Deciduous trees are recommended for planting on the south side of buildings primarily because they provide summer shade while allowing sunlight to penetrate during the winter months after their leaves fall. This seasonal shedding of leaves maximizes energy efficiency; during summer, the broad canopies of deciduous trees block direct sunlight, which helps keep buildings cooler and reduces air conditioning costs. In winter, when the trees are bare, sunlight can reach the building, aiding in natural heating and reducing energy usage for heating systems.

This combination of benefits makes deciduous trees an ideal choice for strategic placement around buildings, especially in climates where seasonal temperature variations are significant. Their ability to provide both shade and sunlight based on the time of year aligns perfectly with energy conservation goals in building design and landscaping.
