The COVID-19 pandemic highlights the need for school designs that prioritize health, well-being, and sufficient natural ventilation rates, alongside engaging learning environments.In conventional double-loaded layouts, only one classroom typically aligns with optimal wind direction, achieving standard ACH rates.This study addresses research gaps by introducing two frameworks: EDS early design RO retrofitting existing educational structures.The framework optimizes faç ade variables a hypothetical to maximize average air velocity (AAV), while investigates within real case identify configurations meet ACH.Key parameters analyzed include Window-to-Wall Ratio (WWR), Opening-to-Wall (OWR), Faç height (FH) correlated AAV.The considered window/opening position, WWR, OWR associated needed improving environment.The included CFD-parametric optimization approach engaged developed GHPython codes linear regression analysis.CFD simulations specific scenarios were performed in assess analysis demonstrates key (OWR, FH) explain 33.1% of variance AAV, an AAV 0.65 m/s.Regression substantial positive impact on underscores negative influence facade height, aiding formulating strategies enhance indoor quality classrooms.The framework, applied classrooms Cairo, Egypt, versatility enhancing IAQ through WWR OWR.Simulations identified opening ratios: 20% W/OWR foundation-stage (ACH 6.94) 30% 10% primary-stage 7.33).These reduced infection risks below 1%, supporting findings from related studies risk, affirming framework's efficacy designing healthier environments.The frameworks offer valuable tools conditions classrooms; future may investigate across diverse settings user feedback be refine their real-world effectiveness.
