Thermal Bridges in Building Construction—3D Structure Between Two Floors

Model ID: 12573


This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The lowest temperatures on internal surfaces and the heat fluxes through each surface is compared with published data.

This example corresponds to the case 3 described in the European standard EN ISO 10211:2007 for thermal bridges in building constructions.

COMSOL Multiphysics passes successfully all the test cases described by the standard and is hence classified as a three-dimensional steady-state high precision method.

This model was built using the following:
