NEBB Building Systems Commissioning Certified Professional flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Owner's Project Requirements

The written document defining the owner's intended use, performance criteria, schedules, and documentation needs; it is the benchmark against which all commissioning verification is measured throughout the project.

Basis of Design

A document recording design assumptions, system selection rationale, calculations, and sequences of operation, and explaining how the design satisfies each item in the Owner's Project Requirements.

Commissioning Plan

The project-specific document defining scope, team roles, schedule, documentation, test procedures, acceptance criteria, and reporting structure for the entire commissioning process from pre-design through occupancy.

Pre-Functional Checklist

A static verification form completed before functional testing that documents installation completeness, nameplate data, alignment, rotation, cleanliness, and sensor calibration for each component or system.

Functional Performance Test

A dynamic test that operates a system through its sequence of operations, including staging, safeties, interlocks, alarms, and failure modes, with calibrated instruments and recorded results against acceptance criteria.

Commissioning Authority

The independent party leading the commissioning process, reporting to the owner, with no conflict of interest in design or construction, responsible for findings, testing oversight, and the final report.

Issues Log

A tracked register of commissioning findings recording description, location, responsible party, date opened, severity, corrective action, and verified closure date for each item.

Seasonal or Deferred Testing

Testing that cannot be completed at acceptance because required conditions are absent, such as peak heating or cooling, scheduled for later completion and documented as an open item.

Systems Manual

The compiled operations and maintenance documentation delivered to the owner, including sequences of operation, setpoints, schedules, as-built controls information, and troubleshooting guidance for facility staff.

Substantial Completion

The project milestone at which the work is sufficiently complete for its intended use; commissioning prerequisites typically include closed critical issues, completed training, and delivered documentation.

Retro-Commissioning

A commissioning process applied to an existing building that was not commissioned when new, focused on identifying low-cost operational improvements and resolving deficiencies without major capital work.

Ongoing Commissioning

A continuous process using monitoring-based tools and periodic re-verification to sustain performance after initial commissioning, tracking trends and re-testing systems when operation drifts from intent.

Point-to-Point Check

A controls verification confirming each physical input and output is wired and addressed to the correct controller point, performed before functional testing of control sequences.

Sequence of Operations

The written control logic describing how equipment responds to setpoints, schedules, and conditions, including staging, safeties, interlocks, and alarms; it defines the expected behavior tested during functional performance.

Test Acceptance Criteria

Predefined measurable conditions, such as setpoint tolerance, airflow range, or response time, that a functional test must meet for the tested system to be accepted by the commissioning team.

Readiness Review

A construction-phase meeting confirming prerequisites are met - checklists complete, startup done, controls calibrated, test procedures approved - before functional performance testing begins.

Design Review Finding

A documented commissioning comment identifying a gap between the Basis of Design and Owner's Project Requirements or a constructability issue, resolved by the design engineer before construction proceeds.

Controls Integration Test

A functional test verifying communication and coordinated operation between separate control systems, such as BAS-to-fire-alarm shutdown, BAS-to-generator start, or chiller plant-to-BAS staging.

Calibrated Test Instrument

Measuring equipment with documented calibration traceable to a recognized standard, required for functional testing so recorded data are defensible and acceptance decisions are reliable.

Commissioning Specification

The contract language in Division 01 and technical sections defining contractor commissioning responsibilities, submittal requirements, test participation, training obligations, and schedule impacts.

Contractor Self-Test

Startup and checkout performed by the installing contractor and documented on pre-functional checklists, establishing that equipment is ready for independent functional performance testing by the commissioning team.

Final Commissioning Report

The closing deliverable summarizing scope, tests performed, results, issues and their resolution, deferred items, training completed, and a statement of systems verified against the Owner's Project Requirements.

Owner Training Verification

Documented confirmation that facility staff received instruction on operation, maintenance, and troubleshooting, with attendance records and agenda tied to the systems manual content.

Warranty Review

A near-end-of-warranty inspection and interview confirming systems still operate as commissioned, identifying failures or drift, and documenting corrective actions before warranty coverage expires.

Lessons Learned Session

A closing review with the project team capturing what worked and what did not in design, construction, and commissioning, producing recommendations for future projects and ongoing operation.

Airflow Measurement Station

A duct-mounted array of total and static pressure sensors producing an averaged flow signal; commissioning verifies its accuracy against a pitot-tube traverse and corrects the flow coefficient.

Pitot-Tube Traverse

A duct airflow measurement using a grid of velocity pressure readings across the duct cross-section, averaged to compute velocity and volume; used to verify installed airflow stations and fan capacity.

Economizer Functional Test

A test driving the economizer through changeover conditions to verify damper modulation, minimum position, actuator stroke, and lockout, confirming free cooling engages and disengages per the sequence.

Chiller Plant Staging Test

A functional test verifying automatic sequencing of chillers, pumps, and towers, including lead-lag rotation, capacity addition and removal, and safeties, with recorded flows, temperatures, and power.

VAV Box Functional Test

A test verifying airflow setpoint tracking, damper and reheat response, minimum and maximum airflow limits, and calibration of the airflow sensor at each terminal unit.

Trend Log Verification

Review of BAS trend data to confirm sequences operated as intended over time, capturing conditions that a short functional test cannot, such as cycling, staging, and night setback behavior.

Deferred Test Log

A register listing functional tests postponed for missing conditions, with the required condition, responsible party, planned date, and closure evidence, tracked until completed and reported.
