Thermal performance of buildings - Heat transfer via the ground - Calculation methods

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.

Thermal performance of buildings - Heat transfer via the ground - Calculation methods

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.

Thermal performance of buildings. Heat transfer via the ground. Calculation methods.

Le présent document spécifie des méthodes de calcul de 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 comprend le calcul de la partie du transfert thermique correspondant au régime stationnaire (flux de chaleur moyen annuel) et de la partie du transfert thermique résultant des variations périodiques annuelles de la température (variations saisonnières sur une base mensuelle de flux de chaleur autour de la moyenne annuelle).
