Trees and other vegetal materials are an integral component in urban or suburban environment, particularly in the residential landscape. In the literature, there are numerous studies on the roles that street trees and/or residential gardens play in shaping neighbourhood character, enhancing property value, mitigating urban heat island effect, and improving carbon sequestration of terrestrial ecosystems. However, these studies are mostly in a general sense and at relatively coarse spatial and temporal scales. In this study, spatially explicit models are developed to simulate the effects of tree phenology and the associated tree canopy dynamics on regulating solar exposure and natural thermal comfort in a typical residential building in Melbourne, Australia. Tree canopy dynamics are investigated and applied to simulate seasonal solar exposure and indoor temperature variations in a parametric environment. The outcomes from this study can be used to guide landscape planting design aiming at not only providing conventional ecosystem services but also reducing household energy consumption for heating and cooling, which will have enormous implications in landscape design in an era of climate change.
