In many developing nations, most formal educational facilities are designed and built without active ventilation to reduce costs, relying solely on passive cooling. In spite of this trend, the influence of plan shapes on the effectiveness of passive cooling in educational facilities situated in warm humid tropics has not been thoroughly researched. The research objective is to examine the impact of building plan shape on the desired natural ventilation required for thermal comfort in the classroom buildings of government owned primary schools located in Enugu city, south-eastern sub-Saharan Nigeria. A hybrid research design, encompassing both experimental and survey methods, was implemented to evaluate the outdoor and indoor climates of sixty school structures in the metropolitan area, utilizing two thermo-anemometers (AZ 9871). The selection of these structures was based on a stratified random sampling technique. To analyze the data, the global ventilation coefficient (G), building total opening wall area (TOA) to floor area (FA) ratio standards, and linear regression analysis were employed. The findings of this study indicate a significant correlation between classroom plan shape and effective natural ventilation. Furthermore, the results demonstrated that 25% was the mean TOA/FA of all classroom buildings examined, falling within the recommended range of 20%–30%. These ratios positively influenced effective natural ventilation and ultimately impacted their thermal conditions. The study surmises that the design of classroom buildings should adequately prioritize square plan shape and wall openings to ensure optimal natural ventilation.
