辦公空間之照明用電密度基準之研究

The Lighting Power Density Standard in Offices

指導教授 : 謝明燁

摘要


摘要 根據經濟部2019 年的非生產性質行業能量查核年表,2018 年辦公大樓的照明設備 佔了建築16.66%的日常使用耗能,僅次於空調設備,顯示辦公空間的照明耗能改善是我 國節能相當重要的一個課題。在辦公室的照明規劃中,我國的辦公室照明規範還是以 CNS12112 之空間照度標準為主,僅對室內作業或活動種類提供維持照度的參考,對節 省耗能的效益有限。 本研究希望建立一個照明用電密度的標準,以「查表簡算法」的概念,讓業主或設 計者能夠根據所需要的照度標準,簡單快速地找到對應的照明用電密度,並計算出所需 要的光源數量。本研究使用照明軟體DIALux 進行3D 建模與燈光模擬,水平作業面設 定為地上72 公分。燈具使用國內辦公室最常見的輕鋼架格柵燈以及平板燈。本研究將 DIALux 照明模擬之數據,進行彙整以及分析,製作成照明用電密度與平均照度的對照 圖。本研究分為「不同室內表面反射率之影響」以及「不同空間元素之影響」兩個實驗 階段。 不同室內表面反射率之影響實驗結果,可彙整出不同平均照度下(300lx、500lx、 750lx),不同光源(T8、T5、LED)之照明用電密度。以平均照度500lx 時為例,T8 的照 明用電密度介於10.98 W/m2-15 W/m2 之間,平均為12.98 W/m2,T5 介於8.51 W/m2-11.7 W/m2 之間,平均為10.06 W/m2,LED 介於7.8 W/m2-9.06 W/m2 之間,平均為8.45 W/m2。 光源的節能效果,LED 光源最節能,T5 次之,T8 最耗能。 不同空間元素之影響實驗中,探討「天花板高度」、「有無隔板」、「辦公座位配置」 三種實驗因子對辦公空間照明之影響。研究結果顯示天花板高度確實會影響整體平均照 度。天花板高度越高,空間照度越低;天花板越低,空間照度則越高。座位加入隔板後 空間照度下降,較不利於照度需求較高之空間。平行式配置與面對面式配置之辦公空間 照度分布沒有明顯差別,兩者照明模擬結果並無顯著差異。

Abstract According to the annual energy verification of non-production industries by the Ministry of Economic Affairs in 2019, the energy consumption of lighting equipment in office buildings accounted for 16.66% of the daily energy consumption of buildings in 2018, second only to that of air conditioner, which indicates that the improvement of lighting energy consumption in office space is an important topic on energy saving in Taiwan. In the office lighting plan, Taiwan’s office lighting specification is still subject to CNS12112 spatial illumination standard which only provides reference for illumination maintenance for indoor operations and activities but has limited requirements on energy saving. This study hopes to establish a lighting power density standard, with the concept of “simple lookup table algorithm”, so that owners or designers can easily and quickly find the lighting power density according to the needed illumination standard and calculate the required number of light sources. In this study, DIALux, the lighting software, was used for 3D modeling and lighting simulation, and the horizontal operation space was set as 72 cm above the ground. Light steel frame grille lamps and panel lamps commonly used in Taiwan’s offices were used. The DIALux lighting simulation data were collected and analyzed in this study to draw a comparison diagram of lighting power density and average illumination. This study consisted of 2 experimental stages: “effects of different interior surface reflectance” and “effects of different spatial elements”. According to the results of experiment on the effects of different interior surface reflectance, the lighting power densities of different light sources (T8, T5, LED) at different average illumination (300lx, 500lx, 750lx) were collected. For example, at the average illumination of 500lx, the lighting power density of T8 was between 10.98 W/m2 and 15 W/m2, with an average of 12.98 W/m2; the lighting power density of T5 was between 8.51 W/m2 and 11.7 W/m2, with an average of 10.06 W/m2; the lighting power density of LED was between 7.8 W/m2 and 9.06 W/m2, with an average of 8.45 W/m2. In terms of the energy-saving effects of the light sources, the LED light source was the most energy-saving, followed by T5, and T8 was the last one. In the experiment on the effects of different spatial elements, the effects of the 3 experimental factors, namely “ceiling height”, “with or without partitions” and “office seat configuration”, on the lighting of office space were investigated. The study results showed that the ceiling height affected the overall average illumination. The higher the ceiling was, the lower the space illumination would be, and the lower the ceiling was, the higher the space illumination would be. After partitions were added to the seats, the space illumination decreased, which was improper for the space with high demand for illumination. There was no significant difference in the illumination distribution of office space and the lighting simulation results between the parallel configuration and the face-to-face configuration.
