## 5 Conclusions  
We have analyzed the primary school campus layouts in Xi'an and identified four common architectural floor plan forms based on existing design specifications and theories. Simulations were performed to examine the performance of four common campus layout forms in winter, summer, and indoor wind environments. This led to the discovery of the best layout scenario. The main findings of this study are as follows:  
1. Regardless of the scenario adopted, in the downtown area, due to the dense surrounding buildings, there is a certain degree of wind obstruction and a deceleration effect on the prevailing wind, ensuring that the outdoor wind speed in winter can meet comfort requirements. 2. The adoption of row-by-row floor planning results in the best performance in both indoor and outdoor wind environments. This is primarily because, under the condition of the average outdoor wind speed being within the comfort range, row-by-row floor planning allows the wind to easily traverse the entire site, effectively improving indicators such as outdoor wind speed, wind speed amplification factor, vortex areas, and still wind areas. At the same time, it also facilitates indoor air exchange rates and wind speed. 3. The scenario with zigzag floor planning performed the worst, primarily because the building form significantly obstructs the wind, preventing it from continuing to flow after entering the building. This negatively impacts indicators such as outdoor wind speed, wind pressure difference between the windward and leeward facades of the building, and indoor wind speed. Branching floor planning is similar to zigzag floor planning, but it breaks down the larger semi-enclosed spaces in zigzag floor planning, increasing the likelihood of the wind continuing to flow. Therefore, its performance is better. 4. When adopting enclosed floor planning, it is necessary to leave gaps on the windward and leeward sides to ensure airflow within the enclosed space. However, due to the funneling effect within the gaps, the wind speed may increase. Therefore, the gaps should be as large as possible. In conclusion, in the design of primary school campuses, it is crucial to adopt row-by-row floor planning to the greatest extent possible, enabling wind to traverse the entire site. When implementing zigzag floor planning, branching floor planning, or enclosed floor planning, it is necessary to create gaps on the windward and leeward sides to ensure airflow while avoiding excessively small gaps that could lead to excessive wind speeds within the gaps. This study identified four representative floor plan types and assessed their impact on the wind environment and classroom ventilation. The findings underscore the potential of these four types to provide universal guidance for the design of primary school building layouts and floor plans, offering valuable recommendations for future campus planning and construction. This study also has some limitations. For instance, only four typical models were selected for analysis, excluding more complex architectural floor plan forms for campus buildings. Additionally, only the dominant wind directions in winter and summer were chosen as the study conditions, leaving wind environment performance under other wind directions and speeds as an area worthy of further exploration in future work. Future research should further address the limitations of current studies by enhancing model diversity and incorporating a diverse range of wind directions and speed conditions. This approach will contribute to the in-depth advancement of research in the field of campus building wind environments. **Author Contributions:** Data curation, T.H. ; Formal analysis, M.L. ; Funding acquisition, Z.P. ; Investigation, M.L. ; Methodology, Z.P. ; Project administration, Z.P. ; Resources, M.L. ; Validation, M.J. and M.L. ; Visualization, N.J.; Writing--original draft, Z.P. ; Writing--review & editing, Z.P. and X.H.
