建筑日照分析原理与计算方法的研究

本文全面系统总结介绍了开发建筑日照分析CAD软件所涉及基本原理、核心计算加速技术、极限容积计算和目前工程实际应用情况。例如太阳位置计算原理、平面等时线百万级采样点大规模分析内部采用的计算加速技术，日照分析根据国内目前各地日照规范要求在工程应用中常用典型的分析方法，日照分析后期的结果表现、如实时表现建筑物阴影，日照分析表格和报告书，日照分析研究的扩展领域，如太阳能计算和综合利用、玻璃幕墙反射光污染评估计算和遮阳装置设计等内容进行了系统简要的介绍。文中论述的许多核心技术和分析方法目前已经应用在PKPM建筑工程软件研究所研发的SUNLIGHT日照分析软件中，对日照分析CAD软件的进一步研究有一定的参考价值。

Research On Building Sunlight Analyse Theory and Compute Methods

This paper summarize basic theory,compute accerlate technology and application of building sunlight analyse CAD program. Such as compute the position of sun,large scale points analyse accerlation technology,It introduce some basic analyse methods based on local sunlight time-long compute stands,the represention of compute result,such as real-time drawing building shadows,sunlight analyse table and report. Above sunlight traditonal analyse areas ,some extended areas,such as compute and utilitize soloar exposure energy,glass wall reflection and sunlight pollution,shading device design are also discussed in this paper. The methods and technologies discussed in this paper have been used in PKPM sunlight.
