It has been proposed that as a result of a decrease in temperature, the modification of an urban surface to include more vegetative cover and lighter, lower albedo surfaces would also reduce ozone exceedances, energy consumption, and detrimental environmental and human health effects associated with high levels of ozone. Chicago is among the cities classified as a severe ozone nonattainment area, and is the focus of this study. The purpose of this investigation is to characterize the ozone and temperature relationship in the Chicago area, review strategies that diminish ambient urban temperatures, with particular attention to comparing the total costs associated with asphalt and concrete pavement design, and present the results of an urban fabric analysis for Chicago that reveals areas and land uses where cooling strategies may have the greatest impact.
