近年來，地球極端氣候事件頻率和嚴重程度不斷加劇，對人類生活和環境造成嚴重影響。全球各國積極推動減碳行動，要求各行各業落實淨零轉型，其中營造產業被視為重點減碳對象。營造產業作為能源消耗和碳排放的主要來源之一，碳排放問題日益嚴峻。因此，加強建築物在其整個生命週期中的節能減碳技術勢在必行。本研究通過整理文獻，彙整出幫助營造廠加強減碳方式的構面與要素，主構面分別是材料因素、運輸因素、工法因素、管理因素並細分出十五項評估要素，並請相關從業人員填寫問卷，利用層級分析法（AHP）對各主構面與要素進行比較，計算各項權重及全面性權重大小，並對排序結果進行分析。研究計算得出的結果由大到小排序為「材料因素（0.346）」、「工法因素（0.238）」、「運輸因素（0.224）」、「管理因素（0.192）」，而評估要素的前五名分別是「採用本地材料（0.111）」、「採用低能耗低碳材料（0.106）」、「降低排放汙染（0.085）」、「優化運輸距離（0.084）」、「採用低碳工法（0.071）」。根據上述結果顯示，四大構面在減碳策略中的重要性有所不同，但每個構面內的策略要素均對實現減碳目標具有關鍵作用。未來在制定和實施減碳策略時，需綜合考慮各構面的不同影響，以提升減碳效益。

In recent years, the frequency and severity of extreme climate events on Earth have continued to intensify, causing serious impacts on human life and the environment. Countries around the world are actively promoting carbon reduction actions and requiring all industries to implement net-zero transformation, among which the construction industry is regarded as a key carbon reduction target. The construction industry is one of the main sources of energy consumption and carbon emissions, and the problem of carbon emissions is becoming increasingly serious. Therefore, it is imperative to strengthen energy-saving and carbon-reduction technologies for buildings throughout their life cycle. By sorting out the literature, this study compiled the aspects and elements that help construction plants strengthen their carbon reduction methods. The main aspects are material factors, transportation factors, construction method factors, and management factors, and were subdivided into fifteen evaluation factors, and asked Relevant practitioners filled out questionnaires, used the Analytical Hierarchy Process (AHP) to compare the main aspects and elements, calculated the weights of each item and the comprehensive weight, and analyzed the ranking results. The results calculated by the study are ranked from large to small as "material factors (0.346)", "construction method factors (0.238)", "transportation factors (0.224)", and "management factors (0.192)", and the top five evaluation factors The names are "Use local materials (0.111)", "Use low energy consumption and low carbon materials (0.106)", "Reduce emission pollution (0.085)", "Optimize transportation distance (0.084)", "Use low carbon construction methods (0.071)" ". According to the above results, the importance of the four major aspects in the carbon reduction strategy is different, but the strategic elements within each aspect play a key role in achieving the carbon reduction goal. When formulating and implementing carbon reduction strategies in the future, the different impacts of each aspect need to be comprehensively considered to improve carbon reduction benefits.
