Thermal performance of buildings - Transmission and ventilation heat transfer coefficients - Calculation method (ISO 13789:2017)
ISO 13789:2017 specifies a method and provides conventions for the calculation of the steady‐state transmission and ventilation heat transfer coefficients of whole buildings and parts of buildings. It is applicable both to heat loss (internal temperature higher than external temperature) and to heat gain (internal temperature lower than external temperature). For the purpose of ISO 13789:2017, the heated or cooled space is assumed to be at uniform temperature.
Annex C provides a steady‐state method to calculate the temperature in unconditioned spaces adjacent to conditioned spaces.
NOTE Table 1 in the Introduction shows the relative position of ISO 13789:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.
Wärmetechnisches Verhalten von Gebäuden - Transmissions- und Lüftungswärmetransferkoeffizient - Berechnungsverfahren (ISO 13789:2017)
Dieses Dokument legt ein Verfahren zur Berechnung des stationären Transmissions- und des stationären Lüftungswärmetransferkoeffizienten von vollständigen Gebäuden und Gebäudeteilen fest und liefert die entsprechenden Vereinbarungen. Es gilt sowohl für den Wärmeverlust (Innentemperatur höher als Außentemperatur) als auch für den Wärmegewinn (Innentemperatur geringer als Außentemperatur). Für die Anwendung dieses Dokuments wird für den beheizten oder gekühlten Raum eine einheitliche Temperatur angenommen.
Anhang C legt ein stationäres Verfahren zur Berechnung der Temperatur in nicht konditionierten Räumen, die an konditionierte Räume angrenzen, fest.
ANMERKUNG Tabelle 1 in der Einleitung zeigt die relative Einordnung dieses Dokuments innerhalb des EPB-Normenpakets im Kontext der in ISO 52000-1 dargelegten modularen Struktur.
Performance thermique des bâtiments - Coefficients de transfert de chaleur par transmission et par renouvellement d'air - Méthode de calcul (ISO 13789:2017)
L'ISO 13789:2017 établit une méthode et des conventions pour le calcul des coefficients de transfert thermique par transmission et par renouvellement d'air, en régime stationnaire, pour des bâtiments complets ou des parties de bâtiments. Il s'applique aux déperditions thermiques (température intérieure supérieure à la température extérieure) comme aux gains thermiques (température intérieure inférieure à la température extérieure). Pour les besoins de l'ISO 13789:2017, la température de l'espace chauffé ou refroidi est supposée uniforme.
L'Annexe C donne une méthode de calcul de la température, en régime stationnaire, dans des espaces non conditionnés adjacents à des espaces conditionnés.

Toplotne značilnosti stavb - Toplotni koeficienti pri prenosu toplote in prezračevanju - Računska metoda (ISO 13789:2017)
Ta dokument določa metodo in vključuje dogovore za izračun toplotnih koeficientov pri ustaljenem prenosu toplote in prezračevanju v celotnih stavbah ter njihovih delih. Uporablja se tako za toplotne izgube (notranja temperatura je višja od zunanje) kot toplotne dobičke (notranja temperatura je nižja od zunanje). Za namene tega dokumenta se predvideva, da je temperatura ogrevanega ali hlajenega prostora enaka.
V dodatku C je podana ustaljena metoda za izračun temperature v toplotno nereguliranih prostorih poleg toplotno reguliranih prostorov.

European foreword
This document (EN ISO 13789:2017) has been prepared by Technical Committee ISO/TC 163 "Thermal
performance and energy use in the built environment" in collaboration with Technical Committee
CEN/TC 89 “Thermal performance of buildings and building components” the secretariat of which is
held by SIS.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2018 and conflicting national standards shall
be withdrawn at the latest by January 2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
This document is part of the set of standards and accompanying technical reports on the energy
performance of buildings and has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association (Mandate M/480, see reference [EF3] below).
Directive 2010/31/EU recasting the Directive 2002/91/EC on energy performance of buildings (EPBD,
[EF4]) promotes the improvement of the energy performance of buildings within the European Union,
taking into account all types of energy uses (heating, lighting, cooling, air conditioning, ventilation) and
outdoor climatic and local conditions, as well as indoor climate requirements and cost effectiveness
(Article 1).
The directive requires Member States to adopt measures and tools to achieve the prudent and rational
use of energy resources. In order to achieve those goals, the EPBD requires increasing energy efficiency
and the enhanced use of renewable energies in both new and existing buildings. One tool for this is the
application by Member States of minimum requirements on the energy performance of new buildings
and for existing buildings that are subject to major renovation, as well as for minimum performance
requirements for the building envelope if energy-relevant parts are replaced or retrofitted. Other tools
are energy certification of buildings, inspection of boilers and air-conditioning systems.
The use of European standards increases the accessibility, transparency and objectivity of the energy
performance assessment in the Member States facilitating the comparison of best practices and
supporting the internal market for construction products. The use of EPB standards for calculating
energy performance, as well as for energy performance certification and the inspection of heating
systems and boilers, ventilation and air-conditioning systems will reduce costs compared to developing
different standards at national level.
The first mandate to CEN to develop a set of CEN EPBD standards (M/343, [EF1]), to support the first
edition of the EPBD ([EF2]) resulted in the successful publication of all EPBD related CEN standards in
2007-2008.
Mandate M/480 was issued to review the mandate M/343 as the recast of the EPBD raised the need to
revisit the standards and reformulate and add standards so that they become on the one hand
unambiguous and compatible, and on the other hand a clear and explicit overview of the choices,
boundary conditions and input data that need to be defined at national or regional level. Such national
or regional choices remain necessary, due to differences in climate, culture and building tradition,
policy and legal frameworks. Consequently, the set of CEN EPBD standards published in 2007-2008 had
to be improved and expanded on the basis of the recast of the EPBD.
The EPB standards are flexible enough to allow for necessary national and regional differentiation and
facilitate Member States implementation and the setting of requirements by the Member States.
Further target groups are users of the voluntary common European Union certification scheme for the
energy performance of non-residential buildings (EPBD article 11.9) and any other regional (e.g. pan
European) parties wanting to motivate their assumptions by classifying the building energy
performance for a dedicated building stock.
This document supersedes EN ISO 13789:2007.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
