TL;DR: In this paper, the state of the art in terms of local climate change and urban heat island mitigation techniques are presented in detail, in particular developments in the field on highly reflective materials, cool and green roofs, cool pavements, urban green and of other mitigation technologies.

TL;DR: In this article, the angular reflectance of retroreflective (RR) films for several inclination angles of solar radiation was measured in order to quantify cooling potential of RR materials in terms of energy reflected and sent beyond the urban canyon, and the experimental characterization and energy evaluations showed that RR materials could be effectively applied as coatings on urban paving and building envelope, to reduce the circulating energy into the canyon.

TL;DR: In this article, the authors compared the measured and calculated surface temperature for the initial coating and the air temperature in the center of a deep street urban canyon, in order to calculate surface temperature in buildings' facades and at street level as well as air temperature inside the canyon.

TL;DR: In this paper, the impact of the urban heat island to the prevailing environmental and microclimatic conditions, to the needs for energy production and use at the city and neighborhoods, and to the society, especially with respect to the quality of life, the exposure of elderly people to adverse thermal conditions and the capacity of households to adjust are provided and discussed in detail.

TL;DR: In this article, an original method to quantify the urban heat canyon effect as a function of meteorological conditions, geometry, and surface properties is proposed, in order to provide a reliable tool to estimate the effect of the reflective properties of the canyon surfaces on the urban environment.
