This study is aimed at proposing an economic Cooling System by total area using Life Cycle Costing, a general economical efficiency analysis method considering total amount of investment, service life, salvage value and the change of price caused by interest rate or inflation. LCC elements of Cooling System are Initial costs, Operations costs, Maintenance costs, Replacement/Alteration costs, Tax costs, Salvage costs etc., and considerable factors are Discount or Interrest rate, Escalation, Service life etc. In order to compare design alternatives, both present and future costs for each alternative must be brought to a common point in time. Costs may be converted to today's cost by the present-worth method, or may be converted to an annual series of payments by the annualized method.

정순성,이정재 한국건축설비학회 1999 건축 설비 Vol.2 No.4

최근 건설교통부에서 2002년까지 공공사업비 20% 절감을 목표로 내세운 "공공 건설사업 효율화 종합 대책"이 지난 1999년 3월 13일에 확정·발표되었다. 이번 대책의 기획·설계 분야에서 생애주기비용 분석제도(LCC 분석) 도입으로 인하여 연내 건설기술관리법 시행령에 LCC 분석에 관한 근거규정이 신설되고, 내년까지 LCC 분석절차와 기법이 개발되어 오는 2000년부터 설계금액기준 500억원 이상 대형사업에 시범적으로 적용되며, 2002년부터는 공공사업전반에 확대·적용되어 장기적으로는 자재조달, 시공, 유지관리단계에도 LCC 분석 기법의 적용이 확대될 예정이므로 LCC 분석에 대하여 많은 사람들의 관심이 집중되고 있는 실정이다. 본 연구는 건축설비분야에서 생애주기비용 분석제도 도입시 LCC 분석절차 및 기법 개발을 위한 기초적인 연구로서, 국내 실정에 적합한 HVAC 시스템의 비용분류체계(Cost Breakdown Structure; CBS)를 구축하고자 한다. 본 연구에서는 HVAC 시스템의 비용분류체계로서 3단계의 수준을 가지는 비용분류체계로 구성하였으며, 기획·설계비, 초기투자비, 각종 지원금, 에너지비, 상·하수도비, 보전비, 일반관리비, 폐각비, 갱신비, 기타 비용 등 10가지로 대분류하고, 그 내에서 발생비용을 소분류하였으며, 비용분류체계의 특징은 B.S. Blanchard와 Fabrycky의 방법론에서 고려하지 않은 세금 및 보험료와 기존의 LCC 비용분류체계에서 전혀 언급이 없는 각종 지원금을 비용분류체계에 포함시겼다. HVAC 시스템의 LCC 비용분류체계 구축 표현 방법으로 각 비용분류체계 블록에 대한 적절한 수준, 제목, CBS 번호, 블록번호를 결정하였으며, 특히 비용분류체계에 각종 현가 계수를 첨가함으로서 현가법에 의한 LCC 비용분류체계를 더욱더 명확하게 할 수 있으므로 이러한 방법을 제안하였다. The purpose of this study is to suggest the criteria of cost breakdown structure of HVAC system for life cycle cost analysis. Results of research in cost breakdown structure that is one of the most important procedures in life cycle cost analysis are that; LCC cost breakdown structure in HVAC system, which have consideration for both characteristics of architectural equipment and domestic situations, is categorized with main classification systems such as plan design cost, initial investment cost, systematic support cost, energy cost, water service and drainage cost, maintenance cost, general management cost, salvage cost, replacement/alteration cost, and other costs, and lower level classifications on each are deduced from resonable data and factors. As for LCC cost breakdown structure in HVAC system, pertinent level, title, CBS number, and block number are determined efficiently. Especially, with addition to current cost factor, it is possible to make LCC cost breakdown structure using by present worth method more clear.
