Quantifying the energy impact of heat mitigation technologies at the urban scale

 Advanced urban heat mitigation technologies that involve the use of super-cool materials combined with properly designed green infrastructure lower urban ambient and land surface temperatures and reduce cooling consumption at the city scale. Here we present the results of a large-scale heat mitigation project in Riyadh, Saudi Arabia. Daytime radiative coolers, as well as cool materials combined with irrigated or non-irrigated greenery, were used to design eight holistic heat mitigation scenarios. We assess the climatic impact of the scenarios as well as the corresponding energy benefits of 3,323 urban buildings.
