CORELATION BETWEEN THE THERMAL COUPLING COEFFICIENT AND THE THERMAL PERFORMANCE OF A BUILDING.

Similar to the mechanical behavior of the resistance structure of a building which is completely characterized by the stiffness matrix of the structure, the thermal performance of a building is fully characterized by the thermal coupling coefficients matrix of the space functions in a building and air exchanges matrix between those spaces. Determination of thermal coupling matrix is made in accordance with EN ISO 10211:2007 standard, based on spatial temperature field in thermal stationary regime, inferred for a spatial mesh that includes the building and the ground on which the building is placed. The vertical planes that are sectioning the terrain around the building are considered at a distance of 2.5 x width of the building on all sides, and in the soil to a depth of 7 m. The paper will present a method for the calculation of the thermal performance of buildings that uses the above mentioned matrixes. [ABSTRACT FROM AUTHOR]
