基于非视觉效应的高校图书馆阅览空间天然采光设计研究

Research on Natural Lighting Design for University Library’s Reading Space Based on Non-visual Effect

随着对人体非视觉通道研究的深入,天然光与人体生理节律的密切关系被更多地证实,高校图书馆阅览空间中天然光环境设计亟需重新审视和思考。文章对高校图书馆阅览空间的天然采光设计进行展望:在考虑外部环境的天然光条件下,高校图书馆阅览空间应优先考虑设计东朝向的采光口,其次为南朝向;应充分利用采光中庭,多选用正方形的空间形状;分区式和夹层式空间布局更利于提高侧窗天然光线的射入量;多立面采光幕墙、天窗采光和室外阅览区域能让阅读环境天然光线丰富立体;考虑到读者的个人感光史可利用遮阳系统和采光辅助系统进行微调节。

With the in-depth study of human non-visual effect,the close relationship between natural light and physiological rhythm has been confirmed.Natural light environment design in the reading space of university libraries urgently needs to be re-examined and considered.This paper analyzes the research on the natural lighting environment design of reading space in University Library:In consideration of the natural light conditions of the external environment,the reading space of university library should give priority to the east direction as daylight opening direction,followed by the south direction;The light atrium should be fully used,and the square space shape should be selected;The partition and mezzanine spatial layout is more conducive to improving the natural light input of the side window;Multi-facade lighting curtain wall,skylight and outdoor reading area can enrich the daylight of reading environment;In consideration of the readers’personal photosensitive history,the sun shading system and lighting auxiliary system can be used for micro adjustment.
