遮阳构件对透明围护结构太阳辐射得热影响

Influence of Sunshade Member on Solar Radiant Heat Gain of Transparent Enclosure

通过光环境模拟软件,分析建筑各立面遮阳构件对太阳辐射能的影响。对于大进深公共建筑来说,设置遮阳构件与未设置遮阳构件相比,遮阳构件对减少太阳辐射得热贡献率达50%以上。遮阳构件对不同朝向立面遮阳效果不同,东、南两侧遮阳构件对于太阳辐射能的有效遮挡更明显。

The influence of the sunshade member of each facade of buildings on the solar radiation energy is analyzed by light environment simulation software.For large-depth public buildings,the sunshade member contribute more than 50%to reduction of the solar radiant heat gain compared with no sunshade member.The sunshade members have different shading effects on different orientation facades,and the sunshade members on the east and south sides are more effective in shielding the solar radiation energy.
