Evaluation and Design of Parameterized Dynamic Daylighting for Large-Space Buildings

This study aimed to promote the use of natural lighting in building designs create a good environment and save energy. Dynamic daylight evaluation analysis have become hot research topics due influence outdoor light climate changes that occur throughout season over period time. However, there are certain gaps application dynamic for large-space buildings. In China, static is mainly used assess actual daylighting performance The Hangzhou E-sports Center China was selected as object this research, simulations were conducted using Rhino + Grasshopper Ladybug Honeybee different representative days each measurement zone. Spatial autonomy (sDA) useful illuminance (UDI) indicators, parameterized method proposed evaluating design scheme. By comparing initial optimized schemes, results showed following: (1) scheme increased ratio area time within UDI 100–2000 lux range, areas with an sDA >300 accounted 55% primary areas, indicating significant improvement quality large space; (2) space seasonal changes, best occurring during summer solstice worst on winter solstice, while similar spring autumn equinoxes; (3) metrics facilitated identification issues large-scale buildings more effectively; (4) can solve cumbersome process simulation conducive adjustment optimization schemes by designers. provides references ideas other
