This draft standard covers energy performance calculation of mechanical ventilation and air conditioning systems. It takes into account the generation (air handling unit) and distribution (duct system) parts. It does not cover the emission part (calculation of the required volume flow rates and/or supply air conditions), which is covered in prEN 16798-7 (revised EN 15242). A calculation method for compact ventilation systems with integrated heating/cooling generation, using a monthly or seasonal calculation time step, is provided in a separate standard prEN 16798-5-2.

Le présent projet de norme traite du calcul de la performance énergétique des systèmes de ventilation mécanique et de conditionnement d'air. Il prend en compte les aspects relatifs à la génération (caisson de traitement d'air) et à la distribution (système de conduit). Il ne traite pas des aspects relatifs aux émissions (calcul des débits volumiques requis et/ou conditions pour l'air fourni), qui sont traités dans le prEN 16798 7 (révisant l'EN 15242). Une méthode de calcul pour les systèmes de ventilation compacts avec génération de chaleur/froid intégrée, utilisant un pas de calcul mensuel ou saisonnier, est fournie dans une norme séparée, prEN 16798-5-2.

SIST EN 16798-5-1:2018

EN 16798-5-1:2017 (E) 7 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 groups of this standard are all the users of the set of EPB standards (e.g. engineers, regulators, 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 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. 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). Further target groups are parties wanting to motivate their assumptions by classifying the building energy performance for a dedicated building stock. SIST EN 16798-5-1:2018

EN 16798-5-1:2017 (E) 8 More information is provided in the Technical Report accompanying this standard (CEN/TR 16798-6 [1]), including examples aiming to check the quality and usability of the standard. CEN/TC 156 deals with ventilation and air conditioning systems in buildings. Subjects covered by CEN/TC 156 are: a) energy performance calculation for ventilation, air conditioning and cooling systems; b) inspection of ventilation and air conditioning systems; and c) installation and commissioning of ventilation and air conditioning systems. The revision includes changes: — for a rearrangement of content versus EN 15242:2007, in order to better fit in the modular structure given in EN ISO 52000-1; — to cover full air conditioning systems (including heating, cooling humidification, dehumidification; definition see the module M5-1 standard); — for an improved fan energy calculation, taking into consideration control strategies according to CEN/TC 247 and fan product standards/data; — for an improved calculation of different types of heat recovery devices (air-to-air heat exchangers, rotary and pumped circuit), delivering the efficiency and auxiliary energy depending on control, including moisture transfer; — for the consideration of recirculation, including control; — for an improved humidification calculation for different humidifier types, including auxiliary energy; — for the calculation of adiabatic cooling; — the formatting according to the new rules set in CEN/TS 16629; and — the consideration of ISO/TC 205 work performed in the meantime. SIST EN 16798-5-1:2018

EN 16798-5-1:2017 (E) 9 1 Scope This European Standard covers the energy performance calculation of mechanical ventilation and air conditioning systems, including humidification and dehumidification. It takes into account the generation (air handling unit) and distribution (duct system) parts. It includes a simplified calculation of adiabatic cooling systems. It does not cover the emission part (calculation of the required volume flow rates and/or supply air conditions), which is covered in EN 16798-7. It does not include the calculation of heating/cooling generation. This method is focussed on large customized ventilation and air conditioning systems, typically used in commercial buildings, although the application is not restricted on the basis of building or space use type. A calculation method for ventilation systems with integrated heating/cooling generation, including domestic hot water generation, using a monthly or seasonal calculation interval or a bin method, is provided in a separate standard, EN 16798-5-2. This method does not include humidification and dehumidification or adiabatic cooling. 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 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.
