“…Pearson correlation coefficient analysis of average building height and mean pedestrian-level wind velocity ratio (correlation coefficient/p-level). The findings of a study by Deng et al [35] show that for a business center with a building density of 32.65% and a wind projection angle of 45 • , when the taller buildings are located on both sides of the layout, the mean wind velocity ratio is relatively bigger. Discrepancies may exist between their study and this paper as the studied building density and average building height vary greatly, which leads to different effects on the wind environment.…”

Abstract:In recent years, there has been a frequent occurrence of extremely cold conditions which has had a serious impact on the life of residents of buildings in various locations around the world. However, there have only been a very limited number of studies on the effects of residential area building layout on the winter wind environments, which led to a lack of quantitative guidance for residential area planning in severely cold regions. This study aims to reveal the relationship between (1) the residential areas' building density, floor area ratio, wind projection angle, average building height, and relative position of high-rise buildings, and; (2) the mean wind velocity ratio at pedestrian level in severe cold regions. In this study, the pedestrian-level outdoor wind environments in 24 typical residential areas of Harbin, China, are simulated using ENVI-met software. The results show that the relative position of high-rise buildings in multi-high-level mixed residential areas has little influence on the mean wind velocity ratio, and the maximum difference is 0.04. The factors of building layout have little influence on the mean wind velocity ratio of multistory residential areas. However, a significant linear correlation exists between the mean wind velocity ratio of high-rise residential areas and both the building density and wind projection angle. The prediction model of the mean pedestrian-level wind velocity ratio was then established.

“…High-Rise buildings are dominant elements in urban architecture due to their scale and purpose, and should be the focus of sustainable design (Ali & Armstrong, 2008).The microclimate parameters in outdoor spaces, including the air temperature, wind speed, relative humidity, solar radiation etc., are significantly influenced by various configurations of urban texture, such as plot ratio, site coverage, building height, and building arrangement etc (Deng, Wong, & Zheng, 2016).Wind is fundamentally caused by heat radiated by the sun. Radiation, thermodynamic and mechanical phenomena transform the thermal energy imparted to the atmosphere into mechanical energy associated with air motion, giving rise to various types of wind (Simiu, 2011, p. 109).Wind flows that affect buildings and other structures are characterized by two fundamental features: (1) the increase of the wind speed with height, and (2) the atmospheric turbulence (Simiu, 2011, p. 117).…”

High-Rise buildings with their particular features can affects on surrounding environment and makes new microclimates. In the windy conditions, the spaces that are between building blocks changes to passages and affects on the wind velocity, intensity and it's other parameters.The importance of this effect is different in each level of building height. The Pedestrian-Level is the lowest and one of important areas. Markets, playgrounds and pedestrian access had located in this area and any unwanted microclimate changes like high velocity and turbulence in this level can makes discomfort and dangerous condition for residents. So this research tries to consider the pedestrian-level wind comfort in some High-Rise building complexes arrangement that had located in Tehran district 22 with Computational Fluid Dynamics (CFD) modeling and reaching to a suitable arrangement pattern. It had collected the required data through field study and librarian databases and then compared them with standard guidelines and analyzed them by comparative comparison method. As a result a linear arrangement that placed crossover to wind direction for providing wind comfort and preventing wind danger is been suggested in this region.

“…Shafaghat (2016) reveals how road geometry influences the formation of microclimates in one area, especially in coastal tropical climates. Microclimate is influenced by various factors including morphological characters (Kushol, 2013;Ok, 2014;Pandya, 2014), geometric patterns (Deng, 2016), construction material (Santamouris, 2012;Shishegar, 2013;Chokhachian, 2017), orientation (Shishegar, 2013;Sanusi, 2015), building density and building height (Nasira, 2016) and green space/ vegetation (Klein, 2014;Duarte, 2015).…”

In step with economic growth, Pontianak City continues developing its physical development. From an environmental perspective, physical development that does not pay attention to the environment may make air temperature rise and create inconvenience to human. The purpose of this study is to evaluate the tendency in the built/physical environmental aspects that have the possibility of influencing the microclimate in the urban center, regarding the trade area in Pontianak City. Built environmental aspects such as building density, building height, materials, etc. are described and then simulated towards the existing climate elements such as temperature, humidity, solar radiation, cloud cover, and others. The simulations used three-dimensional software ENVI_MET version 4. From findings, it can be seen that the built environment characteristics can affect the microclimate condition. From the simulations, the dominant temperature differences may occur in such built environment conditions such as density, dimensions, location, material, and vegetation closure.
