The complexity of the built environment plays an essential role on the local urban microclimate. Therefore, this work aims to assess the impact of buildings arrangement on the overall turbulent flow dynamics. This study is conducted for the neighborhood of an open auditorium located in an urban area. A set of experiments were accomplished using a wind tunnel, together with a set of Computational Fluid Dynamics (CFD) simulations. Both the experiments and the CFD simulations were carried out for a set of meteorological conditions identified as prevailing in the auditorium area. The physical and numerical approaches were used to assess the wind patterns for the reference scenario. Furthermore, a series of mitigation measures was simulated to evaluate their effectiveness in reducing the wind speed at pedestrian level in the neighborhood. The overall results emphasize the role of the mitigation measures to reduce wind speed and potentially improve pedestrian wind comfort levels in the auditorium. The originality of this paper relies on the design and test of the set of proposed mitigation measures, through the combination of complementary tools, as well as the expertise of distinct practitioners, and their insights regarding their effectiveness.

建筑环境的复杂性对当地的城市小气候起着至关重要的作用。因此，这项工作旨在评估建筑物布置对整体湍流动力学的影响。这项研究是针对位于市区的开放礼堂附近进行的。使用风洞以及一组计算流体动力学（CFD）模拟完成了一组实验。实验和CFD模拟都是针对确定在礼堂区域盛行的一组气象条件进行的。物理和数值方法用于评估参考方案的风型。此外，还模拟了一系列缓解措施，以评估其在降低附近行人水平风速方面的有效性。总体结果强调了缓解措施在降低风速和潜在改善礼堂行人风舒适度方面的作用。本文的独创性在于通过结合互补工具，不同从业者的专业知识以及他们对有效性的见解，对所提议的缓解措施进行设计和测试。
