  "abstract": "Natural ventilation is crucial for ensuring indoor air quality and improving energy efficiency in multi-story buildings. This study employs CFD (Computational Fluid Dynamics) simulations to investigate the inter-floor interactions of pollutant source floor, opening location (windward/leeward), and ventilated floor combinations on ventilation efficiency and pollutant transmission in multi-story buildings under the SS2 (single-sided ventilation with two openings) ventilation type. Results show that when the pollutant is released on the bottom floor, the peak PFR (purging flow rate) on the leeward side occurs at the 4 th floor, while the peak PFR on the windward side occurs at the 3 rd floor. When the pollutant is released on the top floor, the highest PFR occurs at the 4 th (windward) and 6 th (leeward) floors. Leeward R k (re-entry ratio) increases exponentially with the height of pollutant released floor, demonstrating greater sensitivity than that of the windward side. When all floors are ventilated, leeward R k remains higher than the windward side. Bottom floor pollutants rise upward along the leeward façade and descend on the windward facade, whereas top floor pollutants disperse both upward and backward on the windward façade. The findings of this study deepen the understanding of inter-floor interactions of ventilation performance in multi-story buildings and may provide guidance for the suitable window opening behavior for better ventilation performance under pollutant source release.",
