New 3D Reversible Technology Cuts Building Energy Consumption

Researchers at South Korea’s Daegu Gyeongbuk Institute of Science and Technology (DGIST) have developed a 3D reversible energy-saving device designed to help buildings adapt to changing temperatures and reduce energy consumption. The structure automatically switches between heating and cooling modes in response to ambient conditions, without relying on complex external control systems. The device uses a shape-memory alloy actuator alongside solar-absorbing and radiative-cooling materials to mana
