Landscaping - Windbreaks
Strategically landscaping a home to create and provide windbreaks can have a significant effect in lowering winter heating costs. The idea is to block or reduce the speed of wind that reaches your home.
Dense evergreen trees and shrubs planted to the north and northwest of your home are the most common types of windbreak, using low-crowned trees and shrubs to effectively block wind at ground level. Evergreen trees combined with a wall, fence or earth berm can do more than block cold air; they can completely lift frigid wind over a home.
Additionally, shrubs, bushes and vines planted next to a home insulate it in winter and summer.
