沈阳地区办公室工作区眩光模拟研究——以沈阳建筑大学机关办公室为例

Glare Simulation of Office Area in Shenyang:Analysis of an office in Shenyang Jianzhu University

在自然采光条件下,办公室内部产生的眩光是引起人视觉不舒适的重要原因之一。由于办公工位及周围的视线可达范围为人眼长时间停留区域,该区域的舒适程度直接影响办公室内的体验。以沈阳建筑大学一处机关办公室为例,基于Ladybug和Honeybee软件,完成不舒适眩光指数DGI及不舒适眩光概率DGP的模拟;通过对室内特定区域范围的光环境模拟,得到其全年典型光照日的眩光规律,即该办公室眩光发生的时间段为1-3月及9-12月的上午,而最不利状态则为冬至日的上午;在得到此规律的基础上,探索引起不舒适眩光的可控因素并提出相应的改造策略,以减少眩光的发生并提高特定工位工作区的光舒适度。

Under the condition of natural lighting,glare in office work area is one of the important reasons for staff’s visual discomfort.Since the sight range of the office station and its surroundings is the area where the human eye stays for a long time,the comfort degree of this area directly affects the experience in the office.An office in Shenyang Jianzhu University is analyzed,simulating the uncomfortable glare index DGI and uncomfortable glare probability DGP based on Ladybug and Honeybee software.By simulating the glare in the specific shape area of the office,the glare law of the typical light day of the whole year was obtained,that is,the time period of glare occurred in the morning of January-March and September-December,and the most adverse state was the morning of the winter solstice.On the basis of this law,the controllable factors causing uncomfortable glare are explored and the corresponding transformation strategies are proposed to reduce the occurrence of glare and improve the light comfort in specific working areas.
