What We’re Following

Mirror, mirror on the road: Covering blacktop with white paint to beat the heat makes intuitive sense: Dark surfaces absorb heat from sunlight, while lighter colors reflect more of that light. With plenty of asphalt to go around, Los Angeles is deploying white paint known as “cool pavement” with zeal to combat the urban heat island effect. But there’s a little problem with painting the street white: It may be reflecting heat back onto people.

(Los Angeles Bureau of Street Services)

The revelation comes from new research at UCLA that found the reflective surfaces could actually make pedestrians feel 7 degrees hotter on a typical L.A. summer day. The results, provided exclusively to CityLab in advance of their publication, are the first known real-world, empirical assessments of how cool pavements affect the human body. But they likely won’t be the last assessment. The finding hasn’t deterred L.A. from continuing the program, and there is lots more to study, from the benefits of painted roofs rather than roads, to how new trees might mitigate the pavement’s warming effect.
