The sustainable development of settlements is increasingly linked to the development of information technologies, which can help identify critical and risky locations based on already detected information. By properly utilizing the advantages of individual systems, effective simulations can be created that will help municipal administrators ensure the expected quality of the environment or mitigate the impacts of the negative effects of the external environment. This article presents an example of the synthesis of several systems used in building information modeling and uses them for modeling and simulating external factors in the built environment. By appropriate application of the methods, places of interest that are affected by the negative effects of air flow, or the spread of pollution through the built environment, were illustratively visualized. The presented study was created based on publicly available data on air pollution in the territory of Ostrava city.
