This study adapted the mean age of air, a time scale widely utilized in evaluating indoor ventilation, to assess impact building layouts on urban ventilation capacity. To distinguish it from its applications enclosed environments, index was termed effective air (τ¯E). Based an experimentally validated method, computational fluid dynamic (CFD) simulations were performed for parametric studies four generic parameters that describe morphologies, including height, density, and variations heights or frontal areas adjacent buildings. At breathing level (z = 1.7 m), results indicated three distinct distribution patterns insufficiently ventilated areas: within recirculation zones behind buildings, downstream sections main road, near lateral facades. The spatial heterogeneity capacity emphasized through statistical distributions τ¯E. In most cases, convective transport dominates purging process whole canopy zone, while turbulent prevails pedestrian zone. Additionally, comparisons with reference case simulating open area highlighted dual effects buildings notably enhanced dilution promoted by helical flows between also serves as preliminary CFD practice utilizing τ¯E homogenous emission demonstrates capability assessing potential planning.

Abstract Outdoor environment modelling is crucial for multiple facets of a sustainable urban development, such as mitigating the detrimental environmental impacts (i.e. greenhouse gas emissions), proposing energy-efficient building designs, optimizing usage green resources, and improving overall comfort level residents. This paper presents comprehensive review techniques models related to various aspects an outdoor modelling, including microclimate dynamics solar radiation wind-flow air-temperature assessment simulations, urban-canyons heat island effects green-infrastructure planning. Each section covers compares traditionally used methods in field with newer artificial intelligence (AI) based models, aiming explore their relevant efficiencies areas improvement. For instance, microclimate’s traditional like radiative transfer are evolving machine-learning high-resolution remote sensing methodologies community-based participatory models. Similarly, encompasses CFD, wind-tunnel modified by machine learning (ML) data-driven methodologies. Moreover, also discusses (UHI) phenomenon Overall, aims provide state art on cutting-edge all necessary help informed decision-making environments.
