One main characteristics of the recent research has been to evaluate the summertime effects of UHI on energy use, air pollution, outdoor ambient temperature, and citizen health. The second aspect of the recent research has been the development and evaluation of materials to counter the effects of summertime UHI. This paper provides a selective representation (by topic) review of the research on the development and evaluation of mitigation measures, including: cool roofs, cool pavements, and urban vegetation.http://creativecommons.org/licenses/by/4.0/Energy and Buildings133834-842 Akbari Hashem Kolokotsa Dionysia Κολοκοτσα Διονυσια Elsevier Cool pavements Cool roofs Urban Heat Island Urban vegetation
