Shelter your house from winds that cool it in winter and warm it in summer
A windbreak on the north or west sides of a house can reduce the chilling effect of cold winter winds. Similarly, planting windbreaks on the south and west sides of a house can help deflect hot summer winds that tend to pull cooler conditionedair from the inside. Evergreen trees and tall shrubs planted close together make the best windbreaks, but even vines grown on trellises help to deflect wind around windows, which are the most poorly insulated parts of a house.
Shade windows and walls from the summer sun
Trees planted to shade the southern and western windows are effective barriers to light in the hot summer sun. Using deciduous will block the sun when it is not desired and allow it to pass through to the home in the winter when the energy is desired. Not only to trees block direct sunlight, but water evaporating from trees helps cool surrounding air.
According to the U.S. Department of Energy, trees that shade the south and southwest sides of a house can cut between $100 and $250 annually from air-conditioning costs. If your property is unshaded, planting the right trees in the right places offers long-term benefits. The height, growth rate, regional adaptability, branch spread, and shape of different tree varieties are all factors to consider in choosing the most beneficial trees.
Keep cool with a well maintained lawn
A healthy front lawn has the same cooling effect as an 8-1/2 ton air-conditioning compressor according to a Mississippi State University study. The plants transpire, or evaporate water through the leaves surface, to cool themselves. In addition to cooling themselves off, the keep the immediate area cool as well. About half of the heat energy directed to a turf area is eliminated by transpiration.
"When the temperature of the sidewalk is 100 degrees Fahrenheit, the temperature of the adjacent lawn remains near 75. This cooling may last into the night, with studies showing a 13-degree cooling at 9 p.m." scientists say.
