Smart schools: previsione dei risparmi energetici conseguibili

Recent surveys demonstrate that Italian school buildings are energy inefficient, characterized with primary energy requirements of about 130-160 kWh/m2 year. Such a bad performance is sometimes due to the old building construction age and to the low construction quality. Moreover the systems management is often affected by an inaccurate set-up and control. Smart schools: previsione dei risparmi energetici conseguibili The recent Ministry of Education (MIUR) guidelines (MIUR, 2013) suggest a customized space suitability for a better educational effectiveness. A “smart” system flexibility is needed too, including the remote management and monitoring. The Building Automation and Control Systems (BACS) are still almost unused in Italy despite their energy saving potential. BACS sensors can measure the correct energy demand and provide the exact needed, avoiding energy wastes or losses. In this report different automation techniques were chosen among the ones listed in EN 15232 standard (EN, 2007). A dynamic simulation was launched to evaluate the energy saving of a reference building, representing the Italian school building stock. The results are relevant even with the only application of every technical solution. The combination of different solutions increases the overall performance. A primary energy requirements reduction of about 30% can be achieved, ensuring a great economic saving.
