McConnell, K., E. Glenn, N. Stamler, R. Pandya, J. Abramowitz, G. Fernandez, and C. Braneon, 2020: Not all green roofs are alike: Variation in heat mitigation capacity among green roofs in Chicago. Landsc. Urban Plan., submitted.

In the coming decades, millions of urban residents will be exposed to potentially deadly heat extremes. In attempt to respond to rising temperatures, many cities have begun to implement green roofs, which now vary widely in structure and size, and have generally been shown to have cooling capacity. Yet, little research has been done to differentiate which types of green roofs are most effective at reducing urban heat, which is critical information for policymakers and planners as they make decisions around optimum green infrastructure for their cities. We utilize 60 satellite images taken from Landsat 5 TM during the summers between 1989 and 2011 to model land surface temperature (LST) and normalized difference vegetation index (NDVI) for three green roof sites across the City of Chicago: Millennium Park, Chicago City Hall's rooftop, and a Walmart Supercenter. Leveraging a quasi-experimental research design that has been little-used in green infrastructure research, we evaluate the heat-reduction performance of each green roof relative to a nearby non-green roof. Each site examined shows distinct effects on land surface temperature, suggesting that larger, intensive green roofs with diverse plant species have greater heat mitigation capacity in temperate regions than extensive, monoculture green roofs. Only one out of three green roof sites examined lowered absolute land surface temperature, suggesting that many green roof types may only limit the rate of warming, rather than actively cooling.
