Q: How can landscaping help lower my energy bill?
A: There’s a lot going on in the space around our homes. Competing factors of aesthetics, safety, energy efficiency, water conservation, and more are a lot to consider. Thoughtful planning and good design can address these factors.
Carefully positioned trees can save up to 25% of a typical household’s energy use, according to the United States Department of Energy. When selecting trees and other foliage, research what is best for your elevation and climate. Select native species naturally adapted to your location for lower maintenance.
Strategically placed deciduous trees allow for summer shade and passive solar heat gain in the winter when leaves have fallen. Slower-growing trees might take longer to provide maximum shading benefits, but their roots are typically deeper, and branches are stronger. These factors can also make them less likely to be damaged by wind, snow, or ice and be more drought resistant.
Plant large trees far enough away from your home to prevent damage from falling branches or root damage to your home’s foundation. And if you have a rooftop photovoltaic solar system, even a small amount of shade can significantly reduce energy production. Consider smaller plantings closer to the home to shade walls, windows, or hardscaped surfaces, such as driveways and sidewalks.
Keep landscaping clear of dryer vents, heat pumps, and air conditioning units to ensure access for maintenance and airflow around those locations.
When landscaping, always consider safety first. Call before you dig to ensure you know where any underground utility and sewer lines are located. The national 811 Underground Service Alert program routes you directly to your local resources. Call 811 or visit call811.com before you dig.
Be mindful of overhead power lines too. Look up and check the surroundings before setting up ladders. Be thoughtful when planting new landscaping that could encroach on power lines. Utility equipment should have at least 10 feet of clearance, when possible.
As you prepare to refresh your yard for the coming spring and summer, consider ways you can boost your energy efficiency for more comfort and savings year-round.
