TL;DR: In this paper, the authors present the actual state of the art on the development and the assessment of cool materials (i.e., materials with high solar reflectance and infrared emittance) for buildings and urban structures.

TL;DR: In this article, the authors report the development and comparative testing of thermochromic coating to be used in buildings and urban structures and demonstrate that the use of thermophromic coatings can both contribute to energy savings in buildings, providing a thermally comfortable indoor environment, while can contribute highly to improve the urban microclimate.

TL;DR: In this paper, the spectral properties and thermal performance of five color thin layer asphalt samples in comparison to a sample of conventional black asphalt were analyzed. And the results of a study aiming to measure and analyze the solar spectral properties was presented.

TL;DR: In this paper, the performance of organic PCMs used as latent heat storage materials, when incorporated in coatings for buildings and urban fabric, is investigated, and the results demonstrate that all PCM coatings present lower surface temperatures than infrared reflective and common coatings.

TL;DR: In this paper, high-spatial resolution multispectral satellite images collected over the metropolitan Athens area in Greece were used to generate (a) a shortwave albedo map depicting the spatial variations across the metropolitan area, (b) a fractional vegetation cover map showing the spatial distribution of urban vegetation and (c) a daytime and night-time land surface temperature (LST) map depicting spatial variations of the surface temperature across the city.
