Energy performance of buildings - Ventilation for buildings - Part 5-1: Calculation methods for energy requirements of ventilation and air conditioning systems (Modules M5-6, M5-8, M6-5, M6-8, M7-5, M7-8) - Method 1: Distribution and generation

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. See also Clause 2 and Tables A.1 and B.1.

Energetische Bewertung von Gebäuden - Lüftung von Gebäuden - Teil 5-1: Berechnungsmethoden für den Energiebedarf von Lüftungs- und Klimaanlagen (Module M5-6, M5-8, M6-5, M6-8, M7-5, M7-8) - Methode 1: Verteilung und Erzeugung

Diese Europäische Norm gilt für die Berechnung der Energieeffizienz von mechanischen Lüftungs- und Klima¬anlagen, einschließlich Be- und Entfeuchtung. Sie berücksichtigt die Teile zur Erzeugung (zentrales raum¬lufttechnisches Gerät) und zur Verteilung (Luftleitungssystem). Sie enthält eine vereinfachte Berech-nung der adiabatischen Kühlungssysteme. Sie behandelt nicht den Teil zur Übergabe (Berechnung der erforderlichen Luftvolumenströme und/oder Zuluftbedingungen), der durch EN 16798 7 abgedeckt ist. Sie umfasst nicht die Berechnung der Wärme-/Kälteerzeugung. Dieses Verfahren konzentriert sich auf große, individuelle geplante Lüftungs- und Klimaanlagen, wie sie gewöhnlich in Nichtwohngebäuden verwendet werden, auch wenn die Anwendung nicht in Hinsicht auf die Art des Gebäudes oder der Raumnutzung eingeschränkt ist.
Ein Berechnungsverfahren für Lüftungsanlagen mit integrierter Wärme-/Kälteerzeugung, einschließlich der Brauchwarmwasserbereitung, unter Anwendung eines monatlichen oder saisonalen Berechnungsintervalls oder eines Bin Verfahrens ist in einer separaten Norm, EN 16798 5 2, enthalten. Dieses Verfahren umfasst weder die Be- noch die Entfeuchtung oder die adiabatische Kühlung.
Tabelle 1 zeigt die relative Position dieser Norm innerhalb des EPB Normenpakets im Kontext der in EN ISO 52000 1 dargestellten modularen Struktur.
ANMERKUNG 1   In CEN ISO/TR 52000-2 ist die gleiche Tabelle zu finden, die für jedes Modul die Nummern der relevanten EPB-Normen und der zugehörigen Technischen Berichte enthält, die bereits veröffentlicht wurden oder sich in Vorbereitung befinden.
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.

Performance énergétique des bâtiments - Ventilation des bâtiments - Partie 5-1: Méthodes de calcul des besoins énergétiques des systèmes de ventilation et de conditionnement d'air (Modules M5‐6, M5‐8, M6‐5, M6‐8, M7‐5, M7‐8) - Méthode 1: Distribution et génération

La présente Norme européenne traite du calcul de la performance énergétique des systèmes de ventilation et de conditionnement d'air mécaniques, y compris l'humidification et la déshumidification. Elle tient compte des aspects relatifs à la génération (caisson de traitement d'air) et à la distribution (système de conduit). Elle inclut un calcul simplifié des systèmes de refroidissement adiabatique. 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 l’EN 16798 7. Elle n’inclut pas le calcul de la génération de chaleur/froid. Cette méthode se focalise sur les systèmes de ventilation et de conditionnement d'air de grande taille, sur mesure, généralement utilisés dans les bâtiments commerciaux, 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 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, est fournie dans une norme séparée, EN 16798-5-2. Cette méthode n'inclut pas l'humidification et la déshumidification ou le refroidissement adiabatique.
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, le Tableau A.1 et le Tableau B.1.
