=== Shade with trees===
[[Planting trees]] for the purpose of providing [[shade (shadow)|shade]], which reduces cooling costs. The mature height of the trees and their canopy shape need to be well studied. The locations of the trees should be chosen based on their height and the height of the building. Also, when trees are planted closer to the windows or walls, they will provide shade for a greater portion of the day as the Sun keep changing its relative position to the window and the trees. Planting the trees too close to the building, however, is also not desirable, as it might create the danger of touching above-ground or underground utility lines.<ref name=":0" />

The type of leaves of the trees is also important. Broad-leaf evergreens like Southern magnolia can be used to provide dense year-round shade. However, needle-leaf evergreens like pines and cedars can provide more air circulation though their shade is sparser and more open.<ref name=":0" />

Not only can tree shade be used to reduce the cooling load in building, it can also be used in parking lot, driveways, and playgrounds.<ref name=":1">{{Cite journal|last=Hoeven|first=Gustaaf A. van der|date=November 1982|title=Energy efficient landscaping|url=https://krex.k-state.edu/dspace/handle/2097/21907|language=en}}</ref>
