Hygrothermal performance of cool roofs with reflective coating material subjected to hot, humid and dusty climate

Abstract: The measurements for the short-wave solar reflectivity of a Reflective Coating Material (RCM) with various cleaning operations that were obtained in a previous study were used in this study to conduct numerical simulations in order to assess the moisture and energy performance of cool and black roofs when they were subjected to the weather conditions of Saudi Eastern Province and Kuwait City. The results of the numerical simulations showed that black roofs always work with less moisture than cool roofs. Becaus… Show more

“…Currently, there are five strategies that can be applied in order to mitigate the effects of urban heat islands [7][8][9][10][11][12][13]). These strategies include increasing vegetation and trees in urban areas [8], installing reflective pavements on streets, sidewalks and parking lots [9,10], utilizing smart growth practices that help protect the natural environment [11], installing green roofs by growing vegetative layers on the rooftops [12], and installing cool/white/reflective roofing systems [6,[13][14][15][16][17]. Throughout this paper, unless otherwise specified, cool roofs, white roofs and reflective roofs have the same meaning.…”

“…Generally, the external surfaces of different types of roof systems (traditional, green and cool) are exposed to several environmental factors that include dust/dirt, cloud coverage, sunlight, rain, snow, wind, outdoor temperature and relative humidity. The performance of the roofs depends mainly on these factors and the roof specifications [6,[14][15][16][17]29]. The absorbed solar radiation on the external surfaces of the roofing systems causes an increase in the surface temperature of the roof, thereby increasing the cooling load in summer and reducing the heating load in winter [30].…”
