Green Roof Impact Heat Islands

Green roofs provide shade remove heat from the air and reduce temperatures of the roof surface and surrounding air.

Green roof impact heat islands.

Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect particularly during the day. Researchers attributed this to the increasing issue of urban heat islands which in turn increased the severity of heat waves in city areas. The report is a reminder that avoiding the worst effects of climate change must go beyond reducing emissions to adapting to changing weather. Green roofs combat the urban heat island effect through three fundamental functions.

Natural greenery in the cities was replaced by concrete yards. A green roof or rooftop garden is a vegetative layer grown on a rooftop. Green roofs and the urban heat island effect green roofs like other green spaces in cities can have a positive effect on the uhie. Green roofs repainting dark surfaces and increased tree planting can all help lower temperatures in summer months.

Smart surfaces have also been shown to make infrastructure cooler and more resilient. This evapotranspiration cools the air around the building. Trees green roofs and vegetation can help reduce urban heat island effects by shading building surfaces deflecting radiation from the sun and releasing moisture into the atmosphere. Plants and soils evaporate moisture.
