Effects of angles of the exterior window shutter on daylighting ability

指導教授 : 謝明燁 曹拯元

摘要


摘 要 評估室內採光是否良好的依據包括整體的「均齊度」以及各測量點「照度比」的高低。因此,本研究擬以上述兩指標作為依據,探討不同水平垂直百葉角度遮陽情況下,室內照度比與均齊度的差異,以瞭解那一種角度範圍具有較佳的採光效能。本研究之主要目的為了解在不同角度之水平垂直百葉,在不同月份、時段、方位等條件下,對室內各測點照度比及均齊度之影響。根據照度比與均齊度的結果,綜合分析不同角度之水平垂直百葉採光效能 ,充實採光方面之基礎資料庫,以供建築設計或後續研究之參考 。本研究顯示水平百葉角度在照度比方面,時段、方位、角度因子對室內採光照度比均有顯著影響,如以時段、方位兩項同時當因子進行變異數分析,時段、方位因子對室內採光照度比影響是上午南向>下午南向、上午東向>下午東向、下午西向>上午西向。垂直百葉角度在照度比方面時段、方位、角度因子對室內採光照度比均無顯著影響。水平百葉角度在均齊度方面,時段因子對室內採光均齊度有顯著影響,方位與角度對室內採光的均齊度並無顯著影響。垂直百葉角度在均齊度方面,時段因子對室內採光均齊度有顯著影響,方位與角度對室內採光的均齊度並無顯著影響,如以時段、方位兩項同時當因子進行變異數分析,時段、方位因子對室內採光均齊度影響是上午南向>下午南向、下午東向>上午東向、上午西向>下午西向。

Abstract The criteria for evaluating the quality of indoor lighting include overall uniformity and the ratio of illuminance at various measuring points. This study plans to discuss the differences in indoor illuminance ratio and uniformity in the case of shading at different angles of horizontal and vertical blinds based on the aforesaid two indexes, so as to determine the range of angle that has a better lighting performance. This study aims to learn about the effect of horizontal and vertical blinds at different angles on the ratio of illuminance and uniformity at various indoor measuring points in different months, time intervals and orientations. According to the results of ratio of illuminance and uniformity, the lighting performance of horizontal and vertical blinds at different angles is analyzed comprehensively. The basic database of daylighting is enriched, so as to provide references for architectural design or subsequent research. The findings show that in terms of the effect of the angle of horizontal blinds on the ratio of illuminance, the time interval, orientation and angle factors have significant impact on the indoor lighting illuminance ratio. If the time interval and orientation are used as factors for ANOVA, the effect of time interval and orientation factors on indoor lighting illuminance ratio is morning south > afternoon south, morning east > afternoon east, afternoon west > morning west. In terms of the effect of the angle of vertical blinds on the ratio of illuminance, the orientation and angle factors have no significant impact on the indoor lighting illuminance ratio. In terms of the effect of the angle of horizontal blinds on the uniformity, the time interval factor has a significant impact on indoor lighting uniformity, and the orientation and angle have no significant impact on indoor lighting uniformity. In terms of the effect of the angle of vertical blinds on the uniformity, the time interval factor has a significant impact on indoor lighting uniformity, and the orientation and angle have no significant impact on indoor lighting uniformity. If the time interval and orientation are used as factors for ANOVA, the effect of time interval and orientation factors on indoor lighting uniformity is morning south > afternoon south, afternoon east > morning east, morning west > afternoon west.
