Abstract

The excessive energy consumption in buildings and the associated costs for maintaining thermal comfort necessitate the implementation of effective alternatives to reduce energy demand. Natural ventilation is one of the most efficient solutions, utilizing air circulation within the environment, offering a sustainable and cost-free method. This research aims to analyze the application of natural ventilation in industrial buildings, with the Ghovam-ol-Saltaneh Tea Factory selected as a case study. The study evaluates the performance of an atrium and a solar chimney as potential strategies for achieving thermal comfort in the given environment. The research employs a descriptive-analytical method, gathering data through both library resources and computer simulations using DesignBuilder software to assess thermal comfort conditions for three atrium and solar chimney models during the hottest week of the year (July 21 to July 27). The selected models are subsequently subjected to internal and external CFD (Computational Fluid Dynamics) analysis, allowing the identification of the best-performing configurations for optimizing natural ventilation. Based on the research findings, annual electricity consumption at the site was reduced by 42%, thanks to the incorporation of the atrium and solar chimney, indicating their potential as viable alternatives to conventional energy sources (electricity) in providing thermal comfort.
