Effects of Street Tree Configuration on Urban Heat Island Mitigation
Urban Heat Island is increasingly affecting cities in developing countries with rapid urbanization. Uncomfortable thermal environments are present in the urban streets of tropical towns due to the need for more urban vegetation. A well-planned street tree configuration can positively influence the thermal environment within metropolitan regions. This study intends to explore the tree configuration impacts on the roadside thermal environment in urban canyons of selected sites in Colombo, Sri Lanka. Field data was collected to identify street canyons’ heat patterns considering existing roadside greenery configurations. Suitable tree-planting scenarios to regulate the microclimatic conditions were also investigated. Three different roadside tree configurations in Colombo and its suburbs were considered. Climate data, tree, and surrounding attribute data were measured. The 3D microclimate simulation software ENVI-met Lite version was used to identify heat distribution patterns and carry out scenario simulations. The results indicated that the heat distribution in the roadside area is reduced when the tree configuration of continuous tree rows with densely foliated vegetation is applied.
