text: The commercialization of passive daytime radiative cooling technologies is in an early stage of development.
  SkyCool Systems, founded by Aaswath P. Raman, who authored the scientific breakthrough study demonstrating the use of photonic metamaterials in making PDRC possible, is a startup that is commercializing radiative cooling technologies. SkyCool panels have been applied to some buildings in California, reducing energy costs. The company has received a grant from the California Energy Commission for further application opportunities.
  3M, an American multinational corporation, has developed a selectively emissive passive radiative cooling film. The film has been applied through pilot programs that are open for expansion. The film was tested on bus shelters in Tempe, Arizona. 3Ms film achieved "10–20% energy savings when deployed on SkyCool Systems panels and integrated with a buildings HVAC or refrigeration system."

Radi-Cool products have been applied in many areas such like airport (Singapore, [https://haneda-airport-business.com/en/radicool.html Japan]), office building and big mall (Philippines, Malaysia), warehouse industrial (Germany, Latin America), etc. They have grown rapidly and have expanded the distribution all over the world. Their film and coating can help the world to reduce the carbon dioxide emission and create an eco-friendly environment.

They supply Radi-Cool products for commercial and industrial application in the American Southwest.
