Abstract: (148 Views)
Introduction: Despite the significant effects of atriums on lighting and reducing energy consumption, there is not enough knowledge about the effect of different design parameters on its lighting performance. For this reason, this research examines the effect of the physical factors of the atrium on the lighting demand of high-rise buildings in Rasht city through lighting performance simulation. The final goal of this research is to achieve a prediction model of lighting demand based on the physical factors of the atrium for high-rise buildings in Rasht city. The final goal of this research is to achieve a prediction model of lighting demand based on the physical factors of the atrium for high-rise buildings in Rasht city.
Methodology: For this purpose, the length, width, perimeter, area and orientation of the atrium have been considered as independent variables in a reference building with fixed specifications. With the changes in the independent variables, the results of the lighting requirement have been evaluated. Lighting simulation is done in Design Builder software. The results obtained from the simulation, in addition to being analyzed in the form of descriptive statistics, have been subjected to correlation and regression tests.
Results: According to the findings, among the architectural variables investigated in this research, the width, area, and environment of the atrium have the greatest effect on the lighting demand, and the orientation angle of the atrium has not had much effect on the lighting performance of the building. Simulated atriums have reduced lighting demand from 4% to 17%. Furthermore, the study infers that atrium length and width, as well as its perimeter and area, exhibit a significant inverse correlation with the building's lighting demand in a ten-story, 20×20 meter model building in Rasht, with a window-to-wall ratio of 50%.
Conclusion: This study investigates the impact of atrium physical parameters on the daylighting performance of high-rise buildings in the city of Rasht. Based on the findings, it can be concluded that variations in the physical characteristics of atriums have a direct influence on the daylight performance of high-rise buildings in this specific geographic context. To better assess the outcomes, an initial simulation was performed on the model building without an atrium and without orientation, showing a lighting demand of 6971.348 Wh/m². Accordingly, the simulated atriums
