| Abstract: | The purpose of this study is to determine the thermal conductance of concrete hollow bricks, which is necessary for the evaluation of the energy efficiency of a building. The three varieties of hollow concrete bricks that are often used to build walls in Morocco are the subject of this study. A computational model created using the finite volume method is used to evaluate the conjugate heat transfer through concrete hollow bricks. According to the results, the use of hollow brick type Ah3 reduces the heat flux by approximately 86% compared with type Ah1. It is undeniable that hollow bricks type Ah3 with a thermal conductivity of 1 W/m K can improve the thermal characteristics of building walls. |
