Automatic Cx Tools
検討指示
・ Development and employmentof procedure
documents
・Development and employment of documentation
tools requisite at each phase
（ Commissioning planning documents determine
the framework of each phase of comissioning and,
thus, has significant importance.）
・ Development and employment of check-list
sheets with grades of items which require the
verification at each phase
・This BEMS treats operational data of heat sorce
systems, pumps systems (including heat storage
tunks), air-conditioning-units, and VAV systems.
・Automatic accumulation of data at intervals of 1
minute,10 minute and 1 hour
・Automatic real-time graphs of the data and the
part of calculated data which contribute to check
the every-day operational conditions and even
function performance tests.
・Coordination of the BEMS functions and forecast
estimation system of heat-storage
Practical experiences
Users interview
Occupant Interview
・mostly no troubles
Operator Interview
・up until now, no severe troubles
・heat storage operation has proceeded well.
Cx actions
・interview with the owner, designers and constructors.
・development and verification of documentation tools
・verification of construction conditions
・verification of TAB results
・execution of function performance tests
・operational data check assisted by BEMS
