Abstract

Tunnel is the most energy-consuming structure in road due to the characteristic of using artificial lighting during day and night. Therefore, tunnel lights are being replaced by LED lamp that have advantages with respect to low power consumption. The best use of social overhead capital can be expected by considering the life cycle cost, because to tunnel structures are accompanied by a series of medium-to-long-term and continuous processes of replacing auxiliary facilities. In this study, the saving effect by LCC analysis was quantitatively analyzed by replacing tunnel light sources from high-pressure sodium lamps to LED lamps. The effect of reducing the replacement cycle by increasing the life of the lamps and the resulting maintenance cost is very significant, on replacing tunnel lighting light sources with LED lamp.

Life cycle cost

터널은 주 ‧ 야간 모두 인공조명을 사용해야 되는 특성으로 인해 에너지 소비가 가장 많이 발생하는 도로 공간으로, 전기요금 절감 등을 위해 기존 터널조명 광원 대비 낮은 소비전력, 장수명의 장점을 갖는 LED램프로 교체 중에 있다. 터널구조물은 공용 중 부속시설 교체라는 일련의 중장기적이고 지속적인 과정이 수반되므로, 시설물 공용기간 동안의 생애주기비용을 고려해야 사회간접자본의 효율적인 활용을 기대할 수 있다. 따라서 본 연구에서 터널 조명광원을 고압나트륨램프에서 LED램프로 교체 시 LCC측면의 절감효과를 정량적으로 분석하였으며, 터널 조명 광원을 LED램프로 교체 시 램프의 수명증대에 의한 교체주기 감소 및 이로 인한 유지관리 비용 감소효과가 매우 큰 것으로 나타났다.
