Energy performance of buildings - Overarching EPB assessment - Part 1: General framework and procedures (ISO 52000-1:2017)

ISO 52000-1:2017 establishes a systematic, comprehensive and modular structure for assessing the energy performance of new and existing buildings (EPB) in a holistic way.
It is applicable to the assessment of overall energy use of a building, by measurement or calculation, and the calculation of energy performance in terms of primary energy or other energy-related metrics. It takes into account the specific possibilities and limitations for the different applications, such as building design, new buildings 'as built', and existing buildings in the use phase as well as renovation.
NOTE Table 1 in the Introduction shows the relative position of ISO 52000-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1:2017.

Energieeffizienz von Gebäuden - Festlegungen zur Bewertung der Energieeffizienz von Gebäuden - Teil 1: Allgemeiner Rahmen und Verfahren (ISO 52000-1:2017)

Diese Internationale Norm stellt eine systematische, umfassende und modulare Struktur zur integrierten ener-getischen Bewertung von Gebäuden zur Verfügung, um die Einheitlichkeit aller EPB-Normen, die zur Berech-nung der Energieeffizienz von Gebäuden erforderlich sind, sicherzustellen.
Diese Norm stellt einen Rahmen für die Bewertung der Gesamtenergieeffizienz von Gebäuden dar und umfasst unter anderem:
a)   allgemeine Begriffe und Symbole;
b)   Gebäude- und Bilanzgrenzen;
c)   Partitionierung von Gebäuden in Bereichskategorien;
d)   eine Methodologie zur Berechnung der Energieeffizienz von Gebäuden (eine Reihe von umfassenden Gleichungen zur Berechnung der Energie, die am Gebäudestandort und in der Nähe des Gebäudes verbraucht, geliefert, erzeugt und/oder exportiert wird);
e)   eine Reihe von umfassenden Gleichungen und Eingabe-/Ausgabe-Beziehungen, die die verschiedenen Elemente, die für die Bewertung der Gesamtenergieeffizienz von Gebäuden maßgebend sind und in unterschiedlichen EPB-Normen behandelt werden, miteinander verbinden;
f)   allgemeine Anforderungen an EPB-Normen, die Teilberechnungen behandeln;
g)   Regeln für die Zusammenfassung unterschiedlicher Bereiche in Zonen;
h)   Leistungsindikatoren;
i)   eine Methodologie zur Bewertung der Energieverbrauchskennwerte.
Die Verfahren berücksichtigen die für die verschiedenen Anwendungen, wie z. B. den Gebäudeentwurf, das „fertige“ neue Gebäude, bestehende Gebäude in der Nutzungsphase und Renovierungen geltenden speziel¬len Möglichkeiten und Begrenzungen.

Performance énergétique des bâtiments - Évaluation cadre PEB - Partie 1: Cadre général et modes opératoires (ISO 52000-1:2017)

L'ISO 52000-1:2017 établit une structure systématique, complète et modulaire pour évaluer la performance énergétique des bâtiments neufs et existants (PEB) de manière globale.
Il est applicable à l'évaluation de la consommation globale d'énergie d'un bâtiment, par mesure ou par calcul, et au calcul de la performance énergétique en termes d'énergie primaire ou d'autres indicateurs en lien avec l'énergie. Il prend en compte les possibilités et les limites spécifiques des différentes applications, telles que la conception du bâtiment, les bâtiments neufs «conformes à l'exécution» et les bâtiments existants en phase d'utilisation, ainsi que ceux faisant l'objet d'une rénovation.
NOTE Le Tableau 1 de l'Introduction indique la position relative de l'ISO 52000-1:2017 dans la série de normes PEB dans le contexte de la structure modulaire définie dans le présent document.

Energijske lastnosti stavb - Krovni standard za ocenjevanje energijskih lastnosti stavb - 1. del: Splošni okvir in postopki (ISO 52000-1:2017)

Ta standard nudi sistematično, obsežno in modularno splošno strukturo za integrirano energetsko učinkovitost stavb z namenom zagotavljanja doslednosti med vsemi standardi CEN, ki so potrebni za izračun energetske učinkovitosti stavb v skladu s standardom EPBD (2010/31/EU).
Ta standard obravnava okvir splošne energetske učinkovitosti stavbe, ki med drugim zajema:
a) splošne izraze, definicije in simbole;
b) omejitve stavbe in sistema;
c) delitev stavbe;
d) metodologijo za izračun energetske učinkovitosti stavbe (komplet splošnih formul za porabljeno, dobavljeno, proizvedeno in/ali izvoženo energijo na gradbišču in v bližini);
e) komplet splošnih formul za vhodno-izhodna razmerja, ki povezuje različne elemente, ki so pomembni za oceno splošne energetske učinkovitosti stavb, ki so obravnavane v ločenih standardih;
f) splošne zahteve za standarde, ki se nanašajo na delne izračune;
g) splošna pravila za določitev alternativnih poti za izračun glede na obseg in zahteve izračuna;
h) pravila za kombinacijo različnih delitev:
i) kazalniki učinkovitosti;
j) metodologija za oceno izmerjene energetske učinkovitosti.

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.
