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)

This document 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 document 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 document. Reference is made to the WI 00156243 (under development).
Applications for residential ventilation are not covered in this document. Performance of ventilation systems in residential buildings are covered 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 are given in Annex B and a template for national specification is given in Annex A. 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 can express the categories for the same parameters in a different way, and also the category symbols can be different.
Table 1 shows the relative position of this document 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 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 Table A.1 and Table B.1.

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

Dieses Dokument gilt für die Planung, Energieeffizienz von Gebäuden und Ausführung von Lüftungs- und Klimaanlagen sowie Raumkühlsystemen in Nichtwohngebäuden, die für den Aufenthalt von Menschen bestimmt sind; Anwendungen in 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 diesem Dokument und im zugehörigen Technischen Bericht CEN/TR 16798 4 angegebenen Leitlinien für die Planung gelten hauptsächlich für Anlagen mit maschineller Be- und/oder Entlüftung. Natürliche Lüftungsanlagen oder natürliche Teile von Hybridlüftungsanlagen sind nicht Gegenstand dieses Dokuments. Es wird auf WI 00156243 (in Entwicklung) verwiesen.
Anforderungen an Lüftungsanlagen von Wohngebäuden werden in diesem Dokument nicht behandelt. Die Leistung von Lüftungsanlagen in Wohngebäuden wird 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 aufgeführt. Die Standardwerte sind in Anhang B aufgeführt und eine Vorlage für die nationale Spezifikation ist in Anhang A enthalten. Die Klassifizierung sollte stets dem Typ und der vorgesehenen Nutzung des Gebäudes entsprechen; wenn die in dieser Europäischen Norm angegebenen Beispiele nicht angewendet werden, sollte die Klassifizierungsgrundlage erläutert werden.
ANMERKUNG 1   Die Kategorien für die einzelnen Parameter können in unterschiedlichen Normen unterschiedlich benannt sein, und auch die verwendeten Kategoriesymbole können sich voneinander unterscheiden.
Tabelle 1 zeigt die relative Position dieses Dokuments innerhalb des EPB-Normenpakets im Kontext der in EN ISO 52000 1 dargelegten modularen Struktur.
ANMERKUNG 2   Dieselbe Tabelle ist in CEN ISO/TR 52000 2 zu finden; sie enthält für jedes Modul die Nummern der relevanten EPB-Normen und der zugehörigen Technischen Berichte, die bereits veröffentlicht oder in Vorbereitung sind.
ANMERKUNG 3   Die Module stellen EPB-Normen dar, auch wenn eine EPB-Norm mehr als ein Modul abdecken könnte und ein Modul von mehr als einer EPB-Norm abgedeckt sein könnte, wie es sich zum Beispiel bei einem vereinfachten und einem detaillierteren Verfahren verhält. Siehe auch Abschnitt 2 und Tabelle A.1 und Tabelle B.1.

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)

Le présent document s’applique à la conception, à la performance énergétique des bâtiments 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. Il se concentre sur les définitions des divers paramètres pertinents pour de tels systèmes.
Les lignes directrices pour la conception données dans le présent document et dans le CEN/TR 16798 4 associé s'appliquent principalement aux systèmes de ventilation mécanique de soufflage et/ou d’extraction. Les systèmes de ventilation naturelle ou les parties naturelles des systèmes de ventilation hybride ne sont pas traités dans le présent document. Il est fait référence au WI 00156243 (en cours d’élaboration).
Les applications pour la ventilation résidentielle ne sont pas traitées dans le présent document. La performance des systèmes de ventilation dans les bâtiments résidentiels est couverte par l’EN 15665 et le CEN/TR 14788.
La classification utilise différentes catégories. Pour certaines valeurs, des exemples sont donnés et, pour les exigences, des plages types avec des valeurs par défaut sont présentées. Les valeurs par défaut sont données à l’Annexe B et un modèle de spécification nationale est donné à l’Annexe A. II convient que la classification soit toujours appropriée au type du bâtiment et à son utilisation prévue, et il convient que le fondement de la classification soit expliqué si les exemples donnés dans la Norme européenne ne sont pas utilisés. II convient que la classification soit toujours appropriée au type du bâtiment et à son utilisation prévue, et il convient que le fondement de la classification soit expliqué si les exemples donnés dans la Norme européenne ne sont pas utilisés.
NOTE 1   Différentes normes peuvent définir les catégories pour les mêmes paramètres de manière différente, et les symboles pour ces catégories peuvent également être différents.
Le Tableau 1 indique la position relative du présent document dans l’ensemble de normes PEB dans le cadre de la structure modulaire donnée dans l'EN ISO 52000 1.

European foreword
This document (prEN 16798-3:2022) 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 will supersede EN 16798-3:2017.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association.
In comparison with the previous edition, the following changes have been made:
— New structure to clarify designing and calculation aspects;
— Update of filtration aspects;
— Update of heat recovery aspects and leakages in these systems;
— Aspects of energy performance have been updated;
— Update of definitions of systems;
— Update of SPF definitions and links to EU 327/2014 Regulation;
— An informative Annex C was added for additional design aspects which has been shifted from
CEN/TR 16798-4;
— The standard allows a normative national annex.
EN 16798-3:2017 was produced to meet the requirements of Directive 2002/91/EC 16 December 2002
on energy performance of buildings referred to as “EPBD”.
This document has been produced to meet the requirements of Directive 2010/31/EU 19 May 2010 on
the energy performance of buildings (recast), referred to as “recast EPDB”.
For the convenience of Standards users CEN/TC 156, together with responsible Working Group
Conveners, have prepared a simple Table below relating, where appropriate, the relationship between
the ‘EPBD’ and ‘recast EPBD’ standard numbers prepared by Technical Committee CEN/TC 156
“Ventilation for buildings”.
