学校中小型体育馆自然采光模拟分析

Simulation Analysis of Natural Lighting on Medium and Small School Gym

针对学校中小型体育馆建筑特点,以生态建筑设计软件Ecotect模拟了不同窗地比、窗户数量、窗户间距条件下的天窗设置对室内场地自然采光的影响。基于模拟数据,分析其对采光系数、均匀度、光线方向性等的影响变化趋势,结果表明:随着开窗数量增加,室内最高采光系数增加幅度加大,而室内最低采光系数增加幅度逐渐减小,均匀度在一定范围内增加明显,达到一定程度后提高有限。最后,提出本类型建筑自然采光设计应该注意的问题。

Aiming at the characteristics of medium and small school gym, the influence of the indoor daylight distribution of different glazing-floor ratios, window quantities and window spacing on the skylight of gymnasium was analyzed with the usage of Ecotect. Based on simulative data, the diagram of the influence of daylight factor, uniformity and direction of daylight was carried out. The results show that the increase rate of the maximum value of daylight coefficient becomes intense and of the minimum value of daylight coefficient is on the contrary with the increase of times of opening windows. The uniformity of daylighting increases significantly within a certain range, but then the increase is limited in the back range. At last, the key points and ways of daylight design for the gymnasium were presented.
