摘要
自然采光是教学建筑的重要组成部分,对改善室内光环境、提高师生的生理和心理健康、提高学习成绩、节约建筑能耗和保护环境都有重要的意义。本文提出了教学建筑自然采光需求的特点,以及目前教学建筑自然采光设计存在的问题,从而提出一种新型的适用于教学建筑的自然采光技术——镜面反光玻璃板,该技术应用了镜面反射原理,反光效果类似于微型折光百叶帘,但它成本较低,使用时间长,适用范围广,清洗维护较为方便。本文通过数学计算推导出其组成单元截面的高度和宽度的比值D/W与其反光效率之间的关系式,不同纬度地区的设计者可以根据这些关系式很容易推导出该地区适合采用何种镜面反光玻璃板。最后,本文论述了镜面反光玻璃板在建筑自然采光设计中的应用方式,为建筑师提供有价值和实践意义的参考。
Daylighting is one of the most important parts in school building design,which is of great significance to improving the lighting environment,the health of teachers and students＇ bodies and psychology,the test scores of students,energy conservation and environment protection. Characteristics of daylighting requirement in school buildings and the corresponding problems of daylighting design are put forward in this paper. Based on this,the paper proposes a new type of daylighting technology—Reflective Mirror Glass Panel（ RMGP）. The relationship between the ratio D/W and the RMGP＇s reflective effect is derived through mathematical calculations. Designers in any different latitude area can easily derive what kind of RMGP they should use for their areas through these mathematical calculations. Finally,this paper discusses the applications of RMGP in school building design,which provides valuable reference with practical significance for designers.
