“…The direct link between the air temperature and the surface translates the mentioned signal to the temperature of screen level (Heusinkveld et al, 2010;Steeneveld et al, 2014). A lot of prior studies focused on the lakes role on the urban microclimate (Givoni et al, 2003;Olah, 2012) concentrated on UHI of daytime and thermal human comfort. Although this matter covers a restricted view upon the problem, as the UHI is in its largest amount around sunset.…”

In urban areas, water bodies have a positive effect upon microclimate of the surroundings with the relative cooling impact it has on evaporative procedure. Hence, evaporative cooling might be one of the pretty efficient methods of passive cooling for urban spaces and buildings. Differences in temperature between the urban space and the non-urban space which surrounds, is dubbed UHI (Urban Heat Island) effect. Water bodies have also been proven to be influential methods of decreasing urban temperatures. A water body temperature is capable of being lower than the surrounding urban environment around 2 -6 °C. According to these findings; one may conclude that the rise of evapotranspiration in cities, that has roots in vegetation and water body, can efficiently mitigate the influence of the urban heat island. Unfortunately, the effect that water bodies can have upon urban temperatures has not been thoroughly assessed in previous studies, specifically the difference between the daytime and night time influences of water bodies, and the matter the how urban design may be in influential in moving the cooling influence from the water bodies toward the city. This paper provides a theoretical background for the problem and reviews the related literature.

“…However, many recreational activities of considerable commercial value are conducted outdoors (e.g., sporting events, theme parks, cultural events, etc…) and an increasing number of weather sensitive businesses in the service sector, such as restaurants and cafes, are taking advantage of outdoor environments [24]. It should be also considered that outdoor thermal comfort is one of the main factors affecting the habitability of a space and the quantity and frequency of activities depend on the quality of the microclimatic conditions [25]. This is why urban areas must be planned by implementing, where necessary, proper mitigation strategies.…”

Evaluation of Different Urban Microclimate Mitigation Strategies through a PMV Analysis

et al. 2015

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.

“…High local temperatures are related to high gains (earnings) and heat emissions from urban pavements, having a causal relation with the insolation [51,52] evaluated by the SVF. The SVF has a low correlation with the air temperature (microclimate), but strong correlation with the surface temperature and consequently with the phenomenon of HI's, allowing identifying places with high insolation features and a consequent low appropriation [53,54] (Table 1).…”

Abstract:The article presents a case study about thermal comfort in two public squares located in the coastal region of southeastern Brazil, within a post-occupational assessment context where it was sought to estimate the thermal sensation and perception of the users generating systematized knowledge about the built environment. The objective is to instruct future interventions for improvement in the living condition where it is particularly important for the success of the activities predicted there. Surveys on thermal comfort along with goers of the squares were held on three consecutive days in April 2013 and February 2014 with microclimate monitoring of the places adopting the predictive PET (physiological equivalent temperature) index calculated based on the bioclimatic model Rayman. The obtained data set generated valuable information about the pattern of thermal comfort allowing understanding the analytical correlations between PET index, climate variables and the perception of comfort. The article seeks to contribute towards the recognition of bioclimatic specificities in the project process aimed to the improvement of the environmental and social performance of public squares and aspects that are relevant to the urban planners.
