A technical study by Saint‑Gobain Solutions Portugal highlighted that low‑performance HVAC ductwork in Portuguese buildings can waste over 7,000 kWh annually, costing more than €1,000 per year for a typical 200 m² service building. The study promoted the CLIMAVER® pre‑insulated duct system as a way to cut energy loss and carbon emissions. In response, the municipality of Loulé allocated €200,000 to survey thermal comfort and energy needs in its public schools, preparing for future air‑conditioning installations and supporting its climate‑action goals.

Within weeks, other Portuguese municipalities announced concrete steps to improve school environments. In the village of Cuba, a former primary school was converted into the Space C living laboratory, featuring nature‑based solutions such as a constructed wetland, rain garden, green roof and rain‑water harvesting, all co‑financed by the EU Interreg Euro‑MED programme URWAN. Meanwhile, the council of Abrantes committed to installing air‑conditioning systems in all its schools for the next academic year, citing more frequent heatwaves. Funding of €9,000 was approved for a specific school in Tramagal, illustrating a broader municipal push to enhance learning conditions and urban resilience across Portugal.
