Abstract |
This study examines the ventilation performance of single-sided windows using Computational Fluid Dynamics (CFD). In South Korea, where individuals spend approximately 86% of their time indoors, ensuring good indoor air quality through effective natural ventilation is crucial, especially as increasing energy efficiency standards lead to higher building airtightness. The research analyzes how the shape and angle of single-sided windows affect natural ventilation rates. Simulations conducted with Ansys Fluent evaluated different window types and wind incidence angles. The results indicate that wind direction and the window's opening angle significantly impact ventilation efficiency, with a 90° angle providing optimal airflow distribution within a room. These findings offer insights into designing window systems for enhanced natural ventilation, serving as an eco-friendly alternative to mechanical ventilation systems. The study's implications are particularly relevant for urban residential and commercial buildings, where single-sided windows are common due to spatial constraints. |
