The Extended Cooling Effect: The Role of Urban Green Roofs in Cooling Dense City Districts
A. The intensification of the Urban Heat Island (UHI) effect, a phenomenon where metropolitan areas are significantly warmer than their surrounding rural counterparts, presents a critical challenge for urban planners and environmental scientists. This thermal disparity, primarily caused by the replacement of natural landscapes with heat-absorbing surfaces like asphalt and concrete, exacerbates energy consumption for cooling, contributes to air pollution, and poses health risks during heatwaves. In response, a suite of mitigation strategies has been proposed, with vegetated or 'green' roofs emerging as a particularly popular solution. While their capacity to cool the buildings they sit upon is well-documented, a more advanced and pressing question concerns their collective influence on the wider urban microclimate, specifically their role in cooling entire dense city districts. B. The pri...
