Influence of Tree Canopy Coverage and Leaf Area Density on Urban Heat Island Mitigation

Urban heat islands (UHI) are a widely documented phenomenon that adversely increases urban overheating and, among other effects, contributes to heat-related mortalities and morbidities in areas. Consequently, comprehensive UHI-mitigating measures essential for improving microclimate environments contributing salutogenic design practices. This study proposed cooling strategies involving different tree percentages leaf area densities dense during the summertime Korea. The effects of sixteen various combinations scenarios based on common types were studied via in-situ field measurements numerical modeling, considering both vegetated exposed It was observed by changing characteristics density (LAD) per plant our base area—for instance, from 4% trees 60% trees, low LAD high LAD—the daily average maximum temperatures reduced approximately 3 °C 5.23 °C, respectively. obtained results demonstrate usefulness mitigate heating, they particularly useful designers policymakers their efforts minimize UHI effects.
