Study Of The Natural Lighting Design Strategy Of Basketball Gym In GuangZhou Area

With the advent of the national fitness program, training venue of basketball or badminton become more and more required for people. At the same time, more and more various types of training venues are in the construction. However in the past, the designers were not paying enough attention to natural light environment of training venu, so that quite a lot of established training venues are not fully adapt to the needs of natural daylighting for daily exercise. Many venues have to use artificial lighting even during the day, which leads to the increase of the energy consumption of lighting. However, natural light plays a very important place for athletes. Compared with artificial light, natural light not only can improve the comfortable sensation of sports environment, but also can enhance people’s movement. How to make use of architectural design to improve the indoor light environment of sports place and reduce the problems of poor light environment, at the same time to reduce energy consumption, is one of the important subjects to be solved for sports architectural design and research.Different people and different activities have different requirements for lighting. The traditional norms of daylighting evaluation standard is too general and has limitations. It cannot fully reflect the real demand of natural lighting of sports population in guangzhou region and cannot take the best guide for lighting design.First of all, this article surveys three basketball training venue in guangzhou in each season throughout the year by means of data measurement and questionnaires. According to the data, we analysis the present daylighting situation of the venues, and summarize the main factors that influencing the indoor daylighting. We combine the measured data with daylighting satisfaction questionnaire and calculate the comfort zone of daylight factor, which is adapted to the basketball gym in guangzhou area. It provides a more accurate evaluation standard to lighting design.According to the research and literature, we summarize the main factors influencing the indoor daylighting of training venue. This paper uses Ecotect to simulate the influence levels of various factors including the roof and side walls. We use the evaluation standard combined with the feature of the light environment in Guangzhou area, and make a quantitative analysis further. We conclud the optimized lighting design of basketball training venue, and put forward lighting design strategie that suitable for basketball training venue in Guangzhou. We put forward a architecture design method based on the needs of athletes.
