요약문

녹색건축인증(G-SEED) 개정 이래, 전과정평가(Life Cycle Assessment-LCA)에 기반한 환경성적표지인증(Environmental Product Declaration–EPD)를 획득한 건축자재를 사용하는 경우 가점을 부여함에 따라 건축자재의 EPD가 급격하게 증가되었다. 특히, 레디믹스트 콘크리트(RMC-레미콘)의 EPD 누적건수는 2018년 18건 2019년 109건 2020년 501건 2021년 809건으로 매년 증가하고 있다. 본 연구에서는 현재 EPD 결과의 신뢰도를 높이기 위해 EPD에서 규정하고 있는 레미콘의 환경성적표지 개별지침을 분석하여 레미콘 환경성적표지인증의 개선안을 제시하고자 한다. PCR 분석 결과로는 공정수의 할당방법의 세분화 필요성이 있었고, 개별공장의 배출량 산정의 표기의 필요성이 있었다. 이러한 레미콘 PCR 분석을 통해서 추후 EPD의 일반제품 작성지침, 건축자재 작성지침, 레미콘 작성 지침 개정에 검토자료로 활용될 것으로 사료된다.

Since the revision of the Green Standard for Energy and Environmental Design (G-SEED), Environmental Product Declaration (EPD) of building materials has increased rapidly as additional points have been given to use building materials that have obtained EPD based on Life Cycle Assessment (LCA). In particular, the cumulative number of (Environmental Product Declaration–EPD) of ready-mixed concrete (RMC) is increasing every year from 18 in 2018, 109 in 2019, 501 in 2020, and 809 in 2021. In order to increase the reliability of the current EPD results, this study aims to present an improvement plan for the certification of EPD of RMC by analyzing the RMC Product Category Rules (PCR) as stipulated by the EPD. As a result of PCR analysis, there was a need to subdivide the method of allocating the number of processes, and there was a need to indicate the calculation of emissions of individual factories. Through this RMC PCR analysis, it is expected to be used as a review data for revising EPD's general product preparation guidelines, building material preparation guidelines, and remicon preparation guidelines in the future.
