This paper evaluates the thermal resilience of naturally ventilated classrooms in a public elementary school in Campinas, Brazil, considering the impacts of heatwaves and climate change. The methodology included on-site monitoring, computational model calibration, analysis of 10 years of heatwave data, and simulations of current and future climate scenarios. The indicators used were IOD (Indoor Overheating Degree), recovery time, PHFT (Percentage of Hours in the Temperature Range), and cooling load. The November 2023 heatwave resulted in 100% of occupied time outside the comfort zone, with a recovery time of 52 hours. Future scenarios indicated a reduction of up to 50% in PHFT and an increase of up to 121% in cooling load, reaching 269 kWh/m².year. The results highlight the urgent need to adapt school buildings to withstand more extreme future conditions.
