“The net cooling effect of a young, healthy tree is equivalent to 10 room-size air conditioners operating 20 hours a day.” -U.S. Department of Agriculture
“Trees properly placed around buildings can reduce air conditioning needs by 30 percent and can save 20% to 50% in energy used for heating.” – U.S. Forest Service
