A three-dimensional model consisting of four buildings and a chimney was established, and the smoke diffusion from chimney pollutants in east and west wind conditions was calculated with computational fluid dynamics. The results show that the flue from chimney may pollute its neighbor buildings. When a new high-rise building is located at the downstream of a chimney, the residents at the top part of the building will suffer because the gaseous pollutant can rise to the top along walls. Even so, the air quality would be improved by adjusting the building layout. In this case, it is observed that the pollution around the new high-rise building has been mitigated after changing the relative position of the building and the chimney.
