“…In addition, vegetation as a microclimatic optimizer works perfectly in conjunction with trees in contrast to being implemented solely. This statement is verified by many studies which mainly concentrate on the importance as well as the effects of vegetation on regulating Tmrt and PET (Ali- (Lee, Holst, & Mayer, 2013) (Hisarligil, 2013) (Makaremi, Salleh, Jaafar, & Ghaffarian Hoseini, 2012) (Yahia & Johansson, 2014) (Shashua-Bar, Pearlmutter, & Erell, 2009) (Robitu, Musy, Inard, & Groleau, 2006) (Christopoulou, Tsiros, Hoffman, & Tseliou, 2015) (Chen & Ng, 2013) (Lin, Matzarakis, & Hwang, 2010) [61-70]. Taleghani's et al ) study which is conducted in a temperate climate discusses different approaches for decreasing absorbed solar radiation such as geometrical parameters (orientation and overall configuration), vegetation, using surfaces with higher albedo and water pools.…”

The growing interest in thermal comfort of outdoor environments yields in different analysis on courtyards as a common space between urban and architectural scales. However, there is a limited knowledge regarding the microclimatic behavior of such spaces. Using ENVI-met simulations, this paper aims to numerically discuss the thermal performance of different configurations of traditionally designed courtyards in Shiraz, Iran, which experiences hot summers and cold winters. The geometrical effects such as orientation and H/W (height to width ratio) of courtyards are considered as potential parameters to improve the microclimatic conditions. In this paper, PMV and UTCI are used as thermal comfort indices.The obtained results indicate mean radiant temperature and wind speed as the most effective parameters for thermal comfort of courtyards. In addition, the aforementioned geometrical parameters might not be able to solely create a desirable condition, but they could significantly improve the thermal comfort of courtyards during summer and winter. To achieve a desirable thermal comfort level, the results suggest using configurations of a high H/W rate and southward orientation in order to obtain better shading during summer as well as allowing the solar radiation in while regulating the wind speed in winter.

“…These studies explained the consequences, implication and outcomes of how heat stress affected human life. Moreover, some studies confirmed the importance of shaded areas when designing outdoor spaces (Hwang et al, 2010;Makaremi et al, 2012). Previous studies also confirmed that people adapted to varying outdoor conditions through behavioural and postural changes, acclimatization and their perception of the outdoor conditions (de Dear & Brager, 2001;de Dear & Brager, 1998).…”

This paper clarifies the perceptive and adaptive mechanisms involved in an outdoor thermal comfort in hot, and humid condition. The method of the study was through microclimate measurement coupled with structured interviews of urban park users. The objective of this study is to identify the impacts of weather and personal factors on respondents' perceptual and sensation estimations. The findings on the significant influences of microclimate parameters and personal factors on the participants' perceptions of outdoor urban places are discussed. This study shows the respondents' thermal adaptation from physiological and psychological perspectives. The significance of the findings showed the importance of a sustainable urban park for continued use by future communities.

“…These indices, e.g., the physiologically equivalent temperature (PET), the predicted mean vote (PMV), the standard effective temperature (SET), or the Universal Thermal Climate Index (UTCI) take into account the combined effects of air temperature, radiation, humidity, and wind speed on human thermal sensation [44][45][46][47][48]. In order to assess outdoor thermal perception, these indices, which are based on meteorological measurements, are often accompanied by questionnaires that account for non-physical factors, such as psychological parameters [45,48]. In many cases, field studies are complemented by numerical simulations conducted with micro-meteorological models, such as the ENVI-MET model [49].…”

This review paper focuses on research schemes regarding urbanity and urbanization, and brings together both cultural and physical approaches. First, we review the cultural and social construction of urbanity (as related to urbanization) in Germany. In the early 20th century, urbanity was mainly the result of identity derived from a historical perspective in cities. This has changed profoundly in recent decades as urbanity stems more and more from various urban lifestyles and the staging of societal experiences, as summarized in the German term, "Erlebnisgesellschaft" (thrill-seeking society). The discussion is extended by an assessment of the recent state of the art regarding physical urban research. The focus lies on different fields of research; we address topics such as biodiversity, urban climate, air pollution, and resilience, as well as their impact on urban planning and governance. In conclusion, in order to tackle recent developments and future challenges regarding social and environmental issues, an integrative approach urges novel cross-and inter-disciplinary research efforts in urban studies, including urban-rural linkages. A newly constituted assessment of urbanization and city quarter development is proposed; the assessment focuses on the conjoint analysis of mobility, "Energiewende" (energy transition), cultural drivers, demographic development, and environmental issues.
