Radiative coatings can passively cool buildings without the use of mechanical refrigeration equipment. Two recent papers describe the development of ceramic and glass radiative coatings that demonstrate resistance to environmental stimuli and potential for mass production.
Read MorePassive radiative cooling systems typically are implemented by applying special coatings to the walls or roof of a building. But windows play a significant role in heat transfer too. University of Notre Dame researchers used a quantum computing-assisted active learning scheme to develop a new high-performance transparent radiative cooling coating for windows.
Read MoreRadiative cooling paint offers a way to regulate temperature inside a building and reduce reliance on air conditioning. Researchers at Purdue University developed a new radiative cooling paint based on calcium carbonate that reaches 95.5% reflectance in the solar spectrum, substantially higher than the solar reflectance values of commercial radiative cooling paints.
Read MoreA trio of Stanford University researchers has developed a clear and protective cooling coating for solar cells that allows them to shunt away excess heat and improve efficiency.
