Abstract

Recently, in an attempt to overcome the defects of quiescent power shutdown system, smart quiescent power control system has been developed. However, due to its higher investment costs, feasibility evaluation must be conducted. While LCCA (Life Cycle Cost Analysis) model is useful to estimate net savings of alternatives that differ with respect to initial costs and operating costs, the environmental burdens are not considered. On the contrary, LCA (Life Cycle Assessment) model is suitable to assess environmental impacts associated with the stages of a product's life but it does not consider costs. In this study, a comprehensive analysis on the economic and environmental impacts of smart quiescent power control system is conducted by using LCCA and LCA model. In addition, sensitivity analysis is carried out to quantify accuracy of estimates.

기존의 대기전력차단시스템의 단점을 극복하고자 최근 지능형 대기전력 제어시스템이 개발되기에 이르렀다. 하지만 기존의 시스템 보다 투자금액이 높은 문제로 도입에 대한 타당성 검토가 필요하다. 이에 본 연구에서는 LCCA 및 LCA를 이용하여 경제적 측면 및 환경적 측면을 종합적으로 분석하여 도입의 타당성을 검토하였다. 또한 결과의 신뢰성을 확보하기 위하여 민감도 분석을 실시하였다.
