Smart Landscaping Slices Energy Bills
Reduce heating, cooling and water costs beautifully with these ecofriendly strategies for landscape design
Effective landscaping can produce environmental benefits in each of the green building categories defined by the U.S. Green Building Council's LEED ranking system: water efficiency, indoor air quality, materials, atmosphere, sustainability and energy. For simple, beautiful landscaping strategies that save energy and money, read on.
Plant conifers where they can serve as a windscreen. They'll block cold winter gusts, provide beautiful green buffer zones and prevent winds from wicking away indoor heat.
While evergreens with dense foliage provide a stronger buffer, these highly structured conifers have an architectural appeal.
For a clean look or for an area where foliage will not thrive, a wall might also provide a similar level of wind protection.
Homes in colder climates can add warmth by placing fire features and outdoor kitchens close to the home, where the heat can permeate or serve as a buffer to colder surrounding temperatures. In this garden, the strategy provides another benefit: The structure of the home and fireplace, along with the roof, could make the outdoor space usable in colder months.
In warmer climates, it may be wise to place fire features and outdoor kitchens at a distance that prevents heat from enveloping or entering a structure during hotter times of the year.

Deciduous trees, unlike many conifers, are fantastic energy savers, providing shade in the summer months while letting in light and heat in winter.
Trees are the ultimate air conditioners. They provide shade and can reduce temperatures underneath by as much as 20 degrees.
This home's striking floor-to-ceiling windows must provide lovely daylight lighting, making it possible to cut down on artificial light. The wall of trees filters the sun, reducing glare and heat.
Of course, trees can provide the same shady benefit to an outdoor garden space.
In the winter, when leaves have fallen, deciduous trees let sunshine through to warm outdoor and indoor spaces, reducing home heating costs.
As you may have guessed, strategic placement of conifers varies from strategic placement of deciduous trees. Deciduous trees work best to the south and west of homes, the areas most likely to receive direct sunlight.

Hardscapes such as concrete drives and patios are known for increasing the "heat island" effect. When sunlight reflects off their hard surfaces, it reverberates, heating an area. Opting for green foliage, even at ground height, keeps a space cool.
A meadow like this, especially as an alternative to a traditional lawn, is a great bang-for-the-buck sustainable landscaping strategy. It produces dramatic improvements in both indoor and outdoor air quality. By reducing the need for energy and water, it can save a family as much as $2,500 per 1,000 square feet each year.

If hardscaping is necessary, it's good to know that light materials attract less heat.
Natural materials, such as this decomposed granite, may also absorb light and heat. Many of these materials are appropriate for driveways as well as patios.
Creating a green wall prevents structures that receive excessive sunshine from transmitting the sun's heat indoors. This wall at Los Angeles' SmoggShoppe is not just energy efficient; it is living, vertical art.
Of course, if that heat is what you desire, this is not the approach for you.

Planting thick foliage in external containers is a simple strategy that requires less technical expertise and commitment than a green wall. When temperatures cool, move the containers to sheltered or indoor spaces.
