Studying the effect of “cool” coatings in street urban canyons and its potential as a heat island mitigation technique

Surface temperature measurements were performed in a deep street canyon, during summer period, in the center of Athens. Surface temperature was measured on an hourly basis, at several spots, in the external facades of buildings, pavements and at ground level inside an urban canyon. At the same time experimental data of air temperature were collected through extensive monitoring at four different heights in the center of the urban canyon. Based on these measurements air temperature vertical stratification was analyzed and interpreted as a function of the coating used.
