Eco-Friendly Landscaping

Plant Trees

Everyone knows that trees are green, absorbing carbon dioxide and releasing oxygen.

Planting a few strategically planted trees can help to cool off a building and reduce the amount of energy allocated to air conditioning.

Planting deciduous trees (trees that drop their leaves in the fall) is a great way to cool your home and reduce your air conditioning costs during the summer. When these trees drop their leaves, they also allow sunlight to warm a home or building during the winter. To maximize the benefits of deciduous trees, plant tall trees on the east and west-facing sides of your house.

This will help shade your home during the hottest months of the summer. Planting trees on the south facing side of your home can help shade the roof, as the sun will not hit that side of the house much during the summer. Make sure to prune trees so that at least a few branches are shading the roof and the air conditioning unit. This adds up to additional energy savings.

Evergreen trees are very useful if you want to create a natural windbreak to reduce those chilly winds that hit your home during the winter. It’s common to plant trees for windbreaks on the north and west sides of a home. However, you will need to determine the dominant wind direction for your area and plant upwind.

Trees should also be planted to shade paved areas. Light energy striking dark pavement like asphalt is absorbed, causing the air above to be heated. Light colored pavement absorbs less energy, but can reflect it toward a building. Tree leaves reduce heat and reflection as they absorb light energy and use it to evaporate water.

Shrubs and ground covers can also help improve the energy-efficiency of your landscape as well. Planting shrubs, bushes, and vines next to your home creates a dead air space that insulates your home both winter and summer. Groundcover plants will shade the soil and pavement around your home, reducing radiation and cooling air before it reaches your home.
