In this article, the influence of the use of three different bricks on the building heat performance is compared for use on wall surfaces as a building construction element. At the beginning of the analysis, the thermal analysis of the building was carried out for both bricks with different heat transfer coefficients. Within the scope of the analysis, depending on the building material used, changes in the total fuel cost were observed with the help of the Engineering Equations Solver (EES) program by changing the brick thickness at certain rates in both cases. As a result of these observations and analyzes, the choice of paper reinforced clay bricks instead of standard wall bricks has resulted in a significant reduction in fuel costs. Also, as a result of this work, the use of paper waste reinforced clay bricks instead of normal wall bricks as building materials will contribute to saving energy by reducing both production costs and recovering waste by recycling.
