Did you know that you can save money from your landscaping? Strategically placed trees can lower your cooling bills by as much as 10%. This is both because of the shade they provide, as well as, the water vapor that trees release into the surrounding air.
Of course, fast growing trees will provide a quicker return on the investment, but those trees are also more prone to insect infestation, as well as, damage due to drought or winds. Slow growing trees will generally live longer.
Planning your landscaping will guarantee a greater effect. Trees planted in the south or west side of your house will give the best energy savings. They need to be fairly close to the house for the shade to cover it well.
The initial cost will be fairly high depending on the type of trees planted, and it will take many years until you see the benefits from this, so it is definitely a long term investment.
