European foreword
This document (EN 15378-3:2017) has been prepared by Technical Committee CEN/TC 228 “Heating
systems and water based cooling systems in buildings”, the secretariat of which is held by DIN.
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be withdrawn at the latest by October 2017.
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.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
According to the CEN-CENELEC Internal Regulations, the national standards organizations 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 “.
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.
The main target group of this standard are all the users of the set of EPB standards (e.g. architects,
engineers, regulators).
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 1 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 users of the voluntary common European Union certification scheme for the
energy performance of non-residential buildings (EPBD art.11.9) and any other Pan EU 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 15378-
4:2017).
TC 228 deals with heating systems in buildings. Subjects covered by TC 228 are:
— energy performance calculation for heating systems;
— inspection of heating systems;
— design of heating systems;
— installation and commissioning of heating systems.
This is a new standard developed during mandate M480. It incorporates provisions previously stated in
EN 15603:2008 and EN 15378:2008.
Default references to EPB standards other than EN ISO 52000-1:2017 are identified by the EPB module
code number and they are given in Annex A (normative template) and Annex B (informative default
choice).
NOTE 2 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).
1 Scope
This European Standard specifies methods to assess the delivered energy for space heating and
domestic hot water energy performance of a building based on measurements during the operation and
occupancy phase. This includes:
— assessment of the amount of delivered energy carriers for space heating and domestic hot water
preparation based on measurement;
— assessment of the energy performance indicators of heating and domestic hot water systems and
subsystems based on measurements.
This standard does not cover the measurement of delivered energy for ventilation, cooling, air
conditioning and lighting systems.
This standard includes procedures to correct measured delivered energy according to climate and
building use.
Weighting (e.g. conversion into primary energy, cost, CO emission) of the measured delivered energy
and assessment of the energy performance are covered in EN ISO 52000-1:2017.
Table 1 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 52000-1:2017.
NOTE 1 In CEN ISO/TR 52000-2:2017 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.

5 Description of the methods
5.1 Available procedures
This standard includes the following procedures:
— assessment of measured delivered energy for space heating and domestic hot water;
— assessment of measured boiler combustion efficiency;
— assessment of measured seasonal boiler efficiency;
— assessment of measured seasonal domestic hot water system efficiency.
and information on other measurement methods.
5.2 Assessment of measured heating and domestic hot water delivered energy
5.2.1 Output of the method
This method covers the assessment of measured delivered energy for space heating and/or domestic
hot water production.
The output is the amount of delivered and exported energy carriers E and E
del;meas;cr,i exp;meas;cr,i
5.2.2 Optional procedures
This standard includes procedures to adjust the measured actual delivered energy according to
reference climate and/or conditions of use. The delivered energy is evaluated by energy carrier and,
where applicable, by service. The weighting according to weighting factors (e.g. primary energy, CO
emissions) is covered in EN ISO 52000-1:2017.
The procedure consists of the following sequence with the specified alternatives for each step:
1) getting the amount of delivered and exported energy carriers:
i) meters readings;
ii) invoice analysis;
iii) other delivered energy estimation techniques;
2) getting data about corresponding boundary conditions (building use, climate) etc.
3) separating other uses and services than space heating;
4) separating domestic hot water from other uses;
5) applying correction procedures for user behaviour and climate;
i) degree days correlation;
ii) energy signature;
iii) domestic hot water volume;
6) validating the data;
7) reporting.
NOTE Measured energy rating is also referred to as “operational rating”.
5.2.3 Validation of measured delivered energy assessment
Measured delivered energy assessment is valid only if all specified conditions are satisfied (e.g. number
of available measurements, source of data, results validation criteria, etc.).
If the measured delivered energy assessment is not valid, new measurements shall be performed.
if the assessment of measured energy performance is envisaged, this should be taken into account at
design stage of the heating system: the necessary instruments should be installed and recording
procedures should be applied. Otherwise it is not likely that data of acceptable quality will be found to
obtain a valid measured delivered energy assessment.
5.2.4 Correction according to standard use and/or climate
Depending on the correction applied, the measured delivered energy is qualified with the identifier
MEAS_TYPE as defined in Table 4
Table 4 — Identifier for the type of measured delivered energy assessment
Name Identifier value Description
Actual MEAS_TYPE_ACTUAL no correction is applied to the measured
delivered energy;
Climate MEAS_TYPE_CORR_CLIM the actual measured delivered energy was
corrected corrected to the expected delivered energy
with a standard (or specified) climate;
Use MEAS_TYPE_CORR_USE the actual measured delivered energy was
corrected corrected to the expected delivered energy
with a standard (or specified) use;
Standard MEAS_TYPE_STAND the actual measured delivered energy was
corrected to the expected delivered energy
