Il 28-30 settembre si è tenuto a Valencia la 40esima edizione del Congresso Internazionale di Architettura e Edilizia (EXCO 2026), durante il quale il Prof. Fulvio Re Cecconi l’Ing. Giacomo Caccia hanno presentato il paper e il poster: “The Impact of Elementary Renovation Actions on Italian Schools: Preliminary Outcomes from the RERoadS project”.
Sviluppato nell’ambito di del progetto RERoadS, lo studio valuta 14 interventi di riqualificazione su due archetipi scolastici in due climi distinti, Milano e Bari. I risultati mostrano che la forma e la distribuzione interna degli spazi dell’edificio incidono fortemente sui consumi, raggiungendo differenze fino al 55% in termini di energia primaria totale. L’aggiornamento dei sistemi di riscaldamento elettrici risulta l’intervento singolo più efficace. I dati evidenziano inoltre che le strategie più efficienti dipendono strettamente dal clima: al Sud sono preferibili rinnovabili e illuminazione, mentre al Nord occorre dare priorità a riscaldamento e involucro.
Si tratta di un passo fondamentale verso la creazione di roadmap di riqualificazione per scuole più confortevoli e sostenibili.
The ageing, energy-intensive Italian school building stock urgently requires extensive renovation to ensure comfort and sustainability for the millions of students it hosts daily. Within the framework of the RERoads project, two representative school archetypes (I- and R-shaped) were developed to support this transition and tested across two distinct Italian reference locations Bari (Climatic Zone C – Csa) in the south and Milan (Climatic Zone E – Cfa) in the north, to guide the creation of comprehensive renovation roadmaps. Fourteen Elementary Renovation Actions emerged from the literature were analysed on these models to evaluate their isolated impacts, to understand the most effective ones and to optimise their combinations based on total primary energy, operative costs, and operative CO₂ emissions.
Results demonstrate that the building archetype is a relevant driver for the baseline total primary energy, as the R-shaped archetype consistently requires over 55% more primary energy than the I-shaped model due to a higher surface-to-volume ratio and extended corridor spaces with lower internal gains for people. Universally, upgrading to energy-efficient electrical heating emerges as the most impactful single measure, reducing primary energy by up to 52% in Zone E. However, other efficient strategies depend strictly on climate: warmer climates benefit most from renewable energy integration and lighting upgrades due to lower heating needs, whereas colder regions require a rigorous prioritization of heating systems and envelope improvements.
