Thermal performance of buildings - Heat transfer via the ground - Calculation methods (ISO 13370:2017)
ISO 13370:2017 provides methods of calculation of heat transfer coefficients and heat flow rates for building elements in thermal contact with the ground, including slab‐on‐ground floors, suspended floors and basements. It applies to building elements, or parts of them, below a horizontal plane in the bounding walls of the building situated
- at the level of the inside floor surface, for slab‐on‐ground floors, suspended floors and unheated basements;
NOTE 1 In some cases, external dimension systems define the boundary at the lower surface of the floor slab.
- at the level of the external ground surface, for heated basements.
ISO 13370:2017 includes calculation of the steady‐state part of the heat transfer (the annual average rate of heat flow) and the part due to annual periodic variations in temperature (the seasonal variations of the heat flow rate about the annual average). These seasonal variations are obtained on a monthly basis and, except for the application to dynamic simulation programmes in Annex D, ISO 13370:2017 does not apply to shorter periods of time.
NOTE 2 Table 1 in the Introduction shows the relative position of ISO 13370:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.
Wärmetechnisches Verhalten von Gebäuden - Wärmeübertragung über das Erdreich - Berechnungsverfahren (ISO 13370:2017)
Dieses Dokument gibt Verfahren zur Berechnung von Wärmeübertragungskoeffizienten und der Wärmeübertragung durch Bauteile an, die sich in wärmetechnischem Kontakt mit dem Erdreich befinden, einschließlich Bodenplatten auf Erdreich, aufgeständerter Bodenplatten und Kellergeschossen. Es gilt für Bauwerksteile oder Teile dieser, die unterhalb einer waagrechten Ebene der angrenzenden Wände des Gebäudes liegen:
für Bodenplatten auf Erdreich, aufgeständerte Bodenplatten und unbeheizte Kellergeschosse: in Höhe der raumseitigen Bodenplattenoberfläche;
ANMERKUNG In einigen Fällen wird die Grenze der Oberfläche der Bodenplatte von externen Maßsystemen niedriger bestimmt.
für beheizte Kellergeschosse: in Höhe der Oberfläche des umgebenden Erdreichs.
Dieses Dokument schließt die Berechnung der stationären Komponente des Wärmestroms über das Erdreich (Jahresmittel des Wärmestromes über das Erdreich) und der Komponente infolge von jährlichen periodischen Temperaturschwankungen (auf das Jahresmittel bezogene jahreszeitliche Schwankungen des Wärmestromes) ein. Diese jahreszeitlichen Schwankungen werden monatsweise ermittelt, und dieses Dokument gilt nicht für kürzere Zeitabschnitte; ausgenommen ist die Anwendung auf die dynamischen Simulationsprogramme nach Anhang D.
Tabelle 1 zeigt die relative Position dieses Dokuments innerhalb des EPB-Normenpakets im Kontext der in ISO 52000-1 dargelegten modularen Struktur.
ANMERKUNG 1 In ISO/TR 52000-2 befindet sich die gleiche Tabelle, in der für jedes Modul die Nummern der relevanten EPB-Normen und die begleitenden Technischen Berichte aufgeführt sind, die veröffentlicht oder in Bearbeitung sind.
ANMERKUNG 2 Die Module stehen grundsätzlich für EPB-Normen, auch wenn eine EPB-Norm mehr als ein Modul abdecken kann bzw. ein Modul von mehr als einer EPB-Norm abgedeckt werden kann, etwa im Falle eines vereinfachten und eines ausführlichen Verfahrens.

Performance thermique des bâtiments - Transfert de chaleur par le sol - Méthodes de calcul (ISO 13370:2017)
L'ISO 13370:2017 décrit des méthodes de calcul des coefficients de transfert thermique et des flux thermiques des parois de bâtiments en contact avec le sol, comprenant les planchers sur terre-plein, les planchers sur vide sanitaire et les sous-sols. Il s'applique aux parois, ou portions de parois, se trouvant en dessous d'un plan horizontal dans l'enveloppe extérieure du bâtiment, qui est situé:
- au niveau de la surface du plancher intérieur, dans le cas de planchers sur terre-plein, de planchers sur vide sanitaire et de sous-sols non chauffés;
NOTE Pour certains cas, les dimensions extérieures définissent la limite à la surface inférieure de la dalle de plancher.
- au niveau de la surface du sol extérieur, dans le cas de sous-sols chauffés.
L'ISO 13370:2017 comprend le calcul de la partie du transfert thermique correspondant au régime stationnaire (flux thermique moyen annuel), ainsi que de la partie du transfert thermique résultant des variations périodiques annuelles de la température (variations saisonnières du flux thermique autour de la moyenne annuelle). Ces variations saisonnières sont déterminées sur une base mensuelle. L'ISO 13370:2017 n'est pas applicable à des périodes de temps plus courtes, sauf pour l'application aux programmes de simulation dynamique de l'Annexe D.
NOTE Le Tableau 1 de l'Introduction indique la position relative de l'ISO 13370:2017 dans la série de normes PEB dans le contexte de la structure modulaire définie dans l'ISO 52000‑1.
Toplotne značilnosti stavb - Prenos toplote skozi zemljo - Računske metode (ISO 13370:2017)
Ta dokument določa metode za izračun koeficientov prenosa toplote in stopnje toplotnega toka za stavbne elemente v toplotnem stiku s tlemi, vključno s podi iz plošč, spuščenimi podi in kletmi. Uporablja se za stavbne elemente (ali njihove dele) pod vodoravno ravnino v veznih stenah stavbe:
– na ravni notranje talne površine (za pode iz plošč, spuščene pode in neogrevane kleti);
V nekaterih primerih sistemi zunanjih dimenzij določajo mejo na spodnji površini talne plošče.
– na ravni zunanje talne površine (za ogrevane kleti).
Ta dokument vključuje izračun ustaljenega dela prenosa toplote (povprečna letna stopnja toplotnega toka) in dela, ki je posledica rednih letnih sprememb temperature (sezonske spremembe stopnje toplotnega toka v bližini letnega povprečja). Podatki o teh sezonskih spremembah se pridobijo vsak mesec in ta dokument se ne uporablja za krajša časovna obdobja, razen za namene uporabe za programe dinamične simulacije iz dodatka D.
Preglednica 1 v uvodu prikazuje relativno mesto tega dokumenta znotraj skupine standardov EPB v kontekstu modularne strukture, kot je opredeljeno v standardu ISO 52000-1.

European foreword
This document (EN ISO 13370:2017) 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 13370:2007.
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.
