摘要

因應世界永續及環保意識潮流，教育部自2006年起推廣「永續校園局部改造計畫」補助。林憲德(2003)曾指出，為了解決頂層空間的能源與居住環境之問題，最好的方法莫過於屋頂隔熱對策，因為屋頂隔熱可有效阻礙熱源的產生，能影響室內環境舒適與空調耗能之多寡，由此可見屋頂隔熱對於室內環境改善之重要性。
本研究為探討「永續校園局部改造計畫」項目之屋頂隔熱設施改造後的隔熱效益，以臺中市三所學校、共四處屋頂隔熱設施為樣本，藉由實地實測法進行短期連續實測，並將所測得之數據，經由描述性統計及利用統計軟體 SPSS 之獨立樣本 t 檢定，進行數據分析。研究結論如下：
一、有改造屋頂隔熱設施者，包括屋頂花園及鋁鋅鋼浪板兩種隔熱型式，改造為屋頂花園隔熱型式者，則具有屋頂表面降溫效果；但改造為鋁鋅鋼浪板隔熱型式者，其屋頂表面溫度反而高於無改造屋頂隔熱設施者。
二、有改造屋頂隔熱設施者，包括屋頂花園及鋁鋅鋼浪板兩種隔熱型式，對於頂層天花板表面溫度皆具有顯著之降溫效果。
三、有改造屋頂隔熱設施者，包括屋頂花園及鋁鋅鋼浪板兩種隔熱型式，對於頂層室內溫度皆具有顯著之降溫效果。
四、有無改造屋頂隔熱設施之隔熱效益，採實驗組與對照組比較，結果屋頂表面及頂層天花板以朝陽科大樣本降溫最多；頂層室內溫度以爽文國中樣本降溫最多。
五、各樣本之實驗組頂層室內平均溫度皆低於外氣溫度，顯示於既有建築屋頂上改造屋頂隔熱設施，能達到頂層降溫效果。

In response to the global trends of sustainability and environmental awareness, the Ministry of Education has started the promotion of grants for “Taiwan Sustainable Campus Project” in 2006. Lin (2003) pointed out that the best solution to the energy and living space problem of top floor of the building is roof insulation as it can effectively prevent the generation of heat and thus affecting the comfort of indoor environment and air conditioning power consumption. The significance of roof insulation to the improvement of indoor environment is apparent.
To discuss the heat insulation efficiency after the renovation of the roof insulation of “Taiwan Sustainable Campus Project”, this study sampled 4 roof insulation structures in three schools of Taichung City. Short term continuous measurement was conducted on the site by applying the on-site measurement method. The measurement data were analyzed using SPSS software for descriptive statistics and independent sample t-test. The research conclusions are as follow:
1. The structure of roof insulation can be divided into two types, including roof garden and aluminum-zinc corrugated steel. The insulation with roof garden has the roof surface cooling effect. However, the roof surface temperature of the building with aluminum-zinc corrugated steel insulation is even higher than the house without roof insulation.
2. The structure of roof insulation can be divided into two types including roof garden and aluminum-zinc corrugated steel. Both types of insulation have a significant cooling effect on top floor’s roof surface temperature.
3. The structure of roof insulation can be divided into two types including roof garden and aluminum-zinc corrugated steel. Both types of insulation have a significant cooling effect on top floor’s indoor temperature.
4. Regarding heat insulation efficiency of having or having no roof insulation, this study conducted a comparative study of the experimental group and the control group, and found that the cooling effect of roof surface and top floor ceiling is the best in the case of Chaoyang University of Technology and the cooling effect of top floor indoor temperature is the best in the case of Shuangwen High School.
5. Compared with the average outside air temperature, the top floor indoor average temperatures of the experimental groups of various samples are all lower than the outside air temperature, indicating the roof insulation on the rooftop of the building can achieve the cooling effect of the top floor.
