Green Roof Impact Heat Islands

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.

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 roofs and the urban heat island effect green roofs like other green spaces in cities can have a positive effect on the uhie. The first is evapotranspiration which is the process of using heat in the air to evaporate water in plants and soil. The report is a reminder that avoiding the worst effects of climate change must go beyond reducing emissions to adapting to changing weather.

Smart surfaces have also been shown to make infrastructure cooler and more resilient. This evapotranspiration cools the air around the building. A green roof or rooftop garden is a vegetative layer grown on a rooftop. Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect particularly during the day.

Natural greenery in the cities was replaced by concrete yards. Extreme heat events often affect our most vulnerable populations first. Heat island effect in cities is mainly because of non natural heat absorbing materials use in buildings and other manmade structures. Plants and soils evaporate moisture.
