Thermal performance of buildings - Heat transfer via the ground - Calculation methods (ISO 13370:2007)
ISO 13370:2007 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
for slab-on-ground floors, suspended floors and unheated basements, at the level of the inside floor surface;
for heated basements, at the level of the external ground surface.
ISO 13370:2007 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 13370:2007 does not apply to shorter periods of time.
Wärmetechnisches Verhalten von Gebäuden - Wärmeübertragung über das Erdreich - Berechnungsverfahren (ISO 13370:2007)
Diese Internationale Norm 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. Sie 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 Bodenplatten¬oberfläche;
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.
Die Internationale Norm 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, diese Norm gilt nicht für kürzere Zeitabschnitte; ausgenommen ist die Anwendung auf die dynamischen Simulationspro¬gramme nach Anhang D.
Performance thermique des bâtiments - Transfert de chaleur par le sol - Méthodes de calcul (ISO 13370:2007)
L'ISO 13370:2007 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. Elle 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, et au niveau de la surface du sol extérieur, dans le cas de sous-sols chauffés.
L'ISO 13370:2007 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 13370:2007 n'est pas applicable à des périodes de temps plus courtes, sauf pour l'application aux programmes de simulation dynamique de l'Annexe D.

Foreword
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13370 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 2, Calculation methods.
This second edition cancels and replaces the first edition (ISO 13370:1998), which has been technically
revised.
The following principal changes have been made to the first edition:
⎯ Clause 4 contains a revised text to clarify the intention of the initial part of the former Annex A; the rest of
the former Annex A is now contained in ISO 10211;
⎯ 7.2 no longer contains a table of linear thermal transmittances: it is now recognized, as with other thermal
bridging, that the wall/floor junction often needs to be calculated;
⎯ 9.1 provides an alternative formula for well-insulated floors;
⎯ 9.2 provides clarification for low-emissivity surfaces;
⎯ Annex A contains formulae for cooling applications;
⎯ Annex B has incorporated minor revisions to the text for edge-insulated floors;
⎯ Annex D has been revised;
⎯ Annex F (formerly
