Energy performance of buildings - Method for calculation of system energy requirements and system efficiencies - Part 4-2: Space heating generation systems, heat pump systems, Module M3-8-2, M8-8-2

The standard covers heat pumps for space heating, heat pump water heaters (HPWH) and heat pumps with combined space heating and domestic hot water production in alternate or simultaneous operation, where the same heat pump delivers the heat to cover the space heating and domestic hot water heat requirement.
The standard provides a calculation method under steady conditions that corresponds to one calculation step.
The results of this calculation are incorporated in larger building models and take in account the influence of the external conditions and building control that influence the energy requirements for heating supplied by the heat pump system.
The scope of this part is to standardise the:
-   required inputs;
-   calculation methods;
-   required outputs
for output thermal power generation for space heating and domestic hot water production of the following heat pump systems, including control:
-   electrically-driven vapour compression cycle (VCC) heat pumps;
-   combustion engine-driven vapour compression cycle heat pumps;
-   thermally-driven vapour absorption cycle (VAC) heat pumps,
using combinations of heat source and heat distribution listed in Table 1.
This standard does not cover sizing or inspection of heat pumps.
This standard deals with heat generators for heating or for combined domestic hot water and heating service. Generators for domestic hot water only are taken into account into module M8-8.
NOTE 1   Heat pumps generators for cooling systems are taken into account into module M4-8.
NOTE 2   Heat pumps generators for space heating using air (distribution) are taken into account in module M5-8.
Other generation systems such as boilers are covered in other sub modules of part M3-8.
This is the revision of EN 15316-4-2:2008. The revision covers the adaptation of the standard to hourly and monthly energy calculation.

European foreword
This document (EN 15316-4-2:2017) 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 document supersedes EN 15316-4-2:2008.
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.
The revision keeps the main principles of the calculation unchanged but the structure of the document
was changed. Informative content was removed to the accompanying technical report CEN/TR 15316-
6-2. The provisions cover also other energy carriers than heat now. The values may be altered in a
national annex.
Calculation methods to determine energy source indicators like the renewable energy ratio have been
added.
The main changes compared to EN 15316-4-2:2008 are:
a) type of heat pumps are now limited to hot water production at the output of the condenser;
b) informative content was removed to the accompanying technical report CEN/TR 15316-6-2;
c) calculation for performance of the heat pumps at different conditions is based on interpolation
provisions;
d) input data for energy performance of the heat pumps are based on part load and/or full load
information;
e) Annex A contains a template for the data and parameters used in the standards and Annex B a set of
default values.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
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 includes the corrigendum EN 15316-4-2:2017/AC:2017 which corrects Table D.3.
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,

Introduction
This European 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.
EPB standards deal with energy performance calculation and other related aspects (like system sizing)
to provide the building services considered in the EPBD.
CEN/TC 228 deals with heating systems in buildings. Subjects covered by CEN/TC 228 are:
— energy performance calculation for heating systems;
— inspection of heating systems;
— design of heating systems;
— installation and commissioning of heating systems.
This standard specifies to take into account the energy performance of heat pump systems used for
domestic or heating purpose.
For the correct use of this standard, Annex A is to be used to specify the choices with the required input
data. Default values are presented in Annex B. 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, in particular for the application within the context of EU Directives transposed
into national legal requirements. These choices can be made available as National Annex or as separate
(e.g. legal) document. It is expected, if the default values and choices in Annex A are not followed due to
national regulations, policy or traditions, that:
— either the national standardization body will consider the possibility to add or include a National
Annex in agreement with the template of Annex A.
— or the national or regional authorities will, in the building regulations, reference the standard and
prepare data sheets containing the national or regional choices and values, in agreement with the
template of Annex A.
This updated standard covers hourly, monthly, annual time-steps and temperatures classes (bin
method).

1 Scope
This European Standard covers heat pumps for space heating, heat pump water heaters (HPWH) and
heat pumps with combined space heating and domestic hot water production in alternate or
simultaneous operation, where the same heat pump delivers the heat to cover the space heating and
domestic hot water heat requirement.
The standard provides a calculation method under steady conditions that corresponds to one
calculation step.
The results of this calculation are incorporated in larger building models and take in account the
influence of the external conditions and building control that influence the energy requirements for
heating supplied by the heat pump system.
The scope of this part is to standardize the:
— required inputs;
— calculation methods;
— required outputs
Generation for space heating and domestic hot water production of the following heat pump systems,
including control of:
— electrically-driven vapour compression cycle (VCC) heat pumps;
— combustion engine-driven vapour compression cycle heat pumps;
— thermally-driven vapour absorption cycle (VAC) heat pumps,
using combinations of heat source and heat distribution listed in Table 1.

Other generation systems such as boilers are covered in other sub modules of part M3-8.
This is the revision of EN 15316-4-2:2008. The revision covers the adaptation of the standard to hourly
and monthly energy calculation.
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 3 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 4 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.

European foreword
This document (EN 15316-4-2:2017) 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 document supersedes EN 15316-4-2:2008.
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.
The revision keeps the main principles of the calculation unchanged but the structure of the document
was changed. Informative content was removed to the accompanying technical report CEN/TR 15316-
6-2. The provisions cover also other energy carriers than heat now. The values may be altered in a
national annex.
Calculation methods to determine energy source indicators like the renewable energy ratio have been
added.
The main changes compared to EN 15316-4-2:2008 are:
a) type of heat pumps are now limited to hot water production at the output of the condenser;
b) informative content was removed to the accompanying technical report CEN/TR 15316-6-2;
c) calculation for performance of the heat pumps at different conditions is based on interpolation
provisions;
d) input data for energy performance of the heat pumps are based on part load and/or full load
information;
e) Annex A contains a template for the data and parameters used in the standards and Annex B a set of
default values.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
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,

Introduction
This European 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.
EPB standards deal with energy performance calculation and other related aspects (like system sizing)
to provide the building services considered in the EPBD.
CEN/TC 228 deals with heating systems in buildings. Subjects covered by CEN/TC 228 are:
— energy performance calculation for heating systems;
— inspection of heating systems;
— design of heating systems;
— installation and commissioning of heating systems.
This standard specifies to take into account the energy performance of heat pump systems used for
domestic or heating purpose.
For the correct use of this standard, Annex A is to be used to specify the choices with the required input
data. Default values are presented in Annex B. 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, in particular for the application within the context of EU Directives transposed
into national legal requirements. These choices can be made available as National Annex or as separate
(e.g. legal) document. It is expected, if the default values and choices in Annex A are not followed due to
national regulations, policy or traditions, that:
— either the national standardization body will consider the possibility to add or include a National
Annex in agreement with the template of Annex A.
— or the national or regional authorities will, in the building regulations, reference the standard and
prepare data sheets containing the national or regional choices and values, in agreement with the
template of Annex A.
This updated standard covers hourly, monthly, annual time-steps and temperatures classes (bin
method).

1 Scope
This European Standard covers heat pumps for space heating, heat pump water heaters (HPWH) and
heat pumps with combined space heating and domestic hot water production in alternate or
simultaneous operation, where the same heat pump delivers the heat to cover the space heating and
domestic hot water heat requirement.
The standard provides a calculation method under steady conditions that corresponds to one
calculation step.
The results of this calculation are incorporated in larger building models and take in account the
influence of the external conditions and building control that influence the energy requirements for
heating supplied by the heat pump system.
The scope of this part is to standardize the:
— required inputs;
— calculation methods;
— required outputs
Generation for space heating and domestic hot water production of the following heat pump systems,
including control of:
— electrically-driven vapour compression cycle (VCC) heat pumps;
— combustion engine-driven vapour compression cycle heat pumps;
— thermally-driven vapour absorption cycle (VAC) heat pumps,
using combinations of heat source and heat distribution listed in Table 1.

This standard does not cover sizing or inspection of heat pumps.
This standard deals with heat generators for heating or for combined domestic hot water and heating
service. Generators for domestic hot water only are taken into account into module M8-8.
NOTE 1 Heat pumps for cooling systems are taken into account into module M4–8.
NOTE 2 Heat pumps for space heating using air (distribution) are taken into account in module M5–8.

Other generation systems such as boilers are covered in other sub modules of part M3-8.
This is the revision of EN 15316-4-2:2008. The revision covers the adaptation of the standard to hourly
and monthly energy calculation.
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 3 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 4 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.

Introduction
1)
This standard is part of a package developed to support EPBD implementation, hereafter called “EPB
standards”.
EPB standards deal with energy performance calculation and other related aspects (like system sizing) to
provide the building services considered in the EPBD.
CEN/TC 228 deals with heating systems in buildings. Subjects covered by CEN/TC 228 are:
 energy performance calculation for heating systems;
 inspection of heating systems;
 design of heating systems;
 installation and commissioning of heating systems.
This standard specifies to take into account the energy performance of heat pump systems used for domestic
or heating purpose.
This updated standard covers hourly and monthly time-step.

1 Scope
The standard covers heat pumps for space heating, heat pump water heaters (HPWH) and heat pumps with
combined space heating and domestic hot water production in alternate or simultaneous operation, where the
same heat pump delivers the heat to cover the space heating and domestic hot water heat requirement.
The standard provides a calculation method under steady conditions that corresponds to one calculation step.
The results of this calculation are incorporated in larger building models and take in account the influence of
the external conditions and building control that influence the energy requirements for heating supplied by the
heat pump system.
The scope of this part is to standardise the:
 required inputs;
 calculation methods;
 required outputs
for output thermal power generation for space heating and domestic hot water production of the following heat
pump systems, including control:
 electrically-driven vapour compression cycle (VCC) heat pumps;
 combustion engine-driven vapour compression cycle heat pumps;
 thermally-driven vapour absorption cycle (VAC) heat pumps,
using combinations of heat source and heat distribution listed in Table 1.

This standard does not cover sizing or inspection of heat pumps.
This standard deals with heat generators for heating or for combined domestic hot water and heating service.
Generators for domestic hot water only are taken into account into module M8-8.
NOTE 1 Heat pumps generators for cooling systems are taken into account into module M4-8.
NOTE 2 Heat pumps generators for space heating using air (distribution) are taken into account in module M5-8.
Other generation systems such as boilers are covered in other sub modules of part M3-8.
