- Skycool Systems — At SkyCool Systems, our mission is to deliver sustainable, energy-efficient cooling solutions to customers interested in reducing energy costs and carbon footprint. We’ve pioneered radiative cooling as a technology, and shown that specially designed optical films can enable this passive approach to cooling throughout the day. These optical filmsare highly reflective to sunlight but also emit thermal radiation exceptionally well to the cold of space through our atmosphere, enabling daytime operation during the hottest hours of the day. Our core innovation is a rooftop cooling panel. We apply the radiative film to rooftop panels and integrate them with air conditioning and refrigeration systems. The panels can be used as an add-on to air conditioning and refrigeration systems and in some circumstances even replace an air condensing unit. Our technology is accelerating the transition to a cleaner and more sustainable future.
