摘要

本研究運用聚異丙基丙烯醯胺水膠，填裝於不同厚度的容器之內，並試著製作出具節能、採光效應之窗材。窗材經過受熱後溫度達到32℃會變不透明。像夏天外界溫度過高時，能阻擋多餘的熱能，當太陽直射時也能有足夠的採光，減少屋內能源的消耗。
在計算其不同厚度之節能窗材的節能效率後，選擇較佳的厚度模型，實際將材料填裝進玻璃模型中。
經過實驗之後，有添加節能材料的窗材，直接照射於60W燈泡下5小時，厚度分別為3mm、4mm、5mm與無添加節能材料的窗材，其模型屋內部空氣溫差約2℃~3.5℃，計算節能效率約39%~55%。而直接在陽光下照射3小時，有添加節能材料的窗材，厚度為5mm與無添加節能材料的窗材，其模型屋內部空氣溫差約達到8℃~15℃，計算節能效率約45%。
經過照度計量測之後，平均照度值約1000 Lux，比照CNS室內照度標準，適合從事寫作及縫紉等工作。
實驗證明此節能窗材是可以實際運用於屋頂採光罩或是屋內玻璃窗。

In this study, window panel filled in ploy (N-isopropylacrylamide) (PNIPAAm) with different thickness has been fabricated to explore the influence of energy saving and daylighting due to the effect of temperature variation. It is found that the window panel will become opaque when the temperature reaches over 32 ℃. Hence, this window panel can decrease the excess lighting and then reduce the heat penetration. In the hot summer, this window panel can reduce the energy consumption of air-conditioning system inside the house.
A model room with small scale has been used in the experiment. This study has calculated the energy saving efficiency of the energy-saving windows with different thickness of PNIPAAm which include 3mm, 4mm and 5mm.
In the experiment, when the window panel is illuminated under the 60W light bulb for 5 hours, the temperature comparison between the glass panel with PNIPAAm and the glass panel without PNIPAAm in the model room is approximately 2℃ to 3.5℃. And the corresponding energy saving efficiency is approximately 39% to 55%.
When the window panel is exposed under the sunlight for 3 hours, the temperature comparison between the glass panel with PNIPAAm and the glass panel without PNIPAAm in the model room is approximately 8℃ to 15℃. And the corresponding energy saving efficiency is approximately 45%. As to the illumination inside the glass panel with PNIPAAm, the average scale of illumination meter is approximately 1000 Lux. According to the CNS indoor lighting standard, this scale is still suitable to be engaged on writing or tailoring.
Therefore, this study shows that the glass panel filled with PNIPAAm can be applied on the roof or the windows for the purpose of energy saving while still keeping enough daylight.
