The international consensus is that reaching carbon emission peak and subsequent carbon neutrality are to be considered the main global challenges. Research shows that building energy consumption accounts for more than 35% of total energy consumption, of which HVAC (heating, ventilation, and air conditioning) systems account for 44%. Recently, radiative cooling has been widely studied as a passive cooling method, which can efficiently reduce the target temperature by increasing the thermal emissivity and solar reflectivity of the object surface.
