Study Finds Cool Roofs Most Effective for Urban Temperature Reduction

Research highlights cool roofs' superior performance over green roofs and other methods in lowering city heat.

Cool roofs can reduce outdoor temperatures in cities like London by up to 2°C.
Green roofs and street-level vegetation offer minimal cooling benefits compared to cool roofs.
Widespread use of air conditioning could increase outdoor temperatures in dense urban areas.
Cool roofs also help lower indoor temperatures by reflecting heat.
Trees and green roofs provide additional environmental benefits but are less effective in cooling.
