In a proactive initiative starting in 2011, volunteers in New York City painted rooftops white to tackle the challenges of urban heat. This innovative approach effectively decreased the absorption of sunlight, resulting in cooler indoor environments. By lowering indoor temperatures and minimizing air conditioning use, the widespread implementation of white roofs holds the potential to significantly reduce both neighborhood heat and overall energy consumption.

Manchester study finds air conditioning use can be reduced if building exteriors can be cooled

Cities have a habit of storing heat. Roads, walls and rooftops absorb sunlight during the day and slowly release it back into the surroundings after sunset, leaving built-up areas…
