Decarbonization Avenue University research @ CLIMAX

Radiative cooling. Solar heat. All from one system, no electricity needed.

The study describes passive cooling system that aims to help impoverished communities, reduce cooling and heating costs, lower CO2 emissions.

Lowered the temperature inside a test system in an outdoor environment under direct sunlight by more than 12 degrees Celsius.

Lowered the temperature of the test box in a laboratory, meant to simulate the night, by more than 14 degrees Celsius.

Simultaneously captured enough solar power that can be used to heat water to about 60 degrees Celsius.
