EN ISO 15927-6:2007

Hygrothermal performance of buildings - Calculation and presentation of climatic data - Part 6: Accumulated temperature differences (degree-days) (ISO 15927-6:2007)

ISO 15927-6:2007 specifies the definition, method of computation and method of presentation of data on accumulated temperature differences, used for assessing the energy used for space heating in buildings. These are normally expressed in degree‑hours or degree-days, and such data are often referred to simply as "heating degree-hours" or "heating degree-days".
ISO 15927-6:2007 includes approximate methods for calculating accumulated temperature differences based on hourly or daily mean temperatures and for estimating monthly values to any base temperature, for use when data computed directly from meteorological air temperature records are not available.
In some countries, a threshold temperature different from the base temperature is used. ISO 15927-6:2007 does not cover this.

Wärme- und feuchteschutztechnisches Verhalten von Gebäuden - Berechnung und Darstellung von Klimadaten - Teil 6: Akkumulierte Temperaturdifferenzen (Gradtage) (ISO 15927-6:2007)

Dieser Teil der ISO 15927 legt die Definitionen, Berechnungsverfahren und Darstellungsverfahren von Daten zu akkumulierten Temperaturdifferenzen fest, die zum Abschätzen der für die Raumheizung in Gebäuden verbrauchten Energie verwendet werden. Die Temperaturdifferenzen werden üblicherweise in Gradstunden oder Gradtagen ausgedrückt, und derartige Daten werden oft einfach als „Heizgradstunden“ oder „Heizgrad¬tage“ bezeichnet.
Dieser Teil der ISO 15927 enthält Näherungsverfahren zur Berechnung der akkumulierten Temperatur¬differenzen auf Grundlage mittlerer stündlicher oder täglicher Temperaturen und zum Abschätzen der Monatswerte gegenüber einer Grundtemperatur, die dann angewendet werden, wenn keine aus den meteorologischen Aufzeichnungen der Lufttemperatur direkt berechneten Daten zur Verfügung stehen.
In einigen Ländern wird eine von der Grundtemperatur abweichende Schwellenwerttemperatur verwendet. Dieser Teil der ISO 15927 berücksichtigt dies nicht.

Performance hygrothermique des bâtiments - Calcul et présentation des données climatiques - Partie 6: Écarts de température cumulés (degrés-jour) (ISO 15927-6:2007)

L'ISO 15927-6:2007 spécifie la définition, la méthode de calcul et la méthode de présentation des données d'écarts de température cumulés, utilisées pour évaluer la dépense énergétique de chauffage dans les bâtiments. Les résultats sont généralement exprimés en degrés-heure ou en degrés-jour et ces données sont souvent simplement appelées «degrés-heure de chauffage» ou «degrés-jour de chauffage».
L'ISO 15927-6:2007 indique des méthodes approchées pour le calcul des écarts de température cumulés sur la base de températures moyennes horaires ou journalières et pour l'estimation de valeurs mensuelles par rapport à une température de base donnée, lorsque aucune donnée calculée directement à partir des enregistrements météorologiques de température de l'air n'est disponible.
Dans certains pays, la température limite utilisée est différente de la température de base. Ce cas n'est pas couvert par la présente partie de l'ISO 15927-6:2007.
