This study estimated the direct energy savings for homes in relation to tree cover. Specific site differences using actual electric usage for homes were identified. Four sites, ranging between thirty and forty houses per site, were selected at various canopy cover levels (15, 25, 39, and 54%). Tree attributes were measured for each parcel containing a house. Home energy use for cooling months (June-September) was obtained from Allegheny Power, for the years 2005-2008. A difference in tree height and crown area was observed, but these did not correlate with differences in energy use. The percentage of shrubs around the house was found to differ and a weak, but significant, relation was identified between percentage of shrubs and energy usage. Energy usage was lowest when canopy coverage was highest and state urban forest managers should concentrate efforts to increase the urban forest in cities and region that have low canopy coverage.
