Abstract

The reliability of the results of LCC analysis is determined by accurate analytical procedures and energy data from which the uncertainty is removed. Until now, systems that can automatically measure these energy data and produce databases have not been commercialized. Therefore this paper proposes a concept model of an S-LCC platform that can automatically collect and analyze electric energy consumption data of equipment systems using the IOT, which is the core tool in the Fourth Industrial Revolution and operates the equipment system efficiently using the analyzed results. The proposed concept model was developed by the convergence of existing BLCS and IOT and was comprised of five modules: Facility Control Module, LCC Analysis Module, Energy Consumption Control Module, Efficiency Analysis Module, and Maintenance Standard Reestablishment Module. Using the results of LCC analysis deduced from this system, the deterioration condition of an equipment system can be identified in real-time. The results can be used as the baseline data to re-establish standards for the maintenance factor, replacement frequency, and lifetime of existing equipment, and establish new maintenance standards for new equipment. If the S-LCC platform is established, it would increase the reliability of LCC analysis, reduce the labor force for entering data and improve accuracy, and would also change disregarded data into big data with high potential.

건축물의 LCC 분석 결과의 신뢰성은 정확한 분석 절차와 불확실성이 제거된 데이터에 의해서 결정된다. 그러나 지금까지는 이 데이터를 자동으로 계측하고 DB화 할 수 있는 시스템들이 실용화되지 못하였다. 이에 본 연구에서는 4차 산업혁명의 핵심도구인 IOT를 활용하여 설비시스템의 전기에너지 소모량 데이터를 자동으로 수집하여 분석하고, 분석된 결과들을 활용하여 설비시스템의 효율적 운전이 가능한 S-LCC 플랫폼의 개념모델을 제안하였다. 제안된 개념 모델은 기존의 유지관리 시스템(BLCS)에 IOT를 융합하여 모델링되었으며, 이것은 시설물관리모듈, LCC분석모듈, 에너지사용량 관리모듈, 상태효율분석모듈, 유지보수기준재설정모듈 등 5개의 세부 모듈로 구성되어야 업무프로세스가 효율화될 수 있다. 이 시스템에서 도출하는 LCC분석결과를 활용하여 설비시스템의 노후화 상태를 실시간으로 파악할 수 있으며, 또한 기존설비의 보수율과 교체주기, 수명 등에 관한 기준들을 재설정하고, 신규설비의 유지관리기준을 새롭게 설정하는 기초자료로 활용될 수 있다. S-LCC 플랫폼이 구축될 경우, LCC 분석의 신뢰성 증대, 자료입력을 위한 노동력 절감, 정확성 제고 등의 효과뿐만 아니라 지금까지 버려졌던 데이터를 잠재가치가 큰 빅 데이터로 바꿀 수 있다.
