Landscaping to save energy
Thoughtful planning, good design and proper planting when landscaping around your home can result in year-round energy savings.
Correctly positioned trees can save up to 25% of a typical household’s energy use, according to the United States Department of Energy. Research what trees and plants are best for your local climate.
Strategically placed deciduous trees allow for summer shade and passive solar heat gain in the winter when leaves have fallen, leading to energy savings in both seasons.
Choose varieties of trees that are known to have a strong root system as well as strong branching angles. An overall strong structure and regular tree maintenance can help reduce the potential for damage from wind, heavy snow or ice.
Plant large trees far enough away from your home to prevent damage from falling branches or root damage to your home’s foundation.
Smaller plantings closer to the home can 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.
Wind protection
Windbreaks are another landscaping strategy that can be beneficial for energy savings in windy areas. The U.S. DOE says windbreaks reduce wind speed by as much as 30 times the windbreak’s height. That, in turn, reduces wind chill near your home and can lower heating costs. The agency recommends planting two to five times the mature tree’s height away from your home.
Plant evergreen trees and shrubs for windbreaks and consider adding fences to help lift the wind up and over your home.
