Energy performance of buildings - Ventilation for buildings - Part 3: For non-residential buildings - Performance requirements for ventilation and room-conditioning systems (Modules M5-1, M5-4)

1   Scope
This European Standard applies to the design and implementation of ventilation, air conditioning and room conditioning systems for non-residential buildings subject to human occupancy, excluding applications like industrial processes. It focuses on the definitions of the various parameters that are relevant for such systems.  
The guidance for design given in this standard and accompanying TR 13779 are mainly applicable to mechanical supply and exhaust ventilation systems. Natural ventilation systems or natural parts of hybrid ventilation systems are not covered by this standard. Reference is made to the Technical Report for informative guidance on the design of such systems.
Applications for residential ventilation are not dealt with in this standard. Performance of ventilation systems in residential buildings are dealt with in EN 15665 and CEN/TR 14788.
The classification uses different categories. For some values, examples are given and, for requirements, typical ranges with default values are presented. The default values given in this standard are not normative as such, and should be used where no other values are specified. Classification should always be appropriate to the type of building and its intended use, and the basis of the classification should be explained if the examples given in the standard are not to be used.
NOTE   Different standards may express the categories for the same parameters in a different way, and also the category symbols may be different.

Energetische Bewertung von Gebäuden - Lüftung von Gebäuden - Teil 3: Lüftung von Nichtwohngebäuden -Leistungsanforderungen an Lüftungs- und Klimaanlagen und Raumkühlsysteme (Module M5-1, M5-4)

Diese Europäische Norm gilt für die Planung und Ausführung von Lüftungs  und Klimaanlagen sowie Raumkühlsystemen in Nichtwohngebäuden, die für den Aufenthalt von Menschen bestimmt sind; Anwendungen der Industrie  und Prozesstechnik sind dabei ausgeschlossen. Das Dokument konzentriert sich auf die Definition der verschiedenen Parameter, die für derartige Anlagen relevant sind.
Die in dieser Norm und im beigefügten Technischen Bericht TR 13779 angegebenen Leitlinien für die Planung gelten hauptsächlich für Anlagen mit maschineller Be  und Entlüftung. Natürliche Lüftungssysteme oder natürliche Teile von Hybridlüftungsanlagen sind nicht Gegenstand dieser Norm. Für informative Hinweise zur Auslegung derartiger Anlagen wird auf den Technischen Bericht verwiesen.
Anforderungen an Lüftungsanlagen in Wohngebäuden sind in dieser Norm nicht behandelt. Die Leistung von Lüftungsanlagen in Wohngebäuden ist in EN 15665 und CEN/TR 14788 behandelt.
Bei der Klassifizierung wird eine Einteilung in unterschiedliche Kategorien vorgenommen. Für einige Werte sind Beispiele angegeben, und für Anforderungen sind übliche Bereiche mit Standardwerten angegeben. Die in diesem Dokument angegebenen Standardwerte als solche sind nicht normativ und sollten angewendet werden, wenn keine anderen Werte festgelegt sind. Die Klassifizierung sollte stets dem Typ und der vorgesehenen Nutzung des Gebäudes entsprechen; wenn die in dieser Norm angegebenen Beispiele nicht angewendet werden, sollte die Klassifizierungsgrundlage erläutert werden.
ANMERKUNG   Die Kategorien für die einzelnen Parameter können in unterschiedlichen Normen unterschiedlich benannt sein, und auch die verwendeten Kategoriesymbole können sich voneinander unterscheiden.

Performance énergétique des bâtiments - Ventilation des bâtiments - Partie 3: Pour bâtiments non résidentiels - Exigences de performances pour les systèmes de ventilation et de climatisation (Modules M5-1, M5-4)

La présente Norme européenne s’applique à la conception et à l’implantation de systèmes de ventilation, de conditionnement d'air et de climatisation pour les bâtiments non résidentiels sujets à occupation humaine, à l’exception des applications telles que les processus industriels. Elle porte surtout sur les définitions des divers paramètres pertinents pour de tels systèmes.
Les lignes directrices pour la conception données dans la présente norme, et accompagnant le TR 13779, s'appliquent principalement aux systèmes de ventilation mécanique d’air fourni et rejeté. Les systèmes de ventilation naturelle ou les parties naturelles des systèmes de ventilation hybride ne sont pas traités dans la présente norme. Il est fait référence au Rapport technique concernant des lignes directrices informatives sur la conception de tels systèmes.
Les applications pour la ventilation résidentielle ne sont pas traitées dans la présente norme. La performance des systèmes de ventilation pour les bâtiments résidentiels est couverte par l'EN 15665 et le CEN/TR 14788.
La classification regroupe des catégories différentes. Pour certaines valeurs, des exemples sont fournis, et pour les exigences, des plages types avec des valeurs par défaut sont indiquées. Les valeurs par défaut données dans la présente norme ne sont pas normatives en tant que telles et il convient qu’elles ne soient utilisées que si aucune autre valeur n’est spécifiée. II convient que la classification soit toujours appropriée au type du bâtiment et à son utilisation présumée, et il convient que le fondement de la classification soit expliqué si les exemples donnés dans la norme ne sont pas utilisés.
NOTE   Différentes normes peuvent définir de manière différente des catégories pour les mêmes paramètres et les symboles pour ces catégories peuvent également être différents.

Energijske lastnosti stavb - Prezračevanje stavb - 3. del: Prezračevanje nestanovanjskih stavb - Zahtevane lastnosti za sisteme prezračevanja in klimatizacije prostorov - Modula M5-1, M5-4

Ta evropski standard se uporablja za načrtovanje in izvedbo prezračevalnih sistemov, klimatskih naprav in sistemov za klimatizacijo prostorov v nestanovanjskih stavbah za človeško uporabo, razen aplikacij, kot so industrijski procesi. Osredotoča se na opredelitve različnih parametrov, ki so pomembni za takšne sisteme.  
Smernice za načrtovanje, podane v tem standardu in priloženem tehničnem poročilu TR 13779, se v glavnem uporabljajo za prezračevalne sisteme z mehanskim dovajanjem in odvajanjem. Ta standard ne zajema naravnih prezračevalnih sistemov ali naravnih delov hibridnih prezračevalnih sistemov. Glede informativnih navodil za načrtovanje takšnih sistemov se standard sklicuje na tehnično poročilo.
Ta standard ne obravnava aplikacij za prezračevanje stanovanjskih objektov. Učinkovitost prezračevalnih sistemov v stanovanjskih objektih obravnavata standarda EN 15665 in CEN/TR 14788.
Za razvrščanje se uporabljajo različne kategorije. Za nekatere vrednosti so podani primeri, v zvezi z zahtevami pa so navedeni običajni razponi s privzetimi vrednostmi. Privzete vrednosti, podane v tem standardu, same po sebi niso normativne, zato jih je priporočljivo uporabljati, če druge vrednosti niso določene. Razvrščanje mora biti vedno prilagojeno glede na vrsto in predvideno uporabo stavbe, podlago za razvrščanje pa je treba pojasniti, če se primeri iz standarda ne bodo uporabljali.
OPOMBA: v različnih standardih so lahko kategorije enakih parametrov različno izražene, prav tako se lahko razlikujejo simboli za kategorije.

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 European 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 European Standard are all the users of the set of EPB standards (e.g.
architects, engineers, regulators).
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 European 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 European 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 16798-4).
This European Standard also provides requirements especially for designers, installers, manufacturers,
building owners and users, on ventilation, air-conditioning and room-conditioning systems in order to
achieve a comfortable and healthy indoor environment in all seasons with acceptable installation and
running costs. This European Standard focuses on the system-aspects for typical applications and covers the
following:

negative impact on the quality of the indoor environment.
— Definitions of design and performances data.

EN 16798-3:2017 (E)
1 Scope
This European Standard applies to the design, energy performance of buildings and implementation of
ventilation, air conditioning and room conditioning systems for non-residential buildings subject to human
occupancy, excluding applications like industrial processes. It focuses on the definitions of the various
parameters that are relevant for such systems.
The guidance for design given in this European Standard and accompanying CEN/TR 16798-4 are mainly
applicable to mechanical supply and/or exhaust ventilation systems. Natural ventilation systems or natural
parts of hybrid ventilation systems are not covered by this European Standard. Reference is made to the
Technical Report for informative guidance on the design of such systems.
Applications for residential ventilation are not dealt with in this European Standard. Performance of
ventilation systems in residential buildings are dealt with in EN 15665 and CEN/TR 14788.
The classification uses different categories. For some values, examples are given and, for requirements,
typical ranges with default values are presented. The default values given in this European Standard are not
normative as such, and should be used where no other values are specified. Classification should always be
appropriate to the type of building and its intended use, and the basis of the classification should be
explained if the examples given in the European Standard are not to be used.
NOTE 1 Different standards may express the categories for the same parameters in a different way, and also the
category symbols may be different.
Table 1 shows the relative position of this European Standard within the set of EPB standards in the context
of the modular structure as set out in EN ISO 52000-1.
NOTE 2 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 3 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.

Foreword
This document (prEN 16798-3:2014) has been prepared by Technical Committee CEN/TC 156
“Ventilation for buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association.
This document will supersede EN 13779:2007.
This standard forms part of a series of standards aimed at European harmonisation of the
methodology for the calculation of the energy performance of buildings. An overview of the whole set
of standards is given in CEN/TR 15615, Explanation of the general relationship between various CEN
standards and the Energy Performance of Buildings Directive (EPBD) ("Umbrella document").
Attention is drawn to the need for observance of all relevant EU Directives transposed into national
legal requirements. Existing national regulations with or without reference to national standards, may
restrict for the time being the implementation of the European Standards mentioned in this report.

Introduction
This standard is part of a set of standards developed to support EPBD directive 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 directive.
This standard provides requirements especially for designers, installers, manufacturers, building
owners and users, on ventilation, air-conditioning and room-conditioning systems in order to achieve
a comfortable and healthy indoor environment in all seasons with acceptable installation and running
costs. The standard focuses on the system-aspects for typical applications and covers the following:
 Aspects important to achieve and maintain a good energy performance in the systems without
any negative impact on the quality of the indoor environment.
 Definitions of design and performances data.
This standard was developed during the first EPBD mandate and the first version was published in
2008.
The revision for inclusion in the second mandate package was performed…
The revision concerned mainly the following aspects:
 Update of filtration aspects
 Update of heat recovery aspects
 clear split to EN 15251, outdoor air volume flows have be shifted to EN 15251
 aspects of energy performance have been updated
 The document was split in a normative part, containing all the normative aspects and a
supplementary technical report containing additional information and informative annexes.
 The standard allows a normative national annex
The standard was updated to cover hourly/monthly/seasonal time-step.

1 Scope
This European Standard applies to the design and implementation of ventilation, air conditioning and
room conditioning systems for non-residential buildings subject to human occupancy, excluding
applications like industrial processes. It focuses on the definitions of the various parameters that are
relevant for such systems.
The guidance for design given in this standard and accompanying TR 13779 are mainly applicable to
mechanical supply and exhaust ventilation systems. Natural ventilation systems or natural parts of
hybrid ventilation systems are not covered by this standard. Reference is made to the Technical
Report for informative guidance on the design of such systems.
Applications for residential ventilation are not dealt with in this standard. Performance of ventilation
systems in residential buildings are dealt with in EN 15665 and CEN/TR 14788.
The classification uses different categories. For some values, examples are given and, for
requirements, typical ranges with default values are presented. The default values given in this
standard are not normative as such, and should be used where no other values are specified.
Classification should always be appropriate to the type of building and its intended use, and the basis
of the classification should be explained if the examples given in the standard are not to be used.
NOTE Different standards may express the categories for the same parameters in a different way, and also
the category symbols may be different.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 12792:2003 and the
following apply.
3.1
room conditioning system
system able to keep comfort conditions in a room within a defined range
Note 1 to entry: Air conditioning systems as well as surface based systems are included.
3.2
occupied zone
volume of air that is confined by specified horizontal and vertical planes
Note 1 to entry: Usually the term “occupied zone” is used only for areas designed for human occupancy.
Note 2 to entry: The vertical planes are usually parallel with the walls of the room. Usually there is also a limit
placed on the height of the occupied zone. Thus, the occupied zone in a room is that space in which the
occupants are normally located and where the requirements for the indoor environment shall be satisfied.
Definitions are given in 7.2.
Note 3 to entry: The definition of the occupied zone is dependent on the geometry and the use of the room and
should be specified case by case.
3.3
ventilation effectiveness
relation between the pollution concentrations in the supply air, the extract air and the indoor air in the
breathing zone (within the occupied zone)
3.4
