L’adeguamento sismico ed il miglioramento energetico delle strutture sono diventati al giorno d’oggi una priorità. Buona parte del patrimonio edilizio esistente si trova in stato di grande obsolescenza strutturale, architettonica ed energetica. Oltre alla prevenzione, tuttavia, un aspetto molto importante riguarda la riparazione e riqualificazione degli edifici resi inagibili dagli eventi sismici recentemente accaduti nel territorio nazionale. In modo particolare, nel presente articolo verrà preso in considerazione un edificio del plesso scolastico sito nel Comune di Pievebovigliana, provincia di Macerata, danneggiato dai terremoti che hanno colpito l’Italia centrale il 24.08.2016 e il 30.10.2016. Nel dettaglio si farà riferimento ad un edificio isolato, adibito a scuola elementare e media e sviluppato su un piano fuori terra con pianta fortemente irregolare. Sono qui analizzate e dimensionate differenti possibilità di intervento di adeguamento sismico e miglioramento energetico valutandone i potenziali carichi ambientali e i possibili scenari futuri. Pertanto oltre alla sicurezza strutturale e all’incremento delle prestazioni energetiche sono valutati gli impatti ambientali relativi a ogni intervento in modo da poter adottare un criterio di progettazione integrato in un’ottica “Life Cycle Thinking”.

Abstract

The improvement of seismic performances and the enhancement of the energy efficiency of existing buildings have nowadays become a priority. Indeed, much of the existing building stock is characterized by great structural, architectural and thermal obsolescence. In addition to the renovation of existing buildings, a very important aspect is the repair and upgrading of buildings recently damaged by the seismic events that hit the Italian territory. In particular, this article takes into account a school located in the municipality of Pievebovigliana, province of Macerata, which got damaged by the earthquakes that hit Central Italy on 24.08.2016 and 30.10.2016. In detail, the article refers to a one-story building characterized by an irregular plan configuration. The gravity load resisting system is made by masonry walls with regular blocks; in addition, few reinforced concrete columns embedded in the masonry walls support the roof girders. Different strategies of anti-seismic retrofit measures and thermal improvements are analyzed and dimensioned, assessing the potential environmental loads and potential future scenarios. In addition to the structural safety and to the enhancement of the energy performance, the environmental impact related to each retrofit action is assessed, therefore following a Life Cycle Thinking approach.
