Commissioning: "Commissioning (Cx) is a systematic quality assurance process of ensuring that building systems perform interactively according to the design intent and the owner's operational needs. It is a process for achieving, verifying, and documenting the performance of each system to meet the operational needs of the building within the capabilities of the documented design and specified equipment capacities, according to the owner's functional criteria. It is process that ensures the quality of the installation."
"Commissioning consists of systematically documenting that specified components and systems have been installed and started up properly, and then functionally tested to verify and document proper operation through all modes and conditions. In addition, owner-personnel training will be verified and final project operations and maintenance (O&M) documents will be reviewed for completeness." The following phases can be provided:
1. Program Phase2. Design Phase
3. Construction Phase
4. Acceptance Phase
5. Post Acceptance Phase
| BENEFITS OF COMMISSIONING • Ensure system achieves maximum energy efficiency • Coordinates construction and scheduling • Corrects uncovered construction deficiencies • Provides for faster problem resolution • Minimizes operating costs • Provides detailed facilities training for operating staff • O & M manual documentation of systems • Provides a historical record of the design background • Provides an independent advocate for the Owner during construction |
COMMISSIONING DURING DESIGN PHASE
. Meeting w/ design firm to coordinate commissioning functions
. Assists in documentation of design basis and intent . Provides samples and templates of forms to be used by the engineer . Determine systems to be commissioned . Review, document, and add energy efficiency measures and critical requirements to design . Design review and Letter of Review analysis . Assist in construction specification development as applicable to commissioning systems . Begin developing commissioning plan . Begin development of pre-functional and functional test procedures . Begin development of O & M manual |
COMMISSIONING DURING CONSTRUCTION PHASE
. Update schedule
. Execute and coordinate a commissioning meeting at start of project to brief all contract parties on the function of commissioning, the process, and roles & responsibilities . Develop contact list (OEM reps, controls contractors, etc) . Finalize PFT (pre-functional test ) and FT (functional test) procedures w/ manufacturer submittal data ( Start up procedures and punch list requirements ) . Perform prefunctional tests - document deficiencies and schedule retest after corrective action . Perform functional tests - document deficiencies and schedule retest after corrective action . Detail training contacts and training plan . Issue certificate of readiness |
COMMISSIONING DURING ACCEPTANCE PHASE
. Coordinate / Perform Operator Training
. Complete the Commissioning Report . Complete as-Built Records . Complete the Systems Manual . Turn over To Owner . Update set-points, calibration, and system changes ( POST-ACCEPTANCE ) |
