Third Derivative and RMI are collaborating to advance passive daytime radiative cooling (PDRC) solutions to address the increasing cooling demand and reduce greenhouse gas emissions from traditional air conditioning. These technologies have the potential to lower indoor temperatures sustainably and affordably without electricity. Pilot projects in the US and India, supported by partners like the Autodesk Foundation and the Bezos Earth Fund, will test the performance, affordability, and scalability of PDRC products. RMI's Global Cooling Initiative focuses on sustainable cooling solutions, while Third Derivative's Global Cooling Innovations page offers more information on innovative cooling solutions. Together, these efforts are crucial for expanding access to zero-energy cooling solutions in heat-vulnerable regions and advancing towards a more equitable climate future.
