Planting trees in the right locations around your home can improve energy efficiency, reduce cooling costs, and increase overall comfort. By understanding how sunlight interacts with your home throughout the day and across seasons, you can use trees to provide shade where it’s needed most.
Why tree placement matters
Strategically planted trees can improve a home’s energy efficiency by providing shade during the hottest parts of the day and reducing heat gain around the house. Placement—especially in relation to the north, south, east, and west sides of a home—is just as important as the type of tree you choose.
Best trees for shade
Tall, deciduous shade trees are ideal for energy-saving purposes. These trees provide strong shade in warmer months and, because they lose their leaves seasonally, allow more sunlight through when temperatures are cooler. They are especially effective when planted on the west and south sides of a home.
Where to plant for the greatest energy savings
Trees planted on the west and south sides of a home provide the greatest energy savings, as these areas receive the most intense afternoon and summer sunlight. The east side can also benefit from trees that provide morning shade, while the north side typically requires less shading but may still benefit from wind protection or strategic planting.
Seasonal benefits
In summer, trees on the west and south sides help reduce direct sun exposure and keep homes cooler during peak heat. In winter, deciduous trees on the south side allow sunlight to reach the home after leaves have dropped, while the north side remains more shaded and cooler year-round.
Quick planting tips
When planning for energy efficiency:
- Choose tall, deciduous shade trees
- Prioritize planting on the west side to block afternoon sun
- Add trees to the south side for additional summer shade
- Consider the east side for softer morning sun control
- Plan for both summer shade and winter sunlight
