Parking Lot Shade

Reference Type
Report (Research or Project)

This is the final report on a study to determine the amount of VOC reduction from parking lot shade (i.e. parked vehicles) in Illinois (US).

"Pilot studies at Davis and Los Angeles, California1, have been performed on parking lot microclimates to measure the impact of shade tree cover. According to the studies, a 50% canopy of tree cover lowers the ambient temperatures for parked vehicles by approximately 4-8 F. The studies present estimations for the volatile organic materials (VOM) reductions that result due to less evaporation from the fuel and fuel systems of the parked vehicles." [Background]

With a 50% canopy cover, the potential reduction is reported at 0.645 to 1.132 lbs VOC per 1,000 vehicles parked per day.

Canopy coverage is 50% at 10 years (from planting) and specified at 1 tree for every 4 parking spaces.
