Commissioning (Cx)

A quality-focused process that verifies and documents that building systems and assemblies perform interactively according to the owner's project requirements and the design intent, beginning in pre-design and continuing through occupancy.

Pre-Design Phase

The earliest project stage where commissioning scope, budget, schedule, and the owner's project requirements are established before schematic design work begins.

Design Review

A structured examination of design documents by the commissioning authority to confirm the design satisfies the owner's project requirements and supports verifiable, testable system performance.

Related: Basis of Design (BOD), Commissioning Specification
Commissioning Specification

Contract language in the construction documents that assigns commissioning duties to the contractor, defines submittal and testing requirements, and establishes acceptance conditions tied to commissioning.

Related: Design Review, Pre-Functional Checklist
Construction Checklist

A documented verification, completed during installation, that equipment and systems are installed correctly and ready for testing, capturing observations before functional performance testing begins.

Related: Pre-Functional Checklist, Installation Verification
Pre-Functional Checklist

A form used to confirm static conditions such as installation, cleanliness, labeling, calibration, and electrical safety before energizing or running equipment for functional testing.

Related: Construction Checklist, Functional Performance Test (FPT)
Functional Performance Test (FPT)

A scripted, witnessed test that operates systems under specified conditions to demonstrate that components and systems respond correctly and meet the owner's project requirements.

Related: Test Procedure, Seasonal Testing, Pre-Functional Checklist
Test Procedure

A written step-by-step script listing prerequisites, actions, expected responses, instrumentation, and acceptance criteria used to conduct and document a functional performance test consistently.

Related: Functional Performance Test (FPT), Acceptance Criteria
Acceptance Criteria

The measurable thresholds or conditions, defined in advance, that a system or component must satisfy to be judged as passing a test and accepted by the owner.

Related: Test Procedure, Seasonal Testing
Seasonal Testing

Deferred or supplemental testing performed during different weather conditions to verify performance of systems such as heating, cooling, and economizers that cannot be fully exercised at one time.

Related: Functional Performance Test (FPT), Acceptance Criteria
Installation Verification

The process of confirming that equipment, materials, and systems are installed in accordance with the contract documents and manufacturer instructions before testing and acceptance.

Related: Construction Checklist, Issues Log
Issues Log

A tracked record of deficiencies, questions, and nonconformance items discovered during commissioning, including assignment, status, and resolution, used to drive closeout.

Related: Commissioning Report, Installation Verification
Commissioning Report

The final record summarizing commissioning activities, test results, unresolved issues, and conclusions, documenting that systems were verified and accepted by the owner.

Related: Issues Log, Systems Manual
Systems Manual

A consolidated reference for building operators containing system descriptions, control sequences, equipment data, maintenance requirements, and commissioning records needed to operate the facility.

Related: Commissioning Report, Training Plan
Training Plan

A structured schedule that identifies who needs training, on which systems, delivered by whom, with content, timing, and verification methods for operator competence.

Related: Systems Manual, O&M Manuals

Retro-Commissioning (RCx)

A commissioning process applied to existing buildings that are not undergoing major renovation, aimed at identifying low-cost operational improvements and restoring performance to intended levels.

Related: Commissioning (Cx), Measurement and Verification (M&V)
Measurement and Verification (M&V)

A systematic approach to quantifying energy and cost savings from efficiency measures using metered data, engineering calculations, and agreed baselines and methods.

Related: Retro-Commissioning (RCx), Acceptance Criteria
Enhanced Commissioning

A scope of commissioning beyond the base level that adds activities such as design review, contractor submittal review, and post-occupancy monitoring to strengthen quality assurance.

Related: Commissioning (Cx), Design Review
Continuous Commissioning

An ongoing process of monitoring building performance data, identifying faults, and making adjustments over the life of a facility to sustain efficient operation.

Related: Retro-Commissioning (RCx), Measurement and Verification (M&V)
