Commercial Status Implementation Issues Sustainable Sources 1994-2000. Well developed but under-utilized. Available, but generally not practiced. The costs associated with implementing a landscape design that is energy conserving should not impact costs more than conventional landscapes. A landscape that is energy conserving is very appealing particularly since aesthetic enhancements are integral to any planned landscape design.
Trees can have a canopy large enough to shade roofs, reducing cooling costs and increasing comfort.
The best locations for deciduous trees are on the south and east sides of a house. When these trees drop their leaves in the winter, sunlight can reach the house to help in heating the home. Evergreen trees on the north and west sides afford the best protection from the setting summer sun and cold winter winds. If large trees need to be planted, it is best to select trees that have a moderate growth rate rather than fast growing varieties. Moderate growing varieties are sturdier against storm damage and generally more resistant to insects and disease.
