This article is the first in a series aimed at defining the methodology for applying numerical modeling in predicting microclimate parameters. The article discusses the methods and materials used for the research and presents the results of a comparison between a field experiment and the outcomes of numerical modeling using the k-ε turbulence model under the combined influence of engineering systems on microclimate formation. Subject of the study: microclimate parameters and their convergence in field experiments and the application of the k-ε turbulence model. Materials and methods: The field experiment was conducted in real-world conditions in a university lecture hall using certified equipment. The evaluation of turbulence models was performed through numerical modeling in the FlowSimulation SolidWorks software suite. Results: Tables with values of air velocity and temperature in characteristic zones of the lecture hall were obtained both experimentally and through numerical modeling. Conclusions: A significant discrepancy was identified between the results of the field experiment and the numerical modeling using the k-ε turbulence model for air velocity under the combined influence of engineering systems on microclimate formation.
