The effect of shade trees on summertime electricity use in Sacramento, California



Geoffrey Donovan, David Butry, Joshua D. Kneifel


Although previous studies have shown that shade trees can reduce summertime electricity use, none have compared these reductions to other common energy-conservation measures. We demonstrate that a 30-year old tree planted on the west side of a house in Sacramento, California reduces summertime electricity use by 18%, which exceeds the savings from replacing the house s HVAC system, replacing windows, adding attic insulation or turning the thermostat up by one degree Celsius.
