分析目的天然光营造的光环境以经济、自然、宜人、不可替代等特性为人们所习惯和喜爱。各种光源的视觉试验结果表明，在同样照度条件下，天然光的辨认能力优于人工光。天然采光不仅有利于照明节能，而且有利于增加室内外的自然信息交流，改善空间卫生环境，调节空间使用者的心情。在建筑中充分利用天然光，对于创造良好光环境、节约能源、保护环境和构建绿色建筑具有重要意义。窗的不舒适眩光是评价采光质量的重要指标，绿色建筑评价中也要求对主要功能房间有合理的控制眩光的措施。本分析报告以相关标准为依据，采用Dali软件进行采光模拟，分析项目主要功能房间眩光指数，并给出绿色建筑评估所需要的评价分值。3. 分析依据3.1 标准依据1. 建筑采光设计标准GB 50033-20132. 绿色建筑评价标准GB/T 50378-20143. 建筑采光测量方法GB/T5699-20084. 委托方提供的项目总平面图、建筑设计图纸、设计效果图等图纸资料5. 委托方提供的其它相关资料 3.2 标准要求本报告以建筑采光设计标准GB 50033-2013为计算依据，以绿色建筑评价标准GB/T 503782014为评价依据。 建筑采光设计标准GB 50033-2013规定：窗的不舒适眩光指数不宜高于表5.0.3规定的数值。表5.0.3 窗的不舒适眩光指数（DGI）采光等级眩光指数值DGI2023252728 绿色建筑评价标准GB/T 50378-2014规定：8.2.7 改善建筑室内天然采光效果，评价总分值为14分，并按下列规则分别评分并累计： 1. 主要功能房间有合理的控制眩光措施，得6分； 2. 内区采光系数满足采光要求的面积比例达到60%，得4分；3. 根据地下空间平均采光系数不小于0.5%的面积与首层地下室面积的比例，按表8.2.7的规则评分，最高得4分。4. 应用软件与计算方法4.1 软件选用本报告采用绿建斯维尔采光分析软件Dali建模。Dali是国内首款与国标建筑采光设计标准GB50033-2013配套的软件，支持绿色建筑评价标准GB/T50378-2014的采光指标要求。软件以Radiance为计算核心，将计算结果返回到Dali进行处理分析。Dali可对眩光指数、达标率、地下采光、内区采光、视野率等进行快速分析，并根据不同需求生成不舒适眩光分析报告书等系列采光分析报告书。Dali已通过了建筑采光设计标准GB50033-2013标准编制组的鉴定，获得国家建筑工程质量监督检验中心鉴定报告，编号BETC-GMJC-2014-1。同时，Dali还通过了住房和城乡建设部科技发展促进中心专家组评审鉴定，获得建设行业科技成果评估证书，编号建科评2014069，评估委员会认定软件总体已达到国内领先水平。4.2 计算原理 窗的不舒适眩光指数（DGI）可按下列公式计算： 式中：Gn-眩光常数；Ls-窗亮度，通过窗所看到的天空、遮挡物和地面的加权平均亮度（cd/m2）；Lb-背景亮度，观察者视野内各表面的平均亮度（cd/m2）；-窗对计算点形成的立体角（sr）；-考虑窗位置修正的立体角（sr）；P -古斯位置指数-窗对角线与窗垂直方向的夹角；-观察者眼睛与窗中心点的连线与视线方向的夹角。窗的不舒适眩光计算各角度示意图5. 计算参数选用5.1 模拟条件天空状态：CIE 全阴天空，室外照度13500 lx周边环境：考虑分析区内的建筑物之间遮挡室内环境：忽略室内家具类设施的影响，只考虑永久固定的顶棚、地面和墙面、。5.2
