This master’s thesis analyses the thermal behaviour of a public health centre located in Paterna, Spain, equipped with a hybrid HVAC system consisting of a geothermal and an aerothermal heat pump. The dynamic simulation was performed using EnergyPlus and OpenStudio, integrating operational data from the 'Cooling Down' project sensors and official technical documentation. The model includes the thermophysical characterisation of the building envelope, internal heat gains, and the seasonal control logic of the system. Model validation was conducted by comparing simulation results with actual electricity consumption and measured power logs. The study enabled an assessment of the system's efficiency and the definition of retrofit strategies aimed at optimising the building’s energy performance.
Il presente lavoro di tesi magistrale analizza il comportamento termico di un centro sanitario situato a Paterna, Spagna, dotato di un sistema HVAC ibrido composto da una pompa di calore geotermica ed una aerotermica. La simulazione dinamica è stata realizzata tramite i software EnergyPlus e OpenStudio, integrando dati operativi provenienti dai sensori del progetto "Cooling Down" e documentazione tecnica ufficiale. Il modello include la caratterizzazione termofisica dell'involucro, i carichi interni e le logiche di controllo stagionale del sistema. La validazione del modello è stata effettuata confrontando i risultati della simulazione con i consumi elettrici reali e i registri di potenza misurati. Lo studio ha permesso di valutare l'efficienza dell'impianto e di definire strategie di retrofit mirate all'ottimizzazione delle prestazioni energetiche dell'edificio.

Abstract
This master’s thesis analyses the thermal behaviour of a public health centre located in Paterna, Spain, equipped with a hybrid HVAC system consisting of a geothermal and an aerothermal heat pump. The dynamic simulation was performed using EnergyPlus and OpenStudio, integrating operational data from the 'Cooling Down' project sensors and official technical documentation. The model includes the thermophysical characterisation of the building envelope, internal heat gains, and the seasonal control logic of the system. Model validation was conducted by comparing simulation results with actual electricity consumption and measured power logs. The study enabled an assessment of the system's efficiency and the definition of retrofit strategies aimed at optimising the building’s energy performance.| File | Dimensione | Formato | |
