Abstract: In order to improve the utilization rate of natural-lighting and the quality of daylighting for a gymnasium, an analog analysis was performed via ECOTECT for the lighting environment of a natural-lighting and top-interface gymnasium in Guangzhou. It is found that when reducing the distance between dormers, raising the dormers’ height, and parallelling the dormers with the length of gymnasium could improve the illuminance and uniformity. When keeping the same area of dormers, maximum values of illuminance and uniformity could be reached via changing the distribution density of dormers.

摘要： 为提升体育馆自然采光利用率，改善运动场地光环境品质，以广州地区为例，通过ECOTECT软件对采用顶界面自然采光的运动场地光环境进行定量模拟分析。通过实验发现：缩小体育馆顶界面天窗间距，增加天窗高度，使天窗与场地长边平行，均能使比赛厅采光照度及均匀度增加；当采光面积一定，改变天窗分布密度时，比赛厅采光照度及均匀度存在最大值。
