The refurbishment and improvement of the existing building heritage is getting more and more significant also in the field of school building. In this sector, the interventions related with energy efficiency and improvement, in terms of environmental sustainability of the building, are critical, and nowadays, involving several schools in Puglia thanks to the “Protocollo Itaca 2009 Puglia – Edifici Pubblici non residenziali" (Itaca Protocol 2009 Puglia - Public non-residential buildings"). In the framework of these activities Flag Soprema Group is giving its contribution supplying materials that, beside ensuring a fit waterproofing of the covering, allow reducing the overheating of the surfaces thanks to a high reflectance power of the sun rays incident on the same surfaces.
The work performed in the School Papa Giovanni XXIII in San Ferdinando di Puglia (BT) where approximately 2000 square meters of the roofing have been restructured thanks to the polyolefin membrane Flagon EP/PR 1.5 RAL 9016, set with mechanical fixing onto the structure is a clear example of this commitment. The use of Flagon EP/PR 1.5 mm RAL 9016 besides improving the summer performance of the building, thanks to its high SRI (Solar Reflection Index) allowed reaching excellent results in the following assessment criteria included in the ““Protocollo Itaca 2009 Puglia – Edifici Pubblici non residenziali" (Itaca Protocol 2009 Puglia - Public non-residential buildings")
3.3.1 – ROOFING with URBAN HEAT ISLAND EFFECT– This criterion favours the use of materials with high reflection coefficients to reduce significantly the increase of air temperature near the roofing.
2.3.6 – BIOSUSTAINABLE MATERIALS – This criterion favours the use of materials with acknowledged eco-quality brand for the casing of the building.
These elements, together with a correct thermal insulation, will grant a significant energy saving and improve the thermal comfort of the classrooms besides enhancing the living well-being of students and teachers.
