The paper provides an overview of CFD solutions for architectural design and urban planning. Aspects of numerical modelling of the aerodynamics of buildings and structures are described. Examples of the influence of turbulence models on flow parameters in the vicinity of buildings, as well as examples of influence of thermal stratification regimes on flow structure around buildings and on concentration of gaseous emissions from low sources in the vicinity of these buildings are considered. The calculation results of aeration of a city micro-district and a scenario for the arrangement of green areas to change the wind regime of the territory with the already existing development are demonstrated in the paper.
