에너지 절감 및 경제성을 고려한 생활관 리모델링의 적정 주기에 관한 연구

This study aims at proposing an optimal remodeling cycle in the light of economic feasibility consequent on the payback cycle of investment cost in energy performance improvement of a military barracks facing a maintenance cycle, and cost-saving effect. On the basis of the result of the preceding research which analyzed the energy requirement of a military barracks by the year of completion, this study analyzed the economic feasibility of a military barracks by selecting the energy remodelling plan, and cost analysis condition. The analysis result revealed that cost-benefits occurred after the elapse of 1.8 year to 7.5 years marking the regional payback cycle of investment cost in case of concurrent implementation of energy remodeling which serves to reinforce the heat insulation layer, and to improve window performance in doing repair work by part on a military barracks, which was built in the early 2000s, facing a maintenance cycle of roof waterproofing-finishing materials-window. On the contrary, in case of failure to do concurrent implementation of energy remodeling, it was analyzed that cost-benefits occurred after the elapse of 9.2 years to 20 years.
