基於BIM的方法評估台灣基於碳排放評估的改造效果

Abstract

面對氣候變遷和可持續發展的迫切需求，建築行業在全球碳排放中扮演著重要的角色，特別是在台灣這樣一個預計受氣候變遷影響嚴重的地區。能源改造已經成為改善建築物能源消耗的有希望的解決方案，而建築信息模型（BIM）在促進改造項目的初期階段顯示出巨大潛力。然而，在特別是在像台灣這樣具有潮濕亞熱帶氣候，冷卻需求相當大的地區，仍然缺乏特定設計用於量化與建築物改造相關的碳排放的BIM方法。本研究旨在彌補這一空缺，提出了一個適用於類似改造項目的綜合BIM框架。該框架提供了一個概述指南，提供了一個邏輯和有效的方法來實施所提出的方法論。該框架的效果通過一個包含多種改造選項的實際案例研究進行評估。本研究的結果不僅突顯了BIM在台灣改造項目中的潛力，而且為未來的研究工作做出了貢獻，旨在全面評估改造項目在整個項目生命周期中的多方面收益。通過開發和應用所提出的框架，本研究有助於推進可持續建築實踐，並為參與改造項目的相關利益相關者提供有價值的見解。BIM和碳排放量化的整合可以增強決策過程，使改造策略的評估更加準確，並有助於減少建築環境中的總碳排放量。

In the face of climate change and the imperative for sustainable development, the building sector plays a significant role in global carbon emissions, especially in Taiwan, the region is forecasted to be heavily affected by climate change. Energy retrofitting has emerged as a promising solution to improve energy consumption in buildings, and Building Information Modeling (BIM) has shown great potential in facilitating retrofitting projects during the early stages. However, there remains a lack of BIM methodologies specifically designed to quantify the carbon emissions associated with building retrofits, particularly in regions with humid subtropical climates like Taiwan, where cooling demands are substantial. This research aims to address this gap by proposing a comprehensive BIM-based framework tailored to similar retrofit projects. The framework provides an overview guideline that offers a logical and effective approach for implementing the proposed methodology. The effectiveness of the framework is evaluated through a real-world case study that encompasses various retrofitting options. The results of this study not only highlight the potential of BIM in retrofitting projects in Taiwan but also contribute to future investigations that aim to comprehensively assess the multifaceted benefits of retrofitting over the entire lifecycle of a project. By developing and applying the proposed framework, this research contributes to the advancement of sustainable building practices and provides valuable insights for stakeholders involved in retrofitting projects. The integration of BIM and carbon emissions quantification can enhance decision-making processes, enable more accurate assessments of retrofitting strategies, and contribute to the overall reduction of carbon emissions in the built environment.
