| dc.description.abstract | 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.
