Thermal performance of buildings -- Heat transfer via the ground -- Calculation methods
This standard gives 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 and suspended floors, at the level of the inside floor surface;
- for basements, at the level of the external ground surface.
It 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; this standard does not apply to shorter periods of time.
