THERMAL PROPERTIES

Enhancing the thermal performance of building envelopes is crucial for improving energy efficiency and indoor comfort. This study examines how different material combinations influence heat transfer through composite walls. To achieve this, we conducted both theoretical calculations and ANSYS simulations, analyzing various wall configurations. The study focused on steady-state heat transfer, considering conduction and convection while neglecting the first convective resistance. We tested multiple material setups, including Dense and Medium Dense Hollow Concrete Blocks, Fiber Glass Insulation, Rock Wool, Polystyrene Foam, Air Cavity, Agba Wood, and Mahogany. The analysis was carried out under controlled conditions, with an outer surface temperature of 35°C, an inner fluid temperature of 25°C, and a convective heat transfer coefficient of 25 W/m²·K at the inner surface. Our findings offer valuable insights into selecting materials that can optimize building envelopes, reduce heat transfer, and enhance indoor thermal comfort. This research contributes to the development of more energy-efficient and sustainable building designs
