Commissioning is a quality-oriented process for achieving, verifying and documenting whether the performance of a building's systems and assemblies meet defined objectives and criteria. Among four types of commissioning, ongoing commissioning is a commissioning process conducted continually for the purpose of maintaining, improving and optimizing the performance of building systems initial or re/retro commissioning. Ongoing commissioning maintains the optimal status of a building and gives financial, comfort and performance benefits to the building's owner, staff and future occupants. We need to develop an ICT-based building ongoing commissioning system. In this paper, we show our developed ICT-based building ongoing commissioning system for the first time in Korea. And we explain our Open gateway system, Ongoing commissioning control center system, Building energy ongoing performance diagnosis and management system, Building energy consumption information statistical analysis system, and a testbed of the ETRI 12th building. Finally we describe our implementation result.
