Ventilation for buildings - Calculation methods for energy losses due to ventilation and infiltration in commercial buildings
This European Standard describes the method to calculate the energy impact of ventilation systems (including airing) in buildings to be used for applications such as energy calculations, heat and cooling load calculation.
Its purpose is to define how to calculate the characteristics (temperature, humidity) of the air entering the building, and the corresponding energies required for its treatment and the auxiliaries electrical energy required.
This standard can also be used for air heating and cooling systems when they assure the provision of ventilation, considering that prEN 15243 will provide the required heating or cooling load and the corresponding air flows and/or air temperatures.
Lüftung von Gebäuden - Berechnungsverfahren für den Energieverlust aufgrund der Lüftung und Infiltration in Nichtwohngebäuden
Diese Europäische Norm beschreibt das Verfahren zur Berechnung der energetischen Auswirkungen von Lüftungsanlagen (einschließlich Fensterlüftung) in Gebäuden, das z. B. bei Energieberechnungen und Heiz und Kühllastberechnungen anzuwenden ist.
Der Zweck besteht darin, festzulegen, wie die Kennwerte (Temperatur, Luftfeuchte) der in das Gebäude eintretenden Luft und die entsprechenden für ihre Behandlung erforderlichen Energien und elektrische Hilfsenergie zu berechnen sind.
Diese Norm kann auch auf Lufterhitzer und kühler angewendet werden, wenn sie die Lüftung sicherstellen, wobei zu berücksichtigen ist, dass die geforderte Heiz bzw. Kühllast und die entsprechenden Luft¬volumen¬ströme und/oder Lufttemperaturen in prEN 15243 festgelegt werden.
Ventilation des bâtiments - Méthodes de calcul des pertes d'énergie dues à la ventilation et à l'infiltration dans les bâtiments commerciaux
La présente Norme européenne décrit la méthode de calcul de l’impact énergétique des systèmes de ventilation (y compris l’aération) dans les bâtiments, utilisée pour des applications telles que les calculs d’énergie et le calcul de la charge de chauffage et de refroidissement.
La présente norme vise à définir les méthodes de calcul des caractéristiques (température, humidité) de l’air entrant dans le bâtiment, et les énergies correspondantes requises pour le traitement de cet air et les énergies requises par les auxiliaires électriques.
La présente norme peut également être utilisée pour les systèmes de refroidissement et de chauffage de l’air lorsqu’ils assurent la ventilation, sachant que le prEN 15243 fournira les charges de refroidissement et de chauffage exigées et les températures d’air et/ou les débits d’air correspondants.
