Radiation cooling is a passive cooling technology that can cool a room without the use of an external energy source. With the use of suitable materials, the reflection of sunlight and the radiation of heat in the outer space is achieved, which functions as a large storehouse of heat. The purpose of the phenomenon is to cool the material and whatever surrounds it. For this purpose, three different materials were modeled in the MATLAB work environment and 11 different atmospheres in the MODTRAN work environment. The first material, a coating consisting of layers of hafnium dioxide (HfO2) and silicon dioxide (SiO2). Second material, a coating of poly (vinylidene-fluoride-co-hexafluoropropene) (P(VDF-HFP)) and the third material, a coating consisting of two layers of aluminum dioxide (Al2O3) and silver (Ag). After studying the meteorological data of the area, three representative days were selected, in which we would check the performance of the materials. With the help of the necessary equations the cooling power and the temperature of the material was calculated throughout the day for each of our scenarios. The temperature of each material in different atmospheres was analyzed as well as the behavior of it when basic atmospheric characteristics change, such as humidity.
