We use large-eddy simulations (LESs) to simulate wind flow through an idealized urban canopy with several building interiors. These interiors include multiple window configurations, probing the efficacy of different ventilation strategies across the domain. By varying wind speed, wind direction, urban density, and indoor temperatures, we investigate how the surrounding urban layout impacts interior airflow. We find that the urban layout generates distinct interior flow rates across buildings that are otherwise identical. We also explore how different measurement techniques for natural ventilation impact our findings.
