Abstract
Passive solar systems represent an effective approach for reducing energy consumption in buildings. This study investigates the dual‑season performance of a segmented vertical solar chimney integrated into an eight‑story residential building located in the Saadat Abad district of Tehran. Five key design parameters, chimney depth, chimney height, glazing type, insulation thickness, and absorber thickness, were selected and evaluated using the Taguchi design of experiments method with an L18 orthogonal array. Building energy simulations were conducted in Design Builder for all 18 design configurations, and the resulting data were subsequently analyzed using Qualitek‑4 to determine the influence of each parameter on the design objectives, including the reduction of heating energy consumption, cooling energy consumption, total energy consumption, and CO₂ emissions. Analysis of variance (ANOVA) indicated that chimney depth is the most influential parameter affecting system performance. The optimal configuration resulted in a 4.17% reduction in heating energy consumption, a 1.4% reduction in cooling energy consumption, and an annual reduction of approximately 1.6 tons of CO₂ emissions. These findings demonstrate that the dual‑season segmented vertical solar chimney can effectively improve building energy performance and mitigate environmental impacts in the cold semi‑arid climate of Tehran.
