How Reflective Paint Brings Down Scorching City Temperatures

Eric Niiler of The Wall Street Journal reports on cities that are using reflective paint to lower temperatures.

The C3 Take
  • Cities, which disproportionately suffer from extreme heat due to a lack of green space and surplus of hard infrastructure, are turning to reflective paint to bring down temperatures.
  • The Los Angeles neighborhood of Pacoima, which is heavily industrialized, has partnered GAF, a New Jersey-based roofing manufacturer, to paint basketball courts, local parks, and neighborhoods with reflective coatings.
  • These reflective coatings have reduced air temperatures in the test area by 3.5° F on extreme heat days and surface temperatures by 10°.
  • Private sector innovation is creating environmental solutions and progress.

“Cooling technologies mitigate this. Green roofs absorb heat before it penetrates the buildings beneath. Super-reflective coatings reflect the sun’s visible light and invisible infrared radiation away from surfaces to keep them cooler. And an ultra-white paint developed at Purdue University promises even more protection, although the product isn’t commercially available yet. Each strategy helps reduce energy use.”
