摘要(Abstract)：

针对城市建筑表面太阳能利用的迫切需要问题,该文提出一种屋顶及立面太阳辐照度一体化计算方案。该方法以机载LiDAR点云为数据基础,以"建筑遮挡分析—天空视域分析—太阳辐照度模型构建"为技术框架,高效率和准确地计算了建筑屋顶及立面辐照度。同时,将散射辐射分为环日散射、天穹散射和建筑散射,提高了建筑散射辐射计算准确度。选取南京奥体新城约30 km~2区域(共计5 216栋建筑)进行分析,结果表明,建筑屋顶直接辐照度时间变化规律明显,受太阳高度角、屋顶坡度和坡向影响较大,而建筑立面太阳辐照度则主要受建筑朝向影响。利用本文方法计算建筑表面太阳辐照度,可为光伏发电模拟、建筑形态设计、城市能源规划等提供基础信息产品。
