![]() ![]() "What we're seeing is the overall neighborhood effect that the air itself is cooler and that's even actually shifting with the wind downstream," said Wall. GAF uses a modified electric golf cart to take all kinds of temperature readings, from surface to air to what's called mean radiant temperature, which is an ideal measurement for how humans will physically experience heat - and the main measurement used in Turner's study identifying heat load.īut preliminary research by GAF - that has yet to be confirmed by outside researchers - found the coatings helped cool the air temperatures for the 10-block area by three degrees during the record-long and hot heat wave in early September 2022. And GAF designed it to be more durable than traditional asphalt coatings, according to the company. Bureau of Engineering for grip in wet weather and performs just as well as normal asphalt. Wall said GAF's proprietary blend of acrylic-based rather than asphalt-based cool paint doesn’t have that same heating impact above the surface. Cool pavement is no silver bullet, but it’s relatively quick and cheap to apply and can have an immediate effect (GAF paid for the project in Pacoima).
