建築外殼隔熱性能是整體建築耗能的重要因素，我們常以熱傳透率(U值)
作為最主要的評估依據；然而在評估理論隔熱性能時，常因數據來源上的不一
致或施工過程的不確定性等各種因素，導致構造體隔熱性能之理論值與實際值
不符的情況產生。

隨著技術與學術的發展，構造隔熱性能之現地測量法也逐漸受到關注，過
去我們常根據國際標準ISO 9869的表面溫度法來定義建築構造之隔熱性能，近
年來構造隔熱性能之現地測量法在國際上逐漸多樣化，有更多新興方法被提
出；然而在台灣，隔熱性能之現地測量法卻不常被提及使用，除了學術研究單
位外，甚至沒有其他單位作實際應用操作。因此本研究旨在實驗不同方法，用
以瞭解相關測量參數之變化情形，並探討不同方法間的相對準確度，以利日後
可以針對不同情況選擇適合的現地測量方法。

本研究針對建築構造隔熱性能之現地測量法進行探討，主要以ISO 9869 之
表面溫度法、空氣表面溫度比法(ASTR)及定量紅外線熱影像測量法(IRT)共三種
現地測量法為基礎進行實驗，並選擇以教室內輕隔間作為實驗標的，來分析各
項參數的逐時變化趨勢及對各方法評估結果進行相對偏差率的比較。

The thermal insulation performance of the building shell is an important factor in
the overall energy consumption of the building. We often use the overall heat transfer coefficient (U value) as the main evaluation basis; however, when evaluating the theoretical thermal insulation performance, it is often due to inconsistencies in data sources or construction Various factors, such as the uncertainty of the process, cause the theoretical value of the thermal insulation performance of the structure to be inconsistent with the actual value.

With the development of technology and academics, the on-site measurement method of thermal insulation performance has gradually attracted attention. In the past, we often defined the thermal insulation performance of building construction
according to the international standard ISO 9869. In recent years, in-situ measurement methods for structural thermal insulation performance have gradually diversified internationally, and more emerging methods have been proposed.; however, in Taiwan, the on-site measurement method of thermal insulation performance is not
often mentioned and used. Apart from academic research units, there is even no other
unit for practical application operations. Therefore, the purpose of this research is to experiment with different methods to understand the changes of related measurement
parameters, and to explore the relative accuracy of different methods, so that you can choose suitable on-site measurement methods for different situations in the future.

This research discusses the in-situ measurement method for the thermal insulation performance of building structures. The experiments are based on three insitu
measurement methods including ISO 9869 surface temperature method, air surface temperature ratio method (ASTR) and quantitative infrared thermal imaging
measurement method (IRT). And choose the compartment in the classroom as the
experiment target to analyze the time-to-time change trend of various parameters and
compare the relative deviation rate of the evaluation results of each metho.
