当靠近道路时，不适当的自然通风做法可能会恶化室内空气质量，尽管其目的通常是减少能源消耗。在这项研究中，我们采用了基于CFD的空气质量模型来量化交通相关的空气污染对自然通风建筑的室内空气质量的影响。我们的研究发现，建筑围护结构限制了颗粒物的分散和稀释。在基线条件下，距离道路10 m处的室内浓度大约比道路边缘处的浓度高16-21%。室内流动再循环产生细颗粒浓度变化很小的良好混合区（即，253 nm）。对于超细颗粒（
Improper natural ventilation practices may deteriorate indoor air quality when in close proximity to roadways, although the intention is often to reduce energy consumption. In this study, we employed a CFD-based air quality model to quantify the impact of traffic-related air pollution on the indoor air quality of a naturally ventilated building. Our study found that the building envelope restricts dispersion and dilution of particulate matter. The indoor concentration in the baseline condition located 10 m away from the roadway is roughly 16-21% greater than that at the edge of the roadway. The indoor flow recirculation creates a well-mixed zone with little variation in fine particle concentration (i.e., 253 nm). For ultrafine particles (
