“…또한 기존의 LCCA 연구들은 단순 비용절감 측면의 경제성 분 석에 치우쳐 있어 에너지소비에 따른 환경비용을 고려하 지 않은 한계가 있다 [7,8,9]. 이러한 환경적 영향을 분석 하기 위한 방법으로는 LCA(Life Cycle Assessment; 이 하 LCA)가 있지만, LCA만 평가할 경우 비교대상간의 환 경영향에 대한 상호우위만 분석될 뿐 경제적인 평가는 분 석되기 어려운 점이 있다 [8,9,10].…”

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.
