Riqualificazione energetica del patrimonio edilizio scolastico recente: metodo S.C.O.R.E.S. per la valutazione degli impatti delle strategie sostenibili di intervento

The construction sector is responsible for 36% of greenhouse gas emissions and 40% of total energy consumption in the EU, the energy retrofitting of existing buildings is crucial for environmental sustainability. In Italy, over 41,000 school buildings consume substantial energy, with many of them not meeting current standards. Barriers to renovation include high initial costs, insufficient funding, complex building conditions, and issues related to school activities’ interruption. In this context, decision support tools are essential. The “S.C.O.R.E.S.” method is an expeditive procedure to compare different intervention scenarios highlighting long-term benefits and facilitating the process by providing user-friendly interfaces accessible to non-experts. S.C.O.R.E.S. can analyze four scenarios and rank them based on users’ priorities and building performance (energy, environmental, and eco- nomic aspects) using various Key Performance Indicators. The proposed method has been applied and validated in several residential and service buildings. This paper shows the application to a specific educational building “Scuola Secondaria di I grado Besta”, built in the late 1970s in Bologna. The results demonstrate the method’s potential, showing how engaging users and highlighting the financial and environmental benefits of retrofitting can promote acceptance and foster energy-efficient building initiatives.
