Energy performance of buildings - External climatic conditions - Part 1: Conversion of climatic data for energy calculations (ISO 52010-1:2017)

ISO 52010-1:2017 specifies a calculation procedure for the conversion of climatic data for energy calculations.
The main element in ISO 52010-1:2017 is the calculation of solar irradiance on a surface with arbitrary orientation and tilt. A simple method for conversion of solar irradiance to illuminance is also provided.
The solar irradiance and illuminance on an arbitrary surface are applicable as input for energy and daylighting calculations, for building elements (such as roofs, facades and windows) and for components of technical building systems (such as thermal solar collectors, PV panels).
Other parameters of climatic data needed to assess the thermal and moisture performance of buildings, building elements or technical building systems [like wind, temperature, moisture and long-wave (thermal) radiation] are to be obtained according to the procedures in ISO 15927‑4. These data are listed in ISO 52010-1:2017 as input and passed on as output without any conversion.
NOTE 1    The reason for passing these data via ISO 52010-1:2017 is to have one single and consistent source for all EPB standards and to enable any conversion or other treatment if needed for specific application.
NOTE 2    Table 1 in the Introduction shows the relative position of ISO 52010-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

Energieeffizienz von Gebäuden — Äußere Umweltbedingungen — Teil 1: Umrechnung von Wetterdaten für Energieberechnungen (ISO 52010-1:2017)

Dieses Dokument legt ein Berechnungsverfahren zur Umrechnung von Klimadaten als Eingangsgrößen für Energieberechnungen fest.
Das Hauptelement des Dokuments besteht in der Berechnung der solaren Bestrahlungsstärke auf eine Oberfläche mit beliebiger Ausrichtung und Neigung. Ein einfaches Verfahren für die Umrechnung der solaren Bestrahlungsstärke in Beleuchtungsstärke wird ebenfalls angegeben.
Die solare Bestrahlungsstärke und die Beleuchtungsstärke auf einer beliebigen Oberfläche dienen als Eingabedaten für Energie  und Tageslichtberechnungen, für Bauteile (wie Dächer, Fassaden und Fenster) und für Komponenten der technischen Gebäudeausrüstung (wie Sonnenkollektoren, Photovoltaik-Paneele).
Weitere Klimadaten-Parameter, die für die Bewertung der wärme  und feuchteschutztechnischen Effizienz von Gebäuden, Bauteilen oder Anlagen der technischen Gebäudeausrüstung erforderlich sind [wie Wind, Temperatur, Feuchte und langwellige (Wärme )Strahlung] sind entsprechend der Verfahren in ISO 15927 4 zu erhalten. Diese Daten sind in diesem Dokument als Eingabedaten aufgeführt und werden ohne Umwandlung als Ausgabedaten weitergegeben.
ANMERKUNG 1   Der Grund für die Weitergabe dieser Daten über dieses Dokument besteht darin, über eine einzige und konsistente Quelle für alle EPB-Normen zu verfügen und eine mögliche Umrechnung oder sonstige Behandlung zu ermöglichen, sofern das für eine spezifische Anwendung notwendig ist.
ANMERKUNG 2   Tabelle 1 in der Einleitung zeigt die relative Position dieses Dokuments innerhalb des EPB-Normenpakets im Kontext der in ISO 52000 1 dargelegten modularen Struktur.

Performance énergétique des bâtiments - Conditions climatiques extérieures - Partie 1: Conversion des données climatiques pour les calculs énergétiques (ISO 52010-1:2017)

L'ISO 52010-1:2017 spécifie une procédure de calcul pour la conversion des données climatiques pour les calculs énergétiques.
Le principal élément de l'ISO 52010-1:2017 est le calcul de l'irradiance solaire sur une surface avec une orientation et une inclinaison arbitraires. Une méthode simple de conversion de l'irradiance solaire en éclairement est également fournie.
L'irradiance solaire et l'éclairement sur une surface arbitraire sont applicables comme données d'entrée pour les calculs de l'énergie et de l'éclairage naturel, pour les éléments de bâtiments (comme les toits, les façades et les fenêtres) et pour les composants des systèmes techniques du bâtiment (comme les capteurs solaires thermiques ou les panneaux photovoltaïques).
Les autres paramètres des données climatiques qui sont nécessaires pour évaluer la performance thermique et la performance en matière d'humidité des bâtiments, des éléments de bâtiments ou des systèmes techniques du bâtiment [comme le vent, la température, l'humidité et le rayonnement (thermique) de grandes longueurs d'onde] doivent être obtenus selon les procédures indiquées dans l'ISO 15927‑4. Ces données sont répertoriées dans l'ISO 52010-1:2017 en tant que données d'entrée et elles deviennent des données de sortie sans aucune conversion.
NOTE 1    Ces données ont été incluses dans l'ISO 52010-1:2017 dans le but de disposer d'une source unique et cohérente pour toutes les normes PEB et de permettre de réaliser une conversion ou tout autre traitement si cela est nécessaire pour une application spécifique.
NOTE 2    Le Tableau 1 dans l'Introduction montre la position relative de l'ISO 52010-1:2017dans l'ensemble de normes PEB dans le contexte de la structure modulaire établie par l'ISO 52000‑1.
