Research on the Impact of Cavity Insertion on the Daylight Environment of Sports Buildings

The sports center is a new type of sports building with high participation and high lighting energy consumption. A typical building model is constructed and analyzed by combining Rhino Grasshopper and Ecotect simulation software, and the passive strategy of placing cavities is used to reduce the lighting energy consumption and improve the lighting coefficient, which is beneficial to the health and visual comfort of users. Data analysis revealed that built-in cavities are effective at increasing the average illuminance of the underlying space. For spaces with glare, using skin cavities significantly reduces the possibility of discomforting glare. In the architectural design of the sports center, the form, size, number, material, and other factors of the cavity should be carefully considered to meet the demand for daylighting and improve the comfort of the indoor light environment, which provides a valuable reference for the architectural design of the sports center.
