| 摘 要： | 利用Radiance和Daysim等光照模拟软件对百叶外遮阳从照度、光照均匀度、眩光等多方面定量分析其倾角的变化对室内光环境的影响情况。选择了三个处在不同光照分区的城市分析在不同的全年光照条件下百叶遮阳不同倾角对室内全年照明能耗的影响。模拟结果显示:百叶对室内照度的影响很大,百叶遮阳在90°时,室内照度下降了70%,60°时下降了86%,30°时下降了93%;百叶遮阳的增加可以有效地提高室内照度的均匀性;晴天,百叶遮阳可以有效降低室内照度至视觉舒适度范围,阴天,其对室内照度不利,导致室内照明能耗增加;在不同光照条件下,百叶遮阳对全年照明能耗的影响不同。 |

| Abstract: | With the light simulation software,Radiance and Daysim,quantitative analyses about the changing of blinds angle how to effect the indoor illumination were carried.Three cities were selected out to analyze the different blinds angle impacting the annual lighting energy consumption in different annual light conditions.Simulation results show: the blinds and its angle changing has a large impact for the indoor illumination,when blinds is in 90 degrees,the indoor illumination down 70%,and 60 degrees down 86%,an... |
| Keywords: | the outer blinds illumination illuminance uniformity lighting energy consumption |
