In this present study, annual exceedance probability (AEP) analysis was applied as the method forassessing wind-driven natural ventilation in a street canyon, in which the effects of wind approachingfrom each direction were comprehensively taken into account. In order to evaluate the overallventilation performance in specific domain spaces within the street canyon, local air change rate andaverage kinetic energy were employed to calculate the AEP, instead of using the commonly adoptedvelocity ratio.
