When a heatwave hits, temperatures in cities can become even more extreme as all that concrete and asphalt absorbs a ton of sunlight. One Los Angeles neighbourhood is testing out a new strategy to ...

To combat the so-called urban heat island effect, some cities have been retrofitting public buildings into climate shelters, while others have been planting thousands of trees. One Los Angeles ...

Cities across the U.S. have found relief from this summer’s record-setting heat with the help of technologies that shield roofs, pavement and other surfaces from the sun’s scorching rays. Some of ...

Shanae LaSalle Munford, of Elk Grove, walks through DoCo with water after running errands during record-breaking heat as downtown Sacramento reaches 116 degrees Tuesday, Sept. 6, 2022, according to ...

Heating and cooling needs in commercial buildings and our homes account for an extraordinary amount of our global energy needs. In fact, an International Energy Agency report suggests that 20% of all ...

It’s common sense: When it’s hot outside, don’t put on a dark shirt—wear white instead. A team of researchers at Purdue University has put this common knowledge to work to figure out ways to cool ...

New research from Purdue University has helped develop a white paint that has a solar reflectance of 97.9 percent, which can help keep objects painted with it cooler. A development of an older ...

Just like a tennis player might don a white shirt instead of a black one on warm summer's day, researchers see great potential in dressing buildings in reflective white paints to keep them cool. A ...

A new superwhite paint is so reflective that it can cool a surface to below the surrounding air temperature, even under sunlight. It could help reduce the use of energy-intensive air conditioning in ...

A layer of dark paint effectively reflects the Sun’s rays if it’s just the right thickness and has an undercoat of white paint — allowing coloured surfaces to be made cooler. Reflective white paint ...

Heating and cooling account for huge portions of our energy consumption and environmental impact, so systems that can passively control indoor climate are important. Now scientists at Stanford have ...
