Abstract

The seriousness of global warming is increasingly being recognized worldwide, and there is a growing need to precisely understand the impact of greenhouse gas emissions from the construction industry. Particularly, with increasing interest in Off-Site Construction (OSC) technology in the domestic construction sector, it has become urgent to assess the embodied carbon emissions of concrete structural products produced in factories, known for their high inherent carbon emissions, as concrete is one of the most widely used materials in the construction industry. In this study, the embodied carbon emissions of precast concrete (PC) which is a representative off-site construction structure, were calculated based on actual data of PC manufacturing factories. Data on inputs, processes, outputs were collected from five representative PC factories in Korea. The Life Cycle Assessment (LCA) methodology was used to calculate and analyze the embodied carbon impact of PC throughout its life cycle. The results of this study are expected to serve as fundamental data for establishing sustainable application methods for domestic OSC technology in the future.

전 세계적으로 지구온난화의 심각성이 대두되고 있으며, 건설 분야에서도 건설 산업에서 발생하는 지구온난화 영향을 더욱 정밀하게 파악할 필요가 있다. 특히, 건설 산업에서 가장 많이 사용되고 있는 콘크리트의 내재탄소 배출량이 매우 높은 것으로 알려진 가운데, 국내 건설분야에서 탈현장건설(OSC) 기술에 대한 관심이 증가함에 따라 공장에서 생산되는 콘크리트 구조 제품들의 내재탄소 배출량에 대한 파악이 시급해진 실정이다. 이에, 본 연구에서는 대표적인 탈현장건설 구조물인 구조용 프리캐스트 콘크리트(PC)에 대한 전과정 내재탄소 배출량을 실제 공장 데이터를 토대로 산정하였다. 이를 위해 한국의 대표적인 PC 생산공장 5곳의 투입물, 공정, 제품 및 부산물 등에 대한 현장 데이터를 수집했으며, 전과정평가(LCA) 방법론을 통해 PC의 전과정 내재탄소영향을 산정하고 분석하였다. 본 연구를 통해 도출된 결과는 향후 국내 OSC 기술의 지속가능한 적용 방법을 정립하는 데에 기초자료로써 널리 활용할 수 있을 것으로 기대된다.
