In this work, an analysis of modern approaches to optimizing the energy consumption of ventilation systems in public
catering facilities is carried out. Regulatory requirements for air quality and microclimate parameters are considered, in
particular the permissible levels of CO₂ concentration and temperature. Based on the analysis, it was found that traditional
systems with constant air supply have increased energy costs and do not always ensure optimal conditions. A mathematical
model is proposed that describes the energy consumption of the ventilation system, as well as the changes in CO₂
concentration and indoor temperature depending on the ventilation operating mode. Two scenarios are implemented: constant
air supply and optimized variable supply regulated according to the load. The calculations were performed in the MATLAB
environment, and the results were visualized in the form of graphs indicating regulatory limits and key points. The simulation
showed that the optimized mode allows for a significant reduction in energy consumption while maintaining comfortable
conditions. A quantitative comparison of energy costs for both modes was carried out, confirming the effectiveness of the
approach. The results of the work can be used to modernize ventilation systems in public catering facilities. The proposed
method can also be adapted for other types of public buildings.
