Design review, installation observation, functional testing, and issue tracking used to verify that selected building systems operate as intended.
Request a proposalIn plain terms
Commissioning establishes what selected systems are expected to do, then documents whether the installed systems can do it. Equipment startup is only one part of that process. The building also needs coordinated controls, functional testing, usable documentation, and a clear record of unresolved issues.
Scope, requirements & reporting
ASHRAE Guideline 0 and Standard 202 provide a framework for commissioning new buildings and systems. The Owner’s Project Requirements describe the performance the owner expects; the Basis of Design explains the design response. The commissioning plan assigns responsibilities and establishes how performance will be verified.
A system may start successfully yet fail to respond correctly to schedules, sensors, load changes, or other systems. The scope should establish operating modes, acceptance criteria, required records, issue resolution, and any deferred seasonal testing. KOW can coordinate design review, observations, functional testing, and the resulting documentation.
An owner’s commissioning scope, an energy-code requirement, and a green-building certification requirement can overlap without being identical. Existing-building retro-commissioning also has a different starting point from new construction. Confirm the governing requirements and covered systems before assigning responsibilities or pricing the work.
The commissioning record should include the agreed requirements, selected systems, test procedures, observed results, issues log, corrections, retesting, and remaining seasonal tests. A signed equipment startup sheet is not evidence that interacting systems respond correctly under different operating conditions. Establish responsibility for controls adjustments and corrective work in advance.
Decisions supported
Are the systems installed and operating in alignment with project requirements?
What deficiencies or coordination issues remain?
Are testing, documentation, and operator training complete?
What corrective actions should be tracked through closeout?
Typical scope
The final scope follows the property, transaction, program, client requirements, and information available. Typical elements include:
Process
Confirm the property or project, intended use, reliance parties, schedule, available information, and required deliverable.
Review the documents, identify gaps, and coordinate the people and access needed to complete the scope.
Perform the observations, analysis, interviews, and specialist coordination called for by the assignment.
Separate material findings from background information and state the basis, limitations, open items, and follow-up clearly.
Common assignments
Commissioning support from design review through functional testing and closeout.
Investigation of operational issues and opportunities to improve system performance.
Documentation and verification organized around applicable requirements.
Frequently asked
Startup establishes that equipment can operate. Functional testing evaluates the specified sequences and responses, including how components work together under relevant modes and conditions.
No. TAB establishes and documents system flows and balance. Commissioning uses relevant records and testing to evaluate broader functional performance; the scopes should be coordinated.
Record the condition and acceptance criterion, assign correction responsibility, and retest as required. An unresolved issue should remain visible in the final report.
Some checks may need deferred seasonal testing. Document what remains, when it will be tested, and who is responsible rather than implying the deferred work is already complete.
Commissioning reviews and documents whether selected systems are designed, installed, started, controlled, tested, and capable of operating in accordance with the agreed project requirements.
Early involvement allows commissioning requirements, responsibilities, documentation, and testing to be incorporated before construction and closeout decisions become harder to change.
