Overview

• A Barcelona nursery with a broken air-conditioning system since last September recorded nearly 30 °C indoors and saw a 2-year-old suffer a heat stroke as promised portable units remain undelivered.
• Families at Seville’s CEIP Borbolla and other Andalusian schools have staged demonstrations after classrooms climbed above 35 °C amid obsolete electrical infrastructure and insufficient temporary cooling measures.
• The Andalusian Bioclimatization Law approved in 2020 has been applied to just 10 % of public schools, and many adiabatic cooling systems are unused due to lack of maintenance funding.
• In Castilla-La Mancha, the STE-CLM union has decried classrooms as “insostenible” ovens and criticized a regional plan as limited to certain schools, underfunded and missing execution guarantees.
• Researchers from the CSIC warn that Spain’s summer thermal period could exceed 155 days by 2050, bolstering calls for energy retrofits, efficient cooling installations and heatwave-ready school protocols.
