32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Commissioning Authority (CxA)
- The individual or entity responsible for planning, organizing, and leading the commissioning process, independent of the design and construction contracts for commissioned systems.
- Owner's Project Requirements
- A written document describing the functional requirements and expectations of the owner for how the facility and its systems will be used and operated.
- Basis of Design
- The designer's written record of assumptions, calculations, and decisions that document how the design satisfies the Owner's Project Requirements.
- Commissioning Plan
- A document defining Cx scope, team roles, schedule, communication protocols, test procedures, and deliverable formats, updated as the project evolves.
- ASHRAE Guideline 0
- The guideline that describes the commissioning process for new construction, renovation, and existing buildings, defining phases, roles, and deliverables.
- ASHRAE Standard 202
- The standard specifying minimum commissioning process requirements that can be adopted as code language for new buildings and major renovations.
- Pre-design Cx deliverables
- Initial Owner's Project Requirements, initial Commissioning Plan, and identification of systems to be commissioned, produced during the pre-design phase.
- Design review in Cx
- Comparison of the Basis of Design against the Owner's Project Requirements to confirm each requirement is addressed and to flag gaps.
- Measurable OPR criteria
- Quantitative requirements such as temperature setpoints, ventilation rates, and energy targets that become acceptance benchmarks for functional performance testing.
- OPR-BOD discrepancy log
- A tracked record of differences between Owner's Project Requirements and Basis of Design, with assigned responsibility and resolution status.
- Design review milestones
- Checkpoints at schematic design, design development, and construction documents where Cx design review is performed against the OPR.
- OPR change control
- Owner approval is required to update the OPR; the CxA then evaluates impacts on Cx scope, test procedures, and acceptance criteria.
- Cx specification section
- Typically Division 01 Section 01 91 00, defining contractor responsibilities, submittals, testing obligations, and schedule impacts for commissioning.
- Pre-functional checklist
- A document verifying installation, static conditions, and readiness of equipment before functional performance testing, completed by the contractor and verified by the CxA.
- Functional performance test
- A test demonstrating that systems and components operate interactively and meet the Owner's Project Requirements under specified conditions.
- FPT acceptance criteria
- Predefined measurable conditions and results that determine whether a functional performance test passes or fails.
- FPT test script content
- Prerequisites, instrumentation, step-by-step procedures, acceptance criteria, and documentation requirements for a functional performance test.
- Failure-mode testing
- FPT coverage of alarms, safeties, interlocks, and off-design conditions to confirm the system responds as specified when components fail.
- Deficiency log
- A tracked record of failed tests and installation issues with responsible party, due date, and retest status until resolution.
- FPT prerequisites
- Conditions required before functional testing, including completed pre-functional checklists, calibrated instruments, trained operators, and stable system conditions.
- Submittal review for Cx
- CxA review of product data, shop drawings, and O&M data to confirm equipment and controls meet Basis of Design performance criteria.
- Cx schedule requirement
- The contractor must submit a construction Cx schedule and testing plan consistent with the Commissioning Plan and project schedule.
- Contractor Cx responsibilities
- Contractual obligations to participate in Cx activities, provide qualified personnel, complete checklists, and include Cx in subcontractor scopes.
- CxA independence requirement
- The Commissioning Authority must be independent of the design and construction contracts for commissioned systems to preserve objectivity.
- Seasonal testing
- Testing performed under conditions not achievable during initial FPT, such as peak heating, peak cooling, and shoulder-season changeover, within the warranty period.
- Training verification
- Confirmation that operator training occurred, documented through attendance records and evaluation of trainee understanding of operation and maintenance.
- Systems manual
- A compiled document containing OPR, BOD, equipment data, control sequences, as-built information, O&M procedures, and training records.
- Final commissioning report
- A document summarizing the Cx process, test results, unresolved issues, deferred seasonal testing, and the CxA's statement of compliance.
- Post-acceptance Cx
- Warranty-phase activities including seasonal testing completion, resolution of open issues, and periodic reviews of system performance.
- Lessons-learned feedback
- Information from the Cx process delivered to the owner for improving future projects and ongoing facility operation.
- Construction Cx site observation
- Periodic CxA site visits during construction to observe installation, track issues, and report progress to the owner.
- O&M manual requirement
- A specification requirement defining operation and maintenance documentation deliverables so training and documentation are contractually enforceable.
