Abstract
This research paper delves into the optimization of window size and placement for window wind-catchers (WWCs) in office buildings using a Computational Fluid Dynamics (CFD) simulation approach. Recognizing the critical role of natural ventilation in sustainable building design, this study evaluates various window configurations to maximize airflow rates and indoor air quality (IAQ). CFD simulations were conducted on an office building model with varying window sizes and placements. The findings demonstrate that increasing the window size enhances the airflow rate, with larger windows achieving up to a 40 % increase compared to smaller configurations. Additionally, optimizing window placement reduced stagnation zones by approximately 30 %, improving airflow distribution. These results provide architects, engineers, and building designers with valuable insights into the most effective strategies for optimizing WWCs in office buildings to achieve superior indoor environmental conditions.
