Abstract

Multi-household buildings are efficiently maintained from the mid- and long-term viewpoint according to the long-term repair coverage system etc. On the other hand, public buildings are not systematically maintained due to a lack of past maintenance cost data and inefficient budget plans, among other problems. Targeting public buildings in Incheon, this study analyzed operation costs variables. To verify the analysis results, they underwent a correlation analysis and a multi-regression analysis. With regard to public buildings electricity, gas and tap water cost, the influence power of the served life, floor area, and workforce were analyzed, revealing that electricity cost was highly correlated with workforce, while gas and tap water cost were correlated with tap water cost. Also, the correlation analysis results were verified through a multi-regression analysis, and a maintenance cost estimation model was presented using a regression equation.

공동주택은 장기수선충당금제도 등에 따라 중 장기적인 관점에서 효율적인 유지관리가 수행되고 있는 반면, 공공청사는 과거 유지관리비 실적자료 부족과 비효율적인 예산산정 등의 문제로 인해 유지관리가 체계적으로 이루어지지 않고 있다. 본 연구에서는 인천지역의 공공청사를 대상으로 운영비의 영향요인을 분석하고, 이를 검증하기 위해 상관관계 분석 및 다중회귀 분석을 실시하였다. 공공청사의 전기, 가스, 수도요금에 대한 경과년수, 연면적, 직원 수의 영향력을 분석한 결과, 전기요금은 직원 수와 높은 상관성을 보였으며 가스, 수도요금은 연면적과 상관성이 있는 것으로 나타났다. 다중회귀 분석을 통해 상관관계 분석결과를 검증하였으며, 회귀 방정식을 통해 운영비용의 추정모형을 제시하였다.
