Abstract

Urban climatic conditions have a profound impact on the comfort levels experienced by citizens, making it essential to enhance building thermal performance by strategically utilizing regional microclimates. This research delves into the intricate relationship between different street and block orientations, particularly how these align with the prevailing wind directions, and their subsequent effects on wind speed and overall climate comfort in the city of Tabriz. The focus is to determine the most effective urban land separation practices that would facilitate climate adaptation in Shahriar, a region characterized by its cold, mountainous terrain. To achieve the objectives of this study, a descriptive-analytical methodology was employed, which included conducting detailed simulations utilizing RWIND Simulation 1.75 software, alongside an analysis of urban land separation using the capabilities of CIVIL3D 2022. The results obtained from these simulations were meticulously compared against the DAVENPORT wind comfort criteria. This assessment aimed to evaluate various comfort levels, highlighting areas of discomfort as well as ranges deemed unbearable for inhabitants. The findings of this research underscore the importance of aligning urban land separation practices with the specific local climate as well as the topographical features of the area, which can result in a significant improvement in climate comfort for residents. In particular, in cold, mountainous regions where wind patterns play a pivotal role in determining comfort, it is essential to establish that urban lands are separated at a minimum angle of 45 degrees from the direction of the wind. The modeling conducted for the New Shahriar town illustrated that incorporating design considerations that are informed by the local topography can lead to the highest levels of climate comfort for its inhabitants.
