Influence of Roof Design on Interior Airflow Characteristics

Over the past few years, there has been a growing emphasis on energy conservation and enhancing thermal comfort, which has compelled building designers to enhance their design practices. The purpose of this paper is to address this challenge by creating a comprehensive 3D Computational Fluid Dynamics simulation to analyze the indoor environment, specifically considering the influence of roof height (r). The results obtained from the simulations have revealed the direct impact of roof height on key factors such as velocity vector Fields distribution, static pressure distribution, turbulent kinetic energy, and turbulent viscosity. These findings provide valuable insights into the importance of optimizing roof height to significantly improve the indoor environment. To ensure the accuracy and reliability of these findings, robust correlations have been established based on numerical data. By leveraging this knowledge, designers and architects can make informed decisions and implement effective strategies to enhance energy efficiency and thermal comfort in buildings. Ultimately, this research contributes to the ongoing efforts in achieving sustainable and comfortable indoor environments.
