This very satisfying drone footage shows an innovative plan to reduce temperatures in Los Angeles by sealing streets with a reflective sealant.
Via Arch Daily:
Last spring, the Los Angeles Bureau of Street Services tested a new, creative approach to combat the rising temperatures in the city center. The pilot project covered one neighborhood street in each of the LA’s 15 council districts with CoolSeal, a more reflective asphalt-based coating developed by California-based company GuardTop. After seeing a difference of 11-13 degrees Fahrenheit on the coated streets, Los Angeles and other cities plan on implementing more reflective roofs and pavements to reduce the side effects of “heat islands.”
Here’s a quick explainer from when the program started
