Introduction
The set of EPB standards, technical reports and supporting tools:
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, 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, 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 a 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, EN ISO 52000-1:2017.
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 high 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 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 [2]),
— to avoid flooding and confusing the actual normative part with informative content,
6

---------------------- Page: 8 ----------------------

SIST-TP CEN/TR 15378-4:2018
CEN/TR 15378-4:2017 (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 [4] that laid the
foundation for the preparation of the set of EPB standards.
This Technical Report:
This Technical Report accompanies the standard EN 15378-3:2017 on the assessment of measure
measured delivered energy for space heating and domestic hot water preparation.
The first part of this Technical Report, up to Clause 13 and all annexes up to Annex D have the same
numbering as EN 15378-3:2017. Each clause in this CEN/TR 15378-4 is related to the same clause in
EN 15378-3:2017.
The role and the positioning of the accompanied standard(s) in the set of EPB standards is defined in
the Introduction to the standard.
Accompanying spreadsheet(s):
Concerning the accompanied standard EN 15378-3:2017, the following spreadsheets were produced:
— one spreadsheet on space heating measured delivered energy assessment using the seasonal data
interpolation method (see 6.8);
— one spreadsheet on space heating measured delivered energy assessment using the energy
signature method (see 6.9);
— one spreadsheet on domestic hot water measured delivered energy assessment;
— one spreadsheet on boiler efficiency assessment, both combustion efficiency and seasonal
efficiency.
In this Technical Report, two examples of space heating measured delivered energy assessment are
included.
History of this Technical Report and the accompanied standard:

Introduction
The set of EPB standards, technical reports and supporting tools
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 a 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 high 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 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 [2]),
— 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 [4] that laid the
foundation for the preparation of the set of EPB standards.
This Technical Report
This Technical Report accompanies the standard prEN 15378-3:2014 on the assessment of measure
measured delivered energy for space heating and domestic hot water preparation.
The first part of this Technical Report, up to Clause 13 and all annexes up to Annex D have the same
numbering as prEN 15378-3:2014. Each clause in this FprCEN/TR 15378-4 is related to the same clause
in prEN 15378-3:2014.
The role and the positioning of the accompanied standard(s) in the set of EPB standards is defined in
the Introduction to the standard.
Accompanying spreadsheet(s)
Concerning the accompanied standard prEN 15378-3:2014, the following spreadsheets were produced:
— one spreadsheet on space heating measured delivered energy assessment using the seasonal data
interpolation method (see 6.8);
— one spreadsheet on space heating measured delivered energy assessment using the energy
signature method (see 6.9);
— one spreadsheet on domestic hot water measured delivered energy assessment;
— one spreadsheet on boiler efficiency assessment, both combustion efficiency and seasonal
efficiency.
In this Technical Report, two examples of space heating measured delivered energy assessment are
included.
History of this Technical Report and the accompanied standard
prEN 15378-3:2014 is the first version of a standard on measured energy performance. It includes
provisions already
