GreenTouch 光源控制器-節能觸控照明開關 辦公室使用電燈光源據統計耗費建築物19%的能源。如果自然光是充足的，則可以減少約幾乎 一半的能源。在自然光充足，足以照明環境時，電燈幾乎很少被轉小亮度或關掉，而在使用不 熟悉的電燈開關時使用者常常會開錯開關。因此，我們發展了可個人化預設的多點觸碰光源控 制板，他可用簡單手勢來控制燈光。控制板可以從全環境燈光控制下進行單一光源亮度的控制 ，所以每一個光源屬性可以先被預設。為了有效使用自然光，光源架是可以拿來抓取太陽光。 亮度將會自動減弱去以符合每個人的預設光需求，這個光源系統解決了使用者不方便性與能源 消耗問題，我們使用了台北的一個辦公室和模擬軟體分析系統效率而應用模擬將可以估計出潛 在的節能處，我們團隊也做了使用者測試，測試內容有(1)操作性(2)兩個傳統開關與MLC和 IMLC的操作速度與效果(3)在操作中觀察使用者視線位置，35名使用者測試下IMLC除了在控制 性排在第二外，其他在效果、對照資訊與裝置回應上分數最高，結果顯示系統並不只是節能也 達到使用者友善介面的目的，使用者比較想使用此裝置而非傳統開關，此裝置預估節省了有 20%原本要被消耗的能量。

Office lighting accounts for 19% of building energy consumption. If the daylight is well exploited, almost half of the energy consumption can be minimized. Lighting is rarely adjusted for intensity of luminaires or even turned off when the daylight is sufficient enough to illuminate the environment. We developed a multi-touch lighting control panel with individual presets, which can be controlled by simple gestures. The panel can distinguish single luminaire controls from the entire environment lighting control, so everyone’s lighting preference setting can be pre-set. To efficiently utilize the daylight, a light shelf is introduced to catch more sunlight. The luminaries will automatically dim to meet everyone’s pre-set lighting needs. This lighting system solves the problem of user inconvenience and daylight dissipation. We used an office space in Taipei, Taiwan to analyze the efficiency of the system, and a software simulation was used to estimate the potential energy saving. The results showed that the system is not only energy-saving but also user-friendly. Users prefer this system to the traditional rocker light switch. It is estimated that 20% artificial lighting energy consumption can be saved.
