This study aims to decarbonize offices in developing nations by proposing a comprehensive methodology for conducting remote energy audits in these countries and testing it through a case study. Focusing on the FAO context, the latest European standard for energy audits was modified to meet its specific needs: a data check passage was added after the data collection phase, while for the energy model two different simulating software with two cost configurations are used, covering as many future operating conditions of the compounds as possible, which are often uncertain in developing countries. The proposed innovations are evaluated in different scenarios and configurations, reducing the uncertainty inherent in remotely conducted energy audits. For the case study, an energy audit was performed on an FAO office in South Sudan that is solely powered by a diesel generator. Data was collected and evaluated following the proposed methodology, resulting in the development of current and future energy models. Various alternatives were tested, with the ideal outcome being a configuration employing increased roof insulation, the replacement of the boiler with a heat pump, and the installation of a solar hybrid system to cover the building load, as well as a new efficient diesel generator as a backup. With this approach, fuel consumption can be decreased by up to 87% compared to the baseline scenario, resulting in enhanced environmental and financial benefits.
Questo studio mira a decarbonizzare gli uffici nei paesi in via di sviluppo proponendo una metodologia dettagliata per la conduzione da remoto di audit energetici in queste nazioni, testandola tramite un caso studio. Adattandosi al contesto FAO, la norma europea di riferimento per gli audit energetici è stata modificata per soddisfarne le esigenze: è stato aggiunta una fase di controllo dopo la raccolta dati, mentre per il modello energetico vengono utilizzati due software diversi con due diverse configurazioni di costi per considerare il maggior numero possibile di condizioni operative future dei compounds, essendo queste spesso incerte in paesi in via di sviluppo. Le innovazioni proposte vengono così valutate in diversi scenari e configurazioni, riducendo l'incertezza insita negli audit energetici condotti a distanza. Per il caso studio, è stato eseguito un audit energetico su un ufficio FAO in Sud Sudan, al momento alimentato esclusivamente tramite generatore diesel. I dati sono stati raccolti e valutati seguendo la metodologia proposta, con conseguente sviluppo di modelli energetici attuali e futuri. Sono state testate diverse alternative, ottenendo come risultato ottimale una configurazione che prevede un maggiore isolamento termico del tetto, la sostituzione della caldaia con una pompa di calore e l'installazione di un sistema solare ibrido in grado di alimentare l'edificio, oltre ad un nuovo efficiente generatore diesel come backup. Con questo approccio, il consumo di carburante può essere ridotto fino all'87% rispetto allo scenario di riferimento, con conseguenti benefici ambientali ed economici.

Abstract
This study aims to decarbonize offices in developing nations by proposing a comprehensive methodology for conducting remote energy audits in these countries and testing it through a case study. Focusing on the FAO context, the latest European standard for energy audits was modified to meet its specific needs: a data check passage was added after the data collection phase, while for the energy model two different simulating software with two cost configurations are used, covering as many future operating conditions of the compounds as possible, which are often uncertain in developing countries. The proposed innovations are evaluated in different scenarios and configurations, reducing the uncertainty inherent in remotely conducted energy audits. For the case study, an energy audit was performed on an FAO office in South Sudan that is solely powered by a diesel generator. Data was collected and evaluated following the proposed methodology, resulting in the development of current and future energy models. Various alternatives were tested, with the ideal outcome being a configuration employing increased roof insulation, the replacement of the boiler with a heat pump, and the installation of a solar hybrid system to cover the building load, as well as a new efficient diesel generator as a backup. With this approach, fuel consumption can be decreased by up to 87% compared to the baseline scenario, resulting in enhanced environmental and financial benefits.File | Dimensione | Formato | |
