Abstract

For several decades, economic growth has achieved in the aspect of productivity and effectiveness not environmental friendly. As a result, global warming is a major agenda to solve. Therefore, global effort to sustainable development has been adopted like UNFCCC and Kyoto protocol that aimed to reduce greenhouse gas. However, the construction industry has only focused on applying techniques for using less energy sources not monitoring sustainable construction and development. Therefore, this study developed a tool for monitoring greenhouse gas emissions in construction industry. The proposed system evaluates and estimates BAU (Business as usual) for each phase of a construction project. For this purpose, analyzed the greenhouse gas emission factors coincide to life cycle of a construction project. The scope of monitoring is determined according to data availability and emission factor. Then, the system framework is developed and the calculation logic is proposed the system features provide comparison between the emission estimates for eco-friendly design and the actual emission of construction and operation phases. The system would be utilized as a tool for supporting to green construction realization and green construction performance evaluation.

지난 수십 년간의 경제성장은 환경보다는 생산성과 효율성을 중시하며 진행되었다. 그 결과, 현재 전 세계는 인류의 생존을 위협하는 지구온난화라는 심각한 환경위기에 직면하게 되었다. 이에 따라 온실가스 감축과 지속가능한 발전을 위한 국제적 노력으로 '기후변화에 관한 UN협약(UNFCCC)'과 '교토의정서(Kyoto Protocol)'가 공식 발효되었다. 그러나 건설 산업의 노력은 에너지 저감 기술의 개발과 적용에 치중되어있다. 따라서 본 연구는 건설 산업의 온실 가스배출량을 모니터링 하기 위한 시스템을 개발하였다. 본 연구에서 제안한 모니터링 시스템은 온실가스 배출전망치와 실제배출치의 산정을 통해 단계별로 모니터링하고 이를 비교 평가한다. 이를 위해, 건설 프로젝트의 일반적인 생애주기에 따르는 온실가스 배출요인을 분석하였으며, 이를 설계도서 등 기초 데이터자료의 수집용이성, 배출계수의 구축여부를 기준으로 본 연구의 온실가스 모니터링 분석범위를 결정하였다. 또한, 사업단계별 배출량 산정방법의 구축을 통해 모니터링 시스템을 구축하였다. 본 연구의 모니터링 시스템은 설계시점에서 배출전망치 산정을 통한 친환경적인 의사결정과 실제 시공 및 운영시점에서 실제 배출치 산정을 통한 녹색건설현장 구현, 그리고 배출전망치와 실제 배출치 간의 비교 평가를 통한 녹색건설 성과평가 지원도구로 활용이 기대된다.
