“…Also, with its building model detailing in the concept of level of development, where the development process differentiates it from the construction to the as-built design. However, although with excellent building information provided in the BIM environment, this is somehow is not very useful as the CFD simulation is focusing more on the geometry of the building to be included in the simulation [46]. This is because there is one process called meshed of geometry in the CFD environment.…”

Computational Fluid Dynamics (CFD) simulations are used to monitor air pollution events supported by real-world conditions digitally. Besides, wind flow that has a close relationship with air pollutants dispersion also can be visualized by using CFD simulation. The presence of a building, especially in terms of the building’s geometry, impacts the air pollution dispersion and wind flow that occur around a building or in a specific research area. As there is an involvement of building models in the simulation, some of the standards for the building modelling: Computer-Aided Design (CAD), City Geographic Markup Language (CityGML), and Building Information Modelling (BIM), are being utilized in this type of study. Many types of research have been conducted to study the pollutants and wind flow using the CFD technique of these three standards. Hence, this review paper is used to presents several pieces of research on this related topic. Through this review paper, some of the drawbacks of the study were identified, such as the detailing of the building’s geometry and the compatibility of each standard to be implemented in the CFD simulation.

“…Although the guideline summarized by Frank et al [34] is universal, the size of computational domain can be adjusted appropriately according to the required blockage ratio. For instance, Kaseb et al [39] studied the influence of the building group layout on the wind speed at the pedestrian height. He took the distance between the outlet of the computational domain and the area of interest as 10 H max , and the distance between the inlet and the area of interest as 6 H max , and found that simulation results were not much different from the results of the wind tunnel test.…”

Computational fluid dynamics (CFD) has become the main method for the prediction of the properties of the external wind environment in cities and other urban contexts. A review is presented of the existing literature in terms of boundary conditions, building models, computational domains, computational grids, and turbulence models. Some specific issues, such as the accuracy/computational cost ratio and the exploitation of existing empirical correlations, are also examined.
