Energy performance of buildings - Ventilation for buildings - Part 5-2: Calculation methods for energy requirements of ventilation systems (Modules M5-6, M5-8, M6-5, M6-8, M7-5, M7-8) - Method 2: Distribution and generation

This European Standard covers energy performance calculation of mechanical ventilation systems with integrated heating/cooling generation, including domestic hot water production, using a monthly or seasonal calculation interval or a bin method. 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 the M5-5 standard. It does not include humidification and dehumidification. This method is focussed on small, packaged ventilation systems, typically used in residential buildings, although the application is not restricted on the basis of building or space use type.
A calculation method for mechanical ventilation and air conditioning systems, including humidification and dehumidification, using an hourly calculation interval or a bin method, is provided in a separate standard, EN 16798 5 1.
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. See also Clause 2 and Tables A.1 and B.1.

Energetische Bewertung von Gebäuden - Lüftung von Gebäuden - Teil 5-2: Berechnungsmethoden für den Energiebedarf von Lüftungssystemen (Module M5-6.2, M5-8.2) - Methode 2: Verteilung und Erzeugung

Diese Europäische Norm behandelt die Berechnung der Energieeffizienz mechanischer Lüftungsanlagen mit integrierter Heizung/Kühlung einschließlich der Brauchwarmwasserbereitung unter Verwendung eines monatlichen oder jahreszeitlichen Berechnungsintervalls oder eines Bin-Verfahrens. Sie berücksichtigt die Teile zur Erzeugung (zentrales raumlufttechnisches Gerät) und zur Verteilung (Luftleitungssystem). Sie behandelt nicht den Teil zur Emission (Berechnung der erforderlichen Luftvolumenströme und/oder Zuluftbedingungen), der durch die Norm M5 5 abgedeckt ist. Sie umfasst weder die Be  noch die Entfeuchtung. Dieses Verfahren konzentriert sich auf kleine, gebündelte Lüftungsanlagen, wie sie gewöhnlich in Wohngebäuden verwendet werden, auch wenn die Anwendung nicht in Hinsicht auf die Art des Gebäudes oder der Raumnutzung eingeschränkt ist.
Ein Berechnungsverfahren für mechanische Lüftungs- und Klimaanlagen, einschließlich Be- und Entfeuchtung, unter Anwendung eines stündlichen Berechnungszeitschritts oder eines Bin-Verfahrens ist in einer separaten Norm, EN 16798 5 1, enthalten.
Tabelle 1 zeigt die relative Position dieser Norm innerhalb des EPB-Normenpakets im Kontext der in EN ISO 52000 1 dargelegten modularen Struktur
ANMERKUNG 1   In CEN ISO/TR 52000 2 ist die gleiche Tabelle zu finden und sie enthält für jedes Modul die Nummern der relevanten EPB-Normen und der zugehörigen technischen Berichte, die veröffentlicht wurden oder in Vorbereitung sind.
ANMERKUNG 2   Die Module stellen EPB-Normen dar, auch wenn eine EPB-Norm mehr als ein Modul abdecken kann und ein Modul von mehr als einer EPB-Norm abgedeckt sein kann, wie es sich zum Beispiel bei einem vereinfachten und einem detaillierteren Verfahren verhält. Siehe auch Abschnitt 2 und Tabellen A.1 und B.1.

Performance énergétique des bâtiments - Ventilation des bâtiments - Partie 5-2 : Méthodes de calcul pour les besoins énergétiques des systèmes de ventilation (Modules M5-6, M5-8, M6-5, M6-8, M7-5, M7-8) - Méthode 2 : Distribution et génération

La présente Norme européenne traite du calcul de la performance énergétique des systèmes de ventilation mécanique avec génération de chaleur/froid intégrée, y compris la production d'eau chaude sanitaire, utilisant un intervalle de calcul mensuel ou saisonnier ou une méthode bin. Elle tient compte des aspects relatifs à la génération (caisson de traitement d'air) et à la distribution (système de conduit). Elle ne traite pas des aspects relatifs aux émissions (calcul des débits volumiques requis et/ou conditions pour l'air fourni), qui sont traités dans la norme M5-5. Elle n'inclut pas l'humidification et la déshumidification. Cette méthode se focalise sur les systèmes de ventilation de petite taille, en kit, généralement utilisés dans les bâtiments résidentiels, bien que son application ne soit pas restreinte en fonction du type de bâtiment ou d'utilisation de l'espace.
Une méthode de calcul pour les systèmes de ventilation mécanique et de conditionnement d'air, y compris l'humidification et la déshumidification, en appliquant un intervalle de calcul horaire ou une méthode bin, est fournie dans une autre norme, l'EN 16798-5-1.
Le Tableau 1 indique la position relative de la présente norme dans l’ensemble de normes PEB dans le cadre de la structure modulaire donnée dans l’EN ISO 52000-1.
NOTE 1   Le même tableau figure dans le CEN ISO/TR 52000-2 avec, pour chaque module, le numéro des normes PEB correspondantes et les rapports techniques associés qui sont publiés ou en cours d'élaboration.
NOTE 2   Les modules représentent des normes PEB, bien qu'une norme PEB puisse couvrir plus d'un module et qu'un module puisse être couvert par plusieurs normes PEB, par exemple une méthode simplifiée et détaillée respectivement. Voir également l'Article 2 et les Tableaux A.1 et B.1.
