Planting windbreaks is a great way to reduce wind speed. A variety of vegetation— such as shrubs, grasses, and trees—can be used to plant these barriers that can help keep your home warmer in the winter and heating costs down.


For best protection, plan on leaving between two to five times the mature height of the trees or shrubs between the windbreak and the protected home.





When shopping for trees, keep in mind the mature height of the tree and the shape of its shade canopy in relation to the height of your home. This will help you determine where to plant. Always avoid planting near underground utility lines or beneath overhead lines.


• Make Your Yard Work For You


BYJOHNDRAKE COOPERATIVE ENERGY ADVISOR


L


ocation, location, location is the mantra in real estate, but it also applies to your yard when you’re looking for ways to lower home energy costs. Placing the right tree or shrub in the right place can yield shade, improve the look of your home and produce welcome energy savings.


The U.S. Department of Energy (DOE), claims smart landscaping can, on average, provide enough energy savings to see a return on your investment in less than eight years.


Again, think location. Using computer models, the DOE determined that proper placement of only three trees on your property can save an


average household between $100 and $250 in yearly energy costs.


Now is the time to make your yard work for you. A few trees and shrubs can make a big difference in your home’s comfort and in the efficiency of your heating and cooling system:


Use trees and plants to shade a window air conditioner and increase its efficiency by as much as 10 percent. For good airflow and access, position plants more than three feet from your AC.


• • Shrubs and trees can form


windbreaks that keep wind chill away from your home and lower heating costs. Evergreens, especially when combined with a wall or fence , can deflect or even lift wind over a home.


ENERGY EFFICIENCY Tip of the Month


A well-designed landscape provides both energy efficiency and curb appeal for your home. The type of vegetation you choose is as important as where they are planted. Sunlight streaming through windows and bearing down on the roof can drive up air conditioner use. Using shade trees and shrubs in your landscaping plan can help reduce cooling costs. In the winter, deciduous trees lose their leaves and let in warmth.

Shading takes time—a 6-foot to 8-foot tree planted near a house will begin shading windows in a year. Depending on the tree and the home, the tree will shade the roof in five to 10 years.

Make planting shade trees due west of your home’s west-facing windows your first priority.


Select a tree that can be planted within 20 feet of the window and that will grow at least 10 feet taller than that window. If you have the space, use as many trees as needed to create a continuous row along all major west-and east-facing windows.


Contrary to intuition, the least energy efficient place for a tree is to the south of a house.





Remember that different trees can serve a variety of purposes. To block summer heat while letting sun filter through in the winter months, use trees that lose their leaves in the winter. Evergreens and shrubs, on the other hand, are ideal for providing continuous shade and blocking heavy winds. Keep in mind that not all shade plants are tall. Low growing shrubs and groundcover plants also help by reducing heat radiation and cooling air before it reaches your home’s walls and windows.
