An overview of methods for assessing the state of the environment is presented. The study of methods for assessing the state of the environment and the impact of production facilities is the most important factor contributing to reducing the negative impact on the environment. An example of a comprehensive assessment of atmospheric air in the Motovilikhinsky district of Perm using the Jobs-Decon software package is considered.

Studies of the possibilities of BIM modeling in the field of ventilation systems design show that the current level of development of BIM technologies allows for aerodynamic calculation. An example of software with such capabilities is Autodesk Revit. This article provides a comparative analysis of two calculation methods: according to the standard methodology and the Colebrook formula, calculated on Revit software. The calculation error was 14.08%, which does not exceed the permissible value of 15%. Thus, the prospects of using the Revit program to perform aerodynamic calculations are shown.
