“…Wind is a significant factor affecting thermal sensation in urban climates (Sadeghi et al, 2018). Ketterer and Matzarakis (2014) indicate that air temperature alone is not an appropriate measure to quantify the intra-urban spatial variability of climate with respect to human thermal comfort.…”

Wind is one of the main factors affecting people's outdoor thermal sensation. Ongoing urbanization and urban densification are transforming the urban climate and complicating the pedestrian-level wind environment. Therefore, the main aim of this research is to evaluate the potential wind-cooling effect on human outdoor thermal conditions. Accordingly, the current research attempts determine the best wind directions for thermal comfort at the studied stations and how these factors will be changed under the effects of global warming. Outdoor thermal conditions were modeled based on the physiologically equivalent temperature (PET) thermal index using RayMan software for the decades of the 2000s and the 2040s in different climate types of Iran (Csb, BWh, Csa, and BSh) To estimate the potential cooling effect of wind, the PET was calculated (1) under actual wind conditions, and (2) under calm wind (0.05 m/s) conditions. Then, the ΔPET for these two conditions, which indicates the cooling potential effect (CPE) of the wind, was calculated for four representative stations (Ardebil, Bandar Abbas, Gorgan, and Shiraz). In comparison with the 2000s, the results indicated that by the 2040s, the predicted wind cooling potential will have increased in Ardebil, Shiraz, Bandar Abbas and Gorgan (CPE of 13.2 • C, 13.1 • C, 11.2 • C, and 11 • C, respectively). Based on the overall average of two climate change scenarios (A2 and B1) used in this study, the occurrence of "comfortable" conditions by the 2040s will have increased in Bandar Abbas, Shiraz, and Ardebil by 1.1%, 0.4%, and 0.3%, respectively, while it will have decreased in Gorgan by 1.5%. Accounting for the cooling effect of wind, the comfort cooling potential of wind is predicted to rise by an average of 1.6 • C in the 2040s compared with the 2000s in all the studied stations. Therefore, this will affect the microclimates positively and could reduce the urban heat island effects.

“…The result of the comparison showed that the thresholds calculated in this study conform to what previous studies reported. Particularly, these thresholds calculated in this study do not seem to contradict with wind comfort criteria guideline developed for Melbourne CBD before [30]. The guideline that is based on Melbourne Wind Criteria [31] advised that for different postures, V a values should not be greater than 3 m/s for sitting, 4 standing and 5 m/s for walking individuals.…”

“…GWTS [30] has proposed several design options to engineer wind flow for better thermal comfort in Melbourne CBD. Additionally, the adoption of lift-up design for the densely built-up area with high rise buildings is advocated recently by several researchers around the world [11,22,53,54] and this applies to Melbourne's CBD conditions.…”

“…This wind chill factor makes the "real feel" temperature much cooler than the actual meteorological readings. Conversely, this wind is most welcomed during warm seasons when it can lessen the number of hours of thermal discomfort.The research on wind comfort perceptions in Australian capital cities is limited [29][30][31]. Melbourne [31] was a pioneer in the investigation of wind speed on people in Australia which resulted in the development of Melbourne's wind acceptability criteria.…”

Dense urbanization influences the livability of cities. Changes in local meteorological conditions can be adverse for human health and well-being. In urban open spaces, it is widely known that changes in building density and configuration in cities influence wind speed (V a ). This influence modifies latent heat flux between the human body and surrounding environment and thereby affecting the thermal comfort conditions in open spaces between buildings. Several studies have demonstrated the significant effect of wind speed on outdoor thermal comfort. Melbourne's Central Business District (CBD) has recently experienced dense urbanization and this pattern of development has instigated noticeable changes in meteorological conditions. Some evidence has suggested that the patterns of wind flow induce thermal discomfort during cool seasons. Conversely, the wind is most welcomed during warm seasons. This study was conducted to assess outdoor users' responses to V a in three open spaces of an educational precinct in Melbourne's CBD. The open spaces studied are different in terms of design and function. Users' responses and meteorological conditions were examined through a series of field measurements and questionnaire surveys from November 2014 to May 2015. This study used three perceptual scales to analyze participants' experience of V a during field surveys: "Bedford preference", "thermal sensation" and "personal acceptability". Analytical results yielded the wind perceptual comfort thresholds for different seasons as well as the entire study period. The results suggested that in addition to the geometry of the urban open space, the function of place could influence people's perceptions of V a . The research findings contribute to developing thermally comfortable outdoor environments.Climate 2019, 7, 106 2 of 17 the factors that significantly influence people's thermal comfort, wind speed (V a ) was found to play a key role in cities and particularly in densely built-up areas and between buildings [5,6].Research on wind comfort perception is underpinned by four major methods: software simulations, field tests, wind tunnel tests and questionnaire survey [6]. Questionnaire survey on people's feeling about wind speed is believed to provide accurate, comprehensive and cost-effective method. Since this method evaluates the impact of four parameters (T a , RH, V a, and T mrt ) it is possible to gain an insight into the impact of V a in comparison with the other three parameters. Several studies have demonstrated the significant effect of V a on outdoor thermal comfort [7][8][9]. For instance, the study by Walton, Dravitzki and Donn [7] revealed that gustiness and V a were the most significant factors in shaping outdoor thermal satisfaction. The results of a questionnaire survey in Hong Kong [9] showed that participants were highly sensitive to V a fluctuations. In urban open spaces, it is widely known that recent drastic changes in the design of building density and configuration in cities influence V a profile [5,[10][11][1...
