工業革命製造了大量溫室氣體排放，極端氣候已逐漸對人類的生存造成威脅。因應氣候變遷，聯合國於巴黎氣候協定提出了淨零碳排的目標，國際能源總署更指出全球碳排放量一年裡有37％是來自於建築部門。台灣為達成淨零碳排的目標，於2022年時提出了「臺灣2050淨零排放路徑及策略總說明」，並將提升建築外殼列為重要目標。

除了被動減碳技術，建築主動調控策略亦逐漸受到重視。相變材料(Phase Change Materials, PCM)應用於建築外殼，具備良好的熱儲存與釋放能力，可有效調節室內溫度，降低建築能耗。然而，相變材料的適用性受限於地區的溫差，因此設計策略需因地制宜。

本研究擬定台灣部分地區做為實驗地點，以Autodesk平台之Revit 及Insight模擬數據：透過Revit建模設定，設計實驗模型並導入相變材料參數，針對不同地去進行位置改變，隨後輸出至建築能耗模擬軟體-Insight進行雲端模擬，達到BIM結合BEM之整合應用，並基於營運碳排放量及能源使用強度得知相變材料對於建築之影響，分析相變材料用於建築之潛力及可行性，探討其在台灣不同區域之應用潛力與實務之可行性，盼提供未來建築設計之參考。

Since the Industrial Revolution, the massive emission of greenhouse gases has led to increasingly severe extreme weather events, posing a growing threat to human survival. In response to climate change, the United Nations introduced the goal of net-zero carbon emissions under the Paris Agreement. The International Energy Agency has reported that approximately 37% of global annual carbon emissions originate from the building sector. To align with this international goal, Taiwan released the "Taiwan 2050 Net-Zero Emissions Pathway and Strategy Overview" in 2022, identifying the enhancement of building envelope performance as one of its key strategies.

In addition to passive carbon reduction technologies, active regulation strategies in buildings have attracted increasing attention. Among them, the integration of Phase Change Materials (PCMs) into building envelopes is recognized for its capacity to store and release thermal energy, thereby stabilizing indoor temperatures and reducing overall energy consumption. However, the effectiveness of PCMs can vary significantly with regional climate conditions, necessitating climate-responsive design strategies.

This study selects various locations in Taiwan as experimental sites to assess the effectiveness of PCMs. Using Autodesk's Revit and Insight platforms, building models were created in Revit with integrated PCM parameters and subjected to location-based modifications. These models were then imported into Insight for cloud-based simulation, realizing a combined application of Building Information Modeling (BIM) and Building Energy Modeling (BEM). The simulation results, evaluated through operational carbon emissions and Energy Use Intensity (EUI), provide insights into the impact of PCMs on building energy performance. The findings help explore the applicability and feasibility of PCM integration in different climatic zones of Taiwan and offer practical reference for future architectural design and sustainable building strategies.
