The Effect of Window Placement on Natural Ventilation Capability in a Jakarta High-Rise Building Unit

The purpose of this study was to investigate the natural ventilation potential in an apartment unit a high-rise building. A corner two-bedroom selected for study, where single-sided and cross occurred unit. This employed CFD simulation model indoor airflow West Jakarta. units were modelled simulated using with RANS k-ε turbulence model. results validated readings from field measurements that had been conducted. Based on results, window position influences airflow. In case ventilation, windward opening is more beneficial, while leeward creates Therefore, it recommended characteristic design be considered early stage not only improve air quality but also maintain privacy safety measures.
