Solar chimneys as an element of natural ventilation in modern building practices

The article addresses the investigation of a solar chimney as a component of passive ventilation in energy-efficient residential buildings. A comprehensive literature review was carried out, focusing on energy-saving technologies and the role of occupants in influencing the performance of natural ventilation. To evaluate the operational characteristics of the solar chimney, mathematical modeling was performed using the MATLAB R2024a environment. The obtained results demonstrate the dependence of temperature, pressure, mass flow rate, and air velocity within the solar chimney channel on the intensity of solar radiation. The analysis confirmed that the system ensures stable air exchange and a notable increase in outlet air temperature with rising solar radiation. The findings provide practical insights for the design and optimization of passive ventilation systems incorporating solar chimneys in energy-efficient buildings.
