Street Tree Planting Patterns to Modify the Sky View Factor for Outdoor Thermal Comfort Enhancement

Outdoor thermal conditions influence the quality of life in urban commons. Urban vegetation is an effective way to improve pedestrian comfort tropics as it provides shade, reduces surface heating, improves air quality, and human health. The primary objective this study understand correlation between Sky View Factor (SVF) modifications Outdoor Thermal Comfort (OTC) that could inform optimum street tree planting strategies warm, humid, context Colombo, Sri Lanka. Common patterns are identified simulated, utilising RayMan software. Results showed there a distinct advantage trees for SVF thereby increasing OTC. Tree with less yielded better results during day, yet, little or no impact night. Conclusions discuss SVF-based design implications different canyon geometries, orientations explored study.
