Description	A computational approach is applied for the determination of effective thermal conductivity of hollow brick blocks. At first, the thermal properties of the brick body are measured by an impulse technique and the apparent thermal conductivity of the air cavities is calculated using a simplified approach. Then, a finite element approach is applied for the calculation of steady-state temperature fields and heat fluxes in the hollow bricks for characteristic boundary conditions, using the data for thermal conductivity of the brick body and the air as input parameters. The effective thermal conductivity of hollow brick block is then identified using the Fourier's law. Finally, the computational results are verified using a steady-state experiment simulating heat transport in the brick block in difference temperature conditions.
