Retrofit of an existing school in Italy with high energy standards

The Tito Maccio Plauto school was built in Cesena during late sixties and, conformingly to the period construction technologies and standards, is characterized by poor energy performances. The retrofit of the school is implemented in the framework of the School of the Future Project, funded by 7th Framework Programme. The objective is demonstrating the technical economical feasibility of deep energy renovation for public buildings, bound to last several decades after, avoiding the land use for new construction and improving the energy performances of the existing building stock. The actual consumptions for the different energy services were monitored and the occupancy profile of the school zones was analyzed. Starting from the preliminary monitoring it was possible to design the most suitable energy to achieve the initial targets: reduction of factor 4 of space heating energy uses, reduction of factor 3 of the overall energy uses. The measures involved: external insulation of façades and roof, partial insulation of the ground floor, replacement of windows with external moveable shading devices, complete renovation of the heating system, design and installation of a remote energy management system for the municipality schools, installation of a PV plant on the roof, mechanical ventilation system for classrooms. The last measure was implemented to fulfill the improvement of the indoor environment quality, another crucial issues the EU Project had to couple with. Detailed analyses, carried out with dynamic and national reference calculation tools, demonstrated the efficacy of the implemented measures, since all the relevant target were reached, as will be monitored during the monitoring phase of the project.
