“…The various daytime effects reported by others were found in the present study, which may provide a more comprehensive picture since, in addition to climatic measurements, type of vegetation was one of the variables investigated, and the experiment included varied types of vegetation cover. The present study found that irrigated garden trees caused slight daytime cooling (2 1C), similar to results of Sebba and Enis (1984) and Becker et al (2003), while the grove of un-irrigated native desert trees had a slight daytime warming effect, similar to the midday warming of the 'oasis' reported by Saaroni et al (2004).…”

“…The daytime 'oasis effect' has been reported (Becker et al, 2003;Sebba and Enis, 1984). In these cases, the effect was small (o3 1C), similar to the mild daytime cooling effect of irrigated garden trees found in this study, although in their studies, type of vegetation (trees) was not a variable that was investigated.…”

“…For these reasons, the PMV is one of the most widely used indexes to evaluate outdoor thermal comfort [59]. Becker et al [60] evaluated the correlation of observed and calculated thermal sensation values according to this index for four different locations in the area of Kibbutz Yotvata (Israel) and they found that the correlation coefficient ranged between 0.60 and 0.81 with an average of 0.70. Similar results were obtained by Bouden and Ghrab [61]: they carried out a cross-sectional investigation in five different Tunisian cities finding a correlation coefficient of about 0.71.…”

Abstract:Outdoor thermal comfort affects the health of the people and the quality of life in urban areas. This is the reason why in the past few years different mitigation strategies for the microclimate have been studied and examined. These strategies depend on those passive factors characterizing the urban setting that are able to affect the values of local meteorological variables, as the limit surfaces of the urban space (parterre and façades of the buildings). This paper examines the Cloister by Giuliano da Sangallo, which is part of the Faculty of Engineering of Sapienza University of Rome. The case study compares the present configuration of the Cloister with four other configurations characterized by some vegetation and materials with a high albedo by taking into consideration the PMV (Predicted Mean Vote) model. Microclimatic variables are calculated through numerical simulations performed by the ENVI-met software. Such a comparison is performed during a typical summer day. While examining the results it can be noticed how the strategy presenting the best results is the one with some vegetation, whereas the materials with a high albedo improve the microclimate if applied on surfaces characterized by a high sky view factor.

“…Human discomfort can be evaluated through a number of theoretical and empirical biometeorological indices requiring usually a larger or smaller number of input parameters such as air temperature, wind speed, air humidity etc. (Becker et al 2003;Conti et al 2005;Höppe 1999; Matzarakis et al 2000;Nastos and Matzarakis 2006).…”

The paper studies the climatology of the Discomfort Index (DI) and the Common Air Quality Index (CAQI) in a large Mediterranean urban center (Greater Thessaloniki Area), examines the relations between the indices and the climatic conditions in the study area and investigates the linkage between the Urban Heat Island (UHI) effect and the enhanced discomfort and poor air quality in the city center. Discomfort conditions are more enhanced during July and August. Atmospheric conditions when the population suffers discomfort and feels severe stress are found mainly in the summer season hours with total frequency that can be up to about 4% in a month. Throughout the year, air quality conditions are unhealthier in the stations of urban characterization. Very high daily CAQI values are more frequent during the cold period (about 14%) than during the warm period (1-2%) of the year in the urban stations. Daily DI≥24°C could be more associated to increased temperature than relative humidity and is strongly related to high and very high CAQI values. During summer, when daily CAQI is ≥76, the feeling of discomfort is the most probable. Consequently, a strong synergy between discomfort and bad air quality exists in summertime. High and very high CAQI values and the discomfort feeling by the majority of the population are related to stagnant atmospheric conditions. During summer season, the poor air quality and the unfavorable comfort conditions for the majority of the population in the city center are associated with the greater frequency of a more intense UHI effect. The above phenomenon is more pronounced during nighttime than daytime.
