| 摘要: | 由於人類的過度建設開發導致地球環境嚴重惡化，溫室效應逐年擴增的結果導致全球氣候變遷，自十八世紀工業革命以來，人類大量使用石化能源以創造經濟高速成長，反而造成大氣中的溫室氣體濃度大幅提高，以致於氣溫升高及氣候型態改變。根據 IPCC在2007年11月正式發布的第四次評估報告內容中表示全球暖化與極端氣候源於人類行為累積的後果，此結果將導致數十億人面臨 逐步嚴重的缺糧、缺水和洪水泛濫。
本研究係以台中某商場建物由常見的鋼筋混凝土構造施工建案改成以預鑄工法施工為例，藉由建築物的生命週期評估LCA（Life Cycle Assessment）架構中，以企業到企業(B to B)範疇，從材料取得階段、生產製造階段、成品運輸階段等過程的碳排放盤查評估，亦即從建築物的「搖籃到客戶」進行系統性的碳排放盤查影響評估，導入預鑄建築工法在二氧化碳排放影響方面進行評估分析。
針對以預鑄工法建造建築物時，依據ISO 14040系列規範，將預鑄構件以生命週期之各個階段設定範疇，進行預鑄構件產品PCR之二氧化碳排放量盤查，參考ISO 14064-1與環保署碳足跡估算模式，在產業中進行二氧化碳排放評估與二氧化碳減量之對策探討。此外，本研究分析碳排係數數據以經濟部能源局公告106年電力與燃料排放係數及實際原料廠商公佈碳排係數當量數值進行評估預鑄構件生命週期 CO2 之評估。
結果分析可提供建築規劃從業人員在建築設計階段進行減碳作業，亦可估算預鑄工法建築物對地球環境之衝擊程度，進而將評估結果反饋至建築設計上，以提供設計者進行綠建築與低環境衝擊，亦可提供相似產業特性的預拌混凝土廠評估產品生命週期 CO2 之評估建模與碳足跡宣告之參考。;Due to the excessive construction and development of human beings, the global environment has become severely degraded. With the expansion of the greenhouse effect, the result is a global climate change.Since the industrial revolution in the eighteenth century, humans have use petrochemical energy in large quantities to create rapid economic growth, the concentration of greenhouse gases in the atmosphere has increased dramatically, as a result, temperatures have risen and climate patterns have changed.
According to the fourth assessment report officially released by the IPCC in November 2007, the content indicates that global warming and extreme climate are the results of the accumulation of human behavior, the result will cause billions of people gradually severe food shortages, water scarcity, and flooding.
This research is based on the construction of a ommon reinforced concrete structure in a shopping mall in Taichung, in the life cycle assessment (LCA) of the building, in the business to business category, carbon emission assessment from the material acquisition stage, production stage, and finished product transportation stage.That is a systematic carbon emission impact assessment from the "cradle to customer" of the building, importing precast construction method to evaluate and analyze the impact of carbon dioxide emissions.
When building a construction using precast method, in according with the ISO 14040 series of specifications, precast components at each stage of the life cycle should set a scope, carry out an CO2 emissions inventory of the precast concrete products, and refer to ISO 14064-1 and the EPA′s carbon footprint estimation model, conduct a carbon dioxide emissions assessment and carbon dioxide reduction measures in the industry.In addition, this study analyzes the Energy Bureau of the Ministry of Economic Affairs power and fuel emission factors announced in 2017, and material manufacturer announced carbon coefficient equivalent value, to assess the life cycle of carbon dioxide in the precast component part.
The results analysis can provide construction planning practitioners to reduce carbon in the architectural design stage,and can also possible to estimate the impact of the construction method on the global environment, then feedback the evaluation results to the architectural design.
To provide designers with buildings and low environmental impact, it can also provide ready-mixed concrete plants with similar industrial characteristics to evaluate the product life cycle CO2 assessment modeling and carbon footprint announcement.
Keywords: Life Cycle Assessment, Carbon Dioxide Emissions, Construction Method. |
