The aim of this master thesis is to analyze the daytime radiative cooling performance of a Passive Radiative Cooling (PRC) system, a technology able to deliver cooling without any electrical input. Due to this property, PRC technology finds significant application in the field of climate change mitigation. Global cooling demand is expected to rise from 36% in 2022 to 60% by 2050, leading to an increase in electricity consumption in the residential sector. This latter ranks as the second-most energy-intensive sector following the industrial one. Reducing energy demand means reducing the greenhouse gas (GHGs) emissions caused by fossil fuels combustion, which is the main source of heat and electricity production.
