Researchers Develop Passive Cooling Technologies to Reduce Building Energy Use
Researchers have developed various innovative passive cooling technologies to reduce reliance on energy-intensive air conditioning. These include porous PMMA sheets reflecting sunlight to lower temperatures by 15°F, two-layer polymer films mimicking skin's evaporative cooling, aluminum-coated films emitting heat to outer space, transparent window coatings blocking solar heat while allowing light, and fluid-filled microchannel windows that adjust heat and light transmission. These advancements aim to improve building energy efficiency and indoor comfort without electricity, showing promise for future sustainable cooling solutions.
