We’ve developed radiative cooling materials that use the sky as a renewable resource for cooling
SkyCool Systems’ patented technology turns the sky into a renewable resource for cooling by rejecting heat into the cold universe.
The SkyCool team was the first to demonstrate that the natural phenomenon of radiative cooling can be used during the day, and SkyCool Systems is the first company to employ radiative sky cooling with air conditioning and refrigeration systems.

Our technology is accelerating the transition to a cleaner and more sustainable future!
SkyCool Radiative Cooling Film and Panels
We invented passive daytime radiative cooling and we are using the technology to make products that improves the efficiency of any air conditioning or refrigeration system and lower cooling loads in buildings.
We apply our passive cooling film to panels to reduce energy use for cooling, and we are commercializing the film as a roof coating. The film reflects sunlight to prevent any surface its in contact with from heating up during the day and it also emits infrared heat to the cold sky, which keeps it cool 24/7/365.
SkyCool’s panels can be used as an add-on to air conditioning and refrigeration systems. In some circumstances, our panels can even replace an air conditioning unit. As an add-on, our panel system will yield between a 10% to 40% efficiency improvement depending on the integration mode. When fully replacing an air conditioning system, we expect an 80% to 90% energy reduction for cooling.

A SkyCool panel saves 2x -3x as much energy as a solar panel generates given the same area.
Compared to solar panels, SkyCool Panels utilize roof-space more effectively by providing cooling 24/7. Since SkyCool panels do not need to be south-facing, they can complement solar panels on the roof.

We’re focused on deploying SkyCool Panels and Film in commercial and industrial applications where cooling is a dominant load.

Passive Cooling Film
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 films are 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.
Dual-Mode Film serves numerous applications

Applied to outdoor batteries or electronic boxes

shaded structures

Applied on
metal roofs

Applied to refrigerated
trucks or other vehicles
