Scientists Develop Passive Cooling Technologies to Reduce Building Temperatures and Energy Use
Researchers worldwide have developed various passive cooling technologies to reduce building temperatures and energy costs without electricity. Innovations include rooftop tiles with self-adjusting vents, cement-based paints that evaporate moisture, smart windows that reflect and radiate heat, zigzag-shaped walls that direct heat skyward, and reflective roof coatings combined with evaporative cooling. These solutions demonstrate significant temperature reductions in tests, offering promising, energy-efficient alternatives to conventional air conditioning, though further development is needed for widespread adoption.
