Researchers at the University College London have put forth a new argument in favor of a simple solution to combating the issue of extreme heat in cities without air conditioning. The so-called “cool roof” method they found had the best mitigation performance metrics over others surveyed... View full entry
Scientists in the US have developed a paint significantly "whiter than the whitest paint currently available".
Tests carried out by researchers at Purdue University on their "ultra-white" paint showed it reflected more than 98% of sunlight.
That suggests, the scientists say, that it could help save energy and fight climate change.

The paint's whiteness opens up a range of cooling features that, applied at an industrial scale, could limit the built environment's contributing effect to global warming and its dependency on traditional air conditioning. "If you were to use this paint to cover a roof area of about 1,000 square... View full entry
Powerhouse Company's "Paper Roof," the new design for a reception center in Tianjin, China has been completed.

It is well established that white roofs can mitigate the urban heat island effect, reflecting the sun's energy back into space and reducing a city's temperature. In a new study of Guangzhou, China, researchers found that during a heat wave, the effect is significantly more pronounced. Reflective roofs, also called cool roofs, save energy by keeping buildings cooler, thus reducing the need for air conditioning. — Science Daily
According to a new study by Berkeley lab researchers Dev Millstein, Ronnen Levinson, and Pablo Rosado, alongside Meichun Cao and Zhaohui Lin of the Institute of Atmospheric Physic in Beijing, so-called "cool roofs," or roofs painted white, substantially reduce the urban heat island effect during...
