A study in South Dakota found that windbreaks to the north, west,
and east of houses cut fuel consumption by an average of 40%. If
you live in a windy climate, your well designed landscape can diminish
heating bills by approximately one-third.
An unprotected home loses much more heat on a cold, windy day
than on an equally cold, still day. Accuratelyselected landscaping
ideas and well designed landscaping can provide an excellent wind
protection during the
winter. It will inevitably reduce heating costs. Furthermore, these
benefits will increase as the trees and shrubs mature.
The house protected by a windbreak used 23 percent less fuel. In
1 month, an exposed, electrically heated house in South Dakota used
443 kilowatt-hours to maintain an inside temperature of 70 degrees
F. An identical house sheltered by a windbreak used only 270 kilowatt-hours.
The difference in average energy requirements for the whole winter
was 34 percent.
Herere some quick money saving landscaping ideas:
- The best windbreaks block wind close to the ground by using
trees and shrubs that have low crowns. Evergreen trees and shrubs
planted to the north and northwest of the home are the most widespread
type of windbreak.
- Evergreen trees combined with a wall, fence, or earth berm
(natural or man-made walls or raised areas of soil) can deflect
or lift the wind over the home.
- Do not plant evergreens too close to your home's south side
if you are counting on warmth from the winter sun.
- For maximum protection, plant your windbreak at a distance from
your home of two to five times the full-size height of the trees.
- Plant so there will be at least 1 foot (30 centimeters) of space
between full-grown plants and your homes wall.
Of course, the amount of money saved by a windbreak will vary depending
on the climate of the area, location of the home, and the construction
material and quality. A well-weatherized house with adequate ventilation
won't benefit from windbreaks as much as a poorly weatherized house.
