Investigating Climate Impacts of Urbanization and the Potential for Cool Roofs to Mitigate the Kansas City Metropolitan Area’s Urban Heat Island Effect
An urban heat island (UHI) is a phenomenon where the temperatures within cities are greater than those of surrounding rural areas due to human activity and physical properties of urban surfaces. This effect can cause the annual mean temperature within cities to be up to 3oC more than its …

Role of pavements in urban energetics
The Urban Heat Island (UHI) is a sustained increase in temperature in urban areas as compared to adjacent rural areas. This effect is partially due to the replacement of vegetated surfaces with lower-albedo impervious surfaces (primarily made of asphalt and concrete) to make way for urban …

Palm oil shell aggregate as cool pavement by replacing fine aggregate
Urban Heat Island (UHI) phenomenon is due to ever increasing environment temperature in cities compared to the adjacent non-urbanized areas. One of the major contributors to UHI is asphalt pavement because of its tendency to absorb high amount of heat due to its dark color. Cool pavement is known …
