摘要:	年來，隨著全球暖化效應加劇，氣候變遷成為國際上共同面臨的重大挑戰。根據聯合國政府間氣候變遷專門委員會（Intergovernmental Panel on Climate Change, IPCC）第六次評估綜合報告（Sixth Assessment Report, AR6）指出，人類活動是二氧化碳排放的主要原因之一，為解決氣候變遷問題，淨零碳排放成為關鍵要素之一。然而，IPCC也指出，土地使用的改變會增加二氧化碳的排放量，進而影響氣候變化（IPCC, 2022）。以都市發展為例，早期建築物大多為磚造矮房或建築空地，其二氧化碳排放量較低。然而，隨著都市變遷與更新，這些建築物可能被高容積或鋼筋混凝土等高二氧化碳排放量的建築物取而代之。因此，都市地區更新前後的二氧化碳排放量可能存在差異，並且對於都市永續發展以及應對氣候變遷影響甚鉅。故本研究從土地使用深究建築物與開放空間之法定容積對二氧化碳排放量的減緩效果，在都市更新過程中，除關注建築物的二氧化碳排放量之外，還應考慮如何透過增加開放空間碳匯或再生建材實現碳中和，開放空間碳匯包括土地中的植被、土壤等，而再生能源則包括綠建築以及太陽能板，皆可以吸收及減少大量的二氧化碳，對於減緩氣候變遷具有重要作用。本研究以臺北市萬華區為例，首先計算區內現況原容積建築物的二氧化碳排放量，並以法定容積為基準推估更新後建築物的二氧化碳排放量，進而比較更新前後排放量的變化，最後結合開放空間的碳匯設計，以期達到碳中和的目標。研究結果顯示，更新前的建築結構大多為磚造及RC構造建築，且多數未達法定容積率與建蔽率；而更新後，根據法規計算樓高與地下樓層，假設建築物結構均為RC 構造，導致二氧化碳排放量顯著增加。為緩解更新後增加的二氧化碳排放，本研究導入綠建築理念，透過使用再生建材、增加太陽能板應用以及適當規劃開放空間碳匯等方式，進一步降低二氧化碳排放。開放空間碳匯結合鋪面材料碳排放、黃碳儲存與綠碳儲存的分析，展現顯著的減碳效益。同時，設計一套碳排放計算工具，快速評估不同情境下的二氧化碳排放量及減碳效益，為都市規劃者與決策者提供數據支援。透過研究建築與碳排放的相互影響，並提出實質的減碳策略，本研究為都市永續發展提供強力的依據，有效應對氣候變遷的挑戰，實現都市碳中和的目標。 In recent years, as the effects of global warming have intensified, climate change has become a major challenge faced by the international community. According to the Sixth Assessment Report (AR6) of the United Nations Intergovernmental Panel on Climate Change (IPCC), human activities are one of the main causes of carbon dioxide emissions. To solve the problem of climate change, net Zero carbon emissions become one of the key elements. However, the IPCC also points out that changes in land use will increase carbon dioxide emissions, thereby affecting climate change (IPCC, 2022). Take urban development as an example. Most of the early buildings were brick low-rise buildings or empty construction sites, which had low carbon dioxide emissions. However, with urban changes and renewal, these buildings may be replaced by high-volume or reinforced concrete buildings with high carbon dioxide emissions. Therefore, there may be differences in carbon dioxide emissions before and after urban area renewal, which will have a huge impact on urban sustainable development and response to climate change. Therefore, this study studies the mitigation effect of the legal volume of buildings and open spaces on carbon dioxide emissions from the perspective of land use. In the process of urban renewal, in addition to paying attention to the carbon dioxide emissions of buildings, we should also consider how to increase the carbon dioxide emissions of open spaces. Carbon sinks or recycled building materials can achieve carbon neutrality. Open space carbon sinks include vegetation and soil in the land, while renewable energy sources include green buildings and solar panels, which can absorb and reduce large amounts of carbon dioxide and play an important role in mitigating climate change. This study takes Wanhua District in Taipei City as an example. It first calculates the carbon dioxide emissions of the existing buildings in the district, estimates the carbon dioxide emissions of the buildings after the renovation based on the legal volume, and then compares the changes in emissions before and after the renovation. Finally, combined with the carbon sink design of the open space, we hope to achieve the goal of carbon neutrality. Research results show that most of the building structures before the update were brick and RC structures, and most of them did not meet the legal floor area ratio and built-up coverage ratio; after the update, the building height and underground floors were calculated according to regulations, assuming that the building structures were all RC structures. leading to a significant increase in carbon dioxide emissions. In order to alleviate the increased carbon dioxide emissions after renovation, this study introduced the concept of green building to further reduce carbon dioxide emissions by using recycled building materials, increasing the application of solar panels, and appropriately planning open space carbon sinks. The open space carbon sink combines the analysis of carbon emissions, yellow carbon storage and green carbon storage of paving materials to demonstrate significant carbon reduction benefits. At the same time, an operational Excel tool is designed to quickly assess carbon dioxide emissions and carbon reduction benefits under different scenarios, providing data support for urban planners and decision-makers. By studying the interaction between buildings and carbon emissions and proposing substantial carbon reduction strategies, this study provides a strong basis for sustainable urban development, effectively responds to the challenges of climate change, and achieves the goal of urban carbon neutrality.
