摘要

摘要: 绿色住区开放空间中的太阳辐射对热环境有重要影响，为创造绿色宜居经济的住区室外空间，研究室外空间的太阳辐射量具有基础价值。基于参数化软件平台Rhino-Grasshopper，借助性能化模拟插件Ladybug，利用天空开阔度的遮挡投影算法原理，实现天空开阔度的自动计算。通过实际住区太阳总辐射测试与基于天空开阔度的太阳辐射模型计算对比，验证该简化计算方法具有较高的计算精度和稳定性，可满足工程设计的需要。同时利用理论住区模型，分析绿色住区设计参数对太阳辐射的影响，结果表明建筑密度与太阳辐射呈负相关，容积率、平均建筑高度与太阳辐射的相关性受建筑密度的影响，且相关性因太阳高度角而异。

Abstract: The solar radiation in the open space of urban residential areas has an important impact on the thermal environment. In order to create a livable and economic residential outdoor space, it is of fundamental value to study the amount of solar radiation in the outdoor space. Based on the parameterized software platform Rhino-Grasshopper and with the help of the performance simulation plug-in Ladybug, the shadow angle projection algorithm principle of the sky opening factor was adopted to realize the automatic calculation of the sky view factor (SVF). Compared with the calculation of solar radiation model based on SVF, it was proved that the simplified calculation had high calculation accuracy and stability, and could meet the requirements of engineering design. At the same time, using the ideal settlement model to analyze the influence of green settlement design parameters on solar radiation, the results showed that building density was negatively correlated with solar radiation, and the correlation of plot ratio, average building height and solar radiation were affected by building density, and the correlation varied with the solar height angle.
