Abstract

Abstract:

Under the background of insufficient school places and shortage of construction land in large and medium-sized cities in China, the three-dimensional design of primary and secondary school campus sports fields can form a vertical superposition of space, thereby releasing a large amount of construction land. However, the three-dimensional design of sports fields will also lead so some new design problems. Among them, the most complicated is the natural lighting of the lower space of the sports field, which facing both the problem of whether the illumination is sufficient and the problem of whether the light distribution is uniform. Domestic and foreign literature research shows that the current research on the lighting of three-dimensional sports venues at home and abroad is almost blank, which makes the current construction somewhat blind. Based on the above considerations, the study simulated the natural lighting environment of the lower area of different forms of campus three-dimensional sports venues with the parametric light environment simulation technology of the lighting simulation platform built based on Rhino, Grasshopper and Ladybugtools. And it extracted the factors affecting the lighting of the lower space of the three-dimensional sports field, including the size of the stadium, the number of overhead layers, the depth of the space, the functional layout, the location of the lighting port, and the sunshade and reflection measures. By simulating and analyzing the influencing factors, the influencing mechanisms of different factors were obtained, and the design strategies for three-dimensional sports fields to create a good natural light environment were further refined. The research feedback was formed based on the practice of optimizing the natural light environment of the student activity center of the Guangzhou Experimental Middle School project, thereby verifying the effectiveness of the research.
