Researchers Develop Passive Cooling Materials to Reduce Air Conditioning Energy Use
Researchers have developed innovative passive cooling materials and systems that reduce reliance on electricity for air conditioning. Studies from Penn State, Princeton, Wuhan University, and others demonstrate porous plastic sheets and multilayer films that reflect sunlight and emit thermal radiation, achieving temperatures significantly cooler than ambient air. These technologies combine radiative and evaporative cooling with natural airflow, offering promising applications in building design to improve energy efficiency and indoor comfort without mechanical systems.
