基于实测与模拟的高校大进深教室天然采光优化研究OA

Based on on-site measurements and simulation analysis,the natural lighting performance of a large depth classroom in a certain university is evaluated.A building model is established using Rhinoceros,and natural lighting simulation and optimization analysis are conducted using Ladybug and Honeybee.The results show that the original classroom had uneven illumination distribution on sunny winter days,with the average illuminance falling below the standard limit at multiple times.Through parametric modeling and orthogonal experimental design,the lighting performance simulation and optimization analysis are carried out for key parameters such as the window-to-wall ratio of the exterior windows and the height of the window sills.After optimization,the lighting coefficient and effective natural light illuminance of the classroom are significantly improved.On this basis,an energy-saving assessment is introduced,and it is concluded that the optimized design could reduce the annual lighting energy consumption by approximately 206.40 kWh,corresponding to a reduction of approximately 115.171 kgCO2 emissions.The verified the comprehensive benefits of this method in improving the lighting environment and reducing energy consumption.
