L’implementazione di soluzioni ingegneristiche volte alla minimizzazione dei flussi energetici in ingresso è una tematica chiave nello scenario economico odierno. Sempre maggiori utenti pubblici e privati desiderano ridurre la loro dipendenza energetica dalla rete nazionale investendo in efficienza energetica, per diminuire i fabbisogni, e fonti di energia pulita rinnovabile, per produrre energia in sito sfruttando eventualmente meccanismi incentivanti. Per far sì che questo avvenga, c’è la tendenza sempre più comune a rivolgersi a studi tecnici per selezionare le migliori opzioni e i sistemi energetici più avanzati per poter costruire edifici “quasi net-zero energy” o riqualificare degli immobili energivori preesistenti. Il seguente elaborato analizza un caso studio reale di efficientamento energetico, ovvero di miglioria di impianti di produzione di energia termica obsoleti. Inoltre, è considerata l’installazione di sistemi energetici a fonti rinnovabili, quali impianto fotovoltaico e pompa di calore aria-acqua, per la produzione di energia elettrica e termica rinnovabile. Ciò consentirà innanzitutto di decarbonizzare, ovvero ridurre l’impatto ambientale della struttura in termini di tonnellate di anidride carbonica immessa in atmosfera. Inoltre, saranno ridotti i consumi di energia primaria, punto chiave per quantificare l’incremento in termini di prestazione energetica dell’edificio, a seguito degli interventi.

Abstract
The implementation of engineering solutions aimed at minimizing energy input flows is a key issue in today's economic scenario. Increasing numbers of public and private users want to reduce their energy dependence on the national grid by investing in energy efficiency to reduce energy demand, and clean renewable energy sources, to produce energy on-site by possibly taking advantage of incentive mechanisms. To make this happen, there is an increasingly common tendency to consult engineering companies to select the best options and the most advanced energy systems to be able to construct "nearly net-zero energy" buildings or upgrade pre-existing energy-intensive properties. The following paper analyzes a real-life case study of energy efficiency, i.e., improvement of obsolete thermal energy production systems. In addition, the installation of renewable energy systems, such as photovoltaic system and air-water heat pump, for the production of renewable electricity and thermal energy is considered. This will firstly decarbonize, that is, reduce the environmental impact of the facility in terms of tons of carbon dioxide released into the atmosphere. In addition, primary energy consumption will be reduced, a key point for quantifying the increase in energy performance of the building, as a result of the interventions.| File | Dimensione | Formato | |
