Shade trees: how smart landscaping helps cool a home

Shade trees savings are slow to start and long to last. The US Department of Energy says smart landscaping can reduce your energy needs and save money on heating and cooling.

Cooler air

Air directly under trees can be as much as 25 degrees Fahrenheit cooler than air above a nearby blacktop parking lot, according to the Department of Energy.

A happier air conditioner

Shading an air conditioner can increase its efficiency by as much as 10 percent, the Department of Energy says.

Planning the shade

Trees that lose their leaves in fall can block summer heat and still let in winter sun. Plant with care so trees do not crowd your foundation or roof.

The fine print

Trees take years to grow, and the Department of Energy gives no single dollar savings figure for shade.

Why it matters

Trees cool homes, clean air and make neighborhoods nicer. It is a long game worth playing.
