Energy performance of buildings - Ventilation for buildings - Part 13: Calculation of cooling systems (Module M4-8) - Generation
This European Standard covers the calculation of the operational parameters and the energy consumption of cooling generation systems. The cooling generation consists of:
- cooling generators like compression and absorption chillers;
- other (generic) generator types such as ground or surface water or direct use of ground heat from boreholes; and
- different types of heat rejection (dry, wet, hybrid with outdoor air, other sink types).
The methods cover:
- the possibility of heat recovery of heat to be rejected for the use of heating and/or domestic hot water production, through the use of an interface to the M3-1 standard; and
- a multi generator calculation.
The document does not cover the cooling emission, distribution and storage systems, which are covered by the Module M4-5, M4-6 and M4-7 standards, respectively. It is directly connected to the general part of the cooling systems, the M4-1 standard.
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 prEN ISO 52000 1:2015.
NOTE 1 In FprCEN 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 might cover more than one module and one module might 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.

EN 16798-13:2017 (E) 7 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 groups of this standard are all the users of the set of EPB standards (e.g. engineers, regulators and programmers). 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 16798-14 [2], under preparation). EPB standards deal with energy performance calculation and other related aspects (like system sizing) to provide the building services considered in the EPBD. SIST EN 16798-13:2018
EN 16798-13:2017 (E) 8 TC 156 deals with ventilation and air conditioning systems in buildings. Subjects covered by TC 156 are: — cooling load calculation; — energy performance calculation for ventilation, air conditioning, and cooling systems; — inspection of ventilation and air conditioning systems; and — installation and commissioning of ventilation and air conditioning systems. This standard specifies a method to calculate the cooling generation of compression, absorption and other types of refrigeration systems. This standard extends EN 15243:2007, which was developed during the first EPBD mandate. The extension for inclusion in the second mandate package was performed by CEN/TC 156 WG 21. SIST EN 16798-13:2018
EN 16798-13:2017 (E) 9 1 Scope This European Standard covers the calculation of the operational parameters and the energy consumption of cooling generation systems. The cooling generation consists of: — cooling generators like compression and absorption chillers; — other (generic) generator types such as ground or surface water or direct use of ground heat from boreholes; and — different types of heat rejection (dry, wet, hybrid with outdoor air, other sink types). The methods cover: — the possibility of heat recovery of heat to be rejected for the use of heating and/or domestic hot water production, through the use of an interface to the M3-1 standard; and — a multi generator calculation. The document does not cover the cooling emission, distribution and storage systems, which are covered by the Module M4-5, M4-6 and M4-7 standards, respectively. It is directly connected to the general part of the cooling systems, the M4-1 standard. 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 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 might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
