Approccio "Life Cycle Thinking" applicato alla riparazione di una scuola danneggiata dal terremoto dell'Italia centrale

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.
