
CEN/TS 16628:2014, Energy Performance of Buildings - Basic Principles for the set of EPB
standards [1];
b) a document with detailed technical rules to be followed in drafting EPB-standards;
CEN/TS 16629:2014, Energy Performance of Buildings - Detailed Technical Rules for the set of
EPB-standards [2];
c) the detailed technical rules are the basis for the following tools:
1) a common template for each EPB-standard, including specific drafting instructions for the
relevant clauses;
2) a common template for each technical report that accompanies an EPB standard or a cluster of
EPB standards, including specific drafting instructions for the relevant clauses;
3) a common template for the spreadsheet that accompanies each EPB standard, to demonstrate
the correctness of the EPB calculation procedures.
Each EPB-standards follows the basic principles and the detailed technical rules and relates to the
overarching EPB-standard, prEN ISO 52000-1:2015.
One of the main purposes of the revision of the EPB-standards is to enable that laws and regulations
directly refer to the EPB-standards and make compliance with them compulsory. This requires that the
set of EPB-standards consists of a systematic, clear, comprehensive and unambiguous set of energy
performance procedures. The number of options provided is kept as low as possible, taking into
account national and regional differences in climate, culture and building tradition, policy and legal
frameworks (subsidiarity principle). For each option, an informative default option is provided
(Annex B).
Rationale behind the EPB technical reports
There is a risk that the purpose and limitations of the EPB standards will be misunderstood, unless the
background and context to their contents – and the thinking behind them – is explained in some detail
to readers of the standards. Consequently, various types of informative contents are recorded and made
available for users to properly understand, apply and nationally or regionally implement the EPB
standards.
If this explanation would have been attempted in the standards themselves, the result is likely to be
confusing and cumbersome, especially if the standards are implemented or referenced in national or
regional building codes.
Therefore each EPB standard is accompanied by an informative technical report, like this one, where all
informative content is collected, to ensure a clear separation between normative and informative
contents (see CEN/TS 16629):
- to avoid flooding and confusing the actual normative part with informative content,

- to reduce the page count of the actual standard, and
- to facilitate understanding of the set of EPB standards.
This was also one of the main recommendations from the European CENSE project [1] that laid the
foundation for the preparation of the set of EPB standards.
Figure 1 shows the relative position of the related standard within the EPB package of standards and
the position of all the other EPB standards under the responsibility of CEN/TC 228.
