In 2011, New York painted its black rooftops white; monitoring found its average peak summer surface temperature was 43°F lower

New York City tested painting dark rooftops white to combat urban heat. Reflective white paint significantly lowered roof surface temperatures compared to dark surfaces. This simple method reduces heat absorption, benefiting buildings and neighborhoods. Widespread adoption of cool roofs can decrease cooling energy demand across cities. The experiment demonstrated how basic engineering can yield powerful, practical results.
