Space cooling is one of the main sources of energy consumption in buildings, and it is expected to keep increasing in the upcoming decades. In the context of climate change, it is important to assess its environmental and economic impact, given that the most common air conditioning systems are energy-intensive and responsible for the production of large amounts of greenhouse gases. Therefore, it is crucial to research and develop new technologies that mitigate these effects. One of the most advantageous and recently investigated solutions is Passive Radiative Cooling (PRC), a technology that exploits the Earth’s atmosphere transparency window (8-13 μm) to dissipate thermal radiation towards the outer space.
