	===Roof Overhangs===		===Roof Overhangs===
	Roof overhangs are simply portions of a roof that extend out beyond the wall of a home.<ref name="RE1">Architecture . (October 17, 2015). ''Passive Solar Heating and Cooling'' [Online]. Available: http://architecturerevived.blogspot.ca/2013/10/designing-passive-solar-heating-and.html</ref> These are designed with a specific length so that during the summer the overhang blocks the higher [[Sun]] from hitting a portion of the roof during the day. In the winter, the Sun is lower and more of its [[light]] is let through to warm the house.

''Shading'' [Online].

	The ~~height of~~ the Sun in the ~~summer and~~ winter ~~varies with elevation~~, ~~but this method can be used~~ to ~~warm and cool houses many places around~~ the ~~world~~.		Figure 2 shows both the summer and winter sun. The overhang is long enough to shade the Sun during summer but short enough to allow sunlight in during winter. This keeps sunlight out during summer, keeping the internal living space cool. During the winter, the overhang allows [[solar radiation]] to enter the building, warming up the internal living space.

	Figure 2 shows both the summer and winter sun. The overhang is long enough to shade the Sun during summer but short enough to allow sunlight in during winter. This keeps sunlight out during summer, keeping the internal living space cool. The opposite is true in the other half of the year. The overhang allows [[solar radiation]] to enter the building, warming up the internal living space.

	Planting deciduous trees in front of windows that receive a large amount of solar radiation can help to moderate the temperature inside the home.<ref name="RE1"/> In the summer months when the tree has its leaves, the amount of solar radiation into the home is limited. Conversely, in the winter when the tree loses its leaves more Sun is allowed in and the home is warmed.

During summer, shown on the left, the leafy tree prevents excessive amounts of solar radiation from entering the building, keeping the internal living space cool. The opposite is true in the other half of the image, during the winter. A bare tree allows adequate amounts of solar radiation to enter the building, warming up the internal living space.

			Finally, objects inside the home can be used to shade how much solar radiation is allowed to enter the home. Objects inside a room can block or filter sunlight, especially [[water]] elements such as fish tanks. When incident sunlight hits the fish tank the water absorbs some of the [[heat]] and works to keep the room inside cool. Recall, water's high [[specific heat capacity]].

Compared to other methods, these design features are generally simple to implement and fairly inexpensive. As well, the use of shading technology is beneficial as it can help reduce the costs related to heating and cooling of a space, and thus these technologies are considered a part of [[energy efficient building design]].
