Abstract:
The rise in energy consumption in recent years has not only heightened concerns about the depletion of fossil resources but has also led to severe and threatening environmental changes worldwide. Buildings play a significant role as major energy consumers, with residential buildings being particularly important due to their continuous use throughout the day and night. This study aims to investigate the impact of thermal insulation applied to the external walls of residential buildings on cooling and heating energy consumption. Additionally, it seeks to determine the differences between various placements of thermal insulation and identify their optimal thicknesses. Given that testing and comparing different scenarios on an accurate scale would require substantial time and resources, this research employs a simulation-based approach. Modeling and simulations were conducted using Rhino and EnergyPlus software. For this purpose, three common land plot sizes from the city of Qom were selected, and each was simulated in two configurations (north-facing and south-facing) and seven geographical orientations. The final outputs include (1) the percentage contribution of each external wall in reducing energy consumption, (2) the priority ranking of walls for insulation, (3) the effect of the last floor ceiling and pilot roof insulation, and (4) the recommended optimal thickness for thermal insulation. By analyzing the energy load reductions achieved, the study determines the most effective conditions and optimal thicknesses for thermal insulation in the external walls of buildings
