Buildings coated in a cement-based paint that “sweats” could help keep communities cool during the hottest days of the year. The substance is known as CCP-30, and its creators say initial tests ...

Air conditioners and other cooling systems are among our biggest consumers of electricity. Now researchers have developed a hybrid device that can not only cool buildings drastically without using ...

Dubbed photonic radiative cooling by the researchers, the process relies on a coating made of a combination of silicon dioxide (SiO2) and hafnium oxide (HfO2) set on a thin layer of silver.

The new passive cooling system addresses an important problem in the field: how radiative cooling can work during the day and in crowded urban areas. “During the night, radiative cooling is easy ...

Unlike previous attempts at cooling coatings, the new UMD-developed glass is environmentally stable -- able to withstand exposure to water, ultraviolet radiation, dirt and even flames, enduring ...

Passive cooling, like the shade a tree provides, has been around forever. Recently, researchers have been exploring how to turbo charge a passive cooling technique — known as radiative or sky cooling ...

Air conditioners are gradually becoming more common here as well—but they consume vast amounts of energy. A newly developed ...

Passive radiative cooling utilizes that thermal energy can leave an object in the form of infrared radiation. All objects emit heat as infrared light -- trees, buildings, water and even humans.

The development of efficient cooling technology based on environmentally friendly and biobased materials is crucial to many day-to-day activities. A novel, highly efficient cellulose nanocrystal ...

Objects emit electromagnetic radiation with a spectrum that peaks at a particular wavelength depending on the object’s temperature. Radiative cooling exploits the fact that the peak at room ...

A new passive radiative “cooling wood” that reflects infrared radiation could reduce the energy costs associated with cooling buildings by between 20 and 60%. The material, which is more than eight ...

A newly engineered, wood-based material successfully reflects heat, or infrared radiation, and could cut the energy costs associated with cooling buildings by up to 50%, according to a modeling ...
