EN 15316-4-8:2017 (E) 4 European foreword This document (EN 15316-4-8:2017) 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 15316-4-8:2011. The main changes compared to EN 15316-4-8:2011 are: a) Support of hourly methods; b) Compliance with specifications given by CEN/TS 16629; c) Scope extended to stoves and local heaters included in lot 20 of Ecodesign. 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of an identical text or by endorsement, at the latest by October 2017, and conflicting national standards shall be withdrawn at the latest by October 2017.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. 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. SIST EN 15316-4-8:2018
EN 15316-4-8:2017 (E) 5 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. 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, product manufacturers and suppliers, software developers, etc.). 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 15316-6-9). SIST EN 15316-4-8:2018
EN 15316-4-8:2017 (E) 6 The subjects covered by CEN/TC 228 are the following: — design of heating systems (water based, electrical etc.); — installation of heating systems; — commissioning of heating systems; — instructions for operation, maintenance and use of heating systems; — methods for calculation of the design heat loss and heat loads; — methods for calculation of the energy performance of heating systems. Heating systems also include the effect of attached systems such as hot water production systems. All these standards are systems standards, i.e. they are based on requirements addressed to the system as a whole and not dealing with requirements to the products within the system. Where possible, reference is made to other European or International Standards, a. o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. This standard presents methods to take into account the energy performance of heat generation systems based on local air heaters, radiant heaters and stoves. The calculation is based on the performance characteristics of the products given in product standards and on other characteristics required to evaluate the performance of the products as included in the system. This standard covers only the heat generation function of air heaters even though air heaters, as devices, also emit heat and include devices for space heating control. The emission and control function and the related losses are covered by module M3-5. This standard is meant to be used as a module within the EN EPB package of standards. Specification of the connection of this standard with other calculation modules are given in module M3-1 and EN ISO 52000-1. Default references to EPB standards other than EN ISO 52000-1 are identified by the EPB module code number and 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. SIST EN 15316-4-8:2018
EN 15316-4-8:2017 (E) 7 1 Scope This European Standard is part of a series of standards on the method for calculation of system energy requirements and system efficiencies. The scope of this specific part is to standardize the: — required inputs; — calculation method; — resulting outputs, for space heating generation by: — air heating systems, including control; — overhead radiant heating systems for non-domestic use, including control; and — stoves and local heaters for residential use. This standard does not apply to heating systems that utilize water as a heat transfer medium. Other heat generation systems such as boilers, heat pumps and others are covered in other sub modules of M3-8. 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. 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.

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.
The subjects covered by CEN/TC 228 are the following:
design of heating systems (water based, electrical etc.);
installation of heating systems;
commissioning of heating systems;
instructions for operation, maintenance and use of heating systems;
methods for calculation of the design heat loss and heat loads;
methods for calculation of the energy performance of heating systems.
Heating systems also include the effect of attached systems such as hot water production systems.
All these standards are systems standards, i.e. they are based on requirements addressed to the system as a
whole and not dealing with requirements to the products within the system.
Where possible, reference is made to other European or International Standards, a. o. product standards.
However, use of products complying with relevant product standards is no guarantee of compliance with the
system requirements.
The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function
of the system and not specifying shape, material, dimensions or the like.
The guidelines describe ways to meet the requirements, but other ways to fulfil the functional requirements
might be used if fulfilment can be proved.
Heating systems differ among the member countries due to climate, traditions and national regulations. In
some cases requirements are given as classes so national or individual needs may be accommodated.
In cases where the standards contradict with national regulations, the latter should be followed.
This standard presents methods to take into account the energy performance of heat generation systems
based on local air heaters, radiant heaters and stoves. The calculation is based on the performance
characteristics of the products given in product standards and on other characteristics required to evaluate the
performance of the products as included in the system.
This standard is meant to be used as a module within the EN EPB package of standards. Specification of the
connection of this standard with other calculation modules are given in prEN 15316-1:2013 and
prEN 15603:2013. Figure 1 shows the relative position of this standard within the EPB standards.
