Energy performance of buildings - Method for calculation of system energy requirements and system efficiencies - Part 1: General and Energy performance expression, Module M3-1, M3-4, M3-9, M8-1, M8-4

This European Standard is the general frame for the calculation of the energy use and the energy performance of heating and domestic hot water systems. This standards is only dealing with the heat, provided by water based systems, needed for heating, domestic hot water and cooling (e.g. absorption chiller).
It specifies how to perform the calculation of the entire installation using the calculation modules (see Table 2) corresponding to the methods defined in the respective standards.
It deals with common issues like operating conditions calculation and energy performance indicators.
It standardises the inputs and outputs in order to achieve a common European calculation method.
It allows the energy analysis of the heating and Domestic hot water systems and sub-systems including control (emission, distribution, storage, generation) by comparing the system losses and by defining energy performance indicators.
The performance analysis allows the comparison between systems and sub-systems and makes possible to evaluate the impact of each sub-system on the energy performance of a building.
The calculation of the system losses of each part of the heating sub-systems is defined in subsequent standards.
Ventilation systems are not included in this standard (e.g. balanced systems with heat recovery), but if the air is preheated or an air heating system is installed, the systems providing the heat to the AHU (Air Handling Unit) are covered by this standard.
Table 2 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000-1.
NOTE 1   In prCEN 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 2   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.

Energetische Bewertung von Gebäuden - Verfahren zur Berechnung der Energieanforderungen und Nutzungsgrade der Anlagen - Teil 1: Allgemeines und Darstellung der Energieeffizienz, Module M3-1, M3-4, M3-9, M8-1, M8-4

Diese Europäische Norm bildet den allgemeinen Rahmen für die Berechnung der Energienutzung und der Gesamtenergieeffizienz von Raumheizungsanlagen und Trinkwarmwasseranlagen. Diese Norm behandelt ausschließlich die von wasserbasierten Anlagen gelieferte Wärme, die für Heizung, erwärmtes Trinkwasser und Kühlung (z. B. Absorptionskühler) erforderlich ist.
Sie legt fest, wie die Berechnung für die gesamte Installation mithilfe von Berechnungsmodulen (siehe Tabelle 2) entsprechend der in den einschlägigen Normen festgelegten Verfahren durchzuführen ist.
Sie behandelt allgemeine Themen, wie die Berechnung der Betriebsbedingungen, sowie Indikatoren für die Gesamtenergieeffizienz.
Sie vereinheitlicht die Eingabe- und Ausgabegrößen mit dem Ziel, ein einheitliches europäisches Berechnungsverfahren zu erstellen.
Sie ermöglicht die energetische Analyse der Systeme und Teilsysteme der Heizungs- und Trink-warmwasseranlagen, einschließlich der Regelung (Wärmeübergabe, -verteilung, -speicherung, -erzeugung), durch Vergleichen der Systemenergieverluste und durch Festlegen von Energieeffizienzkennwerten.
Die Analyse erlaubt es, die betreffenden Systeme und Teilsysteme miteinander zu vergleichen und die Auswirkungen jedes einzelnen Teilsystems auf die Gesamtenergieeffizienz des Gebäudes zu bewerten.
Die Berechnungsverfahren der Systemenergieverluste jedes Teilsystems der Heizungsanlage sind in den folgenden Normen festgelegt.
Diese Norm umfasst keine Lüftungsanlagen (z. B. ausgeglichene Anlagen mit Wärmerückgewinnung); wird die Luft jedoch vorgewärmt oder ist ein Luftheizsystem eingebaut, so werden die Systeme, die die Wärme für das Luftbehandlungsgerät (AHU, en: Air Handling Unit) liefern, von der vorliegenden Norm abgedeckt.
Tabelle 2 zeigt die relative Position dieser Norm innerhalb des EPB-Normenpakets im Kontext der in prEN ISO 52000-1 dargelegten modularen Struktur.
ANMERKUNG 1   In prCEN ISO/TR 52000-2 findet sich die gleiche Tabelle mit den Nummern (für jedes Modul) der jeweiligen EPB-Normen und den dazugehörigen technischen Berichten, die bereits veröffentlicht wurden oder sich in der Erstellung befinden.
ANMERKUNG 2   Die Module repräsentieren EPB-Normen, auch wenn eine EPB-Norm mehr als ein Modul abdecken kann und ein Modul von mehr als einer EPB-Norm abgedeckt werden kann, zum Beispiel jeweils ein vereinfachtes und ein detailliertes Verfahren. Siehe auch Abschnitt 2 und Tabellen A.1 und B.1.

European foreword
This document (EN 15316-1:2017) has been prepared by Technical Committee CEN/TC 228 “Heating
systems and water based cooling systems”, the secretariat of which is held by DIN.
This document supersedes EN 15316-1:2007.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2017, and conflicting national standards
shall be withdrawn at the latest by October 2017.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association.
The main changes compared to EN 15316-1:2007 are:
— reference and coordination of all other modules (a module corresponds to a subsystem standard);
— inclusion of operating conditions calculation and load dispatching related to building automation
control (BAC) and systems design (e.g. connection of distributions).
— inclusion of a monthly method based on BIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden,
Switzerland, Turkey and the United Kingdom.
Introduction
This Standard is part of a series of standards aiming at international harmonization of the
methodology for the assessment of the energy performance of buildings, called “set of EPB standards”.
EPB standards deal with energy performance calculation and other related aspects (like system sizing)
to provide the building services considered in the EPB Directive.
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 standard a normative template is given in Annex A to specify these choices.
Informative default choices are provided in Annex B.
Use by or for regulators: In case the standard 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 this Annex A) can be made
available as national annex or as separate (e.g. legal) document (national data sheet).
NOTE So in this case:
— the regulators will specify the choices;
— the individual user will apply the standard to assess the energy performance of a building, and
thereby use the choices made by the regulators.
Topics addressed in this standard can be subject to public regulation. Public regulation on the same
topics can override the default values in Annex B of this standard. Public regulation on the same topics
can even, for certain applications, override the use of this standard. 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 the national annex (e.g. NA) refers
to this text;
— 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 standard
(CEN/TR 15316-6-1).
CEN/TC 228 deals with heating systems and water based cooling systems in buildings. Subjects
covered by TC 228 are:
— energy performance calculation;
— inspection;
— design of systems;
— installation and commissioning.
The first version of this standard was developed during the first EPBD mandate and published in 2008.
The revision for inclusion in the second EPBD mandate package was performed in 2014.
Default references to EPB standards other than EN ISO 52000-1 are identified by the EPB module code
number and given an Annex A (normative template) and Annex B (informative default choice).
Table 1 associates the title of the EN EPB standards to the numbers and modules. It also remembers
the replaced standards.

1 Scope
This European Standard is the general frame for the calculation of the energy use and the energy
performance of heating and domestic hot water systems. This standards is only dealing with the heat,
provided by water based systems, needed for heating, domestic hot water and cooling (e.g. absorption
chiller).
It specifies how to perform the calculation of the entire installation using the calculation modules (see
Table 2) corresponding to the methods defined in the respective standards.
It deals with common issues like operating conditions calculation and energy performance indicators.
It standardises the inputs and outputs in order to achieve a common European calculation method.
It allows the energy analysis of the heating and Domestic hot water systems and sub-systems including
control (emission, distribution, storage, generation) by comparing the system losses and by defining
energy performance indicators.
The performance analysis allows the comparison between systems and sub-systems and makes
possible to evaluate the impact of each sub-system on the energy performance of a building.
The calculation of the system losses of each part of the heating sub-systems is defined in subsequent
standards.
Ventilation systems are not included in this standard (e.g. balanced systems with heat recovery), but if
the air is preheated or an air heating system is installed, the systems providing the heat to the AHU
(Air Handling Unit) are covered by this standard.
Table 2 shows the relative position of this standard within the set of EPB standards in the context of
the modular structure as set out in EN ISO 52000-1.
NOTE 1 In CEN 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 2 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.
